How to Delete an EC2 Created Outside of Duplo

This guide explains how to delete an EC2 instance that was created manually outside the DuploCloud platform. By default, the DuploCloud admin IAM ( duplomaster ) role only allows termination of EC2 instances that have a TENANT_NAME tag. Prerequisites: You must have Just-In-Time (JIT) admin access to the AWS Console. See: Just-in-Time (JIT) Access in the DuploCloud docs for full details. Steps:

1. Get JIT Access to AWS Console Use DuploCloud’s CLI to launch an admin session in the AWS console: duplo-jit aws --admin --host "https://.duplocloud.net" --interactive | jq -r .ConsoleUrl | pbcopy Open the copied URL in your browser.

2. Find the EC2 instance In the AWS Console:

• Go to EC2 > Instances

• Identify the instance you want to delete

1. Tag the instance Select the instance Click “Tags” then “Manage Tags” Add the following tag: Key: TENANT_NAME Value: deleteme

2. Terminate the instance

• With the tag in place, select the instance

• Click “Instance state” → “Terminate instance”

• Confirm Once the TENANT_NAME tag is present, the DuploCloud IAM policy allows deletion.
