On macOS, both Docker and Podman run a Linux VM. This has some weird effects when running (or writing) your own container registry.

While building my erlang-cluster demonstration project for multi-architecture, using podman, I noticed some weirdness about using FROM --platform=$TARGETPLATFORM.

When I was investigating how to build multi-architecture containers in Podman, I noticed some … oddities. So I wrote them down. I’ll also compare podman’s behaviour to docker’s behaviour.

I noticed some differences between podman on WSL2 and podman on macOS recently. I spent some time investigating.

If you want to use Amazon Elastic Container Registry (ECR) with podman, you’ll do something like this: aws ecr get-login-password ... | podman login .... How does that work?
