Today has been a mixed bag of stuff. For the next two weeks you can find the stream on my twitch channel.

Automated updates: Created a quick post-receive hook to update the site when git-annex syncs:

#!/usr/bin/env ruby

require "open3"

pushed_refs = $stdin.readlines

output, status = Open3.capture2e("git annex post-receive", stdin_data: pushed_refs.join("\n"))

system("bundle config set path /srv/")
system("bundle install")
system("JEKYLL_ENV=production bundle exec jekyll build --strict --trace --destination /srv/ --verbose --incremental")

This does the git annex post-receive default updates which (I assume) put all the files in place. Afterwards it configures the gem cache, installs the bundle, and runs a incremental site build.

On my tests with git annex sync --content this worked fine and updated the test site with the new files.

Public test site: I’ve also puttered around with adding a new site to host the in-progress work, but screwed up the DNS configuration and am still waiting on Let’s Encrypt’s verification systems to refresh their cache. Luckily this refresh happened while I was still here, so is now deployed and secured. See the following commits for some more tweaking required to get it working. The actual private keys are deployed through a separate private repo that is not shared.

Persistent SSH hostkeys: Finally I’ve added some code to the Dockerfile to preserve ssh host keys across rebuilds. The keys, again, are stored outside the published repo. Without this change, everytime a new version of the docker container is started, it would give nasty errors about the SSH host keys being changed.
