Getting Started With Bastille BSD - Step by Step Guide
Getting Started with BastileBSD: A Step-by-Step Guide
BastileBSD is a powerful tool for managing FreeBSD jails, designed to simplify the process of setting up and maintaining chroots or jails. Whether you're new to FreeBSD or looking to streamline your jail management, BastileBSD offers a robust solution. In this guide, we'll walk you through the process of getting started with BastileBSD, from installation to creating your first jails.

Introduction to BastileBSD
BastileBSD is a shell script-based tool that automates the creation and management of FreeBSD jails. It supports various types of jails, including standard, VNET, bridged, and thick jails, making it versatile for different use cases. The tool is well-documented, and its documentation is automatically updated with each commit, ensuring you always have access to the latest information.

Installing BastileBSD
Before you can start using BastileBSD, you need to install it on your system. There are a few ways to install BastileBSD:
1. **Install from Packages**
If you prefer using pre-built packages, you can install BastileBSD using the FreeBSD package manager:
```bash
sudo pkg install bastille
```
This will install version 0.13 of BastileBSD.
### 2. **Install from Ports**
If you want to build BastileBSD from source, you can use the FreeBSD Ports system:
```bash
sudo make -C /usr/ports/security/bastille install
```
### 3. **Install from Git**
For the latest, unreleased version of BastileBSD, you can clone the repository from Git:
```bash
sudo git clone https://github.com/bastillebsd/bastille.git /usr/local/bastille
sudo make -C /usr/local/bastille install
```
This method is recommended if you want to stay on the bleeding edge of development.

Setting Up BastileBSD
Once installed, you need to set up BastileBSD before you can start creating jails.
### 1. **Initialize BastileBSD**
Run the following command to initialize BastileBSD and create the necessary configuration files:
```bash
sudo bastille setup
```
This will create a default configuration file at `/usr/local/etc/bastille/bastille.conf`.
### 2. **Configure ZFS (Optional)**
If your system uses ZFS, you need to configure BastileBSD to work with ZFS. Open the configuration file in your preferred editor:
```bash
sudo nano /usr/local/etc/bastille/bastille.conf
```
Locate the ZFS section and set the following options:
```bash
zfs = "yes"
zfspool = "zroot"
```
Replace `zroot` with the name of your ZFS pool if it's different.
---
Bootstrapping BastileBSD
Before you can create jails, you need to bootstrap BastileBSD with a FreeBSD release. Bootstrapping downloads and prepares the base system for the specified release.
1. **Bootstrap a Release**
To bootstrap a release, use the following command:
```bash
sudo bastille bootstrap 14.2-RELEASE
```
Replace `14.2-RELEASE` with the version of FreeBSD you want to use. Valid options include `14.2-RELEASE`, `13.5-RELEASE`, and `13.4-RELEASE`.
The bootstrapping process will:
- Download the base system (base.txz)
- Validate the checksum of the downloaded file
- Extract the base system to the appropriate location
2. **Verify the Bootstrapped Release**
After the bootstrapping process is complete, you can verify the release with:
```bash
sudo bastille list releases
```
This command will show you all the releases you have bootstrapped.

Creating Jails with BastileBSD
Now that BastileBSD is set up and bootstrapped, you can start creating jails. BastileBSD supports several types of jails, including standard, VNET, bridged, and thick jails.
1. **Create a Standard Jail**
A standard jail is a thin jail that shares the base system with the host. To create a standard jail, use the following command:
```bash
sudo bastille create myjail 14.2-RELEASE 10.0.0.1
```
- `myjail`: The name of the jail.
- `14.2-RELEASE`: The release to use for the jail.
- `10.0.0.1`: The IP address for the jail.
By default, BastileBSD will create a thin jail. Thin jails are lightweight and share the base system with the host.
2. **Create a VNET Jail**
A VNET jail is a thick jail that has its own network stack and can be bridged to a physical interface. To create a VNET jail, use the following command:
```bash
sudo bastille create -V myvnetjail 14.2-RELEASE
```
- `-V`: Enable VNET for the jail.
- `myvnetjail`: The name of the jail.
- `14.2-RELEASE`: The release to use for the jail.
BastileBSD will automatically configure the network interfaces for the VNET jail.
3. **Create a Bridged Jail**
A bridged jail is connected to a physical network interface on the host. To create a bridged jail, use the following command:
```bash
sudo bastille create -b mybridgejail 14.2-RELEASE
```
- `-b`: Enable bridged mode for the jail.
- `mybridgejail`: The name of the jail.
- `14.2-RELEASE`: The release to use for the jail.
4. **Create a Thick Jail**
A thick jail is a self-contained jail that includes its own copy of the base system. To create a thick jail, use the following command:
```bash
sudo bastille create -T mythickjail 14.2-RELEASE
```
- `-T`: Enable thick mode for the jail.
- `mythickjail`: The name of the jail.
- `14.2-RELEASE`: The release to use for the jail.

Managing Jails with BastileBSD
Once you've created your jails, you can manage them using various BastileBSD commands.
1. **List Jails**
To list all the jails on your system, use:
```bash
sudo bastille list
```
For more detailed information, use:
```bash
sudo bastille list all
```
2. **Start, Stop, and Restart Jails**
You can control the state of your jails with the following commands:
- Start a jail:
```bash
sudo bastille start myjail
```
- Stop a jail:
```bash
sudo bastille stop myjail
```
- Restart a jail:
```bash
sudo bastille restart myjail
```
3. **Update Jails**
To update a bootstrapped release and apply security patches to thin jails, use:
```bash
sudo bastille update 14.2-RELEASE
```
Note that thick jails need to be updated manually.

Additional Resources
- **Documentation**: The BastileBSD documentation is extensive and covers everything from basic usage to advanced topics like networking and templates. You can find it at bastillebsd.org
(https://bastillebsd.org/).
- **Templates**: BastileBSD supports templates, which allow you to create multiple jails with the same configuration. This topic will be covered in a future video.
- **Linux Jails**: BastileBSD also supports Linux jails, though this feature is still experimental.
