Different path for two users added in Docker group

Solution 1:

It appears that your saeed account is configured to run docker in the rootless configuration. That means you're talking to a separate docker daemon running as your user, storing files in your users home directory. There's no need to add your user to the docker group for this, and doing so would defeat the security gained by running a rootless daemon (since that same user could reconfigure their DOCKER_HOST variable to talk to the daemon running as root, escalating their privileges).

The test1 user is using the traditional docker install running a single daemon as root. You'll likely see better performance and fewer issues doing this, but ensure that you trust the user running commands as the root user on the host.
