Getting started

Initial configuration

By default debops.core is run from its own core.yml DebOps playbook by the common.yml playbook, which means that it is run on all hosts in the inventory.

If you want to modify the "root path" variables (core__root_*), it's best to prepare the new ones before initial configuration (for example in a test environment), so that you won't need to change them after everything is configured.

To see what facts are configured on a host, run command:

user@host:~$ ansible <hostname> -s -m setup -a 'filter=ansible_local'

Ansible Controller IP addresses

The debops.core role gathers information about the IP address(es) from which the Ansible Controller host is connecting from using the $SSH_CLIENT environment variable on the remote host.

The list of Ansible Controller IP addresses is accessible as ansible_local.core.ansible_controllers for other roles to use as needed.

Warning

For the IP address gathering to work correctly, you shouldn't specify become parameters in the Ansible inventory. In that case the playbook or task level setting won't be able to override the inventory setting and the IP address will be inaccessible to Ansible.

Example playbook

To get information about the IP address of the Ansible Controller, debops.core needs to be run from special playbook, which does not switch to privileged mode by default, but the role within it does. That way, the role has access to the environment variables of the unprivileged account Ansible is connecting through and can read the $SSH_CLIENT environment variable and get the IP address.

Note: Hosts provisioned by the debops.bootstrap role have a workaround in place so that the playbook could be run in privileged mode but to avoid problems with other provisioning methods the role should be run in unprivileged mode as mentioned.

This is a playbook that is used to run the role:

---

- name: Prepare core environment
  hosts: [ 'debops_all_hosts', 'debops_service_core' ]
  become: False

  environment: '{{ inventory__environment | d({})
                   | combine(inventory__group_environment | d({}))
                   | combine(inventory__host_environment  | d({})) }}'

  roles:

    - role: debops.core
      tags: [ 'role::core' ]
      become: True

If you use your own set of custom playbooks, you can either copy the above playbook, or, if you have the DebOps playbooks installed in the default location, include the core.yml playbook in your common playbook (it is sufficient to run it only once at the start of the playbook):

---

- include: ~/.local/share/debops/debops-playbooks/playbooks/core.yml

- name: Common playbook
  hosts: 'debops_all_hosts'
  become: True

  roles:

    - role: example-role

If you use the default DebOps playbooks alongside your own custom ones, you don't need to include the core.yml playbook at all.

See the usage guide in the debops.core documentation for information about its use.
