Is it possible to connect to a host port from a rootless Docker container?
The official docs list some known limitations of rootless Docker, and says that "Host network (docker run --net=host) is also namespaced inside RootlessKit." I don't understand how RootlessKit works, but I am wondering if this means that rootless Docker containers are unable to connect to ports on the host? I also checked the RootlessKit docs but I'm out of my depth there: (https://github.com/rootless-containers/rootlesskit/blob/master/docs/network.md).
- Rootless or rootful for home NAS?

Hetzner now provides IPv6 only dedicated servers
Fair Warning: If your app needs to be able to see the user's IP (for throttling, banning, etc.)
Rootless Docker doesn't properly support IPv6 yet with the ability to see the end-users source IP.

How to improve your Docker containers security – [cheat sheet]
There may be some overhead with networking if your application uses a very large amount of bandwidth. See:
https://github.com/rootless-containers/rootlesskit/tree/v0.1...
Otherwise for general dockerized applications, you won't notice any difference.
You may find some quirks, but these can all be worked around easily as described on the rootless docker page.
We run it in production with no issues so far.

Fedora 34 and docker rootless insanity. Warning: rant-y
Now with Fedora 34 I'm having issues from rootlesskit not being packaged. Got the binaries from https://github.com/rootless-containers/rootlesskit/#setup since that go get command never works. I have installed over 50 packages using go get but rootlesskit ALWAYS fails to compile because of some dependency like google/uuid and different Go versions.
- Fedora 34 doesn't have rootlesskit for Docker/Moby?

Release Radar • March 2024 Edition
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.

Choosing a Name for Your Computer
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/...

Do not install Docker Desktop on GNU/Linux systems
Try to use moby instead since that is the engine in Docker.

Exploring Podman: A More Secure Docker Alternative
> 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`)

OpenZFS 2.2: Block Cloning, Linux Containers, BLAKE3
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.
