tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

Howdy Y'all! I'm @kordless on YouTube and I occasionally play and stream Rust, the game.

This repo is for deploying a Rust Server running on Google Container Engine. Google has a deal going where you can get $300 of free credits for a year on Google Cloud, so it's a good excuse to signup and run your own server. And no, I don't work for Google!

based on this article https://www.rustafied.com/how-to-host-a-rust-server-in-linux

This deployment origionally used an image built by @dids, which is hosted on Docker Hub: https://hub.docker.com/r/didstopia/rust-server/

This deployment method can be used to start a small server to play with friends or practice building things. In a few days, I'll update the scripts to include a way to save the content you've created, in-game, with others who can then run their own servers and load your content in to explore it for themselves.
