Cute Seal Fanpage

An experiment using Nix, Hakyll, Haskell, and shell scripts to automate a simple website deployment pipeline.

Why Seals?

It's an in-joke.

What's all this code?

seal-blog/

• devops/

  • build.sh

    • Uses a nix-shell expression to build the Hakyll executable

  • configuration.nix

    • The configuration file for the NixOS production server. This takes care of installing all the necessary software, setup Nginx, and get ACME certs for verification.

  • newSealPost.sh

    • Script to be called daily by a cron job on the server. Generates the post for the day, builds and commits.

• website/

  • A basic Hakyll site, slightly modified to serve seals. Most of the site is generated from the site.hs file. Check the Hakyll documentation for more info.

Work to be done

• The blog post generation and the hosting of the website are currently intertwined when they should be separated
  • Seal post generator just makes posts
  • Hakyll blog imports or calls the post generator
  • The deployed server/nix config file has a cron job for adding a new blog and committing every day
• Need to move the blog and post generation inside nixos-apps on my beefier server
  • The configuration file here is for it's own Linode, the current small one running, but I have a better setup for that now
  • Pull out the useful parts for my deployed server, remove anything not necessary for a small config file
  • Also switch to using caddy if not already
• Experiment with * A records
  • For the seal blog
  • Instead of having www and git and ... subdomains spelled out in Namecheap
  • Just have a * record and have caddy do the filtering
