Helm In Docker

Package, install and upgrade helm charts with docker!

The dipsas/helm image includes helm and kubectl binaries, and makes it possible to package, install and upgrade helm charts inside of a container. In addition, it is built on top of the python docker image, so that it is possible to execute a python script instead of a shell script.

Example

$PWD is your full present working directory path.

Package chart:

docker run -it -v $PWD/charts/:/charts -w /charts dipsas/helm helm package my-helm-chart

Hint: Push a chart with DockerFeed.

Check kubectl config

docker run -it -v $PWD/charts/:/charts -w /charts dipsas/helm kubectl config view

Install chart in docker-desktop kubernetes

Change kubectl config in ./charts/.kube/config with your own kube config. Usually you can find your personal kube config with docker desktop on windows at:

• C:\Users\my-user\.kube\config

docker run -it -v $PWD/charts/:/charts -w /charts dipsas/helm helm install my-helm-chart ./my-helm-chart

Install charts in docker-desktop kubernetes with a shell script

Change kubectl config in ./charts/.kube/config with your own kube config. Usually you can find your personal kube config with docker desktop on windows at:

• C:\Users\my-user\.kube\config

Note! It is possible to execute a python script instead if a shell script.

docker run -it -v $PWD/charts/:/charts -w /charts dipsas/helm ./install.sh
docker run -it -v $PWD/charts/:/charts -w /charts dipsas/helm ./upgrade.sh
docker run -it -v $PWD/charts/:/charts -w /charts dipsas/helm ./uninstall.sh

The nginx in ./charts/my-helm-chart will be reachable on:

• https://my-helm-chart.localhost
