Hi there!

I wanted to give you some resources that should be able to help you out.

First, here is a step-by-step guide on installing cert-manager on LKE:

What is Kubernetes cert-manager?

There is a section on Challenges - which is what you're looking for in regard to the DNS-01 Challenger Provider.

Next, you can refer to the official cert-manager documentation for the DNS-01, which will show you how to configure it:

DNS01

I'm looking for the same thing. It appears Linode is not a supported DNS provider in cert-manager. This would make it much easier to setup cert-manager with Linode DNS if Linode DNS was supported here.

However, it appears that additional DNS providers will not be supported in-tree and should be implemented as a webhook provider instead.

I did find this project which implements a DNS01 resolver for Linode DNS. https://github.com/slicen/cert-manager-webhook-linode . It would be great if Linode would maintain and support such a solver.

I just ended up with annotations to do the TLS.

this thread motivated us to write another cert-manager adapter for linode: https://github.com/monostream/cert-manager-linode

maybe it's helpful for you too. the one linked by @kekoav has not worked for us using subdomains.

cheers, adrian
