Chart¶

https://helm.sh/docs/topics/charts/

put a chart into a web repo¶

mv jupyterhub-0.1.0.tgz ./jupyterhub/charts/ #copy chart package to the charts folder
helm repo index ./jupyterhub/charts/ --url https://my.github.io/jupyterhub/charts/ #create index.yaml

helm repo index ... will create the index.yaml file inside the charts directory

create a helm chart and deploy it¶

https://learn.microsoft.com/en-us/azure/aks/quickstart-helm?tabs=azure-cli

helm create <chart-name>
cd <chart-name>
helm dependency update
# update values.yaml for image info etc.
helm install <release-name> .

# alternatively execute out of the folder
# helm install <release-name> <chart-name>/ --values <chart-name>/values.yaml

disable chart¶

in values.yaml add enabled: false. and then update deployment yaml files.

{{- if .Values.enabled }}
apiVersion: apps/v1
kind: Deployment
# ... rest of your deployment definition ...
{{- end }}

dependencies¶

https://helm.sh/docs/chart_best_practices/dependencies/#helm

local repository: Chart.yaml

dependencies:
  - name: mychart
    version: 3.1.1
    repository: file://.

The value of the repository should be the path to the folder in which there is a chart file called <name>-<version>.tgz. In the above example, the mychart-3.1.1.tgz file should be in the same folder for the Chart.yaml file.

If there is a charts folder within the same folder of Chart.yaml the repository should be repository: file://./charts/mychart - the mychart should be a folder containing all the unzipped chart files.

oci repository Store charts as OCI artifacts - only available in helm 3.
