Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Podman Desktop: A Free OSS Alternative to Docker Desktop
You are probably referring to Sysbox (https://github.com/nestybox/sysbox), which I believe will meet your requirements (systemd, inner containers, security, etc).
Btw, Sysbox is already supported in Docker-Desktop (business tier only), so you can easily do what you want with this instruction:
$ docker run -it --rm -e SYSBOX_SYSCONT_MODE=TRUE nestybox/ubuntu-focal-systemd-docker:latest bash
Disclaimer: I'm Sysbox's co-creator and currently working for Docker.

SELinux is unmanageable; just turn it off if it gets in your way
One project in this space that looked quite promising to me is sysbox[0]. I've used them once for a gitlab runner set-up similar to what is described in their blog[1].
It's currently working great and I have not had any major crashes/incidents for at least the past 8 months.

Jenkins in Docker: Running Docker in a Jenkins container
Today, things are very different. Docker-in-Docker has a more secure and safe approach with rootless containers and freemium tools like sysbox. Tools like sysbox let you run Docker-in-Docker without the -privileged flag and optimizes specific scenarios, like running multiple nodes of a Kubernetes cluster as ordinary containers.

Run untrusted code in sandbox
Right now I am going with sysbox rootless containers. https://github.com/nestybox/sysbox

Real-world stories of how we’ve compromised CI/CD pipelines
We’ve been using Sysbox (https://github.com/nestybox/sysbox) for our Buildkite based CI/CD setup, allows docker-in-docker without privileged containers. Paired with careful IAM/STS design we’ve ended up with isolated job containers with their own IAM roles limited to least-privilege.

Individual Docker Desktops vs hosting on a server?
A good alternative to the VM approach is to use Kubernetes + Sysbox (a next-gen "runc", free, open-source).
- Sysbox now works on K8s v1.21

Does running a container with privileged mode turn on allow code to escape into the Host ?
But nowadays there is an option to run such software in containers securely. It's called Sysbox, and it's a new "runc" (the piece of software that creates the containers). I am one of the developers, so I am biased, but I think you'll find it helpful.

Sandboxing All the Things with Flatpak and BubbleBox
bubblewrap is designed as a low-level too. There is nothing quick and dirty about it. It disallows everything by default and you have to be explicit about what you want to share with the host. If your application needs complex permissions/resources, then you will need to have a complex bubblewrap command line.
Once you have figured out which permissions/resources you need for a given program, you can wrap the command line invocation in a shell script.
If you want other people to do the work of defining permissions/resources, then have a look at firejail: https://github.com/netblue30/firejail

Ask HN: What are some unpopular technologies you wish people knew more about?
Firejail is cool: https://github.com/netblue30/firejail
Linux namespaces/cgroups but nowhere near as heavy as Docker.
I use it when I want to limit the memory of a Python script:

Toolship: A (More) Secure Workstation
Firejail can also be a useful option, though no good if you're on Mac https://firejail.wordpress.com/
Uses the same Linux primitives as docker etc, but can be a bit more ergonomic for this use case

Firejail: Light, featureful and zero-dependency security sandbox for Linux
Firejail, Flatpak (which uses Bubblewrap under the hood), and Snap (which uses AppArmor) all use the same underlying technology: Linux namespaces.
This question comes up a lot, and has been answered here: https://github.com/netblue30/firejail/wiki/Frequently-Asked-...
TL;DR: Firejail has much more comprehensive features than Flatpak (Bubblewrap). Firejail also has more comprehensive network support, support for AppArmor and SELinux, and easier seccomp filtering.
Compared to Snap (which uses AppArmor), Firejail is compatible with AppArmor and again goes above and beyond with a lot of additional features.

Bubblewrap – Low-level unprivileged sandboxing tool used by Flatpak
Wonderful little tool, too bad you must chain various exec calling tools to get cgroups (a bit akin to `ionice ... nice ... cmd`) and Linux users namespaces can't allow UNIX sockets while preventing network access (I think?).
Migrated from Firejail when its complexity annoyed me too much and I hit https://github.com/netblue30/firejail/issues/3001 (Firejail doesn't like parens or brackets in --put/--get parameters) to a badly NIH version using bwrap and bash to have "profiles":
- Firejail: Light featureful and zero-dependency security sandbox for Linux
-
Do, or do not. There is no try
Firejail does this. The profile database is the two "profile" directories in https://github.com/netblue30/firejail/tree/master/etc

What do you mean by a Firefox container? Do you mean FireJail?
What are some alternatives?
