PostgreSQL can be accessed via port {{ template "postgresql.port" . }} on the following DNS name from within your cluster:
|
||
|
|
|
||
|
|
{{ template "postgresql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local - Read/Write connection
|
||
|
|
{{- if .Values.replication.enabled }}
|
||
|
|
{{ template "postgresql.fullname" . }}-read.{{ .Release.Namespace }}.svc.cluster.local - Read only connection
|
||
|
|
{{- end }}
|
||
|
|
|
||
|
|
{{- if and (not (eq .Values.postgresqlUsername "postgres")) (or .Values.postgresqlPostgresPassword (include "postgresql.useExistingSecret" .)) }}
|
||
|
|
|
||
|
|
To get the password for "postgres" run:
|
||
|
|
|
||
|
|
export POSTGRES_ADMIN_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "postgresql.secretName" . }} -o jsonpath="{.data.postgresql-postgres-password}" | base64 --decode)
|
||
|
|
{{- end }}
|
||
|
|
|
||
|
|
To get the password for "{{ template "postgresql.username" . }}" run:
|
||
|
|
|
||
|
|
export POSTGRES_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "postgresql.secretName" . }} -o jsonpath="{.data.postgresql-password}" | base64 --decode)
|
||
|
|
|
||
|
|
To connect to your database run the following command:
|
||
|
|
|
||
|
|
kubectl run {{ template "postgresql.fullname" . }}-client --rm --tty -i --restart='Never' --namespace {{ .Release.Namespace }} --image {{ template "postgresql.image" . }} --env="PGPASSWORD=$POSTGRES_PASSWORD" {{- if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
|
||
|
|
--labels="{{ template "postgresql.fullname" . }}-client=true" {{- end }} --command -- psql --host {{ template "postgresql.fullname" . }} -U {{ .Values.postgresqlUsername }} -d {{- if .Values.postgresqlDatabase }} {{ .Values.postgresqlDatabase }}{{- else }} postgres{{- end }} -p {{ template "postgresql.port" . }}
|
||
|
|
|
||
|
|
{{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
|
||
|
|
Note: Since NetworkPolicy is enabled, only pods with label {{ template "postgresql.fullname" . }}-client=true" will be able to connect to this PostgreSQL cluster.
|
||
|
|
{{- end }}
|
||
|
|
|
||
|
|
To connect to your database from outside the cluster execute the following commands:
|
||
|
|
|
||
|
|
{{- if contains "NodePort" .Values.service.type }}
|
||
|
|
|
||
|
|
export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
|
||
|
|
export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "postgresql.fullname" . }})
|
||
|
|
{{ if (include "postgresql.password" . ) }}PGPASSWORD="$POSTGRES_PASSWORD" {{ end }}psql --host $NODE_IP --port $NODE_PORT -U {{ .Values.postgresqlUsername }} -d {{- if .Values.postgresqlDatabase }} {{ .Values.postgresqlDatabase }}{{- else }} postgres{{- end }}
|
||
|
|
|
||
|
|
{{- else if contains "LoadBalancer" .Values.service.type }}
|
||
|
|
|
||
|
|
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
|
||
|
|
Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "postgresql.fullname" . }}'
|
||
|
|
|
||
|
|
export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "postgresql.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")
|
||
|
|
{{ if (include "postgresql.password" . ) }}PGPASSWORD="$POSTGRES_PASSWORD" {{ end }}psql --host $SERVICE_IP --port {{ template "postgresql.port" . }} -U {{ .Values.postgresqlUsername }} -d {{- if .Values.postgresqlDatabase }} {{ .Values.postgresqlDatabase }}{{- else }} postgres{{- end }}
|
||
|
|
|
||
|
|
{{- else if contains "ClusterIP" .Values.service.type }}
|
||
|
|
|

|
