helm

Helm is a tool for managing Kubernetes charts. Charts are packages of pre-configured Kubernetes resources.

Install From Binary Releases

• Download your desired version
• Unpack it (tar -zxvf helm-v2.0.0-linux-amd64.tgz)
• Find the helm binary in the unpacked directory, and move it to its desired destination (mv linux-amd64/helm /usr/local/bin/helm)

Install helm on Linux

curl -L https://git.io/get_helm.sh | bash

Install helm on macOS

brew install kubernetes-helm

Install From Chocolatey (Windows)

choco install kubernetes-helm

choco installation

After helm installed, run 'helm init' command to start work with helm.

If you get any permission denied errors while deploying applications through helm charts, run the following commands:

kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
