#Portforward install

This field is purely informational and does not carry any configuration to be made. If you mean that you've included the - containerPort: 8080. I even tried exposing port 7077 in YAML file. It will work and won't produce the error mentioned ( socat).

#Portforward install

Try to exec into it and run $ apt update & apt install -y nginx and try to curl again (with kubectl port-forward configured). It will fail as nothing listens on its port. You can simulate it by running an Ubuntu Pod where you try to curl its port 80. This would also work on a Pod that application haven't bound to the port and/or is not listening.

$ kubectl port-forward deployment/nginx 8080:1234.

If we made a change to the port-forward command like below (notice the 1234 port):

$ kubectl port-forward deployment/nginx 8080:80Įverything should be correct and the NGINX welcome page should appear when running: $ curl localhost:8080.

$ kubectl create deployment nginx -image=nginx.

I've managed to reproduce this error with a Kubernetes cluster created with kubespray.Īssuming that you've run following steps:

Mismatch between the ports that request is sent to and the receiving end (for example sending a request to an NGINX instance on port: 1234).

TerminationMessagePath: /dev/termination-logįocusing specifically on the error from the Kubernetes perspective it could be related to: | tar xz mv spark-2.2.2-bin-hadoop2.7 spark curl -sSLO

SelfLink: /apis/apps/v1beta1/namespaces/default/statefulsets/m3-zeppelin This is the YAML file used for deployment. I already tried installing socat on the kubernetes. from pyspark import SparkContext, SparkConfĬonf = SparkConf().setMaster("spark://localhost:7077").setAppName("Stand Alone Python Script")

I am getting error in the lines where conf is defined. I am getting this error while executing my python file. I am trying to port forward to my local machine. I am running pyspark on one of the ports of kubernetes.
