Deis v1.6 - Docker Swarm Tech Preview
Deis is now supported by Engine Yard!
If you are coming from an earlier version of Deis, please read the "Upgrading Deis" documentation for details.
What is Deis?
- Docker Swarm is available for preview as an alternative to Fleet for scheduling application units
- EC2 provisioning supports the Proxy Protocol, allowing WebSocket support for apps through an Elastic Load Balancer
- SSL certificates in SAN format are now supported
deis users:listallows an admin to see all registered Deis users
deis ps:restartstops and starts all containers, all those of a process type, or a single container
deis config:pushallows a
--pathargument to the
-nto limit the number of lines displayed
- user registration can be
disabled, or set to
- logging level in router can be customized
- the number of worker processes in controller can be scaled
deis registerchecks for a valid controller URL before continuing
- logger exposes its config as feature flags, and is more extensible
- Azure provisioning creates a load-balanced HTTPS endpoint
- EC2 provisioning shows a countdown timer and reports any CloudFormation errors
git pusherrors are handled and reported more reliably
deis keys:adduses SSH fingerprints to determine uniqueness
- registry determines S3 bucket name dynamically from
- moved route53-wildcard.py script to contrib/ec2 to help with DNS setup
make -C controller/ postgrescreates a DB container for running unit tests
Under the Hood
- bumped CoreOS to 633.1.0
- updated Ceph to "Hammer" release
confdto v0.9.0 in all components
- builder now uses the official
- router updated to nginx 1.9 for stream module TCP support
- added new C4 instance types to EC2 provisioning
- added sfo1 and ams2 data centers to DigitalOcean provisioning
For more details, please see CHANGELOG.md.
New Container Schedulers
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. In addition to the Swarm technology preview in this release, prototyping is underway with Kubernetes and Mesos.
Deis will default to using fleet for both control plane and data plane scheduling for the foreseeable future.
Improved Test Infrastructure
We need to speed up test suites 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.
We want to thank the following Deis community members for creating GitHub issues, providing support to others, and working on various Deis branches:
