Missing write permissions for "docker" home directory

[mbrodala]

Expected Behavior

Commands can write to the home directory of docker (~, /home/docker), e.g. ~/.cache.

Current Behavior

There are permission errors, .e.g in Yarn:

yarn run v1.22.5
warning Skipping preferred cache folder "/home/docker/.cache/yarn" because it is not writable.
warning Selected the next writable cache folder in the list, will be "/tmp/.yarn-cache-1001".

Possible Solution

Update the owner ID of /home/docker in the image entrypoint.

Steps to Reproduce (for bugs)

1. Have a host user with an ID different from 1000
2. Start a container, e.g. PHP-FPM
3. Run a command or interactive shell
4. Try to write to /home/docker

Context

I noticed this with a Yarn installation.

The owner of /home/docker is left at 1000:

$ ls -ld ~
drwxr-xr-x 1 1000 docker 4096 Apr 11 06:00 /home/docker

However, the ID of the docker user was updated to reflect my host user:

$ id
uid=1001(docker) gid=1000(docker) groups=1000(docker),27(sudo)
