There’s a new Docker EE release available and it embraces Windows, Linux and Linux-based mainframe applications. Let’s see what’s new in Docker EE 17.06.

It’s been five months since Docker EE 17.03 was released and now 17.06 is here.

Docker’s a time-based release schedule

Just a friendly reminder: every Docker EE release is supported and maintained for one year and receives security and critical bug fixes during this period.

What’s new in Docker EE 17.06?

First, a video:

The 17.06 release puts Docker “further in the lead with the first Containers-as-a-Service (CaaS) solution in the market for the modernization of all applications without disruption to you and your IT environment,” Vivek Saraswat, Product Manager at Docker wrote in a blog post announcing the new release. “The new release embraces Windows, Linux and Linux-based mainframe applications. It includes UCP 2.2 and DTR 2.3 and establishes Docker EE as a key IT platform for both new application development as well as application modernization across both on-premises and cloud environments.”

Multi-architecture orchestration

Docker EE 17.06 includes new features such as:

  • Support for full lifecycle management of Docker Windows containers including image scanning, secrets management, and overlay networking
  • Integrate Windows and Linux applications through the use of overlay networking to support hybrid applications
  • Ability to intelligently orchestrate across mixed clusters of Windows, Linux, and mainframe worker nodes
  • With added support of Linux on IBM z Systems, Docker delivers a consistent experience (Compose files, networking, security, lifecycle management) across Linux, Windows, and Linux-on-mainframe applications

Secure multi-tenancy

Key new features include:

  • Leverage built-in default roles or create custom roles with granular permissions from the entire Docker API
  • Assign grants to users and teams for resource collections that include services, containers, volumes, networks, and secrets
  • Leverage RBAC for nodes to segment a team’s access to a specific set of nodes within a Docker EE environment

Policy-based automation

Key new features include:

  • Automatic image promotion using predefined policies to move images from one repository to another within the same registry
  • Immutable repositories prevent image tags from being modified or deleted, ensuring that production app repositories are secure and locked down
  • New APIs for:
    • Access control permissions
    • User / Team / Org management
    • Cluster configuration
