4. Upgrade BinderHub

If there are any modifications to the Helm chart, remember to update the on-disk dependencies:

helm dependency update ./helm

Then apply it using helm upgrade:

helm upgrade --cleanup-on-fail \
    --install binderhub ./helm \
    --namespace=binderhub \
    --create-namespace \
    -f ./helm/prod.yaml \
    -f ./helm/secure.yaml \
    -f ./helm/secrets/secret.yaml
