This document describes the latest changes, additions, known issues, and fixes for Docker Enterprise Edition (Docker EE).

Docker EE is functionally equivalent to the corresponding Docker CE that it references. However, Docker EE also includes back-ported fixes (security-related and priority defects) from the open source. It incorporates defect fixes that you can use in environments where new features cannot be adopted as quickly for consistency and compatibility reasons.

  • Docker EE 17.06.2-ee-5 now enables the telemetry plugin by default on all supported Linux distributions. For more details, including how to opt out, see the documentation.

Client

Logging

Networking

Packaging

  • Add telemetry plugin for all linux distributions
  • Fix install of docker-ee on RHEL7 s390x by removing dependency on container-selinux

Runtime

  • Add support for Windows version filtering on pull of docker image moby/moby#35090

Swarm mode

  • Increase gRPC request timeout to 20 seconds for sending snapshots to prevent context deadline exceeded errors docker/swarmkit#2391
  • When a node is removed, delete all of its attachment tasks so networks used by those tasks can be removed docker/swarmkit#2414

Known issues

  • It's recommended that users create overlay networks with /24 blocks (the default) of 256 IP addresses when networks are used by services created using VIP-based endpoint-mode (the default). This is because of limitations with Docker Swarm moby/moby#30820. Users should not work around this by increasing the IP block size. To work around this limitation, either use dnsrr endpoint-mode or use multiple smaller overlay networks.
  • Docker may experience IP exhaustion if many tasks are assigned to a single overlay network, for example if many services are attached to that network or because services on the network are scaled to many replicas. The problem may also manifest when tasks are rescheduled because of node failures. In case of node failure, Docker currently waits 24h to release overlay IP addresses. The problem can be diagnosed by looking for failed to allocate network IP for task messages in the Docker logs.
  • SELinux enablement is not supported for containers on IBM Z on RHEL because of missing Red Hat package.

Known issues

If a container is spawned on node A, using the same IP of a container destroyed on nodeB within 5 min from the time that it exit, the container on node A is not reachable until one of these 2 conditions happens:

  1. Container on A sends a packet out,
  2. The timer that cleans the arp entry in the overlay namespace is triggered (around 5 minutes).

As a workaround, send at least a packet out from each container like (ping, GARP, etc).
