container-structure-test is a testing tool from Google that verifies whether the structure of a built container image matches expectations. In a test file written in YAML, you specify conditions such as the output of particular commands, the existence, permissions, and contents of files, and metadata like environment variables or the entrypoint, and the tool runs or analyzes the image to check them. It is used to run image regression tests in CI after changing a Dockerfile.
validate the structure of your container images.
