Spring is a modern Java framework.
This chart is designed to be a general purpose chart for running Spring based applications.
Release name must be suffix by -stable or -canary
To add repo with the name stephane80000:
$ helm repo add stephane80000 https://stephane80000.github.io/helm-charts/
$ helm repo update
To install the chart with the release name myapp-stable and YAML files that specifies the values for the parameters values-xxx.yaml and secrets values-secret-xxx.yaml in the namespace mynamespace :
$ helm install myapp-stable stephane80000/spring --version X.X.X -n mynamespace -f values-xxx.yaml -f values-secret-xxx.yaml --set image.repository=de.icr.io/myimage,image.tag=0.0.2
To install the chart with the release name myapp-stable and a YAML file that specifies the values for the parameters values-xxx.yaml and secrets values-secret-xxx.yaml in the namespace mynamespace :
$ helm upgrade myapp-stable stephane80000/spring --version X.X.X -n mynamespace -f values-xxx.yaml -f values-secret-xxx.yaml --reuse-values
To uninstall/delete the myapp-stable deployment:
helm uninstall myapp-stable
The command removes nearly all the Kubernetes components associated with the chart and deletes the release.
The following table lists the configurable parameters and their default values.
Alternatively, you can sepcify each parameter using the --set key=value[,key=value] argument to helm install.
Tip: You can donwload the sample spring/values.yaml
