-# Jailmaker

-## Advanced Networking
-
-These are notes on advanced networking setup you may want to try. Contributions are welcome!
-
-### Bridge Networking
-
-As an alternative to the default host networking mode, you may want to connect to a bridge interface instead and let the jail obtain its IP address via DHCP (although you may have to be patient for up to 20 seconds after the jail started for networking to work, [assigning the IP address is somehow slow](https://github.com/Jip-Hop/jailmaker/issues/7)).
-
-[This YouTube video](https://www.youtube.com/watch?v=7clQw132w58) may be helpful when setting up the bridge interface. Note: You may lock yourself out... It may take several tries... TrueNAS is a bit picky when switching IP addresses and toggling DHCP. May be helpful to connect a monitor and keyboard to the NAS and use `/etc/netcli` to reset the networking interface. Kept bothering with "Register Default Gateway" warning... I just clicked Cancel.
-
-Add the `--network-bridge=br1 --resolv-conf=bind-host` systemd-nspawn flag when asked for `Additional flags` during jail creation, or set it post-creation by [editing](./README.md#edit-jail-config) the `SYSTEMD_NSPAWN_USER_ARGS` variable inside the `config` file.
-
-The TrueNAS host and the jail will be able to communicate with each other as if the jail was just another device on the LAN. It will use the same DNS servers as the TrueNAS host because the `--resolv-conf=bind-host` option bind mounts the `/etc/resolv.conf` file from the host inside the jail. If you want to use the DNS servers advertised via DHCP, then check [DNS via DHCP](#dns-via-dhcp).
-
-To configure a **static IP** with our bridge interface, we need to edit the `80-container-host0.network` file located in `/etc/systemd/network`. Change the `[Network]` section to look like this:
-
-```ini
-[Network]
-DHCP=false
-Address=192.168.0.12/24
-Gateway=192.168.0.1
-LinkLocalAddressing=no
-LLDP=yes
-EmitLLDP=customer-bridge
-```
-Then restart the `systemd-networkd` service and check your network configuration.
-
-```shell
-systemctl restart systemd-networkd
-systemctl status systemd-networkd
-ifconfig
-```
-
-
-### Macvlan Networking
-
-To setup Macvlan Networking you may follow the [Bridge Networking](#bridge-networking) section, but skip the setup of a bridge interface and use these flags instead: `--network-macvlan=eno1 --resolv-conf=bind-host`. By default the TrueNAS host and jail will not be able to communicate with each other via the network if Macvlan Networking mode is used. If that's required it would be better to use [Bridge Networking](#bridge-networking).
-
-### DNS via DHCP
-
-If you're not using host networking, and you're not using the `--resolv-conf=` in case of bridge/macvlan networking, then you have to configure the DNS servers to use.
-
-To get DNS servers via DHCP install and enable `resolvconf`.
-
-```shell
-# Only run this inside the jail!
-
-# Temporarily fix DNS resolution,
-# otherwise we can't install packages
-echo 'nameserver 8.8.8.8' > /etc/resolv.conf
-# On debian based distro
-apt update && apt -y install resolvconf
-```

 ## Networking
 
-By default the jail will have full access to the host network. No further setup is required. You may download and install additional packages inside the jail. Note that some ports are already occupied by TrueNAS SCALE (e.g. 443 for the web interface), so your jail can't listen on these ports. This is inconvenient if you want to host some services (e.g. traefik) inside the jail. To workaround this issue when using host networking, you may disable DHCP and add several static IP addresses (Aliases) through the TrueNAS web interface.

 The rootfs image `jlmkr.py` downloads comes from the [Linux Containers Image server](https://images.linuxcontainers.org). These images are made for LXC. We can use them with systemd-nspawn too, although not all of them work properly. For example, the `alpine` image doesn't work well. If you stick with common systemd based distros (Debian, Ubuntu, Arch Linux...) you should be fine.
 
-## Tips & Tricks
-
-### Colorized bash prompt
-
-To visually distinguish between a root shell inside the jail and a root shell outside the jail, it's possible to colorize the shell prompt. When using a debian jail with the bash shell, you may run the following command to get a yellow prompt inside the jail (will be activated the next time you run `jlmkr shell myjail`):
-
-```bash
-echo "PS1='${debian_chroot:+($debian_chroot)}\[\033[01;33m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '" >> ~/.bashrc

+Add the `--network-bridge=br1 --resolv-conf=bind-host` systemd-nspawn flag when asked for `Additional flags` during jail creation, or set it post-creation by [editing](./README.md#edit-jail-config) the `SYSTEMD_NSPAWN_USER_ARGS` variable inside the `config` file.

 Do not bind your TrueNAS system directories (`/root` `/mnt` `/dev` `/bin` `/etc` `/home` `/var` `/usr` or anything else in the root directory) to your jail as this can cause TrueNAS to lose permissions and render your TrueNAS system unusable.
