Docker today announced the general availability of the Docker Trusted Registry, a piece of software that companies can use to securely store their container images.

The Docker Trusted Registry, which first launched in beta in February and was previously known by the name Docker Hub Enterprise, includes management features and commercial support. It comes with Active Directory and LDAP support and audit logging.

Companies can run it in public clouds or in on-premises data centers. IBM has already said it would resell the software, and the Microsoft Azure Marketplace already carries it. Amazon Web Services will offer it, too.

This is the most enterprise-oriented announcement so far during Docker’s DockerCon conference, which has been taking place in San Francisco this week. The rollout comes after Docker’s executives noticed that the open-source registry has been downloaded more than 6.5 million times, Scott Johnston, Docker’s senior vice president of product management, said onstage today. “There’s got to be a commercial product in here somewhere,” Johnston said. The first customer, he said, is the U.S. General Services Administration.

The arrival of Docker Trusted Registry, which costs at least $150 per month, fits in to the monetization strategy of Docker, which is arguably the hottest enterprise software startup around at the moment. Docker’s open-source container technology has become popular among developers for packaging up their code in a way that it can be easily moved from one server environment to another. But by all accounts, revenue growth has been slow.

If things work out the way executives are hoping, Docker could now start to take in serious money as more companies try deploying many applications in containers instead of in more traditional virtual machines.

Things do look promising. Docker said in a statement today that the Trusted Registry beta attracted the attention of more than 800 organizations.
