From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I often read that (docker) containers are not good for security. What are secure methods of creating secure isolated environments to run questionable programs in? (lemmy.ml)

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?

Something without the performance hit of VMs

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.
