# Ansible Collection - middleware_automation.keycloak

[![Build Status](https://github.com/ansible-middleware/keycloak/workflows/CI/badge.svg?branch=main)](https://github.com/ansible-middleware/keycloak/actions/workflows/ci.yml)


Collection to install and configure [Keycloak](https://www.keycloak.org/) or [Red Hat Single Sign-On](https://access.redhat.com/products/red-hat-single-sign-on). 

<!--start requires_ansible-->
## Ansible version compatibility

This collection has been tested against following Ansible versions: **>=2.9.10**.

Plugins and modules within a collection may be tested with only specific Ansible versions. A collection may contain metadata that identifies these versions.
<!--end requires_ansible-->


## Installation

### Installing the Collection from Ansible Galaxy

Before using the collection, you need to install it with the Ansible Galaxy CLI:

    ansible-galaxy collection install middleware_automation.keycloak

You can also include it in a `requirements.yml` file and install it via `ansible-galaxy collection install -r requirements.yml`, using the format:

```yaml
---
collections:
  - name: middleware_automation.keycloak
```

The keycloak collection also depends on the following python packages to be present on the controller host:

* netaddr

A requirement file is provided to install:

    pip install -r requirements.txt


### Included roles

* [`keycloak`](https://github.com/ansible-middleware/keycloak/blob/main/roles/keycloak/README.md): role for installing the service.
* [`keycloak_realm`](https://github.com/ansible-middleware/keycloak/blob/main/roles/keycloak_realm/README.md): role for configuring a realm, user federation(s), clients and users, in an installed service.
* [`keycloak_quarkus`](https://github.com/ansible-middleware/keycloak/blob/main/roles/keycloak_quarkus/README.md): role for installing the quarkus variant of keycloak (>= 17.0.0).


## Usage


### Install Playbook

* [`playbooks/keycloak.yml`](https://github.com/ansible-middleware/keycloak/blob/main/playbooks/keycloak.yml) installs the upstream(Keycloak) based on the defined variables.
* [`playbooks/rhsso.yml`](https://github.com/ansible-middleware/keycloak/blob/main/playbooks/rhsso.yml) installs Red Hat Single Sign-On(RHSSO) based on defined variables.

Both playbooks include the `keycloak` role, with different settings, as described in the following sections.

For full service configuration details, refer to the [keycloak role README](https://github.com/ansible-middleware/keycloak/blob/main/roles/keycloak/README.md).


#### Install from controller node (local source)

Making the keycloak zip archive (or the RHSSO zip archive), available to the playbook repository root directory, and setting `keycloak_offline_install` to `True`, allows to skip
the download tasks. The local path for the archive matches the downloaded archive path, so it is also used as a cache when multiple hosts are provisioned in a cluster.

```yaml
keycloak_offline_install: True
```

And depending on `keycloak_rhsso_enable`:

* `True`: install RHSSO using file rh-sso-x.y.z-server-dist.zip
* `False`: install keycloak using file keycloak-x.y.zip


#### Install from alternate sources (like corporate Nexus, artifactory, proxy, etc)

For RHSSO:

```yaml
sso_download_url: "https://<internal-nexus.private.net>/<path>/<to>/rh-sso-x.y.z-server-dist.zip"
```

For keycloak:

```yaml
keycloak_download_url: "https://<internal-nexus.private.net>/<path>/<to>/keycloak-x.y.zip"
```


### Example installation command

Execute the following command from the source root directory 

```
ansible-playbook -i <ansible_hosts> -e @rhn-creds.yml playbooks/keycloak.yml -e keycloak_admin_password=<changeme>
``` 

- `keycloak_admin_password` Password for the administration console user account.
- `ansible_hosts` is the inventory, below is an example inventory for deploying to localhost

  ```
  [keycloak]
  localhost ansible_connection=local
  ```
