Moby VS podman-desktop-companion

Having been featured in our February 2023, and January 2024 Release Radars, Moby is the original Linux Container runtime. This new version adds a bunch of changes to the Docker CLI and Moby itself with additional features. There's bug fixes and enhancements, with the main thing for users to be on the look out for containers that were created using Docker Engine 25.0.0. These containers might have duplicate MAC addresses, and thus must be recreated. The same goes for those containers created with Moby 25.0+ and with user defined MAC addresses. Read up on all these changes in the release notes.

Formlabs does this as well for their 3d printers, my earliest encounter of this was when Docker started getting popular: https://github.com/moby/moby/blob/master/pkg/namesgenerator/...

Try to use moby instead since that is the engine in Docker.

> Podman is designed to help with this by providing stronger default security settings compared to Docker. Features like rootless containers, user namespaces, and seccomp profiles, while available in Docker, aren't enabled by default and often require extra setup.

Seccomp has been enabled by default since 2015: https://github.com/moby/moby/pull/18780

It is true that Rootless isn't enabled by default but its "extra setup" can be done with a single command (`dockerd-rootless-setuptool.sh install`)

Perhaps.

Thing is, https://github.com/moby/moby/blob/670bc0a46c4ca03b75f1e72f73... is using https://github.com/mistifyio/go-zfs which features code like `out, err := zfsOutput("get", "-H", key, d.Name)` (Source: https://github.com/mistifyio/go-zfs/blob/master/zfs.go#L315) to get a single zfs property.

Somebody chose to use a library as abstraction that looks good but is implemented as a MVP (nothing wrong with that). "In the future, we hope to work directly with libzfs" should have raised an alarm somewhere, though.

AppArmor can restrict /proc and this is even used by docker: https://github.com/moby/moby/blob/master/contrib/apparmor/te...

Btw #2: For a nice, cross-platform GUI app thing for Docker & Podman here's this one: Podman Desktop Companion.

Podman Desktop Companion (cross-platform, supports Docker too)

Docker in WSL2 too works but with Podman the environment setup may be a little more flexible depending on what you want to achieve on what distro etc. In any case you can use the cross-platform Podman Desktop Companion app to manage your containers via a GUI.

Both Distrobox and Podman can be installed without root access btw and, here's a neat little GUI for managing Podman & Docker containers: Podman Desktop Companion (cross-platform).

No, that's incorrect. Also, there's the unofficial Pods app, and the Podman Desktop Companion.

For a GUI to manage your Podman and/or Docker containers, install the Podman Desktop Companion app (yes, it supports both Podman and Docker). They say that the Windows version can be used to manage the containers running in WSL2 but a more sure way would be to pick the Linux app and to install it in the WSL2 distro your containers are installed & running in.

I'm skeptic how long this will last unless they bring out some cutting-edge innovations. I frankly used and loved Docker Desktop for a long time because it was the easiest way to get going and I believe even k8s is included now which is great for hobbyists and those who just want to get things done. But, I've been annoyed by the UX changes and the push to login to docker hub.

While in 2023, there are most certainly great alternatives that are relatively easy to install from the terminal and get going, I guess there's not yet a definitive replacement that comes with the GUI too. Best I can think of is Podman Desktop Companion[1] but not sure how well this works.

How does this compare to Podman Desktop Companion? They look very similar - nearly identical - yet clearly two different projects.
