4mitch / Install_Alpine_Linux_3.3_on_VirtualBox_OSX.md

Created July 12, 2018 08:46 — forked from kennwhite/Install_Alpine_Linux_3.3_on_VirtualBox_OSX.md

Howto: Install Alpine Linux 3.3 on VirtualBox OSX

Latest Standard ISO version x86_64 is recommended (http://alpinelinux.org/downloads/)
Create new VM ("Linux 2.6 / 3.x / 4.x (64-bit)")
1 CPU w/ 512BM RAM and 1 GB default (VDI) disk is more than sufficient
Default networking (NAT)
Boot and add Alpine ISO as attached virtual install media
Default root password is blank (though note - ssh PermitRootLogin defaults to disallow blank passwords and: prohibit-password; switch to yes for Host ssh)
Run setup-alpine
Defaults are fine, but you do want "sys" disk setup to sda, y to confirm
