Git workflow questions

Hi, what would be the correct workflow to do a git pull since i am having some sites developed at github and pulled to site with webhook

since you now do docker containers i am not so familiar with them…

before editing was as simple as this for example -
now the path is all wrong (echo $PWD’) shows real path and the git binary is missing…

sorry for n00b questions… thanks

there is an actual pull req i just found out -
