Top 11 Useful Docker Commands to Know

Docker, which bills itself as "a better way to build apps," is a fully accessible platform for developing apps and micro - services, according to its webpage. The catch is that Dockers provides OS level emulation, which allows you to put your software in a container automatically. Dockers are superior than virtual machines (VMs) because they eliminate the overhead of managing and running the latter. Your program and its components (i.e. the pre-requisite applications for its optimal operation) become mobile during all stages of development and evaluation by putting them in a container. Furthermore, the segregated applications minimize time-to-market by eliminating disputes, enabling team cooperation, and reducing time-to-market.

Corporations are actively searching for experts that have a strong understanding of Docker commands as the Docker container phenomenon has grown uncontrolled. As a result, we'll go over the Top 11 Docker Commands in this article.


What Is Docker?

Docker is a resource management system that allows developers to encapsulate an app and its components in a Docker Container for software development and deployment.

Docker automates boring configuration processes and is utilized across the design process for fast, simple, and portable desktop and cloud application development. Docker's end-to-end platform comprises user interfaces, command-line interfaces, APIs, and protection that are all designed to function collaboratively across the whole application delivery lifecycle.

How Do You Setup a Docker Locally?

  • Get the Docker Toolbox and a Docker edition.
  • Ensure your BIOS supports Virtualization Technologies, AMD-V, or KVM. 
  • Get the Oracle VirtualBox Extension Pack.
  • Execute the Setup


When Is It Necessary to Use Docker?

  • To execute your code locally on your laptop while duplicating the environment on your server
  • During various development phases (dev/test/QA), for Docker CI/CD
  • As a content management system and for releasing your app's OS to a team.

Now, let's look at some of the most commonly used Docker commands by developers.

How Do You Use a Docker?

The most significant benefit of virtual machines is that they produce snapshots that may be reverted to at any time. Docker containers provide lightweight process emulation by being OS agnostic and utilizing the Linux Kernel's capabilities. They're made using Docker images, similar to snapshots. A Docker file is being used to produce Docker images, which may be altered or used as is. 'libcontainer' is the default performance driver for docker containers. Docker Hub may be used to look for docker images and see how they were created.

  • To make a Docker container, enter the following command in the prompt to get the 'hello world' image —

hello world $ docker run

  • Use the command $ docker images to see how many images you have on your machine.
  • To explore the Docker Hub for an image, do $ docker search <image>.

Top 11 Useful Docker Commands

1. Docker Start

 Starts one or more stopped containers.

2. Docker Stop

Stops one or more running containers.

3. Docker Run

Runs a command in a new container.

4. Docker Build

Builds an image form a Docker file.

5. Docker Push

Pushes an image or a repository to a registry

6. Docker Pull

Pulls an image or a repository from a registry

7. Docker Search

Searches the Docker Hub for images.

8. Docker Commit

Creates a new image from a container’s changes.

9. Docker Attach

Attaches to a running container.

10. Docker Export

Exports a container’s filesystem as a tar archive.

11.Docker Exec

 Runs a command in a run-time container.

Examples of Using a Docker

  • By downloading Docker, you may run WordPress locally on your laptop without installing additional Apache, PHP, MySQL, or other software. To run Docker on a virtual machine, the Docker Toolbox produces a containerized version of Linux.

o Get the Docker Tool Box, which will run Oracle VirtualBox for you.

o In VirtualBox, install the Extension Pack.

o In the terminal, type $ docker run hello-world to see if your installation was successful.

o To install WordPress locally, look for a WordPress image on the Docker Hub.

  • Dockers may also be used to install DokuWiki.
  • SDN components may be tested using Dockers.

When You Should Avoid Using Docker?

None of the scenarios listed automatically render Docker ineffective for your project. However, if any of these apply to you, you should reconsider whether Docker is the ideal answer for your software development.

Consider whether Docker is right for you if:

  1. Your software application is a desktop program.
  2. Your project is small and straightforward.
  3. You only have one developer on your development team.
  4. You're looking for a way to make your application run faster.
  5. The majority of your development crew is MacBook users.


That was everything there was to know about Docker Commands.

Docker is really useful since it allows people to participate to the program without needing to worry on how to execute it. This has become an important aspect of software development. Docker is used for creation, testing, and installation because it is simple to manage. It has gained popularity in the software industry because to its mobility. That is to say, if your software works in development, it should function in production as well.

Docker commands include a plethora of useful options. Run the docker command name —help command to learn about other potential parameters.

We hope the 11 Docker commands given above will assist you in getting started with Docker. The internet is evolving day by day.
