I am attempting to setup Kubernetes locally using a docker instance. I am following this documentation but get stuck at the point of creating a new service and exposing the ports.
I have the docker container pulled and I have a kubectl
available.
When I run the command kubectl get nodes --show-labels
I get the following
|NAME | STATUS | AGE | LABELS | |-----------|---------|--------|--------------------------------------| |127.0.0.1 | Ready | 1h | kubernetes.io/hostname=127.0.0.1 |
I now create a new service with kubectl run nginx --image=nginx --port=80
as per the docs. When I run docker ps
I see a container that's been created using my local nginx:latest image.
CONTAINER_ID: 4192d1b423ec IMAGE: nginx COMMAND: "nginx -g 'daemon off'" CREATED: 37 minutes ago STATUS: Up 37 minutes NAMES: k8s_nginx.aab52821_nginx-198147104-qop91_default_f1cf5d8a-ef2d-11e5-b527-f0def1de109f_940ee216
The next step is where I'm having problems kubectl expose rc nginx --port=80
is supposed to expose the nginx image as a kubernetes service on port 80.
I get this in the terminal.
Error from server: replicationcontrollers "nginx" not found
So I started reading about replicationcontrollers, I understand the concepts but I do not know how they are configured or setup. This got me to thinking that I'm following what should be an idiot proof setup guide. Can anyone help me with this? I have added my docker and kubernetes versions below.
