I've opened an issue at Ansible GitHub and got explained how argv parameter
works.
https://github.com/ansible/ansible/issues/79967
Summary:
This happens because of how module and redis-cli utility work with
arguments.
When passing arguments this modules delimits them with single quotation
marks, so
- name: Create Redis cluster
ansible.builtin.command:
argv:
- /usr/bin/redis-cli
- "--user {{ redis_admin_user }}"
- "--pass {{ redis_admin_password }}"
- "--cluster create {{ redis_cluster_members }}"
- "--cluster-replicas {{ redis_cluster_replicas }}"
- --cluster-yes
is passed as (mind the quotation marks)
/usr/bin/redis-cli '--user admin' '--pass mypass' '--cluster create
10.226.2.194:6379 10.226.2.196:6379 10.226.2.195:6379' '--cluster-replicas
1' '--cluster-yes'
If you enter this command directly into command line you'll get the same
error - "Unrecognized option or bad number of args for: '--user admin'".
This is because, quoting redis-cli documentation
(https://redis.io/docs/ui/cli/#string-quoting-and-escaping),
> When redis-cli parses a command, whitespace characters automatically
delimit the arguments.
So the correct way to pass this command will be (mind the quotation marks)
/usr/bin/redis-cli '--user' 'admin' '--pass' 'mypass' '--cluster' 'create '
'10.226.2.194:6379' '10.226.2.196:6379' '10.226.2.195:6379'
'--cluster-replicas' '1' '--cluster-yes'
So I did a workaround constructing the command as a variable in
vars/main.yml and then passing it to the module (I'm going to post it on
stackoverflow).
