Real life examples

By default, all images will uses production version of components (library and agent). You can use a specific version of a component by adding it inside binaries/ (documentation). The main idea behind this behavior is to test a specific version against production version of other components.

Environement variables

You can define your setup in environment variable in a .env file. Here is the mapping:

  • <library_name> => TEST_LIBRARY
  • -i/--images => BUILD_IMAGES
  • -w/--weblog-variant => WEBLOG_VARIANT

Authentication for pulling images

Some images are hosted at Github. Those images require authentication.

If you find an error messages like:

Error response from daemon: Head "https://ghcr.io/v2/datadog/system-tests-apps-ruby/rails70/manifests/latest": unauthorized

You have to make to sure to authenticate before pulling the images.

  1. Create a Github token. The token has to have package read and write perimssions. You can create the token using this link: https://github.com/settings/tokens/new?scopes=write:packages
  2. Make sure to enable SSO for the new token.
  3. Authenticate docker: 3.1 docker login ghcr.io 3.2 paste your Github username 3.2 paste the token string from step 1.
