MOLGENIS Helm templates

These are the Helm templates that we will use for MOLGENIS operations. There are some prerequisites you need.

  • docker
  • minikube

Useful commands for Kubernetes

Commands that can be used to get information from a kubernetes cluster

  • kubectl get pods Gets alls running instances of containers from a certain deployment
  • kubectl get services Gets all services from a deployment
  • kubectl get pv Gets all persistant volumes
  • kubectl get pvc Gets all persistent volume claims
  • kubectl get deployments Gets all deployments (comparable with docker-compose)

When you want to see what is running on the clusters at the CIT you have to make a context switch. You can access the cluster with kubeconfig-files. You can obtain these by downloading them from the MOLGENIS kubernetes cluster.

Useful commands for Helm

  • helm install . Do it in the root of the project where the Chart.yaml is located It installs a release of a kubernetes stack. You also store this as an artifact in a kubernetes repository
  • helm list Lists all installed releases
  • helm delete #release# Performs a sort of mvn clean on your workspace. Very handy for zombie persistent volumes or claims.
