Use FreeBSD Host poudriere repositories inside a jail

WARNING: the following are my personal notes. Use at your own risk!

Create jail mountpoint from FreeBSD Host (or inside jail):

mkdir -p /usr/jails/www/var/ports/packages/

Create jail fstab file on FreeBSD Host:

# cat /etc/fstab.www
/usr/local/poudriere/data/packages/13amd64-www-www/ /usr/jails/www/var/ports/packages/ nullfs ro 0 0

Add following option to jail configuration under /etc/jail.conf.d:

# grep  fstab www.conf
  mount.fstab = "/etc/fstab.www";

Use poudriere mounted repository inside jail:

mkdir -p /usr/local/etc/pkg/repos

root@www:/usr/local/etc/pkg/repos # cat www.conf
proxy: {
  url : "file:///var/ports/packages",
  enable : yes,
  signature_type : NONE,
  mirror_type : NONE
}

FreeBSD: {
  enabled: no
}
root@www:/usr/local/etc/pkg/repos #

pkg update
root@www:~ # pkg install `pkg search -g '*' | awk '{print $1}'`
