Example that demonstrates how to test container images with various tools.

Testing Container Images

This sample project shows how to test container images with different tools:

• Bash Automated Testing System
• Goss
• Serverspec
• Testcontainers with JBang
• Testinfra

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).
