How to Auto Approve Terraform Apply Commands Easily

To auto approve a Terraform apply, use the -auto-approve flag with the terraform apply command. This skips the interactive approval prompt and applies changes immediately.

Syntax

The terraform apply command applies changes to your infrastructure. Adding the -auto-approve flag skips the confirmation prompt, allowing the command to run without manual input.

• terraform apply: Starts the apply process.
• -auto-approve: Automatically approves the plan without asking.

bash

terraform apply -auto-approve

Example

Common Pitfalls

Using -auto-approve can be risky because it applies changes immediately without review. Common mistakes include:

• Running terraform apply -auto-approve without checking the plan first.
• Applying destructive changes unintentionally.
• Using auto-approve in production without safeguards.

Always run terraform plan first to review changes before auto approving.

bash

terraform apply
# waits for user confirmation

# Wrong: skipping plan and auto approving blindly
terraform apply -auto-approve

# Right: plan first, then auto approve
