## 0.4-beta
This document outlines the basic usage of the Bastille jail management
framework. This release is still considered beta.


Network Requirements
====================
Several networking options can be performed regarding the user needs.
Basic jails can support IP alias networking, where the IP address is assigned
to the host interface and used by the jail, generally known as "shared IP" based jails.

However, in order to segregate jails from the network and from the world, Bastille
attaches jails to a loopback interface only. The host system then acts as
the firewall, permitting and denying traffic as needed.

First, create the loopback interface:

```shell
ishmael ~ # sysrc cloned_interfaces+=lo1
ishmael ~ # sysrc ifconfig_lo1_name="bastille0"
ishmael ~ # service netif cloneup
ishmael ~ # ifconfig bastille0 inet 10.17.89.10
```

Second, enable the firewall:

```shell
ishmael ~ # sysrc pf_enable="YES"
```

Create the firewall config, or merge as necessary.

/etc/pf.conf
------------
```
ext_if="vtnet0"

set block-policy drop
scrub in on $ext_if all fragment reassemble

set skip on lo
nat on $ext_if from bastille0:network to any -> ($ext_if)

## rdr example
## rdr pass inet proto tcp from any to any port {80, 443} -> 10.17.89.45

block in log all
pass out quick modulate state
antispoof for $ext_if inet
pass in inet proto tcp from any to any port ssh flags S/SA keep state
```

* Make sure to change the `ext_if` variable to match your host system interface.
* Make sure to include the last line (`port ssh`) or you'll end up locked
out.

Note: if you have an existing firewall, the key lines for in/out traffic to jails are:

```
nat on $ext_if from bastille0:network to any -> ($ext_if)

## rdr example
## rdr pass inet proto tcp from any to any port {80, 443} -> 10.17.89.45
```

The `nat` routes traffic from the loopback interface to the external interface
for outbound access.

The `rdr pass ...` will redirect traffic from the host firewall on port X to
the ip of Jail Y. The example shown redirects web traffic (80 & 443) to the
jails at `10.17.89.45`.

We'll get to that later, but when you're ready to allow traffic inbound to your
jails, that's where you'd do it.

Finally, start up the firewall:

```shell
ishmael ~ # service pf restart
```

At this point you'll likely be disconnected from the host. Reconnect the ssh
session and continue.

This step only needs to be done once in order to prepare the host.


ZFS support
===========

![BastilleBSD Twitter Poll](/docs/images/bastillebsd-twitter-poll.png)

Bastille 0.4 added initial support for ZFS. `bastille bootstrap` and `bastille
create` will generate ZFS volumes based on settings found in the
`bastille.conf`. This section outlines how to enable and configure Bastille for
ZFS.

Two values are required for Bastille to use ZFS. The default values in the
`bastille.conf` are empty. Populate these two to enable ZFS.

```shell
## ZFS options
bastille_zfs_enable=""                                  ## default: ""
bastille_zfs_zpool=""                                   ## default: ""
bastille_zfs_prefix="bastille"                          ## default: "${bastille_zfs_zpool}/bastille"
bastille_zfs_mountpoint=${bastille_prefix}              ## default: "${bastille_prefix}"
bastille_zfs_options="-o compress=lz4 -o atime=off"     ## default: "-o compress=lz4 -o atime=off"
```

**Example**

```shell
ishmael ~ # sysrc -f /usr/local/etc/bastille/bastille.conf bastille_zfs_enable=YES
ishmael ~ # sysrc -f /usr/local/etc/bastille/bastille.conf bastille_zfs_zpool=ZPOOL_NAME
```

Replace `ZPOOL_NAME` with the zpool you want Bastille to use. Tip: `zpool list`
and `zpool status` will help.


bastille bootstrap
------------------
Before you can begin creating jails, Bastille needs to "bootstrap" a release.
Current supported releases are 11.2-RELEASE and 12.0-RELEASE, but you can
bootstrap anything in the ftp.FreeBSD.org RELEASES directory.

**Important: If you need ZFS support see the above section BEFORE bootstrapping.**

Note: your mileage may vary with unsupported releases and releases newer than
the host system likely will NOT work at all.

To `bootstrap` a release, run the bootstrap sub-command with the
release version as the argument.


** FreeBSD 12.0-RELEASE **
```shell
ishmael ~ # bastille bootstrap 12.0-RELEASE
```

** FreeBSD 11.2-RELEASE **
```shell
ishmael ~ # bastille bootstrap 11.2-RELEASE
```

** HardenedBSD 12-STABLE-LAST **
```shell
ishmael ~ # bastille bootstrap 12-STABLE-LAST
```

** HardenedBSD 11-STABLE-LAST **
```shell
ishmael ~ # bastille bootstrap 11-STABLE-LAST
```

This command will ensure the required directory structures are in place and
download the requested release. For each requested release, `bootstrap` will
download the base.txz. If you need more than base (eg; ports, lib32, src) you
can configure the `bastille_bootstrap_archives` in the configuration file. By
default this value is set to "base". Additional components are added, space
separated, without extension.

