When installing Alpine Linux on an ESXi or VSphere system you definitely want to enable the hypervisor tools. The good news is that Alpine has this package ready to go! Open-VM-Tools provides the VMWare hypervisor info from Alpine and other Linux. https://github.com/vmware/open-vm-tools
Since alpine 3.12 the open-vm-tools version 11 was split into packages:
guestinfo is required for IP Discovery to work.
deploypkg provides support for Guest OS Customization
Enable the community repository by editing /etc/apk/repositories and uncommenting the community repository, and then run apk update.
