Updating the authentication service

1. Make sure that a newer version of authentication service exists in the Docker Registry. See On-Premise releases.

2. Update settings in the values-keycloak.yaml configuration file, if necessary. See the example in the installation instructions.

3. Run the command to update the service:

   helm upgrade --install --version=1.14.0 --atomic --values ./values-keycloak.yaml keycloak 2gis-on-premise/keycloak
