DNS Configuration: Google Domains and Jekyll @ github.io

The setup and configuration process for a Domain managed by Google Domains running a Jekyll Blog hosted on GitHub Pages.

---

Step 1 – Fork and update a GitHub repo.

• I forked this quickstart Jekyll now repo, by Barry Clark.
• Inside your fork, rename the repo using the following format {githubusername}.github.io
• In the settings section of the repo, goto the GitHub Pages section and point it to your naked domain, IE: http://example.com – without the www. canonical name alias.
• Update the CNAME file in the root directory, as follows:

example.com
www.example.com

That is all it takes to configure your blog in GitHub. Now you will need to configure the domain itself.

---

Step 2 – Configure the DNS records for your domain.

Login to Google Domains and navigate to the DNS configuration section of the domain you wish to configure.

• Custom resource records:

Name	Type	Time To Live	Data
@	A	1H	192.30.252.153
			192.30.252.154
www	CNAME	1H	{githubusername}.github.io

That’s all… but be warned that it may take a bit to propagate the records across the globe ( up to a day ), but generally this happens in less than 5 minutes for most locations.

You can visual the propagation using various online tools while you wait.
