MQ can be accessed via port 1414 on the following DNS name from within your cluster:
{{ template "fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local

To get your admin password run:

    MQ_ADMIN_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "fullname" . }} -o jsonpath="{.data.adminPassword}" | base64 --decode; echo)

If you set an app password, you can retrieve it by running the following:

    MQ_APP_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "fullname" . }} -o jsonpath="{.data.appPassword}" | base64 --decode; echo)
