こんな感じでiocage使ってる。exec_poststartはなぜかiocageでjail起動してもrc.dが動いてくれないからworkaround

iocage_setup.sh

#!/bin/sh

JNAME=
IP4ADDR=
IP6ADDR=

iocage create -n $JNAME -r 12.0-RELEASE \
ip4_addr="vtnet1|192.168.254.$IP4ADDR/24" \
defaultrouter=192.168.254.1 \
resolver="nameserver 192.168.254.1" \
allow_raw_sockets=1 \
boot=on \
ip6_addr="vtnet1|2001:470:24:8b:1::$IP6ADDR" \
defaultrouter6="vtnet1|2001:470:24:8b:1::1" \
exec_poststart="/usr/bin/env iocage exec $JNAME '/usr/sbin/service -R'"

#lets encryptの証明書を共有する
mkdir -p /iocage/jails/$JNAME/root/usr/local/etc/lets-ssl
iocage fstab $JNAME -a "/usr/local/etc/lets-ssl /usr/local/etc/lets-ssl nullfs rw 0 0"
iocage restart $JNAME
