Currently, within our Icehouse Openstack environment, we are trying to see if we can 1) setup a cluster of CoreOS VMs by using the Heat template 2) invoking the fleetctl command to deploy the Docker containers to the newly setup CoreOS cluster by placing some instructions in the Heat template.
Achieving the goal 1) is not tough and we can see some samples over the net too. For example, we can use the following template to setup a CoreOS-based VM successfully. heat_template_version: 2013-05-23 description: > A simple Heat template to deploy CoreOS into an existing cluster. parameters: network_id: type: string label: Network ID description: ID of existing Neutron network to use default: 632e1048-0164-41bd-9332-01c664eb475f image_id: type: string label: Glance Image ID description: ID of existing Glance image to use default: dfdd6317-5156-4e7d-96a1-f7ce76a43687 resources: instance0_port0: type: OS::Neutron::Port properties: admin_state_up: true network_id: { get_param: network_id } security_groups: - 435c19ea-64d0-47f9-97e6-bc04b98361eb instance0: type: OS::Nova::Server properties: name: coreos-test image: { get_param: image_id } flavor: m1.small networks: - port: { get_resource: instance0_port0 } key_name: mykey user_data_format: RAW user_data: | #cloud-config coreos: etcd: discovery: https://discovery.etcd.io/249d48e8dff562bdd8381177020ee405 addr: $private_ipv4:4001 peer-addr: $private_ipv4:7001 units: - name: etcd.service command: start - name: fleet.service command: start Initially, we tried to achieve goal 2) by testing if we can send mime multi part user_data (the second part of the user_data will be a shell script that uses fleetctl command to deploy containers; if there is any synchronization / wait condition needs to be done, we can handle it there somehow too) to CoreOS cloud-init service. However, it seems like that CoreOS (at least Stable 410.1.0) cloud-init does not support mime multi part yet. Any other good way to achieve both goals 1) & 2)?
