The rsconnect-python CLI#
This package provides a CLI (command-line interface) for interacting
with and deploying to Posit Connect. This is also used by the
rsconnect-jupyter
package to deploy
Jupyter notebooks via the Jupyter web console. Many types of content supported by Posit
Connect may be deployed by this package, including WSGI-style APIs, Dash, Streamlit, and
Bokeh applications.
Content types not directly supported by the CLI may also be deployed if they include a
prepared manifest.json
file. See "Deploying R or Other
Content" for details.
Deploying Python Content to Posit Connect#
Posit Connect supports the deployment of Jupyter notebooks, Python APIs (such as those based on Flask or FastAPI) and apps (such as Dash, Streamlit, and Bokeh apps). Much like deploying R content to Posit Connect, there are some caveats to understand when replicating your environment on the Posit Connect server:
Posit Connect insists on matching <MAJOR.MINOR>
versions of Python. For example,
a server with only Python 3.9 installed will fail to match content deployed with
Python 3.8. Your administrator may also enable exact Python version matching which
will be stricter and require matching major, minor, and patch versions. For more
information see the Posit Connect Admin Guide chapter titled Python Version
Matching.
Installation#
To install rsconnect-python
from PYPI, you may use any python package manager such as
pip:
pip install rsconnect-python
You may also build and install a wheel directly from a repository clone:
git clone https://github.com/posit-dev/rsconnect-python.git
cd rsconnect-python
pip install pipenv
make dist
pip install ./dist/rsconnect_python-*.whl
Using the rsconnect CLI#
Here's an example command that deploys a Jupyter notebook to Posit Connect.
rsconnect deploy notebook \
--server https://connect.example.org \
--api-key my-api-key \
my-notebook.ipynb
Note
The examples here use long command line options, but there are short
options (-s
, -k
, etc.) available also. Run rsconnect deploy notebook --help
for details.
Setting up rsconnect
CLI auto-completion#
If you would like to use your shell's tab completion support with the rsconnect
command, use the command below for the shell you are using.
bash
#
If you are using the bash
shell, use this to enable tab completion.
#~/.bashrc
eval "$(_RSCONNECT_COMPLETE=source rsconnect)"
zsh
#
If you are using the zsh
shell, use this to enable tab completion.
#~/.zshrc
eval "$(_RSCONNECT_COMPLETE=source_zsh rsconnect)"
If you get command not found: compdef
, you need to add the following lines to your
.zshrc
before the completion setup:
#~/.zshrc
autoload -Uz compinit
compinit
Managing Server Information#
The information used by the rsconnect
command to communicate with a Posit Connect
server can be tedious to repeat on every command. To help, the CLI supports the idea
of saving this information, making it usable by a simple nickname.
Warning
One item of information saved is the API key used to authenticate with Posit Connect. Although the file where this information is saved is marked as accessible by the owner only, it's important to remember that the key is present in the file as plain text so care must be taken to prevent any unauthorized access to the server information file.
TLS Support and Posit Connect#
Usually, a Posit Connect server will be set up to be accessed in a secure manner,
using the https
protocol rather than simple http
. If Posit Connect is set up
with a self-signed certificate, you will need to include the --insecure
flag on
all commands. If Posit Connect is set up to require a client-side certificate chain,
you will need to include the --cacert
option that points to your certificate
authority (CA) trusted certificates file. Both of these options can be saved along
with the URL and API Key for a server.
Note
When certificate information is saved for the server, the specified file is read and its contents are saved under the server's nickname. If the CA file's contents are ever changed, you will need to add the server information again.
See the Network Options section for more details about these options.
Remembering Server Information#
Use the add
command to store information about a Posit Connect server:
rsconnect add \
--api-key my-api-key \
--server https://connect.example.org \
--name myserver
Note
The rsconnect
CLI will verify that the serve URL and API key
are valid. If either is found not to be, no information will be saved.
If any of the access information for the server changes, simply rerun the
add
command with the new information and it will replace the original
information.
