Docker, CoreOS, Google, Microsoft and Amazon are now working on a new standard for software containers with the help of the Linux Foundation. Other members of this coalition include Apcera, Cisco, EMC, Fujitsu Limited, Goldman Sachs, HP, Huawei, IBM, Intel, Joyent, Mesosphere, Pivotal, Rancher Labs, Red Hat and VMware — that is, virtually everybody who has a stake in building a thriving container ecosystem.
Docker may have become synonymous with containers, but it’s not the only container format around and not everybody agrees that it should become the standard format. Last December, CoreOS announced that it was launching its own container runtime (rkt) and format (appc), a project that received some support from major players like Google, Red Hat and VMware.
At the time, Docker and CoreOS looked like they were on a collision course, and having even more container formats wasn’t likely going to help the overall ecosystem.
