Full Description

Docker Bench for Security

The Docker Bench for Security is a script that checks for dozens of common
best-practices around deploying Docker containers in production. The tests are
all automated, and are inspired by the CIS Docker Community Edition Benchmark v1.1.0.
We are releasing this as a follow-up to our Understanding Docker Security and Best Practices
blog post.

We are making this available as an open-source utility so the Docker community
can have an easy way to self-assess their hosts and docker containers against
this benchmark.

Running Docker Bench for Security

We packaged docker bench as a small container for your convenience. Note that
this container is being run with a lot of privilege -- sharing the host's
filesystem, pid and network namespaces, due to portions of the benchmark
applying to the running host. Don't forget to adjust the shared volumes
according to your operating system, for example it might not use systemd.

The easiest way to run your hosts against the Docker Bench for Security is by
running our pre-built container:

docker run -it --net host --pid host --userns host --cap-add audit_control \
    -e DOCKER_CONTENT_TRUST=$DOCKER_CONTENT_TRUST \
    -v /var/lib:/var/lib \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /usr/lib/systemd:/usr/lib/systemd \
    -v /etc:/etc --label docker_bench_security \
    docker/docker-bench-security

Docker bench requires Docker 1.13.0 or later in order to run.

Note that when distributions doesn't contain auditctl, the audit tests will
check /etc/audit/audit.rules to see if a rule is present instead.

Distribution specific Dockerfiles that fixes this issue are available in the
distros directory.

The distribution specific Dockerfiles
may also help if the distribution you're using haven't yet shipped Docker
version 1.10.0 or later.

Building Docker Bench for Security

If you wish to build and run this container yourself, you can follow the
following steps:

git clone https://github.com/docker/docker-bench-security.git
cd docker-bench-security
docker build -t docker-bench-security .
docker run -it --net host --pid host --cap-add audit_control \
    -e DOCKER_CONTENT_TRUST=$DOCKER_CONTENT_TRUST \
    -v /var/lib:/var/lib \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /usr/lib/systemd:/usr/lib/systemd \
    -v /etc:/etc --label docker_bench_security \
    docker-bench-security

or use Docker Compose:

git clone https://github.com/docker/docker-bench-security.git
cd docker-bench-security
docker-compose run --rm docker-bench-security

Also, this script can also be simply run from your base host by running:

git clone https://github.com/docker/docker-bench-security.git
cd docker-bench-security
sudo sh docker-bench-security.sh

This script was built to be POSIX 2004 compliant, so it should be portable
across any Unix platform.
