This blog is created using the Zola static site engine. I use a combination of GitLab CI and
cron to automatically upload it to my web server whenever I merge a change to the Git
master branch of the home page.
elektrubadur.se source code is kept here in GitLab. While writing a post I just run
zola serve on my computer and can look at a dynamically updated website on a local web server.
Once ready, I commit on a branch and push it to GitLab, and then make a merge request. This might seem a bit silly for a one-man project, but this way I can disable pushes to the
master branch entirely, which can help prevent an accident.
The repository includes the separate repository web-build as a submodule. It contains some scripts used to build and publish the web site.
My website is hosted at HCoop, a hosting cooperative. Because it uses AFS, passwordless login requiers the use of Kerberos, so I can't just push the page using a deploy key.
So, rather than pushing the website there, I'm pulling. I've put the script
fetch_website.py from web-build on the target host, and makes it run it as a cron job:
*/5 * * * * k5start -qtUf "/etc/keytabs/user.daemon/$USER" -- "$HOME/scripts/fetch_website.py" "https://gitlab.com/bkhl/elektrubadur.se/-/jobs/artifacts/master/download?job=build" "$HOME/www/elektrubadur.se"
k5start thing is another thing needed because of the use of AFS and Kerberos. The point here is that you give the script a URL to a GitLab artifact, and a target directory, and it will deploy it if there's been any change.
The entire script is a bit long to post here, but it basically checks if there is a new artifact in GitLab for the website, built from the
master branch, and if there is downloads and deploys it. It saves the ETag in a file, so that it can compare to that and skip downloading unless there has been a change.
