Secure Engine

This section discusses the security features you can configure and use within your Docker Engine installation.

• You can configure Docker’s trust features so that your users can push and pull trusted images. To learn how to do this, see Use trusted images in this section.

• You can protect the Docker daemon socket and ensure only trusted Docker client connections. For more information, Protect the Docker daemon socket

• You can use certificate-based client-server authentication to verify a Docker daemon has the rights to access images on a registry. For more information, see Using certificates for repository client verification.

• You can configure secure computing mode (Seccomp) policies to secure system calls in a container. For more information, see Seccomp security profiles for Docker.

• An AppArmor profile for Docker is installed with the official .deb packages. For information about this profile and overriding it, see AppArmor security profiles for Docker.

• You can map the root user in the containers to a non-root user. See Isolate containers with a user namespace.

• You can also run the Docker daemon as a non-root user. See Run the Docker daemon as a non-root user (Rootless mode).
