Deis is an open source PaaS that makes it easy to deploy, scale and manage Docker containers used to host applications and services. Deis builds upon Docker and CoreOS to provide a private PaaS that is lightweight and flexible.
Deis is a set of Docker containers that can be deployed anywhere including public cloud, private cloud, bare metal or your workstation. You will need Docker and a CoreOS cluster to get started.
Build Deis and run the deis/deis Docker image.
make build
make run
Use pip to install the latest Deis Client, or download pre-compiled binares.
pip install deis
Use the Deis Client to register a new user.
deis register http://localhost:8000
Initalize a dev cluster with a list of CoreOS hosts and your CoreOS private key.
deis clusters:create dev deisapp.com --hosts=coreos-host1,coreos-host2,coreos-host3 --auth=~/.ssh/coreos
The dev cluster will be used as the default cluster for future deis commands.
Create an application on the default dev cluster.
deis create
Use deis create --cluster=prod to place the app on a different cluster. Don't like our name-generator? Use deis create myappname.
Push builds of your application from your local git repository or from a Docker Registry. Each build creates a new release, which can be rolled back.
When you created the application, a git remote for Deis was added automatically.
git push deis master
This will use the Deis builder to package your application as a Docker Image and deploy it on your application's cluster.
You can also push builds directly from the Docker Index or a private Docker registry. First, build and push the Docker images as you normally do:
docker build -t gabrtv/example
docker push gabrtv/example
Then use deis push to deploy.
deis push gabrtv/example
Use the fully qualfied image path to push from a private registry: deis push registry.local:5000/gabrtv/example
Configure your application with environment variables. Each config change also creates a new release.
deis config:set DATABASE_URL=postgres://
Coming soon: Use the integrated ETCD namespace for service discovery between applications on the same cluster.
Test your application by running commands inside an ephemeral Docker container.
deis run make test
To integrate with your CI system, check the return code.
Scale containers horizontally with ease.
deis scale 8
To scale by process type, use deis scale web=8 worker=2 . Just make sure the process types can be run via /start web.
Publish your application via each cluster's integrated router.
deis publish 8080/http
deis domain myapp.example.com
Use deis open to pop into a browser pointed at your application. Use --sslCert=cert.pem --sslKey=key.pem to secure the connection with SSL/TLS.
Access to aggregated logs makes it easy to troubleshoot problems with your application.
deis logs
Use deis run to execute one-off commands and explore the deployed container. Coming soon: deis attach to jump into a live container.
