Ansible role to deploy postgresql software with replication
|GitHub|Version|Issues|Pull Requests|Downloads|

|[](https://github.com/buluma/ansible-role-postgresql_replication/actions/workflows/molecule.yml)|[](https://github.com/buluma/ansible-role-postgresql_replication/releases/)|[](https://github.com/buluma/ansible-role-postgresql_replication/issues/)|[](https://github.com/buluma/ansible-role-postgresql_replication/pulls/)|[](https://galaxy.ansible.com/ui/standalone/roles/buluma/postgresql_replication/documentation)|
## [Example Playbook](#example-playbook)
This example is taken from [`molecule/default/converge.yml`](https://github.com/buluma/ansible-role-postgresql_replication/blob/master/molecule/default/converge.yml) and is tested on each push, pull request and release.
```yaml
---
- name: Converge
hosts: all
become: yes
gather_facts: yes
roles:
- role: buluma.postgresql_replication
```
The machine needs to be prepared. In CI this is done using [`molecule/default/prepare.yml`](https://github.com/buluma/ansible-role-postgresql_replication/blob/master/molecule/default/prepare.yml):
```yaml
---
- name: Prepare
hosts: all
become: yes
gather_facts: no
roles:
- role: buluma.bootstrap
# - role: buluma.postgresql
- role: enix.postgresql
```
Also see a [full explanation and example](https://buluma.github.io/how-to-use-these-roles.html) on how to use these roles.
## [Role Variables](#role-variables)
The default values for the variables are set in [`defaults/main.yml`](https://github.com/buluma/ansible-role-postgresql_replication/blob/master/defaults/main.yml):
```yaml
---
# defaults file for postgresql_replication
postgresql_replication__group: "postgresql"
postgresql_replication__group_master: "postgresql_master"
postgresql_replication__group_replicas: "postgresql_replicas"
postgresql_replication__user: "replicate"
postgresql_replication__password: "replicate"
postgresql_replication__waldir: "/var/lib/postgresql/wal-slave/"
postgresql_replication__walsenders: 3
postgresql_replication__walsegments: 64
# !!! set this to 'yesiwant' to bootstrap cluster
# postgresql_replication__bootstrap undefined
postgresql_replication__trigger_file: "/tmp/MasterNow"
```
