Configure Custom Domain
The default pages path is {GROUP}.gitlab.io/{PROJECT} or {/SUBGROUP/PROJECT} but the template used here is expecting to run at the root of the site.
For the example, I setup https://handbook.brownfield.dev to have the content deployed there.
To use the gitlab.io domain, adjust the first line of config.toml to reflect your subgroup and project paths as required.
Change the existing configuration:
baseURL = "https://handbook.brownfield.dev/"
to something like
baseURL = "https://brownfield-dev.gitlab.io/remote/handbook"
or
baseURL = "https://group.gitlab.io/handbook"
