Production Baremetal

This is our "Default" configuration for associate sites. It supports federated user login, baremetal provisioning, and isolated, multi-tenant networking to the nodes.

This configuration is baremetal only, and does not support virtualized instances!

Site-Requirements Checklist

Before you begin, ensure you have the following, and note which will be used in your defaults.yml Refer to the host networking configuration for details.

Host Networking Configuration

• A name for your site

  • Friendly name, such as CHI@SITE: openstack_region_name

  • A short name, such as site : chameleon_site_name

• one or more Control Nodes

  • The control node has a linux bridge named public: kolla_external_vip_interface

    • bridged to a physical interface

    • bridged to one half of a veth-pair

    • With an IP address assigned from a publicly routable subnet

    • in this subnet, a reserved (not bound) Public IP for HAProxy VIP: kolla_external_vip_address

      • Public DNS name for this address: kolla_external_fqdn

      • TLS Certificate for this address and name

    • in this subnet, reserved (not bound), one public IP per baremetal node and/or isolated network, minimum 1, 20+ recommended

  • The control node has a linux bridge named internal: network_interface

    • bridged to a physical interface with a vlan trunk to the dataplane switch

    • bridged to one half of a veth-pair

    • With an IP address assigned from a private subnet, referred to as the internal_subnet

    • with a spare (not bound) ip address in internal_subnet for the HAProxy VIP: kolla_internal_vip_address

• at least one Baremetal Node

  • the out of band interface must be accessible by the controller node

• a managed switch with vlan capability

  • Reserved VLANs: 2 minimum, 10+ recommended

    • Ironic Provisioning

    • Shared neutron network

    • 1 per isolated tenant network

  • the PXE capable interface on the Baremetal compute nodes must be connected to this switch

  • the controller node must have a tagged interface, and be a member of the above VLANs

Refer to the above, and we can now follow the QuickStart!
