PostgreSQL can be accessed via port 5432 on the following DNS name from within your cluster:
|
|
{{ template "fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
|
|
|
|
To get your user password run:
|
|
|
|
PGPASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "fullname" . }} -o jsonpath="{.data.postgres-password}" | base64 --decode; echo)
|
|
|
|
To connect to your database run the following command (using the env variable from above):
|
|
|
|
kubectl run {{ template "fullname" . }}-client --rm --tty -i --image postgres \
|
|
--env "PGPASSWORD=$PGPASSWORD" \
|
|
--command -- psql -U {{ default "postgres" .Values.postgresUser }} \
|
|
-h {{ template "fullname" . }} {{ default "postgres" .Values.postgresDatabase }}
|
|
|
|
To connect to your database directly from outside the K8s cluster:
|
|
{{- if contains "NodePort" .Values.service.type }}
|
|
PGHOST=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath='{.items[0].status.addresses[0].address}')
|
|
PGPORT=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "fullname" . }} -o jsonpath='{.spec.ports[0].nodePort}')
|
|
|
|
{{- else if contains "ClusterIP" .Values.service.type }}
|
|
PGHOST=127.0.0.1
|
|
PGPORT={{ default "5432" .Values.service.port }}
|
|
|
|
# Execute the following commands to route the connection:
|
|
export POD_NAME=$(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "fullname" . }}" -o jsonpath="{.items[0].metadata.name}")
|
|
kubectl port-forward $POD_NAME {{ default "5432" .Values.service.port }}:{{ default "5432" .Values.service.port }}
|
|
|
|
{{- end }} |
