netstat showing foreign ports as kubernetes:port. What does this mean?
That happens because of the way
netstat renders output. It has nothing to do with actual Kubernetes.
I have Docker Desktop for Windows and it adds this to the hosts file:
# Added by Docker Desktop 192.168.43.196 host.docker.internal 192.168.43.196 gateway.docker.internal # To allow the same kube context to work on the host and the container: 127.0.0.1 kubernetes.docker.internal # End of section
There is a record which maps
netstat renders its output, it resolves foreign address and it looks at the hosts file and sees this record. It says
kubernetes and that is what you see in the console. You can try to change it to
netstat will print:
Proto Local Address Foreign Address State TCP 127.0.0.1:6940 tomato:6941 ESTABLISHED TCP 127.0.0.1:6941 tomato:6940 ESTABLISHED TCP 127.0.0.1:8080 tomato:40347 ESTABLISHED TCP 127.0.0.1:8080 tomato:40348 ESTABLISHED TCP 127.0.0.1:8080 tomato:40349 ESTABLISHED
So what actually happens is there are connections from localhost to localhost (
netstat -b will show apps that create them). Nothing to do with Kubernetes.
It seems that Windows docker changed your
So, if you want to get rid of these connections, just comment out the corresponding lines in the
hosts file on Windows 10 is located in
the records may look something like
I am pretty sure it will disrupt your docker service on Windows (yet, I am not an expert), so don't forget to uncomment these lines whenever you need to get the docker service back.
