Login issue in rstudio

[AritraDey-Dev]

Bug Description

There is currently a problem logging into RStudio using the credentials:

• username: carya
• password: illinois

PR #3527 introduces some changes to mitigate this issue.However, even after that fix, login may still fail This issue arises from recent changes in the upstream rocker image, which affect how users and permissions are handled inside the RStudio container.

Details

• Upstream Changes in rocker Image:
  • Recent versions of the rocker/rstudio image automatically create a default user named rstudio.
  • This default user uses UID and GID 1000, which conflicts with the creation of the custom user carya during container initialization as from the env file it takes UID and GID as 1000.
• Conflict with PEcAn Custom User Creation:
  • In the PEcAn Docker setup, the script rstudio.sh expects a USER argument https://github.com/PecanProject/pecan/blob/38df06107037b24eacc02aec061966f40cf49ded/docker/base/rstudio.sh#L5 But we are passing DEFAULT_USER from docker compose environment.

To Reproduce

Try to login to rstudio with username with the creds given above.

Expected behavior

RStudio login with username carya and password illinois should work, and /home/carya should contain the pecan folder.

workaround

Setting UID=1001 and GID=1001 for carya in docker-compose.yml avoids conflict with the default rstudio user (UID 1000), though i am not sure this may introduce permission issues elsewhere that need further validation.

this only happens if the UID=1000 any other number will work.

The default is UID=1001 in the docker compose file, so you need to explicitly set the UID to 1000.
