You can build the container that wraps the docker-bench for security:
|

|
||||
```sh
|

✗ git clone git@github.com:docker/docker-bench-security.git
|

✗ cd docker-bench-security

✗ docker build -t docker-bench-security .

cd docker-bench-security

docker build -t docker-bench-security .

The Docker Bench has the main script called `docker-bench-security.sh`.

This is the main script that checks for all the dependencies, deals with

command line arguments and loads all the tests.

The tests are split in 6 different files:
