Spring Chart

Spring is a modern Java framework for developing Cloud Native Applications.

Chart Details

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.

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/spring

Uninstalling the Chart

To uninstall/delete the my-release deployment:

helm delete --purge my-release

The command removes nearly all the Kubernetes components associated with the chart and deletes the release.

Configuration

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/spring

Tip: You can use the default values.yaml
