Docker Releases Runtime Compliant with Open Container Initiative

Docker announced its first release built on runC and containerd.

Docker said its Engine 1.11 demonstrates real progress with the Open Container Initiative (OCI), which was launched last year with a mission to build a vendor-neutral, portable and open specification and runtime for container-based solutions. Docker donated its container format and runtime to the OCI under the Linux Foundation in June of last year.

In December 2015, Docker introduced containerd, a daemon to control runC., which is the first compliant implementation of the Open Containers Runtime specification and the default executor bundled with Docker Engine.

Some highlights of Docker Engine 1.11:

• DNS round robin load balancing between containers with Docker’s networking. 
• VLAN support (experimental)
• IPv6 service discovery: Engine’s DNS-based service discovery system can now return AAAA records.
• Yubikey hardware image signing
• Labels on networks and volumes
• Better handling of low disk space with device mapper storage

Open Container Initiative Gains Early Traction

The Open Container Initiative (previously known as the Open Container Project) published its draft charter for comment and announced that 11 new companies are joining this industry-wide initiative to develop common standards for software containers. The OCI, which was announced just last month at DockerCon and is being hosted at The Linux Foundation as a Collaborative Project.

Companies signaling their formal commitment to this effort include AT&T, ClusterHQ, Datera, Kismatic, Kyup, Midokura, Nutanix, Oracle, Polyverse, Resin.io, Sysdig, SUSE, Twitter and Verizon. Amazon Web Services, Apcera, Cisco, CoreOS, Docker, EMC, Fujitsu Limited, Goldman Sachs, Google, HP, Huawei, IBM, Intel, Joyent, Mesosphere, Microsoft, Pivotal, Rancher Labs, Red Hat and VMware are also committed to the Open Container Initiative.

As part of the formation, Docker Inc. donated its base container format at runtime to serve as cornerstone technologies under the governance of the OCI, while leadership from Application Container spec (“appc”) is also represented.

The OCI said work is underway on the draft specification, which is expected to be available for community comment within the month.

“The overwhelming interest in the Open Container Initiative is representative of both the opportunity containers offer for application development and the challenges we face with fragmentation,” said Jim Zemlin, executive director at The Linux Foundation. “With such strong community support and collaboration, we’re confident this effort will rise to the opportunity.”
