** Please be patient while the chart is being deployed **

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 {{ .Release.Namespace }} -l app.kubernetes.io/instance={{ .Release.Name }}
|
|
|
|
Access the pod you want to debug by executing
|
|
|
|
kubectl exec --namespace {{ .Release.Namespace }} -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 startup command
|

PostgreSQL can be accessed through Pgpool via port {{ .Values.service.ports.postgresql }} on the following DNS name from within your cluster:
|
|
|
|
{{ include "postgresql-ha.pgpool" . }}.{{ .Release.Namespace }}.svc.{{ $clusterDomain }}
|
|
|
|
Pgpool acts as a load balancer for PostgreSQL and forward read/write connections to the primary node while read-only connections are forwarded to standby nodes.
|
|
|
|
To get the password for {{ (include "postgresql-ha.postgresqlUsername" .) | quote }} run:
|
|
|
|
export POSTGRES_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ include "postgresql-ha.postgresqlSecretName" . }} -o jsonpath="{.data.password}" | base64 -d)
|
|
|
|
To get the password for {{ (include "postgresql-ha.postgresqlRepmgrUsername" .) | quote }} run:
|
|
|
|
export REPMGR_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ include "postgresql-ha.postgresqlSecretName" . }} -o jsonpath="{.data.repmgr-password}" | base64 -d)
|
|
|
|
To connect to your database run the following command:
|
|
|
|
kubectl run {{ include "common.names.fullname" . }}-client --rm --tty -i --restart='Never' --namespace {{ .Release.Namespace }} --image {{ include "postgresql-ha.postgresql.image" . }} --env="PGPASSWORD=$POSTGRES_PASSWORD" {{ if and (.Values.pgpool.networkPolicy.enabled) (not .Values.pgpool.networkPolicy.allowExternal) }}--labels="{{ include "common.names.fullname" . }}-client=true" {{- end }} \
|

--command -- psql -h {{ include "postgresql-ha.pgpool" . }} -p {{ .Values.service.ports.postgresql }} -U {{ include "postgresql-ha.postgresqlUsername" . }}{{- if not (empty (include "postgresql-ha.postgresqlDatabase" .)) }} -d {{ include "postgresql-ha.postgresqlDatabase" . }}{{- end }}
|
|
|
|
{{- if and (.Values.postgresql.networkPolicy.enabled) (not .Values.postgresql.networkPolicy.allowExternal) }}
|
|
|
|
Note: Since NetworkPolicy is enabled, only pods with label "{{ include "postgresql-ha.postgresql" . }}-client=true" can access postgresql will be able to connect to PostgreSQL.
|
|
|
|
{{- end }}
|
|
|
|
{{- if and (.Values.pgpool.networkPolicy.enabled) (not .Values.pgpool.networkPolicy.allowExternal) }}
|
|
|
|
Note: Since NetworkPolicy is enabled, only pods with label "{{ include "postgresql-ha.pgpool" . }}-client=true" can access postgresql will be able to connect PgPool.
|
|
|
|
{{- 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}")

|
|
|
|
{{- 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 {{ include "postgresql-ha.pgpool" . }}
|
|
|
|
export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ include "postgresql-ha.pgpool" . }} --template "{{ "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}" }}")
