Greeting!
Asked it on stackoverflow
<https://stackoverflow.com/questions/75388765/how-can-i-pass-variables-to-command-modules-argv-parameter-in-ansible>,
but didn't get an answer, so I'm trying my luck here.
A bit condensed version:
I'm trying to write a role that creates a Redis cluster. At some point I
must execute redis-cli binary with some parameters:
/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
I pass all the required parameters as extra variables when I call the
playbook with a shell script:
#!/bin/sh ansible-playbook /etc/ansible/playbook-redis.yml -vv \
--extra-vars='redis_admin_user=admin redis_admin_password=mypass' \
--extra-vars='redis_cluster_members="10.226.2.194:6379 10.226.2.196:6379
10.226.2.195:6379" redis_cluster_replicas=1'
At first I tried the following:
- 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
And got error "Unrecognized option or bad number of args for: '--user
admin'" which is a redis-cli error.
After some experimenting I found out that if I pass the variables in a
separate line some of them work. So this task works and returns info about
server.
- name: Get server info
ansible.builtin.command:
argv:
- /usr/bin/redis-cli
- --user
- "{{ redis_admin_user }}"
- --pass
- "{{ redis_admin_password }}"
- info
So the username and password are recognized be redis-cli, but,
unfortunately not the "redis_cluster_members". The following task:
- 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
returns error "Unrecognized option or bad number of args for: '--cluster
create'"
I wonder if I'm missing some syntax error or misread the documentation and
trying to use argv not the way it's supposed to be used?
