GitLab Pages deployment step fails after successfull build

Question

I am trying to host a reveal.js presentation via gitlab pages. The repository can be found here: https://gitlab.com/JanGregor/demo-slides

My .gitlab-ci.yml

Answer 1

From the GitLab Pages documentation:

To make use of GitLab Pages, the contents of .gitlab-ci.yml must follow the rules below:

1. A special job named pages must be defined
2. Any static content which will be served by GitLab Pages must be placed under a public/ directory
3. artifacts with a path to the public/ directory must be defined

Also mentioned (somewhat tangentially) in the "GitLab Pages from A to Z" guide:

... and GitLab Pages will only consider files in a directory called public.

Answer 2

Apparently a page can only be published from a folder in under the artifacts that is called "public".
