Ekara core

The Ekara core stack contains the essential components to allows the Ekara platform to work.

The following components are installed:

  • Hashicorp Consul which provides distributed servicesfor the platform: persistence, service discovery, coordination, …
  • The Ekara API which allows to manage an environment from outside.
  • Other Ekara services like auto-deploy.

When using the standard Ekara parent, this stack is always deployed on all manager nodes.

Example

The following Ekara descriptor provisions 3 small EC2 instances in the “eu-west-1” region:

name: myEnvironment

ekara:
  parent:
    repository: ekara-platform/parent
    ref: 1.0.0

nodes:
  app:
    instances: 3
    provider:
      name: ek-aws
      params:
        instances:
          instance_type: "t2.micro"

After creating a minimal infrastructure on AWS for details) and deploying a Docker Swarm cluster on it,a deploy command with the descriptor above will deploy the core stack on all manager nodes.
