how to access pods from host?

Question

I'm running colima with kubernetes like: colima start --kuberenetes

I created a few running pods, and I want to see access the through the browsers. But I don't know what is the colima IP (or kubernetes node IP).

help appreciated

Answer 1

You can get the nodeIp so:

kubectl get node

NAME       STATUS   ROLES    AGE   VERSION
nodeName   Ready    <none>   15h   v1.26.0

Then with the nodeName:

kubectl describe node nodeName

That gives you a descrition of the node and you should look for this section:

Addresses:
  InternalIP:  10.165.39.165
  Hostname:    master

Ping it to verify the network.

Find your host file on Mac and make an entry like:

10.165.39.165 test.local

This let you access the cluster with a domain name.

Ping it to verify.

You can not access from outside the cluster a ClusterIp. To access your pod you have several possibilities.

1. if your service is type ClusterIp, you can create a temporary connection from your host with a port forward.

kubectl port-forward svc/yourservicename localport:podport

2. (i would raccomend this) create a service type: NodePort

Then

kubectl get svc -o wide

Shows you the NodePort: between(30000-32000).

You can access now the Pod by: test.local:nodePort or Ipaddress:NodePort.

Note: If you deployed in a namespace other than default, add -n yournamespace in the kubectl commands.

Update:

if you want to start colima with an ipAddress, first find one of your local network which is available.

Your network setting you can get with:

ifconfig

find the network. Should be the same of that of your Internet router.

Look for the subnet. Most likely 255.255.255.0.

The value to pass then:

  --network-address xxx.xxx.xxx.xxx/24

In case the subnet is 255.255.0.0 then /16. But i dont think, if you are connect from home. Inside a company however this is possible.

Again check with ping and follow the steps from begining to verify the kubernetes node configuration.
