Sample crontab entry..

#Ansible: Container housekeeping
30 2 * * * /usr/local/bin/housekeep_docker.sh check >> /var/log/docker_housekeeping.log 2>&1

[steelhead31]

When run with the following:

ansible-playbook -i hosts AdoptOpenJDK_Unix_Playbook/main.yml --extra-vars "script_action=delete"

Crontab entry appears as follows:

#Ansible: Container housekeeping
30 2 * * * /usr/local/bin/housekeep_docker.sh delete >> /var/log/docker_housekeeping.log 2>&1

I'll probably come back and have another more detailed read through this but this looks good overall.
Also bonus points for writing the script for sh and not bash ;-)

I had issues with bash on one of my vagrant boxes ( though I don't recall which one.. ) also lucky it didn't end up in ksh! 😆