Once the server's information is saved, you can refer to it by its nickname:
rsconnect deploy notebook --name myserver my-notebook.ipynb
If there is information for only one server saved, this will work too:
rsconnect deploy notebook my-notebook.ipynb
Listing Server Information#
You can see the list of saved server information with:
rsconnect list
Removing Server Information#
You can remove information about a server with:
rsconnect remove --name myserver
Removing may be done by its nickname (--name
) or URL (--server
).
Verifying Server Information#
You can verify that a URL refers to a running instance of Posit Connect by using
the details
command:
rsconnect details --server https://connect.example.org
In this form, rsconnect
will only tell you whether the URL given does, in fact, refer
to a running Posit Connect instance. If you include a valid API key:
rsconnect details --server https://connect.example.org --api-key my-api-key
the tool will provide the version of Posit Connect (if the server is configured to divulge that information) and environmental information including versions of Python that are installed on the server.
You can also use nicknames with the details
command if you want to verify that the
stored information is still valid.
Notebook Deployment Options#
There are a variety of options available to you when deploying a Jupyter notebook to Posit Connect.
Including Extra Files#
You can include extra files in the deployment bundle to make them available when your notebook is run by the Posit Connect server. Just specify them on the command line after the notebook file:
rsconnect deploy notebook my-notebook.ipynb data.csv
Package Dependencies#
If a requirements.txt
file exists in the same directory as the notebook file, it will
be included in the bundle. It must specify the package dependencies needed to execute
the notebook. Posit Connect will reconstruct the Python environment using the
specified package list.
If there is no requirements.txt
file or the --force-generate
option is specified,
the package dependencies will be determined from the current Python environment, or
from an alternative Python executable specified via the --python
option:
rsconnect deploy notebook --python /path/to/python my-notebook.ipynb
You can see the packages list that will be included by running pip list --format=freeze
yourself,
ensuring that you use the same Python that you use to run your Jupyter Notebook:
/path/to/python -m pip list --format=freeze
Static (Snapshot) Deployment#
By default, rsconnect
deploys the original notebook with all its source code. This
enables the Posit Connect server to re-run the notebook upon request or on a schedule.
If you just want to publish an HTML snapshot of the notebook, you can use the --static
option. This will cause rsconnect
to execute your notebook locally to produce the HTML
file, then publish the HTML file to the Posit Connect server:
rsconnect deploy notebook --static my-notebook.ipynb
Creating a Manifest for Future Deployment#
You can create a manifest.json
file for a Jupyter Notebook, then use that manifest
in a later deployment. Use the write-manifest
command to do this.
The write-manifest
command will also create a requirements.txt
file, if it does
not already exist or the --force-generate
option is specified. It will contain the
package dependencies from the current Python environment, or from an alternative
Python executable specified in the --python
option.
Here is an example of the write-manifest
command:
rsconnect write-manifest notebook my-notebook.ipynb
Note
Manifests for static (pre-rendered) notebooks cannot be created.
API/Application Deployment Options#
You can deploy a variety of APIs and applications using sub-commands of the
rsconnect deploy
command.
api
: WSGI-compliant APIs (e.g.,bottle
,falcon
,flask
,flask-restx
,flasgger
,pycnic
).flask
: Flask APIs (Note:flask
is an alias ofapi
.).fastapi
: ASGI-compliant APIs (e.g,fastapi
,quart
,sanic
,starlette
)dash
: Python Dash appsstreamlit
: Streamlit appsbokeh
: Bokeh server apps
All options below apply equally to the api
, fastapi
, dash
, streamlit
,
and bokeh
sub-commands.
Including Extra Files#
You can include extra files in the deployment bundle to make them available when your API or application is run by the Posit Connect server. Just specify them on the command line after the API or application directory:
rsconnect deploy api flask-api/ data.csv
Since deploying an API or application starts at a directory level, there will be times
when some files under that directory subtree should not be included in the deployment
or manifest. Use the --exclude
option to specify files or directories to exclude.
rsconnect deploy dash --exclude dash-app-venv --exclude TODO.txt dash-app/
You can exclude a directory by naming it:
rsconnect deploy dash --exclude dash-app-venv --exclude output/ dash-app/
The --exclude
option may be repeated, and may include a glob pattern.
