bocker VS Tide

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.

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

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)

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.

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.

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.

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!

Rust has several, production ready, REST API frame works.

Rust allows me to mainly only run the application to confirm things work from a business perspective.

For people starting out building stuff in rust - understand that there is a distinction of async code and libraries and can lead to confusing compiler errors if you don't realize there is a distinction. It's simple in hindsight but did cause me to waste hours barking up the wrong trees at first. Other wise just learn about `match` and Result/Option types asap, they're fundamental.

https://github.com/http-rs/tide tide is great to create an http server / routes

https://github.com/djc/askama I use this to template out HTML and it checks all my boxes, dynamic data, passing in functions, control flow.

https://github.com/launchbadge/sqlx sql interface for a variety of backend, async safe.

https://github.com/seanmonstar/reqwest http client to make requests

Rust is amazing, don't let the initial few speed bumps discourage you - building real things with rust is no more challenging today than any other modern language stack.

Hi, guys, how you doing? I'm trying out this web framework Tide just to make a toy project and learn more about Rust. The create_payment_handler function is called by the framework whenever there is a POST request to /payment/ containing a JSON body with the payment information.

I'm developing the backend of https://www.cozydate.com/ in Rust. Async Rust is not productive yet, so I tried rouille http server which lets me write non-async request handlers. Unfortunately, it uses an unbounded thread pool and falls down under load https://github.com/tiny-http/tiny-http/issues/221 . Then I tried Tide and a threadpool to call my non-async API handlers. This worked, but was really ugly, and I had issues with uploads after deploying to Heroku https://github.com/http-rs/tide/issues/878 .

You could also habe a look at tide apparently it is stable and production ready.
