Installation on a kind cluster

[doru1004]

Hello,

I'm trying to use Camel K in conjunction with a kind cluster I'm running locally, are there any additional configuration steps that I need to do for this cluster type? When trying to run the example the builder is stuck initializing and the eventually times out.

Just to check, are there any pre-requisites that are not mentioned explicitly in the README that I need to satisfy before running Camel K?

Thanks a lot!

Out of curiosity, what's a "kind cluster"?

[heiko-braun]

Ah, I see: https://kind.sigs.k8s.io/

[davsclaus]

Oh yeah its a new kubernetes distribution. I have not personally tried with kind yet. Vanilla kubernetes or minikube works.

Did you try installing with the latest nighty build of camel-k or was it the old RC2 build?

We do use kind in our integration tests, see:

https://github.com/apache/camel-k/blob/master/.github/workflows/kubernetes.yml

I created my kind cluster with a local registry.

Then I ran:

kamel install --registry=http://localhost:5000 --force

( If I don't run it with --registry then it prints "Error: cannot find automatically a registry where to push images" but the kamel operator pod continues to set up and reaches "Running" state. I'd expect it to fail completely and not even start but that's not the case).

After I do this I do:

git clone git@github.com:apache/camel-k.git
cd camel-k
kamel run examples/Sample.java

The output of that last instruction is:

integration "sample" created

But when I look at the pods I get:

camel-k $ kubectl get pods -w

Any help is welcome.

Did you try installing with the latest nighty build of camel-k or was it the old RC2 build?

I am using the latest nightly build.

[doru1004]

Started using kamel from RC2.

Installation steps (the ones that have gotten me the furthest):

kamel install --cluster-setup
kamel install --registry=localhost:5000 --registry-insecure --force

After this I see:

> kubectl get pods
camel-k-operator-8d68bb8cb-hgv9n           1/1     Running      0          2m29s

But ...

When running:

kamel run examples/Sample.java

the builder pod ('camel-k-kit-br7e120nhkmmt13821n0-builder') gets to the 'Running' stage (for a bit) before it errors:

Any ideas what's going on?

Any ideas what might be going wrong here?

[orpiske]

I've took notes of running Camel K with Kind and with Kind + A Local Registry. I'll open a PR tomorrow with the details for this.

[orpiske]

I added notes about installing Camel K on Kind and they should be available on the website soon, therefore closing it.

Disclaimer: non-official documentation/steps below.

As an additional comment about the failure above. The problem Get http://localhost:5000/v2/: dial tcp [::1]:5000: connect: connection refused is likely caused because there is a problem in the script (the script available on Kind website) that is normally used to setup Kind with a local registry.