You should always quote a glob pattern so that it will be passed to rsconnect
as-is
instead of letting the shell expand it. If a file is specifically listed as an extra
file that also matches an exclusion pattern, the file will still be included in the
deployment (i.e., extra files take precedence).
rsconnect deploy dash --exclude dash-app-venv --exclude “*.txt” dash-app/
The following shows an example of an extra file taking precedence:
rsconnect deploy dash --exclude “*.csv” dash-app/ important_data.csv
The "**
" glob pattern will recursively match all files and directories,
while "*
" only matches files. The "**
" pattern is useful with complicated
project hierarchies where enumerating the included files is simpler than
listing the exclusions.
rsconnect deploy quarto . _quarto.yml index.qmd requirements.txt --exclude "**"
Some directories are excluded by default, to prevent bundling and uploading files that are not needed or might interfere with the deployment process:
.Rproj.user
.env
.git
.svn
.venv
__pycache__
env
packrat
renv
rsconnect-python
rsconnect
venv
Any directory that appears to be a Python virtual environment (by containing
bin/python
) will also be excluded.
Package Dependencies#
If a requirements.txt
file exists in the API/application directory, it will be
included in the bundle. It must specify the package dependencies needed to execute
the API or application. Posit Connect will reconstruct the Python environment using
the specified package list.
If there is no requirements.txt
file or the --force-generate
option is specified,
the package dependencies will be determined from the current Python environment, or
from an alternative Python executable specified via the --python
option:
rsconnect deploy api --python /path/to/python my-api/
You can see the packages list that will be included by running pip list --format=freeze
yourself,
ensuring that you use the same Python that you use to run your API or application:
/path/to/python -m pip list --format=freeze
Creating a Manifest for Future Deployment#
You can create a manifest.json
file for an API or application, then use that
manifest in a later deployment. Use the write-manifest
command to do this.
The write-manifest
command will also create a requirements.txt
file, if it does
not already exist or the --force-generate
option is specified. It will contain
the package dependencies from the current Python environment, or from an alternative
Python executable specified in the --python
option.
Here is an example of the write-manifest
command:
rsconnect write-manifest api my-api/
Deploying R or Other Content#
You can deploy other content that has an existing Posit Connect manifest.json
file. For example, if you download and unpack a source bundle from Posit Connect,
you can deploy the resulting directory. The options are similar to notebook or
API/application deployment; see rsconnect deploy manifest --help
for details.
Here is an example of the deploy manifest
command:
rsconnect deploy manifest /path/to/manifest.json
Note
In this case, the existing content is deployed as-is. Python environment inspection and notebook pre-rendering, if needed, are assumed to be done already and represented in the manifest.
The argument to deploy manifest
may also be a directory so long as that directory
contains a manifest.json
file.
If you have R content but don't have a manifest.json
file, you can use the RStudio
IDE to create the manifest. See the help for the rsconnect::writeManifest
R function:
install.packages('rsconnect')
library(rsconnect)
?rsconnect::writeManifest
Options for All Types of Deployments#
These options apply to any type of content deployment.
Title#
The title of the deployed content is, by default, derived from the filename. For
example, if you deploy my-notebook.ipynb
, the title will be my-notebook
. To change
this, use the --title
option:
rsconnect deploy notebook --title "My Notebook" my-notebook.ipynb
When using rsconnect deploy api
, rsconnect deploy fastapi
, rsconnect deploy dash
,
rsconnect deploy streamlit
, or rsconnect deploy bokeh
, the title is derived from the directory
containing the API or application.
When using rsconnect deploy manifest
, the title is derived from the primary
filename referenced in the manifest.
Verification After Deployment#
After deploying your content, rsconnect accesses the deployed content
to verify that the deployment is live. This is done with a GET
request
to the content, without parameters. The request is
considered successful if there isn't a 5xx code returned. Errors like
400 Bad Request or 405 Method Not Allowed because not all apps support GET /
.
