Git Branching Diagram Template for diagrams.net

This is my own variant of a git branching diagram template based on Bryan Braun's great template.

You can use this diagram as a template to create your own git branching diagrams. Here's how:

1. Create a new diagram with diagrams.net (formerly draw.io)
2. Go to File > Open From > URL
3. Insert this url (it points to the xml data below): https://gist.githubusercontent.com/dornfeder/13abff279de357f048e474d4ed6c692d/raw/f5efc838bd34429e59e38063bd348b7a86457d18/git-diagram-template.xml
4. Customize as needed for your team.

How to quickly run postgres (using docker)

docker run --network="host" -it --rm --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -e PGDATA=/var/lib/postgresql/data/pgdata -v /tmp/pgdata2:/var/lib/postgresql/data -e POSTGRES_USER=test postgres

This command will quickly start postgres on port 5432 and create a database test with user test and password mysecretpassword
