geerlingguy.docker error during ansible installation

Although the installation seems to succeed and everything seems to work, we get the following error when installing v22.05 using ansible.

PLAY RECAP *********************************************************************
galaxy.classe.cornell.edu : ok=111 changed=8 unreachable=0 failed=1 skipped=50 rescued=0 ignored=0

Our python version is 3.8.11, and in group_vars/galaxyservers.yml we have:

docker_users:

  • “{{ galaxy_user.name }}”

Where galaxy_user.name is galaxy. Our galaxy user is in our central AD domain, and is in the docker group:
(venv) [galaxy@lnx229 ansible]$ id
uid=31292(galaxy) gid=6023(galaxy) groups=6023(galaxy),1500(docker)

Any help or suggestions would be greatly appreciated.

Many thanks,
Devin
