Hey there! Let’s talk about Terraform, okay? This awesome tool helps you manage infrastructure like a pro, all in code. It’s super versatile and works with tons of different providers. Cool, right?
So, first things first: you write these config files to lay out what you want your infrastructure to look like. You can have servers, databases, networks – you name it!
Then, you kick things off with terraform. That gets everything set up and grabs any plugins you might need. Next up, you run terra plan. This gives you a sneak peek at what Terraform gonna do based on your config files.
When you’re ready to make it happen, hit terraform apply. That’s where the magic really starts. Terraform goes to work creating, updating, or getting rid of resources to match your config.
And don’t forget about state management! Terraform keeps track of everything in a file called terraform.tfstate. It links your config to the real stuff out there in the world so everything stays shipshape and consistent. So handy!
