Tripleo-Overcloud – Ranjeet Badhe

In my previous article http://ranjeetbadhe.com/tripleo-undercloud I discussed the Undercloud testbed setup and the installation steps. I hope you have to work Undercloud and we can start the overcloud deployment.

In my testbed, I have got 1 Director node,1 Compute node and 1 Controller node. These nodes are virtualized on ESXi Hypervisor. The below screenshots shows the configuration of these 2 VM’s. For the 3 nodes, I have allocated 24GB memory to each node and 100 GB of Hard Disk space. My first Installation was failing due to less memory allocation, as a result, the system was not able to fork the process, throwing an OS-Refresh error.

Compute Node:

4_Compute node

Controller Node:

3_Control node

Now that our nodes are ready we start by downloading and importing the Overcloud images.

Let us first check our Openstack Service list

Now Start downloading the images

Make a “Images” folder and and Untzar the images into it.

Now upload the Images.

Use this online tool to validate your json file, https://jsonlint.com/

5_MAC

(undercloud) [stack@undercloud ~]$ vi overcloud-stackenv.json
{
“nodes”: [
{
“mac”:[
“00:50:56:8a:c1:90”
],
“cpu“:”4”,
“memory”:”24576″,
“disk”:”100″,
“arch”:”x86_64″,
“name”:”control01″,
“pm_type”:”fake_pxe”

{
“mac”:[

“disk”:”100″,
“arch”:”x86_64″,
“name”:”compute01″,
“pm_type”:”fake_pxe”
}
]
}

Here are few points to note if your test bed is ESXi

By default the fake_pxe driver isn’t enabled on the undercloud. You have to enable it in the /etc/ironic/ironic.conf by modifying the following line:

enabled_drivers = pxe_ipmitool,pxe_ssh,pxe_drac,pxe_ilo,fake_pxe

Now you need to restart the ironic service

sudo systemctl list-unit-files | grep ironic

Validate whether Driver is active

(undercloud) [stack@undercloud images]$ cd ~
(undercloud) [stack@undercloud ~]$ source stackrc
(undercloud) [stack@undercloud ~]$ openstack overcloud node import –introspect –provide overcloud-stackenv.json
