## Project history and usage

Container Structure Tests is a GoogleContainerTools project for validating container image contents, command behavior, filesystem state, and metadata. It became a common package-manager entry because it is a standalone binary aimed at CI checks for built images.

### Project history

The project released v0.1.0 in October 2017 and v1.0.0 in March 2018. Its README now describes the project as not officially supported by Google and in maintenance mode, while still accepting contributions.

### Adoption history

Official documentation emphasizes local binary use, Docker-image use, and Google Cloud Builder use. It also documents Homebrew installation for macOS, which helped make the CLI easy to install outside a larger Google Cloud SDK.

### How it is used

Users provide YAML or JSON test files to `container-structure-test test --image ... --config ...`. The test types cover command output, file existence, file contents, image metadata, and license checks, which are the concerns image publishers usually want to verify before release.

### Why package nerds care

The package matters because it made container image assertions portable: the test spec can live beside a Dockerfile, and CI can fail the image artifact rather than only failing application unit tests. Its explicit schema versioning and single-purpose binary made it attractive to packaging and release pipelines.

### Timeline

- 2017: v0.1.0 release published.
- 2018: v1.0.0 release published.
- 2025: v1.22.1 release published while the README described the project as in maintenance mode.

### Related projects

- The README references Docker, Google Cloud Builder, and container image metadata rather than a specific runtime integration.
