Posit Connect provides flexibility over how uploaded content is configured and shared.
Each deployment in Posit Connect can have specific access controls which specify which users are allowed to view and/or edit that content.
The list of collaborators enumerates the users allowed to edit and help manage the settings for a given deployment. The content owner is always included as a collaborator. Collaborators must be either "publisher" or "administrator" accounts.
A viewer is able to view content. Any type of account can be made a viewer for a given piece of content. Choose from the following options.
- Anyone - no login required
Any visitor to Posit Connect will be able to view this content. This includes anonymous users who are not authenticated with the system.
- All users - login required
All Posit Connect accounts are permitted to view this content.
- Specific users or groups
Specific users (or groups of users) are allowed to view this content. Other users will not have access.
Limiting allowed viewership#
Some organizations want to restrict the types of access that publishers and administrators can assign to content.
These settings take the following values:
The most permissive access type. Allows all viewership permissions.
Permits only logged-in viewership options. This includes allowing the content owner and specific users and groups.
Content must explicitly enumerate specific users and groups.
There is not an access type that only allows the owner to view the content. Owner-only access is implemented as an empty access control list (ACL).
The following example requires publishers to constrain viewership by enumerating specific users and groups in access control lists. Publishers cannot grant access to all logged-in users or to anonymous, unauthenticated users. Administrators are allowed to configure any access type.
These values can be helpful to avoid accidentally exposing content too widely, while still allowing select individuals to publicize approved content.
; /etc/rstudio-connect/rstudio-connect.gcfg [Applications] MostPermissiveAccessType = acl AdminMostPermissiveAccessType = all
This next example prohibits content from being given unconstrained viewership. Content cannot be configured to allow anonymous, unauthenticated access. The restriction applies to both publishers and administrators.
Use this configuration when you want to require user login before accessing any content on Posit Connect.
; /etc/rstudio-connect/rstudio-connect.gcfg [Applications] MostPermissiveAccessType = logged_in
The access type of existing content is not automatically altered. The two access type settings limit which permissions may be given to content. This restriction is only enforced when content is created or modified.
All content receives a URL that includes its globally unique ID at at the time of
deployment -- something like
Connect administrative users can create "vanity paths" for content which make
the content available at an additional, customized URL.
This setting can be found at the bottom of the "Access" tab when editing a piece of content. There you can enter the path at which you want this content to be available and preview the complete URL. Once you "Save" your content, you'll be able to access your content at the new vanity URL.
Only administrators can manage vanity paths by default.
To allow publishers to create vanity paths for content items they own and
collaborate on, enable the
Vanity path restrictions#
Vanity URLs can not be nested inside of one another. So if a vanity URL
/finance/ already exists, you would not be able to create a new vanity URL
/finance/budget/. Sibling paths, such as:
/finance/quarterly/ may both exist concurrently.
Vanity URLs may include only alphanumeric characters, hyphens, underscores, and slashes.
The following path prefixes are prohibited in vanity URLs:
- The custom location for the Connect dashboard, configured by
You can use tags to organize content and make it easy for users to find content that they're interested in. To begin, create a tag schema in the "Tags" section of the Connect dashboard by creating one or more tag categories. Define some tags, which can be nested any number of levels deep.
For example, if your data scientists are creating reports covering different geographical areas, you could create a category called "Geographical Area". Then, you could create tags such as "Americas" or "Asia" and nest the tags "North America" and "South America" under "Americas".
Only administrators can create and edit the tag schema. Categories and tags can be added, deleted, and renamed. Once a tag or category is deleted, all tags nested under it are also deleted.
Collaborators can associate content with one or more tags in the "Tags" tab of the content settings sidebar. Users can filter by tags to discover content, as long as they have permission to view that content.
For example, if multiple reports analyze the same set of data, those reports could be tagged with some identifier, such as "FY2016 Q3" for the third quarter of the 2016 fiscal year. A report that analyzes the third and fourth quarter could be tagged with "FY2016 Q3" and "FY2016 Q4", and would appear when a user filters for either "FY2016 Q3" or "FY2016 Q4".
Content published to Posit Connect is encapsulated in a "bundle" that
contains the source code and data necessary to execute the content. An
application or report is updated by uploading a new bundle. Old bundles are
retained on disk until you reach the limit imposed by
at which point older bundles will be deleted.
Users can manage their own bundles in the Connect dashboard by clicking the "Source Versions" button. Collaborators can delete, download, activate, and view activation logs for their applications' bundles. Activating a different bundle is a way of "rolling back" or "rolling forward" to an older or newer version of your application, respectively.
Activating an alternative bundle for a Shiny application will cause new incoming users to be directed to the new version of the application but will not interrupt existing users of the application who are viewing the previously activated bundle. For reports, activating an alternate bundle will immediately render the newly activated bundle and promote it to be the authoritative version of that document. For parameterized reports, only the default variant will be rerendered; other instances of the report will not automatically be regenerated, but the next manual or scheduled update will be performed on the newly selected bundle.
When activating an alternative bundle for an API, existing requests will be serviced by processes already launched running the old code. New requests will be serviced by new processes running the new code.
Once content has been published to Posit Connect, the publisher may enter the "info" tab in the application settings pane and upload an image to be associated with the content.
Application images are stored in the server's data directory.
Application images can be viewed by anyone with permission to view the associated content.
Administrators cannot view images associated with content that they do not have access to. However, all administrators may change the visibility mode, or add themselves to the viewer list, for any piece of content. This ensures that the Administrator's act of giving themselves viewer privileges can be tracked in the server's audit logs.
Posit Connect will reject uploads of images larger than the
Applications.MaxAppImageSizeconfiguration setting value. By default, the server will tolerate images up to 10MB in size.
Posit Connect does no post-processing; images will be sent back to the user exactly as they were uploaded, and the Posit Connect dashboard will make its best effort to display them in a consistent manner.
The Posit Connect dashboard will attempt to cache images in an efficient and consistent manner. Every time the image is displayed, the dashboard will check the server for a newer version of the image, and accept its cached version if a newer image does not exist.
