    A simple way to rebuild your web app container on every commit with local docker-compose and post-commit git hook


Initialize your git repo with git init
Place the attached post-commit file into .git/hooks/ directory and make it executable with chmod +x .git/hooks/post-commit
Use the attached docker-compose.yaml and Dockerfile as examples to create and run container
The .env file is not commited to VCS as it may contain secure configuration details. Put variables there like the following ones:

APPNAME=myapp
APPVERSION=latest


post-commit working directory is the repo root, it is the same one where .git is located
The post-commit script is Linux and MacOS compartible
Logs for building and running container is available in /tmp/git-post-commit as APPNAME-YYYYMMDD-HHMMSS-XXX files
