Thanks Konstantin

Unfortunately it does not work

The snippet from task manager yaml is

containers:
- name: taskmanager
  image: {{ .Values.image }}:{{ .Values.imageTag }}
  imagePullPolicy: {{ .Values.imagePullPolicy }}
  args:
  - taskmanager -Dtaskmanager.host=$(K8S_POD_IP)
  ports:
  - name: data
    containerPort: 6121
  - name: rpc
    containerPort: 6122
  - name: query
    containerPort: 6125
  env:
  - name: FLINK_CONF_DIR
    value: /etc/flink
  - name: K8S_POD_IP
    valueFrom:
      fieldRef:
        fieldPath: status.podIP
  resources:

The error is

/docker-entrypoint.sh: 62: exec: taskmanager -Dtaskmanager.host=10.131.0.97: not found

Did I misunderstood your instructions?

Hi Boris,

the solution is actually simpler than it sounds from the ticket. The only thing you need to do is to set the "taskmanager.host" to the Pod's IP address in the Flink configuration. The easiest way to do this is to pass this config dynamically via a command-line parameter. 

The Deployment spec could looks something like this:

containers:
- name: taskmanager
  [...]
  args:
  - "taskmanager.sh"
  - "start-foreground"
  - "-Dtaskmanager.host=$(K8S_POD_IP)"
  [...]
  env:
  - name: K8S_POD_IP
    valueFrom:
      fieldRef:
        fieldPath: status.podIP

Hope this helps and let me know if this works. 

Best, 

Konstantin

I was looking at this issue https://issues.apache.org/jira/browse/FLINK-11127

Apparently there is a workaround for it.

Is it possible provide the complete helm chart for it.

Bits and pieces are in the ticket, but it would be nice to see the full chart
