Error Starting PyFlink in Kubernetes Session Cluster "Could Not Get
Rest Endpoint"
Trying to spin up a Python Flink instance in my Kubernetes cluster with
this configuration ...
sudo ./bin/flink run \
--target kubernetes-session \
-Dkubernetes.cluster-id=flink-python \
-Dkubernetes.namespace=cmdaa \
-Dkubernetes.container.image=cmdaa/pyflink:0.0.1 \
--pyModule word_count \
--pyFiles /opt/flink-1.12.2/examples/python/table/batch/word_count.py
... But getting this error:

Re: Error Starting PyFlink in Kubernetes Session Cluster "Could Not

Posted by Yang Wang <da...@gmail.com>.
What I mean is you could create a K8s deployment using the Flink image just
like following.
After then, you could use "kubectl exec -it {pod_name} bash" to tunnel in
and submit the Flink
python application to the existing session cluster.
apiVersion: apps/v1
kind: Deployment
metadata:
name: flink-client
spec:
replicas: 1
selector:
matchLabels:
app: flink-client
template:
metadata:
labels:
app: flink-client
spec:
containers:
- name: client
image: flink:1.12.2
imagePullPolicy: Always
args: ["sleep", "86400"]
Best,
Yang

Yang,
"... This could be done by starting a pod as the Flink client."
Do you have an example yaml you could share?

Re: Error Starting PyFlink in Kubernetes Session Cluster "Could Not

Posted by Yang Wang <da...@gmail.com>.
I think you want to submit a Flink python job to the existing session
cluster.
Please ensure the session cluster is created with proper service exposed
type[1].
* LoadBalancer for the cloud environment
* NodePort for self managed K8s cluster
* ClusterIP for the K8s internal submission, which means you should submit
the Flink application in the K8s cluster. This could be done by starting a
pod as the Flink client.
