A Helm chart for Kubernetes
helm repo add christianknell https://christianknell.github.io/helm-charts
helm repo update
helm install my-release christianknell/proxywebThis chart bootstraps a ProxyWeb deployment on a Kubernetes cluster using the Helm package manager.
- Kubernetes 1.19+
To install the chart with the release name my-release:
helm repo add christianknell https://christianknell.github.io/helm-charts
helm repo update
helm install my-release christianknell/proxywebThese commands deploy ProxyWeb on the Kubernetes cluster in the default configuration. The Values section lists the values that can be configured during installation.
Tip: List all releases using
helm list
To uninstall the my-release deployment:
helm uninstall my-releaseThe command removes all the Kubernetes components associated with the chart and deletes the release.

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 my-release -f values.yaml christianknell/proxywebAutogenerated from chart metadata using helm-docs v1.11.0
