DNSControl and Github Actions #100daysofhomelab
I am participating in the #100daysofhomelab challenge and have been posting a lot on Twitter as @tiernano, but some posts and tasks I am doing will require longer-form write-ups. So, some updates will include either Videos (which will be published on my Youtube Channel) or blog posts, which will go here. This is the first of the blob posts.
DNSControl is a tool written by the Stackoverflow lads (when they called themselves StackExchange). It is designed to update DNS records and can work with DNS providers and registrars. I use it to update records in Cloudflare and Route53, but many providers are available. I wrote an article a while back about how to create reverse DNS records for IP space with Route53 and DNSControl, but most of it is still relevant, and the main documentation site for DNSControl has a lot of useful tips.
Up till this morning, if I wanted to update a record, I checked out the DNS records from my private Github repo, made the change, and ran the DNSControl commands on my machine (check for syntax checking the file, preview to show what will change at the provider level, and push to make the changes). But I wanted to have some automation for this. So, enter Github Actions.
