After sealing a number of acquisitions over the past 18 months, Docker has pounced again, this time bringing the Tutum cloud service for Dockerized apps into the fold.
The Tutum Docker platform, acquired on undisclosed terms, is designed to help devs and ops teams deploy and manage Docker distributed apps in production.
Where Tutum fits into Docker's plans is in helping it complete its goal of offering a full commercial platform for the application lifecycle.
Its existing Docker Hub cloud service covers the building and shipping of container apps, while Tutum deals with their provisioning, deployment and management.
"We have our Docker Hub cloud service for development teams, with guided workflows to get people through building tasks. Whereas what Tutum helps to fill is specifically addressing the deployment and management of distributed applications in production," Docker SVP marketing David Messina said.
"It does it in a way that really unifies collaboration between developers and operations. So developers can deploy the applications and operations can provision the right kind of infrastructure anywhere for Dockerized applications to run."
Docker is the most popular technology for automating the creation and deployment of apps in containers - a lighter-weight form of virtualisation.
The idea is to free developers from software and infrastructure dependencies, cutting costs and creating efficiencies in the process. Docker Inc, the company, is the open-source platform's corporate sponsor.
Tutum CEO and co-founder Borja Burgos-Galindo said his entire team will be relocating to Docker in San Francisco. Branding for the service, which Docker says has 25,000 users, has yet to be determined.
"One of the reasons we decided to join Docker was really that we had both set out to enable developers to build and run any application on any infrastructure - that's what we set out to do two years ago - and that's one of things that Docker is doing," Burgos-Galindo said.
"So that's what we'll be working on. How do we enable developers, how do we enable IT teams really to take any application that they write and get it up and running on any infrastructure simply and flexibly?"
Tutum automates the process of infrastructure provisioning across any cloud provider or on premises. Then using any Docker API-compatible registry, the service helps get the application deployed and up and running on the new infrastructure.
Once the infrastructure is in place and the application running, Tutum enables the user to scale, roll back, update, stop, start and restart applications, with upgrades and updates.
In March, Docker acquired startup SocketPlane, to help add standard networking interfaces to Docker, and Canadian company Kitematic and its eponymous open-source GUI tool for installing Docker. A month later, Docker secured a $95m funding injection.
The previous July it had acquired London-based Orchard Laboratories, makers of the Orchard and Fig applications. In October 2014, software-testing firm Koality became part of Docker.
