Linux

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'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

Do you think Podman is ready to take over Docker? My understanding is that Podman is Docker without the root requirement.

Related to this: can podman completely replace Docker? I.e., can it pull containers and build containers in addition to running them?

It can pull and build containers fine but last time I tried there were some differences. Mounts were not usable because user uid/gid behave quite differently. Tools like portainer dont work on podman containers. I havent tried out any networking or advanced stuff yet.

But i found that the considerations to write docker files are quite different for podman.

Gotcha. I use docker containers on computing clusters at the University, but because of security, I have to convert them to singularity containers. That is okay, but I was hoping that by running podman I could prevent this extra step.
