1. Key Docker Concepts

In this section, we'll explore the fundamental concepts of Docker - a powerful tool for managing containers. Understanding these concepts will help you gain a deeper insight into how Docker works and how to effectively utilize it in your software development and deployment processes.

What is Docker?

Containers, Dockerfile and Docker Commands

Installing the Docker Desktop

2. Quick Start

This section will guide you step by step through the process of creating your first Dockerfiles - text files that contain instructions for automating the building of Docker images. You will learn how to create a Dockerfile for your application, including defining the base image, adding necessary components, configuring the environment, and installing dependencies.

PostgreSQL Image

The PostgreSQL image in Docker allows you to run and utilize PostgreSQL databases within a containerized environment. Docker is a platform for deploying software applications in virtual containers, providing an easy way to create, deploy, and manage containers. The PostgreSQL image in Docker provides a standardized way to deploy and use this database, as well as enabling easy scalability and management of container images.

It's a command for the package manager of Alpine Linux, which is used as the base image in Docker.

This command adds the specified packages to the Docker image during its build, so they are available inside containers based on this image.

Other Databases

Here are similar commands for installing other databases:

For MySQL:

For MongoDB (you may also need to install the libbson library):

For SQLite:

These commands will install the necessary packages for working with the respective database on Alpine Linux. You may also need to install other additional packages or configure the environment depending on your specific use case.

Instructions for installing these and other images can be found on Docker Hub.
