Add default varaibles about ansible-docker HOT 5 CLOSED

I can't say for sure but that sounds like maybe you ran the playbook without gathering facts.

You'll need to gather_facts: True for those ansible_* variables to be defined. This is normal Ansible behavior.

from ansible-docker.

You shouldn't need to configure anything extra to have everything work. Just by calling the role with its current defaults you should end up with the latest Docker / Docker Compose installed and a cron job to deal with Docker related maintenance.

What held you back from it all working automatically?

Btw all of the defaults in the readme are real defaults. You can see them at https://github.com/nickjj/ansible-docker/blob/master/defaults/main.yml.

from ansible-docker.

There are a couple of predefined variables but

TASK [nickjj.docker : Configure upstream APT repository] **************************************************************************************************************************** fatal: [default]: FAILED! => {"failed": true, "msg": "The task includes an option with an undefined variable. The error was: deb [arch=amd64] https://download.docker.com/linux/{{ docker_distribution | lower }} {{ docker_distribution_release }} {{ docker_channel }}: {{ ansible_local.core.distribution_release if (ansible_local|d() and ansible_local.core|d() and ansible_local.core.distribution_release|d()) else ansible_distribution_release }}: 'ansible_distribution_release' is undefined\n\nThe error appears to have been in '/Users/artem/.ansible/roles/nickjj.docker/tasks/main.yml': line 26, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Configure upstream APT repository\n ^ here\n\nexception type: <class 'ansible.errors.AnsibleUndefinedVariable'>\nexception: deb [arch=amd64] https://download.docker.com/linux/{{ docker_distribution | lower }} {{ docker_distribution_release }} {{ docker_channel }}: {{ ansible_local.core.distribution_release if (ansible_local|d() and ansible_local.core|d() and ansible_local.core.distribution_release|d()) else ansible_distribution_release }}: 'ansible_distribution_release' is undefined"}

as u can see there are a lot of not predefined variables
