Provision a Deis Cluster on Amazon EC2

Install the AWS Command Line Interface:

$ pip install awscli
Downloading/unpacking awscli
  Downloading awscli-1.3.6.tar.gz (173kB): 173kB downloaded
  ...

Configure aws-cli

Run aws configure to set your AWS credentials:

$ aws configure
AWS Access Key ID [None]: ***************
AWS Secret Access Key [None]: ************************
Default region name [None]: us-west-1
Default output format [None]:

Upload keys

Generate and upload a new keypair to AWS, ensuring that the name of the keypair is set to "deis".

$ ssh-keygen -q -t rsa -f ~/.ssh/deis -N '' -C deis
$ aws ec2 import-key-pair --key-name deis --public-key-material file://~/.ssh/deis.pub

Choose number of instances

By default, the script will provision 3 servers. You can override this by setting DEIS_NUM_INSTANCES:

$ export DEIS_NUM_INSTANCES=5

Note that for scheduling to work properly, clusters must consist of at least 3 nodes and always have an odd number of members. For more information, see optimal etcd cluster size.

Deis clusters of less than 3 nodes are unsupported.

Choose number of routers

By default, the Makefile will provision 1 router. You can override this by setting DEIS_NUM_ROUTERS:

$ export DEIS_NUM_ROUTERS=2

Customize user-data

Edit user-data and add a new discovery URL. You can get a new one by sending a request to http://discovery.etcd.io/new.

Customize cloudformation.json

By default, this script spins up m3.large instances. You can override this by adding a new entry to cloudformation.json like so:

    {
        "ParameterKey":     "InstanceType",
        "ParameterValue":   "m3.xlarge"
    }

The only entry in cloudformation.json required to launch your cluster is KeyPair, which is already filled out. The defaults will be applied for the other settings.

Run the provision script

Run the cloudformation provision script to spawn a new CoreOS cluster:

$ cd contrib/ec2
$ ./provision-ec2-cluster.sh
{
    "StackId": "arn:aws:cloudformation:us-west-1:413516094235:stack/deis/9699ec20-c257-11e3-99eb-50fa01cd4496"
}
Your Deis cluster has successfully deployed.
Please wait for all instances to come up as "running" before continuing.

Initialize the cluster

Once the cluster is up, get the hostname of any of the machines from EC2, set FLEETCTL_TUNNEL, and issue a make run from the project root:

$ ssh-add ~/.ssh/deis
$ export FLEETCTL_TUNNEL=ec2-12-345-678-90.us-west-1.compute.amazonaws.com
$ cd ../.. && make run

The script will deploy Deis and make sure the services start properly.

Configure DNS

While you can reference the controller and hosted applications with public hostnames provided by EC2, it is recommended for ease-of-use that you configure your own DNS records using a domain you own. See Configuring DNS for details.

Use Deis!

After that, register with Deis!

$ deis register http://deis.example.org
username: deis
password:
password (confirm):
email: [email protected]

Hack on Deis

If you'd like to use this deployment to build Deis, you'll need to set DEIS_HOSTS to an array of your cluster hosts:

$ export DEIS_HOSTS=1.2.3.4 1.2.3.5 1.2.3.6

This variable is used in the make build command.
