Getting started

Default configuration

The role will detect presence of a MariaDB database server and use it if available. If not, a SQLite database will be automatically configured on the server. You can configure MariaDB database using the debops.mariadb_server Ansible role.

Example inventory

To install and configure Etherpad on a host, it needs to be present in the [debops_service_etherpad] Ansible inventory group:

[debops_service_etherpad]
hostname

Example playbook

If you are using this role without DebOps, here's an example Ansible playbook that uses the debops.etherpad role:

---

- name: Manage Etherpad service
  collections: [ 'debops.debops', 'debops.roles01',
                 'debops.roles02', 'debops.roles03' ]
  hosts: [ 'debops_service_etherpad' ]
  become: True

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

  roles:

Ansible tags

You can use Ansible --tags or --skip-tags parameters to limit what tasks are performed during Ansible run. This can be used after a host was first configured to speed up playbook execution, when you are sure that most of the configuration is already in the desired state.

Available role tags:

role::etherpad

Main role tag, should be used in the playbook to execute all of the role tasks as well as role dependencies.

role::etherpad:source

Run tasks related to install Etherpad from source.

role::etherpad:config

Run tasks related to configuring Etherpad.

role::etherpad:plugins

Run tasks which install the defined Etherpad plugins.

role::etherpad:api:call

Run tasks API call tasks. Can be used for rapid API calls.

role::etherpad:api

Same as role::etherpad:api:call but ensures that the service is running and waiting for it to start before trying.
