** Please be patient while the chart is being deployed **
|
|
|
|
{{- if .Values.diagnosticMode.enabled }}
|
|
The chart has been deployed in diagnostic mode. All probes have been disabled and the command has been overwritten with:
|
|
|
|
command: {{- include "common.tplvalues.render" (dict "value" .Values.diagnosticMode.command "context" .) | nindent 4 }}
|
|
args: {{- include "common.tplvalues.render" (dict "value" .Values.diagnosticMode.args "context" .) | nindent 4 }}
|
|
|
|
Get the list of pods by executing:
|
|
|
|
kubectl get pods --namespace {{ $releaseNamespace }} -l app.kubernetes.io/instance={{ .Release.Name }}
|
|
|
|
Access the pod you want to debug by executing
|
|
|
|
kubectl exec --namespace {{ $releaseNamespace }} -ti <NAME OF THE POD> -- bash
|
|
|
|
In order to replicate the container startup scripts, check the /opt/bitnami/scripts folder.
|
|
|
|
Default PostgreSQL startup command
|
|
|
|
/opt/bitnami/scripts/postgresql-repmgr/entrypoint.sh /opt/bitnami/scripts/postgresql-repmgr/run.sh
|
|
|
|
Default Pgpool-II startup command
|
|
|
|
/opt/bitnami/scripts/pgpool/entrypoint.sh /opt/bitnami/scripts/pgpool/run.sh
|
|
|
|
{{- else }}
|
|
PostgreSQL can be accessed through Pgpool-II via port {{ .Values.service.ports.postgresql }} on the following DNS name from within your cluster:
|
|
|
|
{{ $pgpoolSvcName }}.{{ $releaseNamespace }}.svc.{{ $clusterDomain }}
|
|
|
|
Pgpool-II acts as a load balancer for PostgreSQL and forward read/write connections to the primary node while read-only connections are forwarded to standby nodes.
|
|
|
|
To get the password for {{ $postgresqlUsername | quote }} user run:
|
|
|
|
{{ include "common.utils.secret.getvalue" (dict "secret" $postgresqlSecretName "field" "password" "context" $) }}
|
|
|
|
To connect to your database run the following command:
|
|
|
|
kubectl run {{ include "common.names.fullname" . }}-client --rm --tty -i --restart='Never' --namespace {{ $releaseNamespace }} \
|
|
--image {{ include "postgresql-ha.postgresql.image" . }} --env="PGPASSWORD=$PASSWORD" {{ if and (.Values.pgpool.networkPolicy.enabled) (not .Values.pgpool.networkPolicy.allowExternal) }}--labels="{{ include "common.names.fullname" . }}-client=true" {{- end }} \
|
|
--command -- psql -h {{ $pgpoolSvcName }} -p {{ .Values.service.ports.postgresql }} {{ $postgresqlCredentials }}
|
|
|
|
{{- if and .Values.pgpool.networkPolicy.enabled (not .Values.pgpool.networkPolicy.allowExternal) }}
|
|
|
|
Note: Since NetworkPolicy is enabled, only pods with label "{{ $pgpoolSvcName }}-client=true" will be able to connect Pgpool-II.
|
|
|
|
{{- end }}
|
|
|
|
To connect to your database from outside the cluster execute the following commands:
|
|
|
|
{{- if contains "NodePort" .Values.service.type }}
|
|
|
|
export NODE_IP=$(kubectl get nodes --namespace {{ $releaseNamespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
|
|
export NODE_PORT=$(kubectl get --namespace {{ $releaseNamespace }} -o jsonpath="{.spec.ports[0].nodePort}" svc {{ $pgpoolSvcName }})
|
|
PGPASSWORD="$PASSWORD" psql -h $NODE_IP -p $NODE_PORT {{ $postgresqlCredentials }}
|
|
|
|
{{- 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 {{ $releaseNamespace }} -w {{ $pgpoolSvcName }}
|
|
|
|
export SERVICE_IP=$(kubectl get svc --namespace {{ $releaseNamespace }} {{ $pgpoolSvcName }} --template "{{ "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}" }}")
|
|
PGPASSWORD="$PASSWORD" psql -h $SERVICE_IP -p {{ .Values.service.ports.postgresql }} {{ $postgresqlCredentials }}
|
|
|
|
{{- else if contains "ClusterIP" .Values.service.type }}
|
|
|
|
kubectl port-forward --namespace {{ $releaseNamespace }} svc/{{ $pgpoolSvcName }} {{ .Values.service.ports.postgresql }}:{{ .Values.service.ports.postgresql }} &
|
|
psql -h 127.0.0.1 -p {{ .Values.service.ports.postgresql }} {{ $postgresqlCredentials }}
|
