PoC: add helm chart to install kiali-operator (#93)
* Add helm chart Signed-off-by: Jake Hill <[email protected]> * complete the helm chart work * Do not install istio-specific resources. There are too many ways users may want to customize the Gateway/VirtualService/DestinationRule. And since those configs involves Kiali Server config, not Operator, we do not want to create a bunch of customized values for this stuff. This helm chart should concentrate on installing only the Operator (with at most being able to install a Kiali CR but allowing the user to provide their own cr.spec since Kiali Server itself can be highly customizable).

| Welcome to Kiali! For more details on Kiali, see: https://kiali.io | ||
|
|
||
| The Kiali Operator [{{ .Chart.AppVersion }}] has been installed in namespace [{{ .Release.Namespace }}]. It will be ready soon. | ||
|
|
||
| {{- if .Values.cr.create }} | ||
| {{- if or (and (not .Values.watchNamespace) (not .Values.cr.namespace)) (and (.Values.watchNamespace) (eq .Values.watchNamespace .Release.Namespace)) (and (.Values.cr.namespace) (eq .Values.cr.namespace .Release.Namespace)) }} | ||
| You have elected to install a Kiali CR in the same namespace as the operator [{{ .Release.Namespace }}]. You should be able to access Kiali soon. | ||
|
|
||
| ================================ | ||
| PLEASE READ THIS WARNING NOTICE: | ||
| Because the Kiali CR lives in the same namespace as the operator, DO NOT uninstall the operator or delete the operator namespace without first removing the Kiali CR. If you do not follow this advice then the Kiali Operator deletion will hang indefinitely until you remove the finalizer from the Kiali CR, and then you may find your Kubernetes environment still has Kiali Server remnants left behind. | ||
| ================================ | ||
| {{- else if .Values.watchNamespace }} | ||
| You have elected to install a Kiali CR in the operator watch namespace [{{ .Values.watchNamespace }}]. You should be able to access Kiali soon. | ||
| {{- else if .Values.cr.namespace }} | ||
| You have elected to install a Kiali CR in the namespace [{{ .Values.cr.namespace }}]. You should be able to access Kiali soon. | ||
| {{- else }} | ||
| You have elected to install a Kiali CR. You should be able to access Kiali soon. | ||
| {{- end }} | ||
| {{- else }} | ||
| {{- if (not .Values.watchNamespace) }} | ||
| You have elected not to install a Kiali CR. You must first install a Kiali CR before you can access Kiali. The operator is watching all namespaces, so you can create the Kiali CR anywhere. | ||
| {{- else }} | ||
| You have elected not to install a Kiali CR. You must first install a Kiali CR in the operator watch namespace [{{ .Values.watchNamespace }}] before you can access Kiali. | ||
| {{- end }} | ||
| {{- end }} | ||
|
|
||
| If you ever want to uninstall the Kiali Operator, remember to delete the Kiali CR first before uninstalling the operator to give the operator a chance to uninstall and remove all the Kiali Server resources. | ||
