I’ve read that standard containers are optimized for developer productivity and not security, which makes sense.
But then what would be ideal to use for security? Suppose I want to isolate environments from each other for security purposes, to run questionable programs or reduce attack surface. What are some secure solutions?

Podman supports dockerfile, right?
Yes.
Unlike docker, podman doesn’t try to do everything on it’s own. There’s a separate tool known as
buildah
which builds containers from dockerfiles just fine.Ps. More generally, they’re called containerfiles.
