Master DevOps Tools with Real Practice

# Generate a plan and save it to a file
terraform plan -out=tfplan

# Review the output carefully:
# + means create
# ~ means modify in-place
# - means DESTROY (watch out!)
# -/+ means destroy and recreate

# Apply only the exact changes you reviewed
terraform apply tfplan

# Example output to watch for:
# aws_db_instance.main: Destroying... [id=mydb]
# ^ This line means your database is about to be deleted!
