Docker v1.12.2-RC2 发布了。Docker1.12通过swarm实现了容器集群，在集群之上可以service命令创建一个服务，实现服务的多实例。在服务之上，通过stack可以描述一组服务，最终实现一个大系统的部署。本次更新内容如下： Networking Fix a daemon start panic on armv5 #24315 Vendor libnetwork #26879 #26953 Avoid returning early on agent join failures docker/libnetwork#1473 Fix service published port cleanup issues docker/libetwork#1432 docker/libnetwork#1433 Recover properly from transient gossip failures docker/libnetwork#1446 Disambiguate node names known to gossip cluster to avoid node name collisiondocker/libnetwork#1451 Honor user provided listen address for gossip docker/libnetwork#1460 Allow reachability via published port across services on the same host docker/libnetwork#1398 Change the ingress sandbox name from random id to just ingress_sboxdocker/libnetwork#1449 Swarm Mode Fix remote detection of a node's address when it joins the cluster #26211 Vendor SwarmKit #26765 Bounce session after failed status update docker/swarmkit#1539 Fix possible raft deadlocks docker/swarmkit#1537 Fix panic and endpoint leak when a service is updated with no endpoints docker/swarmkit#1481 Produce an error if the same port is published twice on service create or service updatedocker/swarmkit#1495 Fix an issue where changes to a service were not detected, resulting in the service not being updated docker/swarmkit#1497 Contrib Update the debian sysv-init script to use dockerd instead of docker daemon #25869 Improve stability when running the docker client on MacOS Sierra #26875 Windows Fix an issue where arrow-navigation did not work when running the docker client in ConEmu #25578 发行说明及下载地址： https://github.com/docker/docker/releases/tag/v1.12.2-rc2 https://github.com/docker/docker/blob/master/CHANGELOG.md Docker v1.12.2-RC2 发布，修复 Bug下载地址
