A live demo talk about Helm by Rob Richardson.

See the slides at https://robrich.org/slides/at-the-helm-of-kubernetes/#/

Run it

1. Install helm from https://github.com/helm/helm/releases and set helm in your path.

2. Build the docker image:

   cd src
   docker build -t atthehelm:v0.1.0 .
   cd ..
   

3. Run the template for the helm chart in the chart folder:

   helm template chart --set imageLabel=v0.1.0,ingressHost="",registry=""
   

   or start it directly in Kubernetes:

   helm template chart --set imageLabel=v0.1.0,ingressHost="",registry="" | kubectl apply -f -
   

4. Create a helm chart package:

   a. Install helm-pack plugin:

   helm plugin install https://github.com/thynquest/helm-pack.git
   

   b. Package the chart in the chart folder:

   helm pack chart --app-version 0.1.0 --version 0.1.0 --destination dist --set imageLabel=v0.1.0,registry="",ingressHost=""
   

5. Run the packaged chart:

   helm install my-app ./dist/atthehelm-0.1.0.tgz --set ingressEnabled=false,replicas=2
   

   then see what you created:

   helm list
   

6. Remove the chart:

   helm uninstall my-app
