Docker Guide for AI Model Development and Deployment

This repo is divided into two parts:

  1. The theoretical concept of the Docker and
  2. Examples to get started with Docker.

The following is theoretical concepts of the Docker with hands-ons commands.

Chapter 1: Understanding Docker Containers

1.1 What are Docker Containers?

Docker containers are lightweight, standalone, executable packages that include everything needed to run a piece of software, including the code, runtime, system tools, system libraries, and settings. Containers are isolated from each other and the host system, yet they share the OS kernel of the host machine, which makes them more efficient than traditional virtual machines.

1.2 What is the difference between a container and VM?

Containers and virtual machines have similar resource isolation and allocation benefits, but function differently because containers virtualize the operating system instead of hardware. Containers are more portable and efficient.

Containers are an abstraction at the app layer that packages code and dependencies together. Multiple containers can run on the same machine and share the OS kernel with other containers, each running as isolated processes in user space. Containers take up less space than VMs (container images are typically tens of MBs in size), can handle more applications and require fewer VMs and Operating systems.

Virtual machines (VMs) are an abstraction of physical hardware turning one server into many servers. The hypervisor allows multiple VMs to run on a single machine. Each VM includes a full copy of an operating system, the application, necessary binaries and libraries – taking up tens of GBs. VMs can also be slow to boot.

1.5 Key Docker Concepts for AI

This is a basic outline for Chapter 1. For the complete guide, you would need to continue with detailed content for each subsequent chapter, incorporating code snippets, best practices, and real-world examples, especially those relevant to AI and machine learning.

Chapter 2: Setting Up Docker

This chapter provides a comprehensive guide on installing Docker and introduces some basic Docker commands essential for AI and machine learning applications.

2.1 Installation Guide for Different Operating Systems

2.1.1 Installing Docker on Linux

  1. Ubuntu: Use apt-get to install Docker.

  2. or follow the given commands for the Linux installation (same installation given in bash file sudo ./docker_install.sh) or execute the following commands one by one.

     # Uuninstall all conflicting packages
 for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

 # Add Docker's official GPG key:
 sudo apt-get update
 sudo apt-get install ca-certificates curl gnupg
 sudo install -m 0755 -d /etc/apt/keyrings
 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
 sudo chmod a+r /etc/apt/keyrings/docker.gpg

 # Add the repository to Apt sources:
 echo \
 "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
 "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
 sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
 sudo apt-get update

 # Install the latest version,
 sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

 # Verify that the Docker Engine installation
 sudo docker run hello-world

    At the end you should see the output like this:

     Hello from Docker!
 This message shows that your installation appears to be working correctly.

 To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
     (amd64)
 3. The Docker daemon created a new container from that image which runs the
     executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
     to your terminal.

 To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

 Share images, automate workflows, and more with a free Docker ID:
 https://hub.docker.com/
