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 }} --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 -}}
|
|
|
|
{{- $mysqlPasswordValidationErrors := include "common.validations.values.multiple.empty" (dict "required" $requiredPasswords "context" $) -}}
|
|
{{- include "common.errors.upgrade.passwords.empty" (dict "validationErrors" $mysqlPasswordValidationErrors "context" $) -}}
|
|
{{- end }}
|
|
{{- end }}
