Stage PNDA mirror & components

Introduction

In order to make built components available during the PNDA provisioning process, they need to be staged in a location that is accessible from the target environment via HTTP.

Creating PNDA Mirror VM

This VM will be the HTTP server from which PNDA will install the software it needs during the installation process. The software is built from our GitHub and simply copied to the relevant location.

Walkthrough

Creating the VM

sudo qemu-img create -f qcow2 -o preallocation=metadata /var/lib/libvirt/images/appserver.qcow2 40G
sudo virt-install  --name=appserver --file=/var/lib/libvirt/images/appserver.qcow2 --graphics vnc,listen=0.0.0.0 --vcpus=1 --ram=4096 --network network=provisioning,model=virtio --os-type=linux --boot hd --dry-run --print-xml > appserver.xml
sudo virsh define appserver.xml
sudo virsh domiflist appserver

Retrieve its mac address

Interface  Type       Source     Model       MAC
-------------------------------------------------------
-          network    provisioning virtio      52:54:00:67:99:43

Create a json file to describe the app server machine (put the mac address above into it)

# cat ~/pnda-apps.json 
{
  "nodes": [

Add the machine to ironic

openstack baremetal import ~/pnda-apps.json
openstack baremetal configure boot

Check the machine existence

[root@undercloud ~]# openstack baremetal list |grep pndaapps
| 0e389292-e8f5-4653-ba04-658b5503ae86 | pndaapps      | None          | power on    | manageable         | True        |

Introspect the machine

ironic node-set-provision-state 0e389292-e8f5-4653-ba04-658b5503ae86 manage
ironic node-set-maintenance 0e389292-e8f5-4653-ba04-658b5503ae86 on
openstack baremetal introspection start 0e389292-e8f5-4653-ba04-658b5503ae86

Wait for introspection to finish

[root@undercloud ~]# openstack baremetal introspection status 0e389292-e8f5-4653-ba04-658b5503ae86
+----------+-------+
| Field    | Value |
+----------+-------+
| error    | None  |
| finished | True  |
+----------+-------+

Set the machine to a deployable state

ironic node-set-provision-state 0e389292-e8f5-4653-ba04-658b5503ae86 provide
ironic node-set-maintenance 0e389292-e8f5-4653-ba04-658b5503ae86 off

Create a flavor and tag everyone as appserver

openstack flavor create --id auto --ram 2048 --disk 10 --vcpus 1 appserver
openstack flavor set --property "cpu_arch"="x86_64" --property "capabilities:boot_option"="local" --property "capabilities:profile"="appserver" appserver
ironic node-update 0e389292-e8f5-4653-ba04-658b5503ae86 add properties/capabilities=profile:appserver,boot_option:local

Create an app server instance

openstack server create --flavor appserver --image pnda-image --key-name default appserver
openstack server list | grep appserver
| 02ac07fa-4816-4636-85b1-e8123412fd19 | appserver | BUILD  | ctlplane=192.0.3.6 |

Once the status is ACTIVE connect to the created server

ssh [email protected]

Install an http server

sudo apt -y install apache2

Stage files

Copy the contents of mirror-dist and pnda-dist from the mirror creation and build steps respectively to the HTTP server.

The final directory layout should resemble the following -

pnda-root
│
├── console-backend-data-logger-develop.tar.gz
├── console-backend-data-logger-develop.tar.gz.sha512.txt
├── etc
│
├── mirror_anaconda
│   ├── Anaconda-4.0.0-el7.parcel
│   ├── etc
│
├── mirror_rpm
│   ├── a-rpm.rpm
│   ├── etc
│
├── etc

Note that pnda-root can be any location, all that is required is that the hierarchy under this is available via a known URI. For example, using a standard Apache 2 installation on RHEL, if the hierarchy above is placed in /var/www/html this will be available via the URI http://<server>/ since /var/www/html is the default document root. Please refer to your HTTP server documentation for more details.

Make a note of the URI to pnda-root as this will be used in configuring the PNDA creation process.
