A bash script to create a Git post-receive hook to deploy after a Git push
#!/bin/bash
# Call this file with `bash ./project-create.sh project-name [service-name]`
# - project-name is mandatory
# - service-name is optional
# This will creates 4 directories and a git `post-receive` hook.
# The 4 directories are:
# - $GIT: a git repo
# - $TMP: a temporary directory for deployment
# - $WWW: a directory for the actual production files
# - $ENV: a directory for the env variables
# When you push your code to the git repo,
# the `post-receive` hook will deploy the code
# in the $TMP directory, then copy it to $WWW.
DIR_TMP="/srv/tmp/"
DIR_WWW="/srv/www/"
DIR_GIT="/srv/git/"
DIR_ENV="/srv/env/"
