Real people Β· Real resultsβI've used many other sites to learn Linux, and while they were helpful, DevOpsPath really solidified my understanding. Coming from a linguistics background with some front-end experience, the hands-on approach made complex concepts finally click.β

Workspaces let you run the same Terraform config against dev, staging, and prod with separate state files.
# Create and switch between workspaces
terraform workspace new dev
terraform workspace new staging
terraform workspace new prod
terraform workspace select staging
terraform workspace list
# Use workspace name in configuration
resource "aws_instance" "web" {
ami = var.ami_id # Use a variable or data source for your region
instance_type = terraform.workspace == "prod" ? "t3.large" : "t3.micro"
tags = {
Name = "web-${terraform.workspace}"
Environment = terraform.workspace
}
}
# Each workspace has its own state file
# dev -> terraform.tfstate.d/dev/terraform.tfstate
# staging -> terraform.tfstate.d/staging/terraform.tfstate
# prod -> terraform.tfstate.d/prod/terraform.tfstateQuick Start
