Updating the authentication service

1. (Recommended) Back up data used by the service.

2. Fetch new installation artifacts.

   To get artifacts for the authentication service only, add --services=keycloak after the pull command. Without this parameter artifacts for all services will be fetched by default.

   See the reference of DGCLI command-line arguments.

3. Check out breaking changes. If necessary, update settings in the values-keycloak.yaml configuration file. For more information, see the service installation instructions.

4. Run the command to update the service:

   helm upgrade --install --version=1.21.0 --atomic --values ./values-keycloak.yaml keycloak 2gis-on-premise/keycloak
   

5. Test if the update succeeded.
