lsofer VS laravel-websockets-example

/proc is amazing once you get the hang of it and get a good understanding of what's all in there. Especially if you're doing low level performance tuning.

It's particularly helpful in larger infrastructures where tool the variability means differences in available tooling, and their output plus cli options. I'm sure /proc iteration has its own issues of variability across large infrastructres, but I haven't seen it. It's a fairly consistent API. Or at least it was, since I haven't touched a large infrastructure in some time.

When I got tired of `lsof` not being installed on hosts (or when its `-i` param isn't available) I ended up writing a script [1] that just iterates through /proc over ssh and grabs all inet sockets, environment variables, command line, etc from a set of hosts. Results in a null-delimited output that can then be fed into something like grafana to create network maps. Biggest problem with it is the use of pipes means all cores go to 100% for the few seconds it takes to run.

Oh yeah, bash functions are great and absolutely abusable. Sometimes you need some grand hacks to get it to work well, but when it works well, it can do some magic. You can even export functions over ssh!

I wrote this a few years back which ran on bunches of hosts and fed into a infrastructure network mapper based on each hosts' open network sockets to other known hosts. It wasn't really feasible to install a set of tools on random hosts.. but I still had root ssh access across the board. So I needed something tool agnostic, short, auditable, and effectively guaranteed to work:

I do the same thing, but slightly differently. https://github.com/francislavoie/laravel-websockets-example/...

I rather just write a bash script. It's the lowest common denominator. Make may not be installed by default in many places and it has some weird syntax quirks that make it annoying to use IMO.

Here's an example of how I like to do my "bash scripts that sorta work like make": https://github.com/francislavoie/laravel-websockets-example/... basically each function is a "command", so I do like "./utils start" or whatever.

This is an example repo I built a little while ago which outlines how I like to structure my Laravel projects for Docker: https://github.com/francislavoie/laravel-websockets-example

I wrote up my own version of what a docker stack looks like as an example repo a few months ago, I wanted to give Laravel Sail a spin but I found that it really wasn't that good; no path to transitioning to running on prod with that setup, no easy local HTTPS support, etc. Here it is: https://github.com/francislavoie/laravel-websockets-example
