Re: [ansible-project] ansible --check mode for shift left

[Mike Eggleston]

Try a dry run with —check on a remote host (—limit $HOST). I forgot, —check 
does a dry run.

Hi Steve,

Take a look at check_mode and assess your playbook to see which features are 
you can safely change, ie those that do not make change.

[ansible-project] ansible --check mode for shift left

[Steve Button]

Hi,

I'm trying to add some "shift left" to my Ansible, so that mistakes don't 
creep in. Firstly, I thought I would run --check (perhaps as a git 
pre-commit hook or perhaps in Jenkins pipeline eventually). So, I tried it 
locally. Unfortunately it bombs out in several places, as some tasks are 
reliant on the output of other tasks. Not a great problem, as I've added 

when: not ansible_check_mode

to those tasks. 

Is there a better way of achieving this? Particularly it would be useful to 
check that variables are set to something sensible (catch typos or just 
missed variables) BEFORE it goes into production. We have vars files based 
on environments, so these don't get checked until we actually deploy to 
that environment.
