more user craziness with docker
Should do something about rstudio script when running as a non-root user…. Fixed! Requires changing user more carefully; we cannot simply delete the existing user.
When using a docker image with a non-root default user, we can launch a container as root by giving root’s UID instead with the
--user 0 flag. (Note that we can do this with other UIDs as well, though it produces a troublesome unnamed user when the userid hasn’t been assigned to a user name).
- RStudio image now completely configures default user in the Dockerfile, such that userconf.sh need only configure custom users. See userconf.sh. We now do:
usermod -l rstudio docker \ && usermod -m -d /home/rstudio rstudio \ && groupmod -n rstudio docker
userdel which causes issues if we launch as that user. Note, this means containers built on
rstudio have only the user
rstudio available and not the
docker user, unless explicitly added/renamed. Avoids issues like multiple home directories/unpredictable home directory name as well (Since RStudio-server wants to open in home dir and not in a user-owned root directory like
/data like most other apps would use.) - RStudio must still be launched as root (see RStudio issue), so a Dockerfile with non-root user must use the
--user 0 flag or run
rserver or the default
- Configure supervisord.conf configuration not to throw erroneous error messages (e.g.
userconf.sh is expected to exit with 0, users explicitly declared, config file explicitly declared to avoid security vulnerability of custom conf in working dir, etc).
