OpenSCAP Container Compliance

• Utility for aiding in compliance checks against a container

Actuary

Packer

• Packer builds Docker containers without the use of Dockerfiles. By not using Dockerfiles, Packer is able to provision containers with portable scripts or configuration management systems that are not tied to Docker in any way. It also has a simple mental model: you provision containers much the same way you provision a normal virtualized or dedicated server.
