Ironic OverCloud Test

Instructions

• Install the undercloud as usual: https://www.rdoproject.org/tripleo/.
  • You can try it on both virtual and real bare metal environment.
    • For virt (running on virthost) make sure you can ssh root@127.0.0.2 without password then:
    • git clone https://github.com/openstack/tripleo-quickstart
    • bash tripleo-quickstart/quickstart.sh –no-clone –clean –config tripleo-quickstart/config/general_config/minimal.yml –teardown all –release stable/newton 127.0.0.2
    • This will stop after installing the undercloud, and we can continue with later steps on the undercloud with:
      • ssh -F ~/.quickstart/ssh.config.ansible undercloud
    • We need to upload images to glance before continuing though:
      • source stackrc; openstack overcloud image upload
  • Do not enroll all nodes you have in the undercloud, leave something for overcloud Ironic!
    • In order to split the nodes up we need a slightly modified version of instructions so we get just one node in each group:
      • jq '.nodes[0:1] | {nodes: .}' instackenv.json > undercloud.json
      • jq '.nodes[1:2] | {nodes: map({driver: .pm_type, name: .name, driver_info: {ssh_username: .pm_user, ssh_address: .pm_addr, ssh_key_contents: .pm_password, ssh_virt_type: "virsh"}, properties: {cpus: .cpu, cpu_arch: .arch, local_gb: .disk, memory_mb: .memory}, ports: .mac | map({address: .})})}' instackenv.json > overcloud-nodes.yaml
    • Then we only register the undercloud.json on the undercloud:
      • source stackrc; openstack baremetal import undercloud.json
• Then follow http://tripleo.org/advanced_deployment/baremetal_overcloud.html
  • It has an example deployment test procedure in the end
  • Sample ironic-config.yaml provided below, but note that they don't allow virtual compute nodes!
    • looks like a tripleoclient bug, but even with below configs we need to pass '–compute-scale 0' if we only have one node registered
• Join #openstack-ironic on Freenode, if you have problems with Ironic specifically (feel free to ping dtantsur there)
• Document known issues and workarounds in https://etherpad.openstack.org/p/rdo-newton-ga-testday-workarounds

Simplest ironic-config.yaml (bare metal)

parameter_defaults:
	IronicEnabledDrivers:
		- pxe_ipmitool
		- pxe_drac
		- pxe_ilo
	IronicCleaningDiskErase: 'metadata'
	ControllerCount: 1
	ComputeCount: 0

Note: feel free to remove IronicCleaningDiskErase if your machine supports ATA secure erase, or if you're fine with waiting for the disks to get shredded (the latter may take hours).
