# Deploy and Configure Keycloak for Docs

## Installation

> \[!CAUTION\]
> We provide those instructions as an example, for production environments, you should follow the [official documentation](https://www.keycloak.org/documentation).

### Step 1: Prepare your working environment:

```bash
mkdir keycloak
curl -o compose.yaml https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/docs/examples/compose/keycloak/compose.yaml
curl -o env.d/kc_postgresql https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/env.d/production.dist/kc_postgresql
curl -o env.d/keycloak https://raw.githubusercontent.com/suitenumerique/docs/refs/heads/main/env.d/production.dist/keycloak
```

### Step 2:. Update `env.d/` files

The following variables need to be updated with your own values, others can be left as is:

```env
POSTGRES_PASSWORD=<generate postgres password>
KC_HOSTNAME=https://id.yourdomain.tld # Change with your own URL
KC_BOOTSTRAP_ADMIN_PASSWORD=<generate your password>
```

### Step 3: Expose keycloak instance on https

> \[!NOTE\]
> You can skip this section if you already have your own setup.

To access your Keycloak instance on the public network, it needs to be exposed on a domain with SSL termination. You can use our [example with nginx proxy and Let's Encrypt companion](../nginx-proxy/README.md) for automated creation/renewal of certificates using [acme.sh](http://acme.sh).

If following our example, uncomment the environment and network sections in compose file and update it with your values.

```yaml
version: '3'
services:
  keycloak:
   ...
    # Uncomment and set your values if using our nginx proxy example
    # environment:
    # - VIRTUAL_HOST=id.yourdomain.tld # used by nginx proxy 
    # - VIRTUAL_PORT=8080 # used by nginx proxy
    # - LETSENCRYPT_HOST=id.yourdomain.tld # used by lets encrypt to generate TLS certificate
   ...
# Uncomment if using our nginx proxy example
#    networks:
#    - proxy-tier
#    - default

# Uncomment if using our nginx proxy example
#networks:
#  proxy-tier:
#    external: true
```

### Step 4: Start the service

```bash
`docker compose up -d`
```

Your keycloak instance is now available on https://doc.yourdomain.tld
