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.
