CHART NAME: {{ .Chart.Name }}
2+
CHART VERSION: {{ .Chart.Version }}
3+
APP VERSION: {{ .Chart.AppVersion }}
4+
5+
** Please be patient while the chart is being deployed **
6+
7+
{{- if .Values.diagnosticMode.enabled }}
8+
The chart has been deployed in diagnostic mode. All probes have been disabled and the command has been overwritten with:
9+
10+
command: {{- include "common.tplvalues.render" (dict "value" .Values.diagnosticMode.command "context" $) | nindent 4 }}
11+
args: {{- include "common.tplvalues.render" (dict "value" .Values.diagnosticMode.args "context" $) | nindent 4 }}
12+
13+
Get the list of pods by executing:
14+
15+
kubectl get pods --namespace {{ include "common.names.namespace" . }} -l app.kubernetes.io/instance={{ .Release.Name }}
16+
17+
Access the pod you want to debug by executing
18+
19+
kubectl exec --namespace {{ include "common.names.namespace" . }} -ti <NAME OF THE POD> -- bash
20+
21+
In order to replicate the container startup scripts execute this command:
22+
23+
/opt/bitnami/scripts/mysql/entrypoint.sh /opt/bitnami/scripts/mysql/run.sh
24+
25+
{{- else }}
26+
27+
Tip:
28+
29+
Watch the deployment status using the command: kubectl get pods -w --namespace {{ include "common.names.namespace" . }}
30+
31+
Services:
32+
33+
echo Primary: {{ include "mysql.primary.fullname" . }}.{{ include "common.names.namespace" . }}.svc.{{ .Values.clusterDomain }}:{{ .Values.primary.service.ports.mysql }}
34+
{{- if eq .Values.architecture "replication" }}
35+
echo Secondary: {{ include "mysql.secondary.fullname" . }}.{{ include "common.names.namespace" . }}.svc.{{ .Values.clusterDomain }}:{{ .Values.secondary.service.ports.mysql }}
36+
{{- end }}
37+
38+
Execute the following to get the administrator credentials:
39+
40+
echo Username: root
41+
MYSQL_ROOT_PASSWORD=$(kubectl get secret --namespace {{ include "common.names.namespace" . }} {{ template "mysql.secretName" . }} -o jsonpath="{.data.mysql-root-password}" | base64 -d)
42+
43+
To connect to your database:
44+
45+
1. Run a pod that you can use as a client:
46+
47+
kubectl run {{ include "common.names.fullname" . }}-client --rm --tty -i --restart='Never' --image {{ template "mysql.image" . }} --namespace {{ include "common.names.namespace" . }} --env MYSQL_ROOT_PASSWORD=$MYSQL_ROOT_PASSWORD --command -- bash
48+
49+
2. To connect to primary service (read/write):
50+
51+
mysql -h {{ include "mysql.primary.fullname" . }}.{{ include "common.names.namespace" . }}.svc.{{ .Values.clusterDomain }} -uroot -p"$MYSQL_ROOT_PASSWORD"
52+
53+
{{- if eq .Values.architecture "replication" }}
54+
55+
3. To connect to secondary service (read-only):
56+
57+
mysql -h {{ include "mysql.secondary.fullname" . }}.{{ include "common.names.namespace" . }}.svc.{{ .Values.clusterDomain }} -uroot -p"$MYSQL_ROOT_PASSWORD"
58+
{{- end }}
59+
60+
{{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
61+
Note: Since NetworkPolicy is enabled, only pods with label {{ template "common.names.fullname" . }}-client=true" will be able to connect to MySQL.
62+
{{- end }}
63+
64+
{{- if .Values.metrics.enabled }}
65+
66+
To access the MySQL Prometheus metrics from outside the cluster execute the following commands:
67+
68+
kubectl port-forward --namespace {{ include "common.names.namespace" . }} svc/{{ printf "%s-metrics" (include "common.names.fullname" .) }} {{ .Values.metrics.service.port }}:{{ .Values.metrics.service.port }} &
69+
curl http://127.0.0.1:{{ .Values.metrics.service.port }}/metrics
70+
71+
{{- end }}
72+
73+
{{ include "mysql.validateValues" . }}
74+
{{ include "mysql.checkRollingTags" . }}
75+
{{- end }}
