Combining parts

You can combine the parts in different ways using the yay language.

Create and provision a cloud server

You can use a Compute part to provide the server key of the Provisioner part:

new Provisioner as vm1:
    new Compute as server:
        name: mytestvm1
        driver:
            id: VMWARE
        image:
            id: /home/john/vmware/ubuntu/ubuntu.vmx
        user: ubuntu

    resources:
      - Package:
          name: git-core

When the Provisioner part tries to access server.fqdn the Compute part will automatically find an existing mytestvm1 or create a new one if needed.

Create a new instance and automatically set up DNS

You can use the IP from a Compute part in other parts just by using it like any other variable:

new Compute as server:
    name: mytestserver
    driver:
        id: EC2
        key: secretkey
        secret: secretsecret
    image: imageid
    size: t1.micro

new Zone as dns:
    driver:
        id: ROUTE53
        key: secretkey
        secret: secret
    domain: mydomain.com
    records:
      - name: www
        type: A
        data: {{ server.public_ip }}

Create and provision interdependent cloud servers

You can refer to server A from the configuration for server B and vice versa and Yaybu will satisfy the dependcies automatically:

new Provisioner as vm1:
    new Compute as server:
        name: mytestvm1
        driver:
            id: VMWARE
        image:
            id: /home/john/vmware/ubuntu/ubuntu.vmx
        user: ubuntu

    resources:
      - File:
          name: /etc/foo
          template: sometemplate.j2
          template_args:
              vm2_ip: {{ vm2.server.public_ips[0] }}

new Provisioner as vm2:
    new Compute as server:
        name: mytestvm2
        driver:
            id: VMWARE
        image:
            id: /home/john/vmware/ubuntu/ubuntu.vmx
        user: ubuntu

    resources:
      - File:
          name: /etc/foo
          template: sometemplate.j2
          template_args:
              vm1_ip: {{ vm1.server.public_ips[0] }}

here a templated File on mytestvm1 needs the IP address of mytestvm2. mytestvm2 needs the IP address of mytestvm1. Yaybu is able to work out that it should activate both Compute parts first, then proceed to provision both template files to the instances.
