For some reason, e2e is failing. I'm debugging locally, but in the meantime, I guess it would be good to catch an improvement here: since we're importing the whole Kubernetes code-base, we can take advantage of the advanced defaults for the I'm sharing my patch here, it would be great if you could apply it. diff --git a/internal/kubeadm/uploadconfig.go b/internal/kubeadm/uploadconfig.go

Hi @prometherion I tried your patch, and found that it is not working for some reason, nodes can't join to the cluster for some reason: Unfortunately I wasn't investigated the reason, just running busy all the time, sorry :0 |
|
@kvaps may I ask you which version gave you that error? Tested my changes with a v1.30 node and it worked smoothly. edit: my proposed changes are working with v1.30, v1.29, v1.28: starting from v1.27 there's a marshaling error:
I found a way to have backward compatibility, if you don't mind @kvaps I would push the changes to your branch: no pressure at all, I can open a different PR if you want to review without losing your contributions. With this, we'll be able still to spin TCP pre and post v1.27 🎉 |
|
I used v1.30. Sorry push or open new PR, I don't mind :) |

Thanks for the tests and the contributions, Andrei, just merged #542 which superseded this one. |
