use a docker

Docker is a popular platform esteemed for its ability to simplify the process of creating, deploying and running applications by using containers. This article takes you through a simplified step by-step tutorial on how to use Docker.

A Simple Introduction

Firstly, Docker requires installation. Visit the official Docker website and download the version that corresponds with your operating system, be it Ubuntu, Windows or MacOS.

Step 1: Docker Installation

Once the download is complete, proceed to install Docker. If you encounter any problems, Docker’s installation manual can be a helpful resource.

Step 2: Confirm Docker Installation

It’s important to confirm Docker has been installed correctly. Open your terminal and type docker run hello-world. This command tells Docker to run the ‘hello-world’ container. If everything works as expected, you’ll receive a message that Docker is functioning correctly.

Step 3: Search for Available Docker Images

Docker images are the key component that allow applications to run in different Docker containers. To find one, simply type: docker search <Name_Of_Container>.

Step 4: Pull Docker Images

By using the command docker pull <Name_Of_Container>, you can download Docker images for your containers. Use any image name you prefer, for example, Ubuntu.

Step 5: Run the Docker Container

After pulling a Docker image, it’s time to run it inside a container. This is achievable by typing in the command docker run -it <Name_Of_Container>. The -it option opens up an interactive terminal inside the container.

Step 6: List Docker Containers

If you need to see a list of your active Docker containers, type docker ps. For a list that includes both active and inactive ones, use docker ps -a.

Step 7: Stop Docker Containers

Stopping a container is easy. Simply type docker stop <Container_ID> and replace <Container_ID> with your desired container’s ID.

Step 8: Remove Docker Containers

Sometimes you might need to remove a container from your system. If that’s the case, type docker rm <Container_ID> and the container will be deleted.

Conclusively, Docker is an essential tool, especially for developers. With this guide, even individuals with little or no prior Docker knowledge should be able to navigate the process without hassle. The road to mastering Docker begins with mastering these steps. Practice them until you’re comfortable, and happy docking!
