I have defined the values.yaml
like the following:
name: custom-streams
image: streams-docker-images
imagePullPolicy: Always
restartPolicy: Always
replicas: 1
port: 8080
nodeSelector:
nodetype: free
configHocon: |-
streams {
monitoring {
custom {
uri = ${?URI}
method = ${?METHOD}
}
}
}
And configmap.yaml
like the following:
apiVersion: v1
kind: ConfigMap
metadata:
name: custom-streams-configmap
data:
config.hocon: {{ .Values.configHocon | indent 4}}
Lastly, I have defined the deployment.yaml
like the following:
apiVersion: apps/v1
kind: Deployment
metadata:
name: {{ .Values.name }}
spec:
replicas: {{ default 1 .Values.replicas }}
strategy: {}
template:
spec:
containers:
- env:
{{- range $key, $value := .Values.env }}
- name: {{ $key }}
value: {{ $value | quote }}
{{- end }}
image: {{ .Values.image }}
name: {{ .Values.name }}
volumeMounts:
- name: config-hocon
mountPath: /config
ports:
- containerPort: {{ .Values.port }}
restartPolicy: {{ .Values.restartPolicy }}
volumes:
- name: config-hocon
configmap:
name: custom-streams-configmap
items:
- key: config.hocon
path: config.hocon
status: {}
When I run the container via:
helm install --name custom-streams custom-streams -f values.yaml --debug --namespace streaming
Then the pods are running fine, but I cannot see the config.hocon
file in the container:
$ kubectl exec -it custom-streams-55b45b7756-fb292 sh -n streaming
/ # ls
...
config
...
/ # cd config/
/config # ls
/config #
I need the config.hocon
written in the /config
folder. Can anyone let me know what is wrong with the configurations?
I was able to resolve the issue. The issue was using configmap
in place configMap
in deployment.yaml
:
apiVersion: apps/v1
kind: Deployment
metadata:
name: {{ .Values.name }}
spec:
replicas: {{ default 1 .Values.replicas }}
strategy: {}
template:
spec:
containers:
- env:
{{- range $key, $value := .Values.env }}
- name: {{ $key }}
value: {{ $value | quote }}
{{- end }}
image: {{ .Values.image }}
name: {{ .Values.name }}
volumeMounts:
- name: config-hocon
mountPath: /config
ports:
- containerPort: {{ .Values.port }}
restartPolicy: {{ .Values.restartPolicy }}
volumes:
- name: config-hocon
configMap:
name: custom-streams-configmap
items:
- key: config.hocon
path: config.hocon
status: {}
