The Deis project is proud to announce v1.4.0, with community-driven support for provisioning on Microsoft Azure, improvements to AWS provisioning, and a scalable Ceph store-gateway.

If you are coming from an earlier version of Deis, please read the "Upgrading Deis" documentation for details.

What is Deis?

Deis is an open source PaaS that makes it easy to deploy and manage applications on your own servers. Deis builds upon Docker and CoreOS to provide a lightweight PaaS with a Heroku-inspired workflow.

What's Next

Application SSL Support

Thanks to community discussion and effort, work on application SSL support has begun. What remains is an agreement on the formal specification following Heroku and an updated implementation. Once merged, users will be able to install custom private keys and SSL certificates to expose HTTPS applications using the Deis router.

Improved Test Infrastructure

We need to speed up test suites, eliminate the PR build queue, and increase test coverage to include operational aspects such as upgrades and HA. Hard work behind the scenes and invaluable community support are steadily improving the Deis test infrastructure.

New Container Scheduler

Application containers require a resource-aware scheduler to improve cluster efficiency at scale and to alleviate issues with cluster balancing after the loss of a node. Prototyping is well underway with Swarm and Kubernetes.

Deis will continue to support fleet for both control plane and data plane scheduling for the foreseeable future.
