CHART NAME: {{ .Chart.Name }}
CHART VERSION: {{ .Chart.Version }}
APP VERSION: {{ .Chart.AppVersion }}

** 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 {{ .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 execute this command:

    /opt/bitnami/scripts/mysql/entrypoint.sh /opt/bitnami/scripts/mysql/run.sh

{{- else }}

Tip:

  Watch the deployment status using the command: kubectl get pods -w --namespace {{ .Release.Namespace }}

Services:

  echo Primary: {{ include "mysql.primary.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }}:{{ .Values.primary.service.port }}
{{- if eq .Values.architecture "replication" }}
  echo Secondary: {{ include "mysql.secondary.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }}:{{ .Values.secondary.service.port }}
{{- end }}

Execute the following to get the administrator credentials:

  echo Username: root
  MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "mysql.secretName" . }} -o jsonpath="{.data.mysql-root-password}" | base64 --decode)

To connect to your database:

  1. Run a pod that you can use as a client:

      kubectl run {{ include "common.names.fullname" . }}-client --rm --tty -i --restart='Never' --image  {{ template "mysql.image" . }} --namespace {{ .Release.Namespace }} --env MYSQL_ROOT_PASSWORD=$MYSQL_ROOT_PASSWORD --command -- bash

  2. To connect to primary service (read/write):

      mysql -h {{ include "mysql.primary.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }} -uroot -p"$MYSQL_ROOT_PASSWORD"

{{- if eq .Values.architecture "replication" }}

  3. To connect to secondary service (read-only):

      mysql -h {{ include "mysql.secondary.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }} -uroot -p"$MYSQL_ROOT_PASSWORD"
{{- end }}

{{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
Note: Since NetworkPolicy is enabled, only pods with label {{ template "common.names.fullname" . }}-client=true" will be able to connect to MySQL.
{{- end }}

{{- if .Values.metrics.enabled }}

To access the MySQL Prometheus metrics from outside the cluster execute the following commands:

    kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ printf "%s-metrics" (include "common.names.fullname" .) }} {{ .Values.metrics.service.port }}:{{ .Values.metrics.service.port }} &
    curl http://127.0.0.1:{{ .Values.metrics.service.port }}/metrics

{{- end }}

To upgrade this helm chart:

  1. Obtain the password as described on the 'Administrator credentials' section and set the 'root.password' parameter as shown below:

      ROOT_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ include "common.names.fullname" . }} -o jsonpath="{.data.mysql-root-password}" | base64 --decode)
      helm upgrade --namespace {{ .Release.Namespace }} {{ .Release.Name }} bitnami/mysql --set auth.rootPassword=$ROOT_PASSWORD

{{ include "mysql.validateValues" . }}
{{ include "mysql.checkRollingTags" . }}
{{- if and (not .Values.auth.existingSecret) (not .Values.auth.customPasswordFiles) -}}
    {{- $secretName := include "mysql.secretName" . -}}
    {{- $requiredPasswords := list -}}

    {{- $requiredRootPassword := dict "valueKey" "auth.rootPassword" "secret" $secretName "field" "mysql-root-password" -}}
    {{- $requiredPasswords = append $requiredPasswords $requiredRootPassword -}}

    {{- if not (empty .Values.auth.username) -}}
        {{- $requiredPassword := dict "valueKey" "auth.password" "secret" $secretName "field" "mysql-password" -}}
        {{- $requiredPasswords = append $requiredPasswords $requiredPassword -}}
    {{- end -}}

    {{- if (eq .Values.architecture "replication") -}}
        {{- $requiredReplicationPassword := dict "valueKey" "auth.replicationPassword" "secret" $secretName "field" "mysql-replication-password" -}}
        {{- $requiredPasswords = append $requiredPasswords $requiredReplicationPassword -}}
    {{- end -}}
{{- end }}
{{- end }}
