What is Helm

The package manager for KubernetesHelm is the best way to find, share, and use software built for Kubernetes.

Helm helps you manage Kubernetes applications —Helm Charts helps you define, install, and upgrade even the most complex Kubernetes application.Charts are easy to create, version, share, and publish — so start using Helm and stop the copy-and-paste madness.The latest version of Helm is maintained by the CNCF - in collaboration with Microsoft, Google, Bitnami and the Helm contributor community.

What is Draft

Streamlined Kubernetes DevelopmentSimple app development & deployment - into any Kubernetes cluster.

Draft makes it easy to build applications that run on Kubernetes. Draft targets the "inner loop" of a developer's workflow: as they hack on code, but before code is committed to version control.

I’m basically just going to do live demos for the rest of this presentation…

Do we have a working Kube Cluster?

kubectl version

helm version

helm init --upgrade

Deploy someone else's Helm Chart

helm install stable/nginx-ingress

helm install -f values.yaml stable/jenkins

Build my own Chart~$ helm create mychart

~$ cat mychart/values.yaml
