clusterctl get kubeconfig results in faulty kubeconfig file after switching to Docker Desktop

[RobinDeBock]

What steps did you take and what happened:

• Removed docker from system
• Clean install of Docker Desktop
• Created a bootstap cluster with Kind
• Created a workload cluster with clusterctl init
• Used clusterctl get kubeconfig on the newly created workload cluster
• Using this kubeconfig file to connect to the cluster results in
  Unable to connect to the server: dial tcp 172.18.0.3:6443: connect: no route to host

What did you expect to happen:
That using clusterctl get kubeconfig results in a working kubeconfig file.

Anything else you would like to add:

• clusterctl get kubeconfig worked correctly before switching to Docker Desktop.
• Using kind get kubeconfig still works.

- In the period of me using setting up the cluster (using `clusterctl get kubeconfig`) and switching to Docker Desktop, an update has been available to clusterctl. I have not installed this one yet and would like to stay on this version if possible.

Environment:

• Cluster-api version: GitVersion:"v1.1.3"
• Minikube/KIND version: v0.12.0 go1.17.8 linux/amd64
• Kubernetes version: (use kubectl version):
  • Client: GitVersion:"v1.22.3"
  • Server, both Kind cluster and workload cluster have version v1.22.7
• OS (e.g. from /etc/os-release): Ubuntu 20.04.4 LTS
• Docker Desktop: 20.10.16

If I understood correctly you got

The connection to the server localhost:8080 was refused - did you specify the right host or port?

when using clusterctl-kubeconfig.yaml ?

Then there is something wrong with the kubectl call. Otherwise it would use https://172.18.0.3:6443 and not the default server URL.

Hey @sbueringer thanks for answering. I retried the setup and came to the conclusion I must have copied the wrong command line output (it was getting pretty crammed after all my trials). Thanks for your understanding.

I have updated the original issue message, the error output is as follows: Unable to connect to the server: dial tcp 172.18.0.3:6443: connect: no route to host

[sbueringer]

Is the cluster entirely reconciled? What does clusterctl describe cluster show? Any recurring errors in controller logs?

[RobinDeBock]

Hey @sbueringer

I'm going to switch back to Docker on the CLI as Docker Desktop uses a VM which impacts performance, so the time to test this setup will be limited.

To come back to your questions:

Is the cluster entirely reconciled?
The cluster is fully operational. As described before, this is the exact same cluster that I was using before. The only difference is that the IP address in the kubeconfig file resulting from clusterctl get kubeconfig is different from the one from kind get kubeconfig and the first one can't be used ot communicate with the cluster. Everything else is working fine.

What does clusterctl describe cluster show?

Any recurring errors in controller logs?
No errors found as the whole clusters seems to be running fine.

Somehow switching to Docker Desktop messed up the networking, but only when using the kubeconfig files from clusterctl get kubeconfig

[sbueringer]

Okay, cluster looks okay. So looks like someone would have to debug the network :). But yeah I wouldn't use Docker desktop with an additional VM on Linux.

@RobinDeBock : you could try if the workaround for MacOS+Docker Desktop works in that case:

Fix kubeconfig (when using docker on MacOS)

[RobinDeBock]

Hey @chrischdi that does seem to have fixed the problem, big thanks!

Maybe add this somewhere more general for other users? As Docker Desktop can be used on every system

[sbueringer]

I think you're the first CAPI user who tried to use CAPD with Docker Desktop on Linux :).
But yeah feel free to open a PR to make the comment a bit more generic.

P.S. the linked section is already linked from the quickstart, I wouldn't move it.
