Errors when customizing kernel for talos

[yumin-l]

I'm customizing kernel for talos with reference to the document(https://www.talos.dev/v1.4/advanced/customizing-the-kernel/). But I got some problems when doing the last step (DOCKER_BUILDKIT=0 docker build --build-arg RM="/lib/modules" -t installer:kernel .). Any ideas for this problem?

seems you're trying from talos 1.5, please follow the Talos 1.5 docs then: https://www.talos.dev/v1.5/advanced/customizing-the-kernel/

Thanks for your quick reply, it works.
But how can I use the customized installer to build Talos and install it? I try to use talosctl upgrade to upgrade my cluster with the customized installer but it didn't work.

that seems like an issue with authenticating to your registry, you either need to setup auth for registry in talos or make the image public
