For 15-20 years, I have run a script that gathers daily images for several comic strips. Recently, this script stopped working, and rather than fix it (it is Perl code that at this point has become unmaintainable) I decided to look for an OSS solution.
Web searches quickly led me to dosage.
Dosage can output HTML files, and it seems that, generally, people have Dosage output saved to a directory accessible on a web server. I wanted to do this too, but I also wanted to have this fully deployed via Ansible, and I wanted it to integrate with my Traefik server, with everything running in Docker images.
Also, there is an issue affecting Dosage's ability to download from GoComics, but there is also a workaround (posted in that thread) that is not yet available in the main Dosage code, so I wanted my Docker container to incorporate that fix.
I ended up with a very simple Docker container, a volume to store the images, and a cron job to run load the strips each day.
Credit for the download.sh script goes to Simon Szustkowski, in his dosage-docker repository.
I tried out Simon's image, but found that it was not suitable for my needs, due to the GoComics issue mentioned above. And, my solution is not a fork of his, but rather a similar solution.
The code to build my Dosage docker image is found here.
I'm using this as a one-shot container -- I do not leave it running.
The other side of this is having it on the web. Since I am already running Traefik, and since I only need to present a few files on the web, I decided to add this as another web server container connected to Traefik. Among other benefits, this means I easily get SSL using my existing configuration.
All I had to do on this side was to add another DNS entry (comics.unixdude.net), another call to my traefik-website role, and a little bit of configuration of that new role.
The only remaining pieces were to add a directory in which to store the images, and a cron job to run the dosage-docker container once daily.
