Set up Atlantis to automate Terraform plan and apply through GitHub pull requests, giving every team member a safe, auditable way to change infrastructure.

Explore

Importing Existing Infrastructure into Terraform State

Import AWS resources created manually or outside Terraform into your state file so Terraform can manage them going forward without recreating them.

Explore

Provisioning AWS Infrastructure with Terraform — VPC, EC2, S3, and RDS

Provision a production-ready AWS infrastructure stack with Terraform — VPC, subnets, security groups, EC2 instances, S3 buckets, and RDS databases.

Explore

Terraform CI/CD — Automating Plan and Apply with GitHub Actions

Automate Terraform with GitHub Actions — running terraform plan on pull requests and terraform apply on merge, with OIDC authentication and PR comments.

Explore

Terraform Data Sources — Reading Existing Infrastructure Without Managing It

Use Terraform data sources to read existing cloud resources — fetching AMI IDs, VPC details, and secrets without importing them into your state file.

Explore

Terraform Drift Detection — Finding and Fixing Infrastructure That Changed

Detect and fix infrastructure drift — when someone changes a resource in the AWS console and your Terraform state no longer matches reality.

Explore

Terraform HCL — Variables, Outputs, Locals, and Expressions Explained

Master Terraform HCL syntax — writing reusable variables, capturing outputs, using locals for calculations, and writing expressions and conditionals.

Explore

Terraform Registry — Using Community Modules and Publishing Your Own
