Welcome to the containerization guide! This document will provide you with an overview of containerization and how it can be used to streamline your development and deployment processes.
What is Containerization?
Containerization is a lightweight alternative to traditional virtualization. It allows you to package an application and its dependencies into a single, portable container. This container can then be run on any compatible system, regardless of the underlying hardware or operating system.
Key Benefits of Containerization
- Portability: Containers can be run on any system that supports the container runtime.
- Consistency: Containers ensure that your application runs the same way in development, testing, and production environments.
- Scalability: Containers can be easily scaled up or down based on demand.
Getting Started with Containerization
To get started with containerization, you will need to install a container runtime on your system. Docker is the most popular container runtime, but there are others available, such as containerd and rkt.
Installing Docker
To install Docker on your system, please visit the Docker installation guide for detailed instructions.
Working with Containers
Once you have Docker installed, you can start working with containers by using the Docker CLI.
Creating a Container
To create a new container, you can use the docker run command. For example, to run a container with the official Nginx image, you would use the following command:
docker run -d --name my-nginx nginx
This command creates a new container running the official Nginx image and starts it in detached mode.
Managing Containers
You can manage your containers using the Docker CLI. Some common commands include:
docker ps: Lists running containers.docker stop: Stops a running container.docker rm: Removes a container.
