AppArmor security profiles for Docker -------------------------------------- AppArmor (Application Armor) is a security module that allows a system administrator to associate a security profile with each program. Docker expects to find an AppArmor policy loaded and enforced. Container profiles are loaded automatically by Docker. A profile for the Docker Engine itself also exists and is installed with the official *.deb* packages. Advanced users and package managers may find the profile for */usr/bin/docker* underneath [contrib/apparmor](https://github.com/docker/docker/tree/master/contrib/apparmor) in the Docker Engine source repository. Understand the policies ------------------------ The `docker-default` profile the default for running containers. It is moderately protective while providing wide application compatability. The system's standard `unconfined` profile inherits all system-wide policies, applying path-based policies intended for the host system inside of containers. This was the default for privileged containers prior to Docker 1.8. Overriding the profile for a container --------------------------------------- Users may override the AppArmor profile using the `security-opt` option (per-container). For example, the following explicitly specifies the default policy: ``` $ docker run --rm -it --security-opt apparmor:docker-default hello-world ```