For cases where this is not desired, use the --no-verify
flag on the command line.
Environment variables#
You can set environment variables during deployment. Their names and values will be
passed to Posit Connect during deployment so you can use them in your code. Note that
if you are using rsconnect
to deploy to shinyapps.io, environment variable management
is not supported on that platform.
For example, if notebook.ipynb
contains
print(os.environ["MYVAR"])
You can set the value of MYVAR
that will be set when your code runs in Posit Connect
using the -E/--environment
option:
rsconnect deploy notebook --environment MYVAR='hello world' notebook.ipynb
To avoid exposing sensitive values on the command line, you can specify a variable without a value. In this case, it will use the value from the environment in which rsconnect-python is running:
export SECRET_KEY=12345
rsconnect deploy notebook --environment SECRET_KEY notebook.ipynb
If you specify environment variables when updating an existing deployment, new values will be set for the variables you provided. Other variables will remain unchanged. If you don't specify any variables, all of the existing variables will remain unchanged.
Environment variables are set on the content item before the content bundle is uploaded and deployed. If the deployment fails, the new environment variables will still take effect.
Network Options#
When specifying information that rsconnect
needs to be able to interact with Posit
Connect, you can tailor how transport layer security is performed.
TLS/SSL Certificates#
Posit Connect servers can be configured to use TLS/SSL. If your server's certificate
is trusted by your Jupyter Notebook server, API client or user's browser, then you
don't need to do anything special. You can test this out with the details
command:
rsconnect details \
--api-key my-api-key \
--server https://connect.example.org:3939
If this fails with a TLS Certificate Validation error, then you have two options.
-
Provide the Root CA certificate that is at the root of the signing chain for your Posit Connect server. This will enable
rsconnect
to securely validate the server's TLS certificate.rsconnect details \ --api-key my-api-key \ --server https://connect.example.org \ --cacert /path/to/certificate.pem
-
Posit Connect is in "insecure mode". This disables TLS certificate verification, which results in a less secure connection.
rsconnect add \ --api-key my-api-key \ --server https://connect.example.org \ --insecure
Once you work out the combination of options that allow you to successfully work with
an instance of Posit Connect, you'll probably want to use the add
command to have
rsconnect
remember those options and allow you to just use a nickname.
Updating a Deployment#
If you deploy a file again to the same server, rsconnect
will update the previous
deployment. This means that you can keep running rsconnect deploy notebook my-notebook.ipynb
as you develop new versions of your notebook. The same applies to other Python content
types.
Forcing a New Deployment#
To bypass this behavior and force a new deployment, use the --new
option:
rsconnect deploy dash --new my-app/
Updating a Different Deployment#
If you want to update an existing deployment but don't have the saved deployment data, you can provide the app's numeric ID or GUID on the command line:
rsconnect deploy notebook --app-id 123456 my-notebook.ipynb
You must be the owner of the target deployment, or a collaborator with permission to change the content. The type of content (static notebook, notebook with source code, API, or application) must match the existing deployment.
Note
There is no confirmation required to update a deployment. If you do so accidentally, use the "Source Versions" dialog in the Posit Connect dashboard to activate the previous version and remove the erroneous one.
Finding the App ID#
The App ID associated with a piece of content you have previously deployed from the
rsconnect
command line interface can be found easily by querying the deployment
information using the info
command. For more information, see the
Showing the Deployment Information section.
If the content was deployed elsewhere or info
does not return the correct App ID,
but you can open the content on Posit Connect, find the content and open it in a
browser. The URL in your browser's location bar will contain #/apps/NNN
where NNN
is your App ID. The GUID identifier for the app may be found on the Info tab for
the content in the Posit Connect UI.
Showing the Deployment Information#
You can see the information that the rsconnect
command has saved for the most recent
deployment with the info
command:
rsconnect info my-notebook.ipynb
If you have deployed to multiple servers, the most recent deployment information for each server will be shown. This command also displays the path to the file where the deployment data is stored.
