SHINYPRIXY_USERNAME is not passed when using minimum-seats-available

[faridovski]

In order to shorten the startup time of my shiny apps, I have activated minimum-seats-available. I realized that the allocated pod does not contain the ENV variable (SHINYPROXY_USERNAME).
More details:

• shinyproxy version 3.1.1
• container backend: k8s cluster
• Authentication: OpenId (keycloak)

Following version 3.1.0, I had this same issue.

I figured out how to extract the USERID and the USERGROUP from this and other resources:
https://support.openanalytics.eu/t/passing-username-and-groups-as-http-headers-in-3-1-0/2747/2

Today, I extract the USERID in our application with

shinyproxy_user_id <- session$request$HTTP_X_SP_USERID

Hope this helps

It is indeed specific to the pre-initialized containers, as documented in https://www.shinyproxy.io/documentation/configuration/#container-pre-initialization-and-sharing (see "Before using this feature, make sure to understand the following...")
