{{- 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 {{ include "common.names.namespace" . }} -l app.kubernetes.io/instance={{ .Release.Name }}
|
|
|
|
Access the pod you want to debug by executing
|
|
|
|
kubectl exec --namespace {{ include "common.names.namespace" . }} -ti <NAME OF THE POD> -- bash
|
|
|
|
In order to replicate the container startup scripts execute this command:
|
|
|
|
/opt/bitnami/scripts/mariadb-galera/entrypoint.sh /opt/bitnami/scripts/mariadb-galera/run.sh
|
|
|
|
{{- else }}
|
|
Tip:
|
|
|
|
Watch the deployment status using the command:
|
|
|
|
kubectl get sts -w --namespace {{ include "common.names.namespace" . }} -l app.kubernetes.io/instance={{ .Release.Name }}
|
|
|
|
MariaDB can be accessed via port "{{ .Values.service.ports.mysql }}" on the following DNS name from within your cluster:
|
|
|
|
{{ template "common.names.fullname" . }}.{{ include "common.names.namespace" . }}.svc.{{ .Values.clusterDomain }}
|
|
|
|
To obtain the password for the MariaDB admin user run the following command:
|
|
|
|
echo "$(kubectl get secret --namespace {{ include "common.names.namespace" . }} {{ if .Values.existingSecret }}{{ .Values.existingSecret }}{{ else }}{{ template "common.names.fullname" . }}{{ end }} -o jsonpath="{.data.mariadb-root-password}" | base64 -d)"
|
|
|
|
To connect to your database run the following command:
|
|
|
|
kubectl run {{ template "common.names.fullname" . }}-client --rm --tty -i --restart='Never' --namespace {{ include "common.names.namespace" . }} --image {{ template "mariadb-galera.image" . }} --command \
|
|
-- mysql -h {{ template "common.names.fullname" . }} -P {{ .Values.service.ports.mysql }} -u{{ if .Values.db.user }}{{ .Values.db.user }}{{ else }}{{ .Values.rootUser.user }}{{ end }} -p{{ if .Values.db.user }}$(kubectl get secret --namespace {{ include "common.names.namespace" . }} {{ if .Values.existingSecret }}{{ .Values.existingSecret }}{{ else }}{{ template "common.names.fullname" . }}{{ end }} -o jsonpath="{.data.mariadb-password}" | base64 -d){{ else }}$(kubectl get secret --namespace {{ include "common.names.namespace" . }} {{ if .Values.existingSecret }}{{ .Values.existingSecret }}{{ else }}{{ template "common.names.fullname" . }}{{ end }} -o jsonpath="{.data.mariadb-root-password}" | base64 -d){{ end }} {{ .Values.db.name }}
|
|
|
|
To connect to your database from outside the cluster execute the following commands:
|
|
|
|
{{- if contains "NodePort" .Values.service.type }}
|
|
|
|
export NODE_IP=$(kubectl get nodes --namespace {{ include "common.names.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 {{ include "common.names.namespace" . }} -w {{ template "common.names.fullname" . }}'
|
|
|
|
export SERVICE_IP=$(kubectl get svc --namespace {{ include "common.names.namespace" . }} {{ template "common.names.fullname" . }} --template "{{ "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}" }}")

To access the MariaDB Prometheus metrics from outside the cluster execute the following commands:
|
|
|
|
kubectl port-forward --namespace {{ include "common.names.namespace" . }} svc/{{ template "common.names.fullname" . }}-metrics {{ .Values.metrics.service.port }}:{{ .Values.metrics.service.port }} &
|
