# Keycloak SSO for Docker

To enable security for the Docker deployment, follow the next steps:

## 1. Create an .env file

Create an `openmetadata_keycloak.env` file and add the following contents as an example. Use the information
generated when setting up the account.



Check the more information about environment variable [here](/deployment/security/configuration-parameters).

{% note %}

Altering the order of claims in `jwtPrincipalClaims` may lead to problems when matching a user from a token with an existing user in the system. The mapping process relies on the specific order of claims, so changing it can result in inconsistencies or authentication failures, as the system cannot ensure correct user mapping with a new claim order.

{% /note %}

## 2. Start Docker

```commandline
docker compose --env-file ~/openmetadata_keycloak.env up -d
```