Stored Information Files#
Stored information files are stored in a platform-specific directory:
Platform | Location |
---|---|
Mac | $HOME/Library/Application Support/rsconnect-python/ |
Linux | $HOME/.rsconnect-python/ or $XDG_CONFIG_HOME/rsconnect-python/ |
Windows | $APPDATA/rsconnect-python |
Remembered server information is stored in the servers.json
file in that directory.
Deployment Data#
After a deployment is completed, information about the deployment is saved
to enable later redeployment. This data is stored alongside the deployed file,
in an rsconnect-python
subdirectory, if possible. If that location is not writable
during deployment, then the deployment data will be stored in the global configuration
directory specified above.
Hide Jupyter Notebook Input Code Cells#
The user can render a Jupyter notebook without its corresponding input code cells by passing the '--hide-all-input' flag through the cli:
rsconnect deploy notebook \
--server https://connect.example.org \
--api-key my-api-key \
--hide-all-input \
my-notebook.ipynb
To selectively hide input cells in a Jupyter notebook, the user needs to follow a two step process: 1. tag cells with the 'hide_input' tag, 2. then pass the ' --hide-tagged-input' flag through the cli:
rsconnect deploy notebook \
--server https://connect.example.org \
--api-key my-api-key \
--hide-tagged-input \
my-notebook.ipynb
By default, rsconnect-python does not install Jupyter notebook related depenencies. These dependencies are installed via rsconnect-jupyter. When the user is using the hide input features in rsconnect-python by itself without rsconnect-jupyter, he/she needs to install the following package depenecies:
notebook
nbformat
nbconvert>=5.6.1
Content subcommands#
rsconnect-python supports multiple options for interacting with Posit Connect's
/v1/content
API. Both administrators and publishers can use the content subcommands
to search, download, and rebuild content on Posit Connect without needing to access the
dashboard from a browser.
Note
The rsconnect content
CLI subcommands are intended to be easily scriptable.
The default output format is JSON
so that the results can be easily piped into
other command line utilities like jq
for further post-processing.
rsconnect content --help

Content Build#
Note
The rsconnect content build
subcommand requires Posit Connect >= 2021.11.1
Posit Connect caches R and Python packages in the configured
Server.DataDir
.
Under certain circumstances (examples below), these package caches can become stale
and need to be rebuilt. This refresh automatically occurs when a Posit Connect
user visits the content. You may wish to refresh some content before it is visited
because it is high priority or is not visited frequently (API content, emailed reports).
In these cases, it is possible to preemptively build specific content items using
the rsconnect content build
subcommands. This way the user does not have to pay
the build cost when the content is accessed next.
The following are some common scenarios where performing a content build might be necessary:
- OS upgrade
- changes to gcc or libc libraries
- changes to Python or R installations
- switching from source to binary package repositories or vice versa
Note
The content build
command is non-destructive, meaning that it does nothing to purge
existing packrat/python package caches before a build. If you have an
existing cache, it should be cleared prior to starting a content build.
See the migration documentation for details.
Note
You may use the rsconnect content search
subcommand to help
identify high priority content items to build.
rsconnect content build --help
Usage: rsconnect content build [OPTIONS] COMMAND [ARGS]...
Build content on Posit Connect. Requires Connect >= 2021.11.1
Options:
--help Show this message and exit.
Commands:
add Mark a content item for build. Use `build run` to invoke the build
on the Connect server.
history Get the build history for a content item.
logs Print the logs for a content build.
ls List the content items that are being tracked for build on a given
Connect server.
rm Remove a content item from the list of content that are tracked for
build. Use `build ls` to view the tracked content.
run Start building content on a given Connect server.
To build a specific content item, first add
it to the list of content that is
"tracked" for building using its GUID.
Note
Metadata for "tracked" content items is stored in a local directory called
rsconnect-build
which will be automatically created in your current working directory.
