Helm Example

This example demonstrates how a Helm chart can be included as an artifact within a CSAR.

Building the CSAR

• Package the Helm chart
• Package as CSAR file

Deploying

turandot service deploy helm-hello-world --file=dist/helm-hello-world.csar

Note that though Helm is used to create the Kubernetes manifests, Turandot is controlling them. The helm command line tool will not be able to list the release. Use the turandot service command instead.

How the Helm Chart Was Created

We used helm create hello-world. Unfortunately, this example chart assumes privileged permissions on the host that are not allowed out-of-the-box on OpenShift. To ensure it would work on OpenShift we made two changes:

• In value.yaml we changed image.repository to bitnami/nginx, which is a containerization of NGINX that does not require priveleged permissions (documentation).
• In templates/deployment.yaml we changed the port from 80 to 8080 (port 80 requires privileged permissions).