Bastille will attempt to fetch the required archives if they are not found in
the `cache/$RELEASE` directory. 

Downloaded artifacts are stored in the `cache/$RELEASE` directory. "bootstrapped"
releases are stored in `releases/$RELEASE`.

Advanced: If you want to create your own custom base.txz, or use an unsupported
variant of FreeBSD, drop your own base.txz in `cache/$RELEASE/base.txz` and
`bastille bootstrap` will attempt to extract and use it.

The bootstrap subcommand is generally only used once to prepare the system. The
other use cases for the bootstrap command are when a new FreeBSD version is
released and you want to start building jails on that version, or bootstrapping
templates from GitHub or GitLab.

See `bastille update` to ensure your bootstrapped releases include the latest
patches.


bastille create
---------------
`bastille create` uses a bootstrapped release to create a lightweight
jailed system. To create a jail simply provide a name, release and
a private (rfc1918) IP address.

- name
- release (bootstrapped)
- ip


```shell
ishmael ~ # bastille create folsom 12.0-RELEASE 10.17.89.10

RELEASE: 12.0-RELEASE.
NAME: folsom.
IP: 10.17.89.10.
```

This command will create a 12.0-RELEASE jail assigning the 10.17.89.10 ip
address to the new system.

Optionally `bastille create [ -T | --thick ]` will create a self contained Thickjail system instead.

```shell
ishmael ~ # bastille create -T folsom 12.0-RELEASE 10.17.89.10
```

I recommend using private (rfc1918) ip address ranges for your jails.
These ranges include:

- 10.0.0.0/8
- 172.16.0.0/12
- 192.168.0.0/16

If your Bastille host also uses private (rfc1918) addresses, use a different
range for your jails. ie; Host uses 192.168.0.0/16, jails use 10.0.0.0/8.

Bastille does its best to validate the submitted ip is valid. This has not been
thouroughly tested. I generally use the 10.0.0.0/8 range for jails.


bastille start
--------------
To start a jail you can use the `bastille start` command.

```shell
ishmael ~ # bastille start folsom
[folsom]:
folsom: created

```


bastille stop
-------------
To stop a jail you can use the `bastille stop` command.

```shell
ishmael ~ # bastille stop folsom
[folsom]:
folsom: removed

```


bastille restart
----------------
To restart a jail you can use the `bastille restart` command.

```shell
ishmael ~ # bastille restart folsom
[folsom]:
folsom: removed

[folsom]:
folsom: created

```


bastille service
----------------
To restart services inside a jail you can use the `bastille service` command.

```shell
ishmael ~ # bastille service folsom 'postfix restart'
[folsom]
postfix/postfix-script: stopping the Postfix mail system
postfix/postfix-script: starting the Postfix mail system

```


bastille cmd
------------
To execute commands within the jail you can use `bastille cmd`.

```shell
ishmael ~ # bastille cmd folsom 'ps -auxw'
[folsom]:
USER   PID %CPU %MEM   VSZ  RSS TT  STAT STARTED    TIME COMMAND
root 71464  0.0  0.0 14536 2000  -  IsJ   4:52PM 0:00.00 /usr/sbin/syslogd -ss
root 77447  0.0  0.0 16632 2140  -  SsJ   4:52PM 0:00.00 /usr/sbin/cron -s
root 80591  0.0  0.0 18784 2340  1  R+J   4:53PM 0:00.00 ps -auxw

```


bastille pkg
------------
To manage binary packages within the jail use `bastille pkg`.

```shell
ishmael ~ # bastille pkg folsom 'install vim-console git-lite zsh'
[folsom]:
The package management tool is not yet installed on your system.

The PKG sub-command can, of course, do more than just `install`. The
expectation is that you can fully leverage the pkg manager. This means,
`install`, `update`, `upgrade`, `audit`, `clean`, `autoremove`, etc.

```


bastille destroy
----------------
Jails can be destroyed and thrown away just as easily as they were created.
Note: jails must be stopped before destroyed.

```shell
ishmael ~ # bastille stop folsom
[folsom]:
folsom: removed

ishmael ~ # bastille destroy folsom
Deleting Jail: folsom.
Note: jail console logs not destroyed.
/usr/local/bastille/logs/folsom_console.log

```

bastille template
-----------------
Bastille supports a templating system allowing you to apply files, pkgs and
execute commands inside the jail automatically.

