So one day I get unknown revision error after running go get command from private repo

The easiest solution is to just add alias to force to use ssh (so credential will use our underlying ~/.ssh)

[url "ssh://git@theprivaterepo.com:2222/"]
	insteadOf = https://theprivaterepo.com/

Some recomend to use .netrc or use git credential provider

Using ffmpeg for windows from gyan.dev at https://www.gyan.dev/ffmpeg/builds/, it is executed in WSL shell (in case you are wondering with all the shell syntax - for cmd or PowerShell just change it to windows path)

If you manage it everyday - add this to your .basrc or .bash_profile or cloud-console. If not then all k in this cheatsheet means kubectl

alias k="kubectl"
