Before you push your blog to the source branch, it should be tested.
Testing means:

• generating the static files with jekyll
• serving static pages with some webserver

It's definitely not enough if it looks good on github, or in your markdown editor.

Testing the blog

To locally test a new blog entry, follow these steps:

• Checkout the sequenceiq/blog-test github repo.
• Create a new post like source/_posts/2014-08-31-my-new-blog.markdown
• Create and run a blog-test container:

./blog-test.sh

Options:
  -d --dirty    don't stash uncommitted changed

It will:

• stash away uncommitted changes (unless -d is used)
• COPY the workdir to a new blog-test Docker image, at /tmp/blog
• RUN rake generate inside the container
• start the new Docker image, which will serve the public/blog on http
• stash back
• Automatically open a browser pointing to: http://192.168.59.103:8080/

Changing local port

In case your port 8080 is already occupied, you can change it:

export BLOG_PORT=9876
./blog-test.sh

Terminate the server

The blog server is started as a backround container. To clean up:

docker rm -f blog-test && docker rmi blog-test-image
