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.

Show HN: Bocker-compose, the missing layer to Docker-compose
A (joke?) one-liner I came up with while thinking about solutions to centralized container management across multiple SSH hosts. Shame on me.
The name is inspired by bocker [0], albeit this doesn't re-implement docker-compose in bash, I found it to be fitting enough.
I'd love to see someone come up with a smarter and/or shorter way to do this.

Barco: Linux Containers from Scratch in C
When I did a talk about docker I also wanted to show a bit of what it does under the hood without going through all the layers and without too much details. This ~120 lines of shell script is really good in providing just an intro into what's needed for containers: https://github.com/p8952/bocker/blob/master/bocker

Latest Zen Kernel......
i tried it and like the concnpt, but until it can be launched via a systemd userspace service (without previously manually booting it) among other problems i will keep using docker (or bocker)

The Staff Engineer's Path – Book Review
> But you couldn't reimplement podman in a few hundred lines of code.
You don't even need a few hundred: https://github.com/p8952/bocker
And then there's 'dokku' which IIRC, started as a bash version of Heroku.
> Not all ideas have the same quality.
They really do. I've heard all kinds of things in my career, but almost none I would want to dedicate a portion of my life building. Not because they are bad ideas or won't work, but because of the person with the idea or it just didn't interest me. Those people went on to be moderately successful (like hundreds of millions worth) but I'm glad I wasn't on that ride.

“Implement DNS in a Weekend”
Bocker is in this same category...docker clone in bash that's helpful in seeing what's really happening underneath with nsenter, namespaces, network bridging, cgroups, etc.

Ask HN: What is the best source to learn Docker in 2023?
Docker implemented in around 100 lines of bash: https://github.com/p8952/bocker
This is the most mindblowing example for enterprise security teams that think Docker is a new threat on a single tenant Linux host.
No, buddies, all this stuff is already there. If you were fine with your visibility before*, you're still fine. Go find a real problem while we play with our developer dopamine.
* NARRATOR: They shouldn't have been.

Containers are chroot with a Marketing Budget
Bocker[1] does a reasonably good job of showing the value of Docker was mostly in Docker hub.

There is a cool project I've seen called "bocker" (https://github.com/p8952/bocker) which is something of a proof of concept of implementing Docker with bash, which speaks a bit to how Docker is indeed in many ways an amalgam of lower level primitives (such as chroot as you mentioned). Pretty neat!

Lazydocker
This does remind me of ctop as well: https://github.com/bcicen/ctop
It also let's you look at containers, resource usage graphs, their logs and even do some actions through a TUI.

Found an amazingly handy terminal UI for both docker and docker-compose. Have actually just added the bin to my git repo with all my compose files. Great for a quick look at what is going on host machines.
My problem with ctop is, that it seems to show wrong memory usage data: https://github.com/bcicen/ctop/issues/314

Portainer Alternatives?
When talk about interface and cli... I am a huge fan of ctop

What do you think about Portainer?
You can use CTOP. It's like a lite portainer on CLI. You can check logs, stats, restart containers.

Docker 2.0 went from $11M to $135M in 2 years
> I tried portainer, awful UX experience and all good features are inside paid version.
This is interesting to me, because it doesn't quite match my experience - I've been using Portainer for around 3 years at this point and it's been pretty decent.
The worst issues that I've gotten is networking issues in some hybrid configurations with Docker Swarm (e.g. Portainer cannot reach the manager node of the cluster for a bit), or troubles configuring Traefik ingresses when managing Kubernetes (though I think the recent patch notes talked about improving the ingress section, so maybe the experience will get better with non-Nginx ingresses).
Other than that, it's been great for onboarding new people, illustrating the cluster state at a glance, easily operating with stacks and scaling/restarting services as needed, including pulling new images, viewing the logs or even connecting to containers through a web UI if need be. The webhook functionality in particular is really nice - you can just do a curl request against a given URL and that will pull the new container versions for the given image and do a redeploy, which works nicely with a variety of CI solutions.
When I last tried, initializing Nomad clusters with networking encryption was a bit less of a smooth experience (needing to essentially manage your own PKI) and the web UI felt more like a dashboard, instead of something that you could click around in, if you're a proponent of that workflow.
Rancher is probably better than both of those options, though there's a certain overhead in regards to running both that software and a full Kubernetes cluster. If Kubernetes feels like a good fit for a particular project and resources aren't an issue, definitely check it out! You can, of course, also have some success with lightweight clusters, like K3s: https://k3s.io/
I'll definitely agree that Lazydocker is a nice tool, but I wouldn't call it superior, just different (TUI vs GUI), their demo video is nice though: https://youtu.be/NICqQPxwJWw
It actually reminds me of ctop, which you might also want to check out, though it's not something that you'd manage clusters in, merely the individual containers on a node (which won't always be enough, same as Docker Compose isn't): https://github.com/bcicen/ctop
Regardless, for Kubernetes, I'm inclined to say that you'd enjoy k9s a bunch then, it has a similar TUI approach: https://k9scli.io/
