Top Docker Commands – You Need to Know

docker commands

Watching the demand for Cloud Computing, Docker is in high demand too. Learners want to learn Docker online. There are various options available to learn Docker online. Docker training mainly involves learning Docker Commands. There are more than 50 Docker commands.

This blog comprises a few common Docker commands, their use, architecture, and all about Docker training.

What is Docker?

Docker is a medium that allows building, deploying, and handling applications with the support of containers. A container makes an application runnable by packaging the code and all its reliances together. The container separates the application and its dependencies into a self-contained unit that can drive anywhere. Container withdraws the need for physical hardware that permits for more efficient computing resources use. Containers deliver operating-system-level virtualization. Moreover, developers can cooperate quickly without bothering regarding the software dependency they need to install.

A container is a running illustration of an image. An image is a read-only template with instructions for building a Docker container. You can make, begin, control, move, or delete a container with the Docker API or CLI. One can attach a single container to one or more networks and also attach storage to it. By checking the current state of the container, we can create a new image too!

What are the Docker Commands?

Here is a list of some Docker Commands:

  1. Docker Attach: Attach local standard input, output, and error streams to a running container.
  2. Docker Build: Build an image from a Dockerfile

What are the benefits of the Docker Commands?

Here are the reasons why a Developer must learn Docker Commands:

  • Docker facilitates how you devise and deploy your code, and handle your application.
  •  Importing your application into a container makes deployment and mounting smooth and drives automation. 
  • It makes DevOps effortless and makes your production environment rich.
  • With a more powerful push to Cloud every year, the container model will be the default model for software development, and Docker and Kubernetes will play a vital role shortly.
  • It adds an in-demand skill to their resume to get a better job.

What is the Docker use cases?

Let’s comprehend a few of the docker use cases: 

Use case 1: Developers write their code locally and share it using docker containers. 

Use case 2: Revising the bugs and employing them in the individual environments is as simple as pushing the image to the respective environment. 

Use case 3: Using docker one can propel their application to the test environment and perform computerised and manual tests.

Use case 4: One can make their deployment responsive and scalable by using docker since docker can manage dynamic workloads feasibility. 

What is the Docker Architecture?

The Docker Architecture generally consists of a Docker Engineer which is a client-server application with three major elements: 

  1. Generally, Docker pursues a client-server architecture. 
  2. The client conveys with the daemon, which takes up the task of installation, handling, and sending the docker containers. 
  3. The client and daemon convey using REST API calls. These calls work as an interface between the client and the daemon. 
  4. A command-line interface, Docker CLI executes docker commands.  
  5. The registry accumulates the docker images. 

What is a Docker Training?
