This sample project shows how to test container images with different tools:
Each sample performs the same tests on myimage (Dockerfile), if supported:
- Testing that nginx is installed.
- Ensuring that nginx workers do not run as root.
- Testing that nginx is properly exposed and serves a welcome page by checking it on the host.
- Checking that the container only exposes port 80 by default by inspecting the image configuration.
While the whole sample is obviously contrived, it gives a good idea of the capabilities of each tool and shows how to use them (see workflows).
