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