You may set the environment variable CONNECT_CONTENT_BUILD_DIR
to override this directory location.
rsconnect content build add --guid 4ffc819c-065c-420c-88eb-332db1133317
Note
See this section for
an example of how to add multiple content items in bulk, from the results
of a rsconnect content search
command.
To view all currently "tracked" content items, use the rsconnect content build ls
subcommand.
rsconnect content build ls
To view only the "tracked" content items that have not yet been built, use the --status NEEDS_BUILD
flag.
rsconnect content build ls --status NEEDS_BUILD
Once the content items have been added, you may initiate a build
using the rsconnect content build run
subcommand. This command will attempt to
build all "tracked" content that has the status NEEDS_BUILD
.
To re-run failed builds, use
rsconnect content build run --retry
. This will build all tracked content in any of the following states:[NEEDS_BUILD, ABORTED, ERROR, RUNNING]
.
rsconnect content build run

Common Usage Examples#
Searching for content#
The following are some examples of how publishers might use the
rsconnect content search
subcommand to find content on Posit Connect.
By default, the rsconnect content search
command will return metadata for ALL
of the content on a Posit Connect server, both published and unpublished content.
Note
When using the --r-version
and --py-version
flags, users should
make sure to quote the arguments to avoid conflicting with your shell. For
example, bash would interpret --py-version >3.0.0
as a shell redirect because of the
unquoted >
character.
# return only published content
rsconnect content search --published
# return only unpublished content
rsconnect content search --unpublished
# return published content where the python version is at least 3.9.0
rsconnect content search --published --py-version ">=3.9.0"
# return published content where the R version is exactly 3.6.3
rsconnect content search --published --r-version "==3.6.3"
# return published content where the content type is a static RMD
rsconnect content search --content-type rmd-static
# return published content where the content type is either shiny OR fast-api
rsconnect content search --content-type shiny --content-type python-fastapi
# return all content, published or unpublished, where the title contains the
# text "Stock Report"
rsconnect content search --title-contains "Stock Report"
# return published content, results are ordered by when the content was last
# deployed
rsconnect content search --published --order-by last_deployed
# return published content, results are ordered by when the content was
# created
rsconnect content search --published --order-by created
Finding r and python versions#
One common use for the search
command might be to find the versions of
r and python that are currently in use on your Posit Connect server before a migration.
# search for all published content and print the unique r and python version
# combinations
rsconnect content search --published | jq -c '.[] | {py_version,r_version}' | sort |
uniq
# {"py_version":"3.8.2","r_version":"3.5.3"}
# {"py_version":"3.8.2","r_version":"3.6.3"}
# {"py_version":"3.8.2","r_version":null}
# {"py_version":null,"r_version":"3.5.3"}
# {"py_version":null,"r_version":"3.6.3"}
# {"py_version":null,"r_version":null}
Finding recently deployed content#
# return only the 10 most recently deployed content items
rsconnect content search \
--order-by last_deployed \
--published | jq -c 'limit(10; .[]) | { guid, last_deployed_time }'
# {"guid":"4ffc819c-065c-420c-88eb-332db1133317","last_deployed_time":"2021-12-02T18:09:11Z"}
# {"guid":"aa2603f8-1988-484f-a335-193f2c57e6c4","last_deployed_time":"2021-12-01T20:56:07Z"}
# {"guid":"051252f0-4f70-438f-9be1-d818a3b5f8d9","last_deployed_time":"2021-12-01T20:37:01Z"}
# {"guid":"015143da-b75f-407c-81b1-99c4a724341e","last_deployed_time":"2021-11-30T16:56:21Z"}

Add to build from search results#
One common use case might be to rsconnect content build add
content for build
based on the results of a rsconnect content search
. For example:
# search for all API type content, then
# for each guid, add it to the "tracked" content items
for guid in $(rsconnect content search \
--published \
--content-type python-api \
--content-type api | jq -r '.[].guid'); do
rsconnect content build add --guid $guid
done
Adding content items one at a time can be a slow operation. This is because
rsconnect content build add
must fetch metadata for each content item before it
is added to the "tracked" content items. By providing multiple --guid
arguments
to the rsconnect content build add
subcommand, we can fetch metadata for multiple content items
in a single api call, which speeds up the operation significantly.
