Recently I decided to host my personal portfolio site using GitHub pages. Even though they have very detailed instruction on how to setup a custom domain, I found it cumbersome to get to the right information. ?
Here are 2 key steps to setup your GitHub pages enabled project to use your custom domain.
??Step 1 ? Set domain in GitHub project
Go to your GitHub Pages site?s repository settings. Under ?Custom domain?, add or remove your custom domain and click ?Save?.
Setting ?custom domain? creates a file named CNAME in the same repository. Don?t delete it.
??Step 2 ? Set custom resource record for domain
This step is specific to your domain name register (like GoDaddy, Domain.com, Google Domains, etc). All you need to do is set A & CNAME records for the selected domain.
This is a sample screenshot taken from the Google Domains portal.
For A record, set 188.8.131.52, 184.108.40.206, 220.127.116.11 and 18.104.22.168. To redirect www subdomain to the original domain, add a CNAME record with your GitHub pages profile URL with a .(dot) in the end, for example, ?YOUR-GITHUB-USERNAME.github.io.?.
Official References: For most up to date IP Addresses, use GitHub?s official documentation and for setting up CNAME use this documentation.
That?s it, both www.your-domain.com and your-domain.com will now go to your selected GitHub pages site (may need to wait up to 24 hours). If you want to see a live example, you may visit my portfolio ?hossainkhan.com? hosted via GitHub pages repository ??.
UPDATE #1: The IP addresses for DNS A record is updated. The new IP addresses are required to use the free HTTPS support for GitHub pages.
UPDATE #2: Some people said this change is not working, it is actually because the DNS update can take upto 24 hours to propagate. So, I guess try hitting your domain next day ?
NOTE #1: Even though it?s very obvious, you should replace YOUR-GITHUB-USERNAME and your-domain.com with your personal github username and domain name you are trying to use respectively.
