Homeassistant in jail?

maybe something like this (from chapter 22 of Abs. FreeBSD 3)…

• Add another IP address (alias) in /etc/rc.conf, e.g.:

  ifconfig_re0_alias0="inet 192.168.0.205/32"
  

• Enable jails in /etc/rc.conf:

  jail_enable=YES
  

That’ll start everything in /etc/jail.conf at boot time, good enough for now.

• Download base.txz if I don’t have it already:

  curl http://ftp.freebsd.org/pub/FreeBSD/releases/amd64/13.0-RELEASE/base.txz
  

• Make a dir for the jail:

  mkdir -p /jails/ha.home
  

• Unpack base there:

  tar -xpf base.txz -C /jails/ha.home
  

• Create or add to /etc/jail.conf:

  ha {
    host.hostname="ha.home";
    ip4.addr="192.168.0.205";
    path="/jails/ha.home";
    mount.devfs;
    exec.clean;
    exec.start="sh /etc/rc";
    exec.stop="sh /etc/rc.shutdown";
  }
  

• copy some things from the host:

  cp /etc/resolv.conf /etc/localtime /jails/ha.home/etc
  touch /jail/ha.home/etc/fstab
  

• Create /jails/ha.home/etc/rc.conf:

  sendmail_enable="NO"
  sendmail_submit_enable="NO"
  sendmail_outbound_enable="NO"
  sendmail_msp_queue_enable="NO"
  syslogd_enable="NO"
  cron_enable="NO"
  

• Try starting it, then stopping it:

  jail -c ha
  jls
  jexec ha ps -ax
  jexec ha /bin/sh
  jail -r ha
  

• Back on the host, do some package installs into the jail:

  jail -c ha
  pkg -j ha install rust py38-pip py38-sqlite3 jpeg-turbo
  

(Yes, you have to install a whole additional language, Rust, in order to build the Python cryptography package. Sigh.)

• Install homeassistant in the system:

  jexec ha pip-3.8 install homeassistant
  

• Start it running:

  jexec ha hass
  

Give it a few minutes, then try going to http://192.168.0.205:8123 to continue setting it up.
