When I write Apache APISIX-related blog posts, I want my colleagues to review them first. However, it’s my blog, and since I mix personal and business posts, I want to keep them from the repository. I need a preview, accessible only to a few, something like Vercel’s preview. I’m using GitLab Pages, and there’s no such out-of-the-box feature. I tried two methods: GitHub gists and PDFs. Both have issues. Gists don’t display as nicely as the final page.
