We can install a guest operating system in a VM and control guest operating system customisation for VMs by either running commands directly or, if deploying to vSphere-based cloud platforms, through customisation specifications.

In Aria Automation these commands are defined in a so-called cloudConfig resource property in the cloud template code which holds the commands that should be run. For customisation specifications on the other hand, a property in the cloud template code references a vSphere customisation specification by name.

In this post I’m going to show how to leverage Aria Automation cloudConfig to customise Ubuntu 22 and Windows Server 2022 VMs. Such customisation could include:

• Set the hostname
• Set the timezone
• Configure the network adapter
• Partition, format, mount hard disks
• Run arbitrary commands (e.g. join a domain)

There are two options to customize Aria Automation start page:

• Common title, and landing page title and content
• Image

To change the title and content text, we login the Aria Auto VA using the root account.

Then we navigate into the folder /opt/tarballs/landing-ui/assets/i18n, where a couple of language files are stored in JSON format, e.g. en.json.

Simply adjust the content of these files as required and save each file.

To change the image on the landing page, we again login the Aria Auto VA using the root account.

Then we navigate into the folder /opt/tarballs/landing-ui/assets/img, where the landing page image is stored in SVG format. You can upload your own SVG file here, it must be called welcome-intro-01.svg and saved with file system permissions of 664.

Both actions must be performed on all nodes in a cluster. No restart of any service is required.
