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.
[1] https://github.com/p8952/bocker
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!

Runtipi: Docker-Based Home Server Management
> Any tips on the minimum hardware or VPS's needed to get a small swarm cluster setup?
From my testing, Docker Swarm is very lightweight, uses less memory than both Hashicorp Nomad and lightweight Kubernetes distros (like K3s). Most of the resource requirements will depend on what containers you actually want to run on the nodes.
You might build a cluster from a bunch of Raspberry Pis, some old OptiPlex boxes or laptops, or whatever you have laying around and it's mostly going to be okay. On a practical level, anything with 1-2 CPU cores and 4 GB of RAM will be okay for running any actually useful software, like a web server/reverse proxy, some databases (PostgreSQL/MySQL/MariaDB), as well as either something for a back end or some pre-packaged software, like Nextcloud.
So, even 5$/month VPSes are more than suitable, even from some of the more cheap hosts like Hetzner or Contabo (though the latter has a bad rep for limited/no support).
That said, you might also want to look at something like Portainer for a nice web based UI, for administering the cluster more easily, it really helps with discoverability and also gives you redeploy web hooks, to make CI easier: https://www.portainer.io/ (works for both Docker Swarm as well as Kubernetes, except the Kubernetes ingress control was a little bit clunky with Traefik instead of Nginx)

Setup Portainer for Server App
In this section, we will add Portainer to help us in managing our Docker containers. You can find more details about it here. To integrate Portainer into our EC2 project, we can follow these steps:
-
Old documentation url on Github issues gives ERR_TOO_MANY_REDIRECTS.
Git issues pointing to: https://docs.portainer.io/v/ce-2.9/start/install/agent/swarm/linux gives a ERR_TOO_MANY_REDIRECTS.

Docker CI/CD with multiple docker-compose files.
I am currently running Portainer, but webhooks (GitOps) appear to be broken ( [2.19.0] GitOps Updates not automatically polling from git · Issue #10309 · portainer/portainer · GitHub ) and so I cannot send webhook to redeploy a stack. So, looking for alternatives. Using this as a good excuse to learn more about docker and CI/CD etc.

Ask HN: How do you manage your “family data warehouse”?
A Synology NAS running Portainer (https://www.portainer.io/) running Paperless NGX (https://github.com/paperless-ngx/paperless-ngx)
This works better than I can possibly tell you.
I have an Epson WorkForce ES-580W that I bought when my mother passed away to bulk scan documents and it scans everything, double-sided if required, multi-page PDFs if required, at very high speed and uploads everything to OneDrive, at which point I drag and drop everything into Paperless.
I could, thinking about it, have the scanner email stuff to Paperless. Might investigate that today.
Paperless will OCR it and make it all searchable. This setup is amazing, I love living in the future.

Bare-Metal Kubernetes, Part I: Talos on Hetzner
> I've come to the conclusion (after trying kops, kubespray, kubeadm, kubeone, GKE, EKS) that if you're looking for < 100 node cluster, docker swarm should suffice. Easier to setup, maintain and upgrade.
Personally, I'd also consider throwing Portainer in there, which gives you both a nice way to interact with the cluster, as well as things like webhooks: https://www.portainer.io/
With something like Apache, Nginx, Caddy or something else acting as your "ingress" (taking care of TLS, reverse proxy, headers, rate limits, sometimes mTLS etc.) it's a surprisingly simple setup, at least for simple architectures.
-
What are some of your fav panels and why?
casaos it just makes things like backups, offsite syncing and many other nas related things so much easier to manage. And gives you a proper nas like experience similar to that in which you'd fine on companies like tnas or synology. I actually also use it as a replacement for portainer when i don't need the more advanced features it offers

Kubernetes Exposed: One YAML Away from Disaster
> I moved to docker swarm and love it. It's so much easier, straight forward, automatic ingress network and failover were all working out of the box. I'll stay with swarm for now.
I've had decent luck in the past with the K3s distribution, which is a bit cut down Kubernetes: https://k3s.io/
It also integrates nicely with Portainer (aside from occasional Traefik ingress weirdness sometimes), which I already use for Swarm and would suggest to anyone that wants a nice web based UI: https://www.portainer.io/
Others might also mention K0s, MicroK8s or others - there's lots of options there. But even so, I still run Docker Swarm for most of my private stuff as well and it's a breeze.
For my needs, it has just the right amount of abstractions: stacks with services that use networks and can have some storage in the form of volumes or bind mounts. Configuration in the form of environment variables and/or mounted files (or secrets), some deployment constraints and dependencies sometimes, some health checks and restart policies, as well as resource limits.
If I need a mail server, then I just have a container that binds to the ports (even low port numbers) that I need and configure it. If I need a web server, then I can just run Apache/Nginx/Caddy and use more or less 1:1 configuration files that I'd use when setting up either outside of containers, but with the added benefit of being able to refer to other apps by their service names (or aliases, if they have underscores in the names, which sometimes isn't liked).
At a certain scale, it's dead simple to use - no need for PVs and PVCs, no need for Ingress and Service abstractions, or lots and lots of templating that Helm charts would have (although those are nice in other ways).
