BuildKit has built-in support for analyzing your build configuration based on a
set of pre-defined rules for enforcing Dockerfile and building best practices.
Adhering to these rules helps avoid errors and ensures good readability of your
Dockerfile.
Checks run as a build invocation, but instead of producing a build output, it
performs a series of checks to validate that your build doesn't violate any of
the rules. To run a check, use the `--check` flag:
```console
$ docker build --check .
```
To learn more about how to use build checks, see
[Checking your build configuration](https://docs.docker.com/build/checks/).