Currently supported template hooks are: `PRE`, `CONFIG`, `PKG`, `SYSRC`, `CMD`.
Planned template hooks include: `FSTAB`, `PF`, `LOG`

Templates are created in `${bastille_prefix}/templates` and can leverage any of
the template hooks. Simply create a new directory named after the template. eg;

```shell
mkdir -p /usr/local/bastille/templates/base
```

To leverage a template hook, create an UPPERCASE file in the root of the
template directory named after the hook you want to execute. eg;

```shell
echo "zsh vim-console git-lite htop" > /usr/local/bastille/templates/base/PKG
echo "/usr/bin/chsh -s /usr/local/bin/zsh" > /usr/local/bastille/templates/base/CMD
echo "etc root usr" > /usr/local/bastille/templates/base/CONFIG
```

Template hooks are executed in specific order and require specific syntax to
work as expected. This table outlines those requirements:

| SUPPORTED | format           | example                                                        |
|-----------|------------------|----------------------------------------------------------------|
| PRE/CMD   | /bin/sh command  | /usr/bin/chsh -s /usr/local/bin/zsh                            |
| OVERLAY   | paths (one/line) | etc root usr                                                   |
| PKG       | port/pkg name(s) | vim-console zsh git-lite tree htop                             |
| SYSRC     | sysrc command(s) | nginx_enable=YES                                               |

| PLANNED | format           | example                                                        |
|---------|------------------|----------------------------------------------------------------|
| PF      | pf rdr entry     | rdr pass inet proto tcp from any to any port 80 -> 10.17.89.80 |
| LOG     | path             | /var/log/nginx/access.log                                      |
| FSTAB   | fstab syntax     | /path/on/host /path/in/jail nullfs ro 0 0                      |

Note: SYSRC requires NO quotes or that quotes (`"`) be escaped. ie; `\"`)

In addition to supporting template hooks, Bastille supports overlaying files
into the jail. This is done by placing the files in their full path, using the
template directory as "/".

An example here may help. Think of `/usr/local/bastille/templates/base`, our
example template, as the root of our filesystem overlay. If you create an
`etc/hosts` or `etc/resolv.conf` *inside* the base template directory, these
can be overlayed into your jail.

Note: due to the way FreeBSD segregates user-space, the majority of your
overlayed template files will be in `usr/local`. The few general
exceptions are the `etc/hosts`, `etc/resolv.conf`, and `etc/rc.conf.local`.

After populating `usr/local/` with custom config files that your jail will
use, be sure to include `usr` in the template CONFIG definition. eg;

```shell
echo "etc" > /usr/local/bastille/templates/base/OVERLAY
echo "usr" >> /usr/local/bastille/templates/base/OVERLAY
```

The above example will include anything under "etc" and "usr" inside
the template. You do not need to list individual files. Just include the
top-level directory name.


Applying Templates
------------------

Jails must be running to apply templates.

Bastille includes a `template` sub-command. This sub-command requires a target
and a template name. As covered in the previous section, template names
correspond to directory names in the `bastille/templates` directory.

```shell
ishmael ~ # bastille template folsom base
[folsom]:
Copying files...
Copy complete.
Installing packages.
...[snip]...
Executing final command(s).
chsh: user information updated
Template Complete.

```


bastille top
------------
This one simply runs `top` in that jail. This command is interactive, as `top`
is interactive.


bastille htop
-------------
This one simply runs `htop` inside the jail. This one is a quick and dirty
addition. note: won't work if you don't have htop installed in the jail.


bastille sysrc
--------------
The `sysrc` sub-command allows for safely editing system configuration files.
In jail terms, this allows us to toggle on/off services and options at
startup.

```shell
ishmael ~ # bastille sysrc nginx nginx_enable=YES
[nginx]:
nginx_enable: NO -> YES
```

See `man sysrc(8)` for more info.


bastille console
----------------
This sub-command launches a login shell into the jail. Default is

root@folsom:~ #
```

At this point you are logged in to the jail and have full shell access.
The system is yours to use and/or abuse as you like. Any changes made inside
the jail are limited to the jail. 


bastille cp
-----------
Note: this sub-command may need a little work. 

This sub-command allows efficiently copying files from host to jail(s).

```shell
ishmael ~ # bastille cp ALL /tmp/resolv.conf-cf etc/resolv.conf
[bastion]:

[unbound0]:

[unbound1]:

[squid]:

[nginx]:

[folsom]:

```

Unless you see errors reported in the output the `cp` was successful.


bastille list
-------------
This sub-command will show you the running jails on your system.

