How to install Fabric on NetBSD

Fabric is a command-line tool that enables you to automate tasks, especially in deployment tasks. In this tutorial, we will guide you through the installation process for Fabric on NetBSD.

Prerequisites

Before starting, make sure you have the following requirements installed:

• NetBSD installed on your system
• Python 2.7 or Python 3.x installed
• pip installed

Installing Fabric

1. Open your terminal and run the following command to install Fabric:

pip install fabric

2. After running the command above, you need to check if Fabric was successfully installed. You can do this by running the following command:

fab --version

This command will show you the current version of Fabric installed on your system.

Creating a Fabric file

After you have installed Fabric, you can start creating your own Fabric file. A Fabric file is a Python script containing commands that you can execute by using Fabric.

1. Create a new file in your desired location with the .py extension, for example:

nano ~/fabfile.py

2. Add the following code to the file:

from fabric import task

@task
def hello(c):
    print("Hello, Fabric!")

3. Save and close the file.

Running Fabric commands

Now, you can execute commands using Fabric. The syntax of the command is as follows:

fab <task_name> [-H <host>] [-u <username>] [-p <password>] [-D] [-a] [--version] [-h]

• <task_name> is the name of the task you want to execute.
• -H <host> is the hostname or IP address of the remote host you want to execute the task on.
• -u <username> is the username used to log in to the remote host.
• -p <password> is the password used to log in to the remote host.
• -D is used for debugging.
• -a is used for prompting for a password for each host.
• --version shows the current version of Fabric.
• -h shows the help menu.

To execute the task we created earlier, run the following command:

fab hello

You should see the following output:

[localhost] Executing task 'hello'
Hello, Fabric!

Congratulations! You have successfully installed Fabric on NetBSD and created your first Fabric file. Now, you can start automating your repetitive deployment tasks using Fabric.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
