Jack's Blog

Versioned by Gitea, Built by Woodpecker, Rendered by Hugo, Stored in Minio, Cached by Nginx, Served by Traefik.

Building

Simply run $ hugo in the main directory (this will create a public/ folder with the web files)

Alternatively, use the Docker Image jacksgt/hugo (https://github.com/jacksgt/docker-hugo) which is used by the CI/CD server to render the blog.

The CI/CD server will run a build on each push, but only publish the artifacts of the master branch. To skip a CI build (i.e. not run an integration test for this specific commit, e.g. because I doesn't modify any content), use [CI SKIP] in the commit message.
