Image Swap Mutating Admission Webhook for Kubernetes

Project mention: Air gapped on prem install - what would you do? | /r/kubernetes | 2023-07-01

We have on premise clusters built that only have access to internal sites, no access to the internet. We've done this with 2 versions of K8s. The first we used a tool that was created in house. The guy who built it put it up on GitHub. It is the imageswap web hook. I haven't kept up with it since we've stopped using it, but it used to take everything other than the image name and tag and swap it with whatever we set. So, something like "webdevops/toolbox:latest" would be changed to "registry.internal.org/images/toolbox:latest" if we set our registry and path to "registry.internal.org/images". Then we'd just stage all of the necessary images in that image registry. You could choose which namespaces to label to use the image swap and which to leave alone.
