This session will cover a Hands-on to pack some small modules of nodejs for Debian and make a .deb out of it, I will also cover some tools like npm2deb and other tools like lintian.

4. Agenda
● What is meant by Debian packaging ?
● Packaging workflow
● How to get started.
- Requirements
● Packaging a simple Nodejs module

5. What is Debian packaging
We all do is sudo apt install <package name>
Wondered how apt install works and what file it fetches and how the file gets
auto installed ??
So , here comes the Debian Packaging task.
The aim of packaging is to allow the automation of installing, upgrading,
configuring, and removing computer programs for Debian in a consistent
manner.
To be simple , its like making .deb of any software or module like in windows we
have .exe file

6. The packaging work flow is usually like this:
● Step 1: Rename the upstream tarball
● Step 2: Unpack the upstream tarball
● Step 3: Add the Debian packaging files
● Step 4: Build the package
● Step 5: Install the package
Then you can test your package on your computer.
Packaging workflow

7. What are we going to do Today ?
So Today , we will be focusing on learning the basic structure of packages as
well as knowing the tools used for this purpose.
A handson of making a package from scratch .
I will be using a simple nodejs module for the work today.
Enough of this knowledge , get me to the coding part and lets do the
packaging

8. Requirements
So , To start with Debian packaging , we need a Debian SID environment .
I have an ubuntu/arch/gentoo/mac machine and installing another OS , nah , not ready for a new
OS - its that's what you are thinking now , don’t worry we have Docker , lxc or virtual machine for
you .
Today i will be using Docker container to do the same.
Install packaging tools inside the container
dh-make-golang ,gem2deb ,npm2deb (These tools depend on module to module which we want to
package , But dh-make is a generic one)
Essential tools :-
git-buildpackage ,sbuild ,dh-buildinfo, quilt,

9. installation of Docker SID environment
Pull Debian Sid image from docker hub using the following command docker pull debian:sid
Create a container with it and start bash on it using docker run - -privileged - -name “sid” -it
debian:sid /bin/bash
Update and upgrade to latest versions of packages using apt-get update && apt-get upgrade
If you need to connect to it later, use the following commands which will take you to the bash
prompt.
“sudo docker start sid && sudo docker attach sid”

10. Let’s do a demo!