```shell
ishmael ~ # bastille list
 JID             IP Address      Hostname                      Path
 bastion         10.17.89.65      bastion                       /usr/local/bastille/jails/bastion/root
 unbound0        10.17.89.60      unbound0                      /usr/local/bastille/jails/unbound0/root
 unbound1        10.17.89.61      unbound1                      /usr/local/bastille/jails/unbound1/root
 squid           10.17.89.30      squid                         /usr/local/bastille/jails/squid/root
 nginx           10.17.89.45      nginx                         /usr/local/bastille/jails/nginx/root
 folsom          10.17.89.10      folsom                        /usr/local/bastille/jails/folsom/root
```


bastille update
---------------
The `update` command targets a release instead of a jail. Because every
jail is based on a release, when the release is updated all the jails are
automatically updated as well.

To update all jails based on the 11.2-RELEASE `release`:

Up to date 11.2-RELEASE:
```shell
ishmael ~ # bastille update 11.2-RELEASE
Targeting specified release.
11.2-RELEASE

Looking up update.FreeBSD.org mirrors... 2 mirrors found.
Fetching metadata signature for 11.2-RELEASE from update4.freebsd.org... done.
Fetching metadata index... done.
Inspecting system... done.
Preparing to download files... done.

No updates needed to update system to 11.2-RELEASE-p4.
No updates are available to install.
```

Updating 10.4-RELEASE:
```shell
ishmael ~ # bastille update 10.4-RELEASE
Targeting specified release.
10.4-RELEASE

Looking up update.FreeBSD.org mirrors... 2 mirrors found.
Fetching metadata signature for 10.4-RELEASE from update1.freebsd.org... done.
Fetching metadata index... done.
Fetching 2 metadata patches.. done.
Applying metadata patches... done.
Fetching 2 metadata files... done.
Inspecting system... done.
Preparing to download files... done.

The following files will be added as part of updating to 10.4-RELEASE-p13:
...[snip]...
```

To be safe, you may want to restart any jails that have been updated
live.


bastille upgrade
----------------
This sub-command lets you upgrade a release to a new release. Depending on the
workflow this can be similar to a `bootstrap`.

```shell
ishmael ~ # bastille upgrade 11.2-RELEASE 12.0-RELEASE
...
```


bastille verify
---------------
This sub-command scans a bootstrapped release and validates that everything
looks in order. This is not a 100% comprehensive check, but it compares the
release against a "known good" index.

If you see errors or issues here, consider deleting and re-bootstrapping the
release.


bastille zfs
------------
This sub-command allows managing zfs attributes for the targeted jail(s).
Common usage includes setting jail quotas.

** set quota **
```shell
ishmael ~ # bastille zfs folsom 'set quota=1G'
```

** built-in: df **
```shell
ishmael ~ # bastille zfs ALL df
```

** built-in: df **
```shell
ishmael ~ # bastille zfs folsom df
```


Example (create, start, console)
================================
This example creates, starts and consoles into the jail.

```shell
ishmael ~ # bastille create alcatraz 11.2-RELEASE 10.17.89.7

RELEASE: 11.2-RELEASE.
NAME: alcatraz.
IP: 10.17.89.7.
```

```shell
ishmael ~ # bastille start alcatraz
[alcatraz]:
alcatraz: created
```

```shell
ishmael ~ # bastille console alcatraz
[alcatraz]:

Project Goals
=============
These tools are created initially with the mindset of function over form. I
want to simply prove the concept is sound for real work. The real work is a
sort of meta-jail-port system. Instead of installing the MySQL port directly on
a system, you would use Bastille to install the MySQL port within a jail
template built for MySQL. The same goes for DNS servers, and everything else in
the ports tree.

Eventually I would like to have Bastille templates created for popular
FreeBSD-based services. From Plex Media Servers to ad-blocking DNS resolvers.
From tiny SSH jails to dynamic web servers.

I don't want to tell you what you can and can't run within this framework.
There are no arbitrary limitations based on what I think may or may not be the
best way to design systems. This is not my goal.

My goal is to provide a secure framework where processes and services can run
isolated. I want to limit the scope and reach of bad actors. I want to severely
limit the target areas available to anyone that has (or has gained!) access.

Networking Tips
===============

Tip #1: 
-------
Ports and destinations can be defined as lists. eg;
```
rdr pass inet proto tcp from any to any port {80, 443} -> {10.17.89.45, 10.17.89.46, 10.17.89.47, 10.17.89.48}
```

This rule would redirect any traffic to the host on ports 80 or 443 and
round-robin between jails with ips 45, 46, 47, and 48 (on ports 80 or 443).


Tip #2: 
-------
Ports can redirect to other ports. eg;
```
rdr pass inet proto tcp from any to any port 8080 -> 10.17.89.5 port 80
rdr pass inet proto tcp from any to any port 8081 -> 10.17.89.5 port 8080
rdr pass inet proto tcp from any to any port 8181 -> 10.17.89.5 port 443
```

Tip #3:
-------
Don't worry too much about IP assignments.
Initially I spent time worrying about what IP addresses to assign. In the
end I've come to the conclusion that it _really_ doesn't matter. Pick *any*
private address and be done with it. These are all isolated networks. In the
end, what matters is you can map host:port to jail:port reliably, and we
can.
