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.

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.

2. Start Docker

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

Configure Ingestion

Once your server security is set, it’s time to review the ingestion configuration. Our bots support JWT tokens to authenticate to the server when sending requests. Find more information on Enabling JWT Tokens and JWT Troubleshooting to ensure seamless authentication.
