Introduction

Hey there, little buddy! Today, we’re going to learn about Docker commands. Docker is a tool that helps you run and manage programs in special “containers.” These containers make it easy to work with different software without needing to install everything on your computer. Let’s explore some of the most useful Docker commands!

Basic Commands

1. docker version: This command shows you the version of Docker you have installed. It’s like checking if your toy is a new model or an older one.

docker version

2. docker info: This command gives you information about your Docker setup, like how much space it uses.

docker info

3. docker ps: This command shows you a list of all the containers that are currently running. It’s like seeing all your friends who are playing with you right now!

docker ps

Building Images

Docker images are like special blueprints for your containers. They have everything needed to run a program. Here are some important commands to work with Docker images:

1. docker build: This command helps you create a new Docker image from a recipe called a “Dockerfile.” It’s like building a toy from instructions!

docker build -t *your_image_name* .

Replace “your_image_name” with the name you want to give your new image. The dot (.) at the end tells Docker to use the current directory as the build location.

2. docker images: This command shows you a list of all the Docker images you have on your computer, like seeing all the toys you own!

Working With Containers

Now let’s learn some commands to work with containers:

1. docker run: This command starts a new container from one of your Docker images. You can think of it like inviting a friend to play!

docker run -t -i *your_image_name*

Replace “your_image_name” with the name of the image you want to use. The -t and -i flags tell Docker to give your container a virtual terminal and keep it interactive, like playing a game where you can see what’s happening inside!

2. docker start: This command starts a container that is already stopped, like waking up a sleeping friend.

docker start *container_id*

Replace “container_id” with the ID of the container you want to start.

3. docker stop: This command stops a running container, like telling your friend it’s time for a nap.

docker stop *container_id*

Replace “container_id” with the ID of the container you want to stop.
