- the engine of Docker Enterprise Edition will run on Linux on z Systems
- Docker Trusted Registry (DTR) can handle s390x images (while DTR runs on x86)
- Docker Universal Control Plane (UCP) can manage s390x nodes (while the UCP UI runs on x86)
The engine of Docker Enterprise Edition is a commercially supported by Docker, Inc for the enterprise distros of the Linux distribution partners we closely work with. A previous blog post has discussed support timelines of CE and EE. This adds Docker, Inc. as another support provider when for running a container environment on IBM Z.
After installation ("install as you would on x86"), it's a plain Docker engine that runs on Z.
Docker Trusted Registry provides a commercially supported registry environment. It offers features like a web user interface to inspect and manage repositories in a registry server. Access can be controlled and organized in teams. Note that security scanning does not know about s390x vulnerabilities at this time. Here are a few screenshots showing functionality:
Docker Universal Control Plane is a management tool for working in a Docker swarm cluster. It handles s390x nodes in a swarm, and operates the swarm: it allows to manage the life cycle of containers and services in the cluster and can deal with associated resources such as networks, volumes and secrets. Here are a few screenshots showing the look and feel:
To use with s390x nodes, simply add these nodes in the "Nodes" mask -- it is a simple docker swarm join command on z nodes, run against the swarm manager running on x86.
