IBM today announced that it is the first company to resell Docker Trusted Registry, a piece of software for on-premises data centers from hot enterprise startup Docker.

Docker itself announced today the availability of Docker Truster Registry version 1.1 at the DockerCon conference in San Francisco. Now IBM will sell it to customers. Docker Truster Registry integrates with IBM’s UrbanCode and PureApplication System tools, IBM noted in a statement.

IBM today is also announcing the general availability of IBM Containers, a cloud service for deploying applications in containers on the IBM Bluemix platform-as-a-service (PaaS) cloud. IBM launched IBM Containers in beta in December.

The announcements show the potential for widespread adoption of Linux containers — a lightweight alternative to longstanding virtual machine technology for running many applications on a single physical server — among enterprises.

As a cloud provider, IBM is no different from Amazon and Google in wanting to support this application deployment model. But IBM has a long history of selling technology to large companies, so the new commitment is telling.

Today’s statement from IBM gives some insight into enterprise adoption thus far:

Containers have proved to be effective in a number of enterprises in industries such as financial services, hospitality, retail, healthcare, cloud service providers and others.

Docker does have partnerships with other enterprise tech vendors, like Microsoft, Red Hat, and VMware. But at least IBM can claim that it’s first to resell the Docker Trusted Registry.
