+# ansible-role-coller
+
+Ansible role to manage a [coller](https://git.riou.xyz/jriou/coller) instance.
+
+## Installation
+
+Clone the repository in your local Ansible roles directory:
+
+```
+git clone https://git.riou.xyz/jriou/ansible-role-coller.git ~/.ansible/roles/coller
+```
+
+See [Storing and finding
+roles](https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_reuse_roles.html#storing-and-finding-roles).
+
+## Configuration
+
+See [Variable
+precedence](https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_variables.html#ansible-variable-precedence)
+to find where you should put your own variables.
+
+Then define at least `coller_db_password` with a strong and secure password,
+encrypted using
+[ansible-vault](https://docs.ansible.com/ansible/latest/cli/ansible-vault.html).
+
+See list of [default variables](defaults/main.yml).
+
+
+## Usage
+
+Example of a basic coller.yml playbook:
+
+```yaml
+- hosts: coller
+  roles:
+    - coller
+```
+
+Then run the playbook:
+
+```
+ansible-playbook coller.yml
+```
