Ironic POC basic test environment

OpenStack host interfaces:

  • eno1 - for SSH and external VIP (IP: 172.28.128.1/16)
  • enp131s0f0 - bridged through br-ironic to the network where baremetal hosts are (IP: 192.168.10.1/24)
  • enp131s0f1 - dedicated interface for IPMI (IP: 192.168.201.254/24)


Revision of kolla-ansible used (branch stable/rocky): 

commit 668da3c332fcd58fa2b023e8bb74ca8225e222bc

    Add cache configuration for ceilometer project

    when using ceilometer+gnocchi, for every notification sample, ceilometer
    will update the resource even if is not updated.

    We should add [cache] section to make ceilometer cache the resource, and
    stop send the useless update request.

    Closes-Bug: #1807841
    Change-Id: Ic33b4cd5ba8165c20878cab068f38a3948c9d31d
    (cherry picked from commit 55bf29ec6c459dc46cefdee69acb8e427763e409)

Standard all-in-one inventory has been used.

Config overrides for Ironic (/etc/kolla/config/ironic/ironic-conductor.conf): 

[DEFAULT]
my_ip=192.168.10.10
enabled_network_interfaces=noop,flat,neutron
default_network_interface=flat

[deploy]
default_boot_option = netboot

Here, eno1 is the interface providing access to the Ironic host from inside the Labs: 

[root@alanis ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno1
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="none"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="eno1"
UUID="7e04ebd9-2e2a-4297-b417-b9cb5e498259"
DEVICE="eno1"
ONBOOT="yes"
IPADDR="172.28.128.1"
PREFIX="16"
GATEWAY="172.28.0.2"
DNS1="172.28.0.2"
DNS2="8.8.8.8"
IPV6_PRIVACY="no"

enp131s0f0 is an interface that is up, but has no IP set (this will be used by Neutron to put external bridge on) and enp131s0f1.10 is a tagged secondary interface used for hosting internal OpenStack APIs and Ironic's TFTP server. 

[root@alanis ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp131s0f1.10
DEVICE=enp131s0f1.10
NAME=enp131s0f1.10
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.10.10
PREFIX=24
NETWORK=192.168.10.0
VLAN=yes

Note that because OpenStack here is deployed on a single machine, HAProxy is not strictly required.

If your playbook creates the ironic_dnsmasq container, stop/remove it, so you don't run into potential problems with 2 DHCPs on the same network.

Post deployment setup

Follow https://docs.openstack.org/kolla-ansible/rocky/reference/ironic-guide.html#post-deployment-configuration

For building baremetal images follow https://docs.openstack.org/ironic/rocky/install/configure-glance-images.html Here is an example of an Ubuntu image with a heat agent allowing to run script-based software deployments: 

$ disk-image-create baremetal ubuntu dhcp-all-interfaces os-collect-config os-refresh-config os-apply-config heat-config heat-config-cfn-init heat-config-script -o ubuntu-software-config-ironic.qcow2

Add images to Glance: 

$ openstack image create --container-format aki --disk-format aki --file ~/ubuntu-software-config-ironic.vmlinuz ubuntu-software-config-ironic_kernel
$ openstack image create --container-format ari --disk-format ari --file ~/ubuntu-software-config-ironic.initrd ubuntu-software-config-ironic_initramfs
$ openstack image create --public --container-format bare --disk-format qcow2 --file ~/ubuntu-software-config-dgx.qcow2 --property kernel_id=a8743614-38dc-43ed-8d3b-f4e1b4240eb0 --property ramdisk_id=1d370924-762b-49a0-8619-7f13aa8dafe1 ubuntu-software-config-dgx

In the last command kernel_id and ramdisk_id point to UUIDs of kernel and ramdisk images assigned them by Glance.

Note on localboot: The above setup is susceptible to this bug: https://storyboard.openstack.org/#!/story/2002929. To avoid the problem you can set default_boot_option = local in Ironic overrides, so that your baremetal servers will be able to boot from their local disk after they are done provisioning. More importantly, with local boot you can use regular cloud images - without having to extract kernel and ramdisk out of them first (you'll still need the kernel and ramdisk for initial deploy). This approach will be used in the next section.

Network interface config is exactly the same as in the previous iteration of the deployment (without multi-tenancy).
