How can I experience this new feature on 3.0?

[LinuxSuRen]

hi @weekyuan, of course. Welcome! But please make sure DO NOT test it in any official environment yet. I highly suggest that you test it in a personal or temporary environment. Because it has not been released yet.

OK. I guess you're all ready to go. Let's rock it. There're four components you need to update:

• ks-apiserver --> kubespheredev/ks-apiserver
• ks-controller-manager --> kubespheredev/ks-controller-manager
• ks-console --> kubespheredev/ks-console
• ks-jenkins --> kubespheredev/ks-jenkins:2.249.1

After you updated these deployments with the latest container images. You can create a multi-branch pipeline with Gitlab. But there's still a couple of things you might need to know.

Restriction

• You need to add a Gitlab server on the global configuration page of Jenkins manually
• You need to type the Gitlab server on Kubersphere, please make sure you type the exact same string
• You can only use the public service of Gitlab instead of a private Gitlab until Add credential selection support for Gitlab multi-branch pipeline console#1361
