tl;dr: When using gpg in Containerfile build steps for container images based on Fedora¹-based (39+), ensure you also include gpgconf --kill keyboxd by the end of the same build step. Alternately, and probably better, create a ~/.gnupg directory before the first invocation of gpg.

In our last post, we managed to use Buildah inside of Podman to create new images, but it’s a slow process. We want to be able to iterate on images quickly, so we need to make our build process fast.

I have spent a few weeks figuring out how to change my container development environment from one that uses Docker to one that (almost) completely avoids it.¹
