Short tip: Utilize Ansible role via Vagrant
When implementing larger tasks in Ansible, you might thinking about writing your own Ansible role sooner or later. For this, the ansible-galaxy command can help you:
1$ ansible-galaxy init my-role
2- my-role was created successfully
Beside handlers, variables and meta data, also a test task is created. Using this task, the role can easily be assigned to a host:
1$ cat my-role/tests/test.yml
2---
3- hosts: localhost
4 remote_user: root
5 roles:
6 - my-role
This task can be linked within Vagrant to configure a freshly deployed system:
1config.vm.provision "ansible_local" do |ansible|
2 ansible.install_mode = "default"
3 ansible.playbook = "my-role/tests/test.yml"
4end
If you execute Vagrant now, it is very likely that Ansible won't find matching hosts:
1$ vagrant up
2...
3PLAY [localhost] ***************************************************************
4skipping: no hosts matched
5
6PLAY RECAP *********************************************************************
To fix this, simply replace localhost with all in the test task:
1$ sed -i "s/localhost/all/g" my-role/tests/test.yml
Afterwards, configuration succeeds:
1$ vagrant up --provision
2...
3PLAY [all] *********************************************************************
