Set-up: Install helm:

• Download from https://storage.googleapis.com/kubernetes-helm/helm-v2.11.0-darwin-amd64.tar.gz
• mv helm /usr/local/bin
• helm init --client-only

From parent folder, execute helm template permissions-service to render the template, you'll notice it fails because some fields are required, so try helm template permissions-service -f env-config/dev-permissions-values.yaml --set database.read.user=a,database.write.user=b,database.read.password=c,database.write.password=d

Now render the umbrella chart helm template permissions-service-umbrella -f env-config/dev-permissions-umbrella-values.yaml

Another way of expressing a dependencies is rather than using a pure umbrella chart, like above, your chart can have a conditional requirement. Look at permissions-service-2/requirements.yaml acl is only included if 'deployAcl' is true
