This document describes how to use the instance update feature on Engine Yard.

This might be a good solution for you if you have multiple app servers and periodically, due to instance timeout errors, the Chef run completes on some but not all of the instances. Using this feature, you can re-apply Chef to the instance that needs it (that is, it shows a red status in the dashboard).

Note: There are cases where, should that apply go green, it will trigger a quick run.

Use instance update

Important: We recommend testing in a staging environment before applying changes in a production environment.

To update an individual instance

  1. Log in to your Engine Yard account.
  2. Navigate to the environment by clicking on the environment name in the dashboard.
  3. On the Environment page, determine which specific instance needs a Chef update.

    For example, when you apply Chef updates to your environment, sometimes not all instance updates complete successfully. The most common reason for this is a connection timeout at the infrastructure level.

  4. Click Apply at the individual instance level.

    Engine Yard applies the Chef configuration updates to the individual instance.

    The dashboard indicator should turn green to indicate success. If not, check your configuration logs and see More information.

    If you are still having trouble, submit a ticket with Engine Yard Support.
