Thank you for installing {{ .Chart.Name }}.
Your release is named {{ .Release.Name }}.
To learn more about the release, try:
$ helm status {{ .Release.Name }} -n {{ .Release.Namespace }}
$ helm get all {{ .Release.Name }} -n {{ .Release.Namespace }}
KubeMirror is now running and will automatically mirror resources across namespaces.
To mirror a Secret or ConfigMap, add this LABEL and ANNOTATIONS:
# Label (required for server-side filtering):
kubemirror.raczylo.com/enabled: "true"
# Annotations:
kubemirror.raczylo.com/sync: "true"
kubemirror.raczylo.com/target-namespaces: "namespace1,namespace2"
Or use "all" to mirror to all namespaces with the allow-mirrors label:
kubemirror.raczylo.com/target-namespaces: "all"
To allow a namespace to receive mirrored resources, add this label:
kubemirror.raczylo.com/allow-mirrors: "true"
View controller logs:
$ kubectl logs -n {{ .Release.Namespace }} -l app.kubernetes.io/name={{ include "kubemirror.name" . }}
Check metrics:
$ kubectl port-forward -n {{ .Release.Namespace }} svc/{{ include "kubemirror.fullname" . }}-metrics {{ .Values.service.metricsPort }}:{{ .Values.service.metricsPort }}
$ curl http://localhost:{{ .Values.service.metricsPort }}/metrics
