In this post, I will talk about supported operating systems for deploying TKG Management and Workload Clusters. This is not applicable if you are working on vSphere with Tanzu.
In the following table, you can see the different OS supported under different infra/cloud providers.
| Image Type | vSphere | AWS | Azure |
|---|---|---|---|
| Distributed with TKG | Ubuntu 20.04 Photon OS 3 | Ubuntu 20.04 Amazon Linux 2 | Ubuntu 20.04 Ubuntu 18.04 |
| Custom Image | Ubuntu 20.04 Ubuntu 18.04 RHEL 7 Photon OS 3 | Ubuntu 20.04 Ubuntu 18.04 Amazon Linux 2 | Ubuntu 20.04 Ubuntu 18.04 |
Distributed with TKG
Distributed with TKG is what VMware provide us and you might have been using those images. In my case, I am using Ubuntu with vSphere most of the time. There is no specific reason and you can use Photon too.
Custom Image
This is where we are interested in this article. So, Custom images are the one which we can create for deploying TKG clusters but Custom image should be based on one of the supported OS listed in table above.
In my upcoming blogs, i will talk about how to create a custom image.
