• Bug in ansible playbook

Details: When I try to run the dockerhost.yml playbook I get a number of failures:

• check_mem download fails in Nagios_Plugins role - https://github.com/adoptium/infrastructure/issues/2810
• Nagios_Master_Config role fails The task includes an option with an undefined variable. The error was: 'provider is undefined'
• Nagios_Tunnel role fails trying to add the ssh key: 'ansible_port' is undefined (FYI @steelhead31)
• The DockerStatic role failes as it says ERROR! couldn't resolve module/action 'community.docker.docker_container. This may have been introduced by https://github.com/adoptium/infrastructure/pull/2544 (FYI @zdtsw @Willsparker @karianna)

did ERROR! couldn't resolve module/action 'community.docker.docker_container. happen on certain machine? which version of ansible is running there?

worth check whats in the $home/.ansible/collections/ansible_collections/ on that machine

It's on a 'clean' (new install) of Ubuntu 20.04 with ansible 2.9.6 installed via the package manager. There is no collections directory under ~/.ansible

[zdtsw]

so I think this newly installer machine need to have community plugins locally first. e.g if run ansible-galaxy collection install community.docker , it downloads into $home/.ansible/collections/ansible_collections/community/docker

then playbook will be able to find community.docker.docker_container
