Scanning with CircleCI

Learn how to implement Endor Labs in a CircleCI pipeline.

CircleCI CI/CD pipelines allow you to configure your pipeline as code. Your entire CI/CD process is orchestrated through a single file called config.yml. The config.yml file is located in a folder called .circleci at the root of your project which defines the entire pipeline.

To integrate Endor Labs into your CircleCI CI/CD processes:

  1. Authenticate to Endor Labs
  2. Install your build toolchain
  3. Build your code
  4. Scan with Endor Labs

Authenticate to Endor Labs

Endor Labs recommends using keyless authentication in continuous integration environments. Keyless Authentication is more secure and reduces the cost of secret rotation but is only available on self-hosted runners in CircleCI.

To configure keyless authentication see the keyless authentication documentation

If you choose not to use keyless authentication you can configure an API key and secret in CircleCI for authentication using the following steps. See managing API keys for more information on generating an API key for Endor Labs.

  1. In your CircleCI environment, navigate to Organizational Settings.
  2. From Contexts and select Create Context.
  3. Enter a context name for reference such as endorlabs or re-use an existing context.
  4. Click into your new or existing context. Add any project restrictions and select Add Environment Variable.
  5. In Environment Variable Name, enter ENDOR_API_CREDENTIALS_KEY and in Value, enter the Endor Labs API Key.
  6. Select Add Environment Variable.
  7. Repeat the previous 3 steps to add your API key secret as the environment variable ENDOR_API_CREDENTIALS_SECRET. Have the name of the context handy to reference in the workflows later.

Configure your CircleCI pipeline

To create a CircleCI pipeline reference the following steps:

  1. Create a .cirlceci/config.yml file in your repository if you do not already have one.
  2. In your config.yml file customize the job configuration based on your project’s requirements using one of the examples, simple CircleCI configuration or advanced CircleCI configuration.
  3. Create two workflows called build_and_watch_endorlabs and build_and_test_endorlabs.
  4. Ensure that the context you created is part of the workflow if you are not using keyless authentication.
  5. Adjust the image field to conform to the required build tools for constructing your software packages, and synchronize your build steps with those of your project.
  6. Update your Endor Labs tenant namespace to the appropriate namespace for your project.
  7. Update your default branch from main if you do not use main as the default branch name.
  8. Modify any dependency or artifact caches to align with the languages and caches used by your project.

Examples

Use the following examples to get started. Make sure to customize this job with your specific build environment and build steps.

Advanced CircleCI configuration

The following example is an advanced implementation of Endor Labs in circleCI which includes several optional performance optimizations and job maintainability updates.

This includes:

  1. Caching and restoring caches of jobs and artifacts to improve performance. Caches should be modified to reflect the build artifacts and dependencies of your project.
  2. Segmenting jobs and scans.