# write the guid of every published content item to a file called guids.txt
rsconnect content search --published | jq '.[].guid' > guids.txt
# bulk-add from the guids.txt with a single `rsconnect content build add` command
xargs printf -- '-g %s\n' < guids.txt | xargs rsconnect content build add
Programmatic Provisioning#
Posit Connect supports the programmatic bootstrapping of an administrator API key
for scripted provisioning tasks. This process is supported by the rsconnect bootstrap
command,
which uses a JSON Web Token to request an initial API key from a fresh Connect instance.
rsconnect bootstrap \
--server https://connect.example.org:3939 \
--jwt-keypath /path/to/secret.key
A full description on how to use rsconnect bootstrap
in a provisioning workflow is provided in the Connect administrator guide's
programmatic provisioning documentation.
Server Administration Tasks#
Starting with the 2023.05 edition of Posit Connect, rsconnect-python
can be
used to perform certain server administration tasks, such as instance managing
runtime caches. For more information on runtime caches in Posit Connect, see the
Connect Admin Guide's section on runtime
caches.
Examples in this section will use --name myserver
to stand in for your Connect
server information. See Managing Server
Information above for more details.
Enumerate Runtime Caches#
New in Connect 2023.05
Use the command below to enumerate runtime caches on a Connect server. The command will output a JSON object containing a list of runtime caches . Each cache entry will contain the following information:
language
: The language of content that uses the cache, either R or Python.version
: The language version of the content that uses the cache.image_name
: The execution environment of the cache. The stringLocal
denotes native execution. For Connect instances that use off-host execution, the name of the image that uses the cache will be displayed.
rsconnect system caches list --name myserver
# {
# "caches": [
# {
# "language": "R",
# "version": "3.6.3",
# "image_name": "Local"
# },
# {
# "language": "Python",
# "version": "3.9.5",
# "image_name": "Local"
# },
# {
# "language": "R",
# "version": "3.6.3",
# "image_name": "rstudio/content-base:r3.6.3-py3.9.5-bionic"
# },
# {
# "language": "Python",
# "version": "3.9.5",
# "image_name": "rstudio/content-base:r3.6.3-py3.9.5-bionic"
# }
# ]
# }
Note
The image_name
field returned by the server will use sanitized versions
of names.
Delete Runtime Caches#
New in Connect 2023.05
When Connect's execution environment changes, runtime caches may be invalidated.
In these cases, you will need to delete the affected runtime caches using the
system caches delete
command.
Warning
After deleting a cache, the first time affected content is visited, Connect
will need to reconstruct its environment. This can take a long time. To
mitigate this, you can use the content build
command to
rebuild affected content ahead of time. You may want to do this just for
high-priority content, or for all content.
To delete a runtime cache, call the system caches delete
command, specifying a
Connect server, as well as the language (-l, --language
), version (-V,
--version
), and image name (-I, --image-name
) for the cache you wish to
delete. Deleting a large cache might take a while. The command will wait for
Connect to finish the task.
Use the following parameters specify the target cache:
language
(required) must nameR
orPython
. It is case-insensitive.version
(required) must be a three-part version number, e.g.3.8.12
.image-name
(optional) defaults toLocal
, which targets caches used for natively-executed content. Off-host images can be specified using either the literal image name or the sanitized name returned by thelist
command.
Use the dry run flag (-d, --dry-run
) to surface any errors ahead of
deletion.
rsconnect system caches delete \
--name myserver \
--language Python \
--version 3.9.5 \
--image-name rstudio/content-base:r3.6.3-py3.9.5-bionic \
--dry-run
# Dry run finished
rsconnect system caches delete \
--name myserver \
--language Python \
--version 3.9.5 \
--image-name rstudio/content-base:r3.6.3-py3.9.5-bionic
# Deleting runtime cache...
# Successfully deleted runtime cache
You should run these commands for each cache you wish to delete.
