Install Ubuntu¶
Step 103-setup-using-ansible would have setup alpine1 to perform the functions required for the Ubuntu Auto install steps.
We now have some manual tasks to create the user-data-mac-address file for each of the Virtual Machines created ( excluding alpine1)
Step 1¶
Start and stop all the Virtual Machines created.¶
For the following step, the Virtual Machines created must be started once to generate the mac-address.
From PowerShell ISE open G:\kubernetes-lab\srv\scripts\get-hyperv-startVM.ps1
Click on the Green Play button, this will execute the script.
This will start and then stop all the Virtual Machines . Ensure the Virtual Machine names are not changed.
You can also Start and Stop from the Hyper-V Console.
Step 2¶
Generate user-data-mac-address file.¶
For a Kubernetes cluster we will need multiple Virtual Machines. This will require multiple user-data-mac-address files to be created. Here I use PowerShell to generate the files.
From PowerShell ISE open G:\kubernetes-lab\srv\scripts\get-hyperv-VM-mac.ps1
Click on the Green Play button, this will execute the script.
The generated files are in the subfolder .\autoinstall\
From the configuration in step 112 , the Boot sequence is looking up the location. http://192.168.100.1/autoinstall/
This is from the following code
Copy the files created to the folder
/srv/autoinstall/ on the alpine1 server. The duplicate file with the node name is workaround to show the hostname of the specific file. As I did not find away to identify the hostname using the Ubuntu autoinstall method.
If you recall from 104-setup-nginx, the folder /srv/ was exposed to be visible from http://192.168.100.1/. All folders created in /srv/ will be listed via the browser.
Copy the files using WSFTP or some other method .
Validate by browsing http://192.168.100.1/

The MAC addresses for a newly created Hyper-V VM is not generated until its started at least once.
