This builds an up-to-date Vagrant Alpine Linux Base Box.
Currently this targets Alpine Linux 3.14.
Usage
Install Packer (1.7+), Vagrant (2.2.16+) and VirtualBox (6.1+).
If you are on a Debian/Ubuntu host, you should also install and configure the NFS server. E.g.:
# install the nfs server.
sudo apt-get install -y nfs-kernel-server
# enable password-less configuration of the nfs server exports.
sudo bash -c 'cat >/etc/sudoers.d/vagrant-synced-folders' <<'EOF'
Cmnd_Alias VAGRANT_EXPORTS_CHOWN = /bin/chown 0\:0 /tmp/*
Cmnd_Alias VAGRANT_EXPORTS_MV = /bin/mv -f /tmp/* /etc/exports
Cmnd_Alias VAGRANT_NFSD_CHECK = /etc/init.d/nfs-kernel-server status
Cmnd_Alias VAGRANT_NFSD_START = /etc/init.d/nfs-kernel-server start
Cmnd_Alias VAGRANT_NFSD_APPLY = /usr/sbin/exportfs -ar
%sudo ALL=(root) NOPASSWD: VAGRANT_EXPORTS_CHOWN, VAGRANT_EXPORTS_MV, VAGRANT_NFSD_CHECK, VAGRANT_NFSD_START, VAGRANT_NFSD_APPLY
EOFFor more information see the Vagrant NFS documentation.

cd example
vagrant up --provider=virtualbox
vagrant ssh
exit
vagrant destroy -fPacker boot_command
The following table describes the steps used to install Alpine Linux.
NB This Packer boot_command method of installation is quite brittle, if you are having trouble installing, try increasing the install wait timeout, or changing the Alpine mirror in the answers file to one near you.
| step | boot_command |
|---|---|
| login as root | root<enter> |
| bring up the network | ifconfig eth0 up && udhcpc -i eth0<enter><wait5> |
| download the setup answers | wget -q http://{{.HTTPIP}}:{{.HTTPPort}}/answers<enter><wait> |
| run the setup | setup-alpine -f $PWD/answers<enter><wait5> |
| type the root password | vagrant<enter> |
| re-type the root password | vagrant<enter> |
| wait for the services to start | <wait30s> |
| confirm that we want to erase sda | y<enter> |
| wait for the installation to finish | <wait4m> |
| mount the root partition | mount /dev/sda3 /mnt<enter> |
| configure sshd to allow root login | sed -i -E 's,#?(PermitRootLogin\s+).+,\1yes,' /mnt/etc/ssh/sshd_config<enter> |
| reboot to the installed system | reboot<enter> |
