Quickstart installation fails on runtimes installation step [main branch]

[mzegla]

Hi,

Some time ago I used quickstart guide to quickly install ModelMesh on my K8S cluster and it all went smoothly.
In that guide there's a part with:

RELEASE=release-0.10
git clone -b $RELEASE --depth 1 --single-branch https://github.com/kserve/modelmesh-serving.git
cd modelmesh-serving

Today I wanted to install ModelMesh from the main branch (with --enable-self-signed-ca in installation options), but failed on servingruntimes installation step with error:

Installing ModelMesh Serving built-in runtimes

I suppose this may be related to the changes regarding certificates and cert manager introduced since the 0.10 release am I right?
Have you seen such errors?

I've seen similar issue mentioned in cert-manager docs: https://cert-manager.io/docs/troubleshooting/webhook/#error-service-unavailable and the cause seem to be unknown.
I'd appreciate any help or guidance on how to solve this.

Sorry for the inconvenience Miłosz. @rafvasq fixed the docs removing the self-signed certificate option until we have the v0.11.0 release ready.

Thanks Christian, so I guess that if I wanted to work with the latest ModelMesh (assuming I'd like to contribute at some point and want to test with the latest changes) I should have cert manager set up on my cluster?
