Spring is a modern Java framework for developing Cloud Native Applications.
This chart is designed to be a general purpose chart for running Spring based applications, most simple Spring applications should run with little to no modification of this Chart. For the sake of example this chart is configured to deploy the Spring Petclinic example application, but simply changing the image and tag should be enough to run a different app.
To install the chart with the release name my-release:
$ helm install --name my-release stable/springTo uninstall/delete the my-release deployment:
helm delete --purge my-releaseThe command removes nearly all the Kubernetes components associated with the chart and deletes the release.
The following table lists the configurable parameters of the drone charts and their default values.
Specify each parameter using the --set key=value[,key=value] argument to helm install.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
helm install --name my-release -f values.yaml stable/springTip: You can use the default values.yaml
