Working with and Using Docker CLI

Hello friends, today we want to talk about Docker and its Command Line Interface (CLI). Docker is recognized as a powerful platform for creating and managing containers. By using Docker, you can easily build and develop your applications in a streamlined manner. However, how can CLI Docker be utilized? This is the question we will address in the following.

First of all, it's important to understand what tasks Docker CLI actually performs. By utilizing CLI, you can create containers, manage them, and easily interact with your applications within those containers. This tool allows you to seamlessly configure different environments and efficiently manage applications that run within containers. This tool enables you to easily replicate different environments and test your applications under various scenarios.

To get started, you will need to install Docker on your system. You can perform this task from the official Docker website. After installation, you can begin working with Docker using simple CLI commands. For example, the command docker run is used to launch a new container based on a specific image and you can view the running containers with the command docker ps.

In summary, one of the key benefits of Docker is the ease of managing your own containers. This means that you can easily launch multiple versions of an application and manage the traffic between them. Now, let's take a look at some basic Docker commands.

Basic Docker Commands

# Launching a new container from a specific image
docker run -d --name my_container nginx

# Viewing the list of running containers
docker ps

# Stopping a running container
docker stop my_container

# Removing a container
docker rm my_container

Command Descriptions

Launching a new container from a specific image: By using the command docker run -d --name my_container nginx, we can launch a new container named my_container from the image nginx.
Viewing the list of running containers: With the command docker ps, we can see which containers are currently running.
Stopping a running container: To stop an active container, we use the command docker stop my_container.
Removing a container: If we want to remove a container, we can utilize the command docker rm my_container.
