** 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/cassandra/entrypoint.sh /opt/bitnami/scripts/cassandra/run.sh
|
|
|
|
{{- else }}
|
|
|
|
Cassandra can be accessed through the following URLs from within the cluster:
|
|
|
|
- CQL: {{ include "common.names.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }}:{{ .Values.service.ports.cql }}
|
|
|
|
To get your password run:
|
|
|
|
{{ include "common.utils.secret.getvalue" (dict "secret" $cassandraSecretName "field" $cassandraPasswordKey "context" $) }}
|
|
|
|
Check the cluster status by running:
|
|
|
|
kubectl exec -it --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app.kubernetes.io/name={{ include "common.names.name" . }},app.kubernetes.io/instance={{ .Release.Name }} -o jsonpath='{.items[0].metadata.name}') nodetool status
|
|
|
|
To connect to your Cassandra cluster using CQL:
|
|
|
|
1. Run a Cassandra pod that you can use as a client:
|
|
|
|
kubectl run --namespace {{ .Release.Namespace }} {{ include "common.names.fullname" . }}-client --rm --tty -i --restart='Never' \
|
|
--env CASSANDRA_PASSWORD=$CASSANDRA_PASSWORD \
|
|
{{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}--labels="{{ include "common.names.name" . }}-client=true"{{ end }} \
|
|
--image {{ include "cassandra.image" . }} -- bash
|
|
|
|
2. Connect using the cqlsh client:
|
|
|
|
cqlsh -u {{ .Values.dbUser.user }} -p $CASSANDRA_PASSWORD {{ include "common.names.fullname" . }}
|
|
|
|
{{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
|
|
Note: Since NetworkPolicy is enabled, only pods with the label below will be able to connect to Cassandra:
|
|
|
|
"{{ include "common.names.fullname" . }}-client=true"
|
|
|
|
{{- else -}}
|
|
|
|
To connect to your database from outside the cluster execute the following commands:
|
|
|
|
{{- if contains "NodePort" .Values.service.type }}
|
|
|
|
export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
|
|
export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ include "common.names.fullname" . }})
|
|
|
|
cqlsh -u {{ .Values.dbUser.user }} -p $CASSANDRA_PASSWORD $NODE_IP $NODE_PORT
|
|
|
|
{{- else if contains "LoadBalancer" .Values.service.type }}
|
|
|
|
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
|
|
Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ include "common.names.fullname" . }}'
|
|
|
|
export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ include "common.names.fullname" . }} --template "{{ "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}" }}")
|
|
cqlsh -u {{ .Values.dbUser.user }} -p $CASSANDRA_PASSWORD $SERVICE_IP
|
|
|
|
{{- else if contains "ClusterIP" .Values.service.type }}
|
|
|
|
kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ include "common.names.fullname" . }} {{ .Values.service.ports.cql }}:{{ .Values.service.ports.cql }} &
|
|
cqlsh -u {{ .Values.dbUser.user }} -p $CASSANDRA_PASSWORD 127.0.0.1 {{ .Values.service.ports.cql }}
|
|
|
|
{{- end }}

{{- end }}

{{- end }}
