Deploy a Docker Swarm cluster with InfraKit
Bootstrap
First, the cluster should be bootstrapped to get InfraKit running and ready to deploy the Swarm cluster.
Available bootstraps:
AWS
The Cloudformation template bootstrap.yml creates a VPC, subnet, internet gateway and the minimum required to build EC2 instances.
Select the instance type and the name of the EC2 Key pair name.
One EC2 instance will be created and will run InfraKit, it's public IP is revealed in the Cloudformation outputs.
DigitalOcean
Coming soon
Docker in Docker
bootstrap.sh -p docker
Deploy
The InfraKit instance renders the config.tpl template, and watches the resulting file (config.json).
The result is the full Swarm cluster.
Security
The Swarm cluster is by default secured with self managed certificates. The manager node remote API is enabled to allow nodes to get the join token, certificates are signed by a CA hosted on the bootstrap instance to enable mutual authentication. The certificate management is only for demonstration purpose, not for production.
