I run Docker Swarm at home because my cluster is older, decommissioned machines. The Swarm daemon uses about 50MB of resident memory, which leaves a lot of room to run containers with little overhead.
Anyone know how this compares to k3s? I’ve been using k3s for a while, and there have been a few bugs that made me a bit annoyed
This doesn't answer your question, but I'm piggy-backing with comments on k3s. For me, using k3s for development (not prod), the killer feature is running it in --docker mode where the node uses the local dockerd to run containers (vs. managing its own containerd instance). This allows building images locally with `docker build` and immediately using them in kubernetes pods _without_ first pushing to a (possibly loca…
I was surprised to be unable to otherwise find a good local / remote container development workflow, but this was built to replace what we were previously doing, which is setting DOCKER_HOST to point to the remote (single-node) cluster's Docker daemon (over SSH), so that docker CLI commands would execute on that remote box.
In both cases, you'll still want to take steps to minimize the size of your container image build context, but the size of the images doesn't matter. I'm not sure if it'd fit your needs or not, though.

To some extent, the distributed consensus is kind of the important part. If you have a bunch of components that don't know what state they're supposed to be in, you don't really have a cluster. Looking at the marketing documentation (I didn't read the code), they just wrote their own consensus and datastore instead of using etcd. So the underlying fundamental computer science problems still exist, but nobody has been…

We use it everywhere in my current place of employment and are very satisfied with it.
(maybe it's because we deploy servers using pxe — it makes good ubuntu installs, with no ads in motd & no snapd)

This is very interesting, we're seeing a lot of Kubernetes "flavors" coming out that remove the etcd requirement. It's no secret that etcd is a key part of why Kubernetes is complex--etcd scaling/securing/recovery is really hard. I think Kubernetes would do well to make swapping out the storage backend possible without having all of these forks. Kubernetes is too tightly coupled to etcd, and for little benefit. I wou…
though with kine (kine is not etcd) you can easily use mysql/sqlite/dqlite/postgresql.

I feel an urge to note that ubuntu server is a decent operating system. We use it everywhere in my current place of employment and are very satisfied with it. (maybe it's because we deploy servers using pxe — it makes good ubuntu installs, with no ads in motd & no snapd)
Deploying servers with PXE is fun though. We use PXE and XCAT to manage our fleet. Commissioning ~200 servers in 15 minutes with three commands while sipping coffee is really satisfying.

It looks like Canonical is just using dqlite directly.

I work in this space (being purposefully vague), you are getting a customized image of some sort - PXE really isn't related in this way, that's just a method to get the image onto the destination disk. The official Canonical Ubuntu Cloud Images produced for use this way have the MOTD behaviour and snapd in place based on my exposure to them. https://cloud-images.ubuntu.com/
It doesn't put a "customized image of some sort" on servers, it literally iterates through installer steps with the autoanswers provided by preseed file.
You might say that it is customized since we wrote a preseed file. Well maybe, but it's not a "customized image". Also we didn't write any specific code to remove unwanted packages. It just doesn't install them. No weird packages like byobu :)
