New Feature: Custom Hooks

We’re happy to announce custom hooks that make it easier to customize your Terraform workflow while using Scalr as the remote backend.

Ryan Fee

Director - Solution Architecture

Scalr makes it easier to automate and collaborate with your colleagues, but we recognize that different organizations and teams might have unique workflows, which is why we have now added the custom hooks feature within workspaces.

Problem

Normally, users are accustomed to running Terraform from their laptop or an environment where they have the freedom to have a completely custom runtime environment. When running Terraform in a remote backend, you are restricted to what is already installed in that environment … until now.

Solution

Custom hooks allow you to execute any command you would normally run in a Linux command line before and/or after the plan and before and/or after the apply. Common use cases are:

  • Executing tools (tflint, checkov, etc) before a plan to run lint or security tests
  • Pulling the plan JSON and uploading it to a third party system
  • Install software needed as part of your Terraform run before the plan or apply
  • Triggering API calls to a third party (Slack, Teams, etc) after the run has successfully completed.

Here is what it looks like in the workspace settings:

How to Get Started

To try the hooks out, go to the settings of any one of your workspaces where you will find the custom hooks section. As seen in the screenshot above, just enter in your standard commands, which are passed to the runtime environment and executed as part of the run. The output can be found in the plan and apply output:
