Playing with git hooks
09 Dec 2015 by Friedrich Ewald · 1 min readGit scm offers a very interesting technique, called hooks. A hook is basically a trigger which is fired after the specific event occurs. If you create a new git repository with git init the folder .git/hooks with a couple of sample shell scripts is created. I personally use a hook to automate the deployment process of this website. After a commit is made, I automatically run a jekyll build and then copy the newly created site to the server.
My current post-commit script looks like the following, simple but effective:
#!/bin/bash
jekyll build
scp -r _site/* [email protected]:/home/user/html/
##Update 2015-12-11
I slightly changed the deploy script to only update changed files because I realized that the time to update the homepage will increase with every posting. For this reason I had to use rsync. Now the scripts looks as follows:
#!/bin/bash
jekyll build
rsync --update --progress -r _site/* [email protected]:/home/user/html/
The easiest way to synchronize over SSH is with a certificate.
