How to passthrough SATA drives directly on VMWare EXSI 6.5 as RDMs

There aren't many tutorials about this, the only tutorials I've found were about passing through entire PCIe cards to VMs, or refered to old ESXI versions (below 6.5) that used a more comprehensive desktop client instead of the web app. In v6.5, the web app was introduced and the desktop client was deprecated.

This tutorial shows you how to pass SATA HDDs to the virtual machine on VMWare ESXI 6.5. This tutorial is partially based on VMWare's own KB and the now deprecated Forza IT blog post.

    // Start with a temperature, in Kelvin, somewhere between 1000 and 40000.  (Other values may work,
    //  but I can't make any promises about the quality of the algorithm's estimates above 40000 K.)

Building Docker image with Packer and provisioning with Ansible

Overview

Packer

• Packer is used to build image from a base image, perform provisions and store (commit) the final image.

• We use provisioners and Packer templates to do the actual work to create the final image.

• We use Ansible for provisioning.
