Lightweight container technology is revolutionizing IT infrastructure environments, and Docker containers are the frontrunners in this new era of enterprise ready container platforms. With the easy portability that Docker affords, organizations have the freedom to build and manage applications and deploy them across multiple infrastructures. This greatly increases operational efficiency and developer productivity, allowing applications to be run seamlessly across one server or deployed across multiple servers.
Over 700 million Docker containers are in use today, with over 10000 companies adopting Docker technology. Docker currently represents 83% of all containers in use. Containers enable a developer to package up an application with all of the parts, dependencies and libraries it requires, and ship it out as one single package. In this way, the developer can be assured that the application will operate other Linux machines even when the customized settings on the machine differ from the one used to write and test the code on.

Creating a multi-container application using Docker
Docker is a containerization platform. It is an open-source platform to create, deploy and manage virtualized application containers on an operating system (OS). It does this with the help of some allied tools.
Docker is primarily used for developing and running applications.
Docker has a client-server architecture. At the first level, Docker Client is present which sends commands to Docker Daemon or Server. Docker Daemon receives commands from Docker Client either through CLI (Command Line Interface) or REST APIs. Docker Daemon is responsible for all actions related to Containers. Images are the basic building blocks, i.e. all containers are built from the images. Images are maintained and organized in a layered manner.
The earliest development of Docker dates to the year 2010 when it was founded by Solomon Hykes and Sebastien Pahl. It was launched in 2011. Docker was made open to the public in 2013 at the Santa Clara PyCon. It was around this time that the containerization concept saw an increase in popularity.
Docker first used LXC (LinuX Containers) and later replaced that with its own library – libcontainer. Gradually, Docker separated itself from the rest of the pack to create its own offering of a complete ecosystem for container management.
Docker is very popular because it has changed the software application delivery and deployment landscape. To begin with, Docker is very easy to learn and to use. It helps in the scaling of systems and faster and better delivery of software applications. Also, the rise of the Microservices architecture led to the popularity of Docker.
The major purpose of Docker is to deploy applications to the production environment as required by operations. Docker is a tool made to create, deploy, and run applications by using containers.
You can use Docker –
Docker is written in the Go programming language.
The cost of Docker depends on the edition you want to use.
Docker helps create, deploy, and manage applications in an efficient manner and thus helps both Developers and System administrators. By virtue of this, Docker becomes an essential DevOps tool.
Yes, Docker is a deployment tool. As a DevOps tool, Docker is used to automate the deployment of applications in lightweight containers.
Docker is not a build tool, but it does help decrease the complexity and increase the efficiency of a build environment, since it puts the entire build environment into a Docker container.
Docker can run on Linux, Windows, and Mac platforms.
The time needed for learning Docker will depend on your experience. Here is a 5-day plan that can help you learn the fundamental concepts of Docker and how to use it.
Day 1: The first day is for the introduction. Today, you have to focus on theoretical concepts like Why Docker is used, how Docker was created, the basic terminologies container, images, etc.
Day 2: The second day involves using some of the most essential commands of Docker. You will learn how to pull an Nginx Docker image, run an Nginx container, use the ‘detach’ mode to run a container, run commands inside a container, and commands for container management.
Day 3: This day is for going deeper into Docker and learning about Storage and Networks. This will include Storage in Docker, Using Nginx containers with bind mounts, Using Volumes with Mongo image, Networks in Docker, and Connecting two containers on the same network.
Day 4: Now is the time for Dockerfiles. You must learn what the Dockerfiles are used for, using Dockerfiles for dockerizing a static website, and Dockerizing a NodeJS Express application.
Day 5: The last day is for learning ‘Docker Compose’. This is a tool used for Docker local development. With Docker Compose, you can centralize the ‘build’, ‘run’, and ‘create volume’ in a file named docker-compose.yml. You have to also learn how to write a docker-compose file.
To get deeper, it is recommended that you go for a Docker course. There is still so much left to learn and training will help you get an understanding of everything.
Before you decide between learning Kubernetes or Docker, you must know that they are not direct competitors. Docker is a containerization platform. Kubernetes, on the other hand, is the container orchestrator for container platforms such as Docker.
Containers are an important aspect of application development as they can solve a critical issue. While writing codes, developers wear their own local development environment. The code might work perfectly in this environment but not when you move it to production. The reason for this can be different operating systems, libraries and dependencies. Containers separate the code from the underlying infrastructure. All that developers have to do is pack up the application with all the libraries and bins into a small container image. You can run this container on any computer with a containerization platform.
Docker is one of the most popular container platforms. It is an open standard for the packaging and distribution of containerized applications. But this leads to another problem. How can these containers be scheduled and coordinated? How can an application be upgraded without any interruption of service? The solution for these problems include programs like Kubernetes, Docker Swarm, and Mesos that provided an abstraction for making a cluster of machines act like one big machine. This is vital for a large-scale environment.
Kubernetes is a container orchestrator used for automating deployment, scaling, and scheduling containerized applications. It supports several containerization tools like Docker. Currently, it is the market leader in orchestrating containers.
Docker is a tool and platform used to build, distribute, and run Docker containers. Kubernetes is a container orchestration system that can be used for Docker containers. It is more extensive than Docker Swarm and can coordinate node clusters at scale in production. You can run a Docker build on the Kubernetes cluster. However, Kubernetes is not a complete solution in itself and you have to include custom plugins.
You can use Docker without Kubernetes, In fact, this is common practice as even though Kubernetes has several advantages, it is extremely complex. You need a container runtime for orchestrating the container. So, you will need to use Kubernetes with a container platform like Docker.
Here is what you should learn before starting Docker:
Here is why you should learn Docker:
All developers must learn Docker. This is because, a few years from now, recruiters hiring for software developers will automatically filter out those who have not worked with any DevOps orchestration tools.
Ever since DevOps orchestration tools were released, a lot of tasks, mainly from the Ops side, have been cut short. Also, Docker is an important deployment tool as well. There are two categories in Deployment:
The best benefit offered by Docker is that it keeps the development, building, and production environment consistent. This means that there will be no sudden bugs or failures. This is why it is important that developers know how to use Docker.
Docker uses the Linux OS and hence cannot be run on Windows directly. So, you will have to install a virtual machine (VM) running Linux. The Docker images will run on the VM but can be controlled by Windows. All this is made possible by the Docker Toolbox.
The Whale (from Docker Logo) in the taskbar indicates the running Docker instance.
Open a Windows terminal (Command prompt) or PowerShell and type – docker run hello-world
You should get a message – “Hello from Docker …”. This verifies that Docker has been installed successfully.
Yes, you can run Docker on Windows and this requires the installation of the Docker Toolbox on Windows. You can then run Docker on Windows successfully.
The main benefits of using Docker are–
Docker is used to offset the various disadvantages that Virtualization brings. By using Docker, developer teams can create applications with multiple features. They can upgrade, test, and deploy them in a much faster and efficient manner leading to a shorter release cycle and faster time-to-market.
Some major use cases of Docker are–
Docker is used for Continuous deployment of multiple applications in the production environment during the DevOps cycle or process.
There are over 12,000 companies all over the world that use Docker technology. Majority of these companies are American and from the IT sector. JPMorgan Chase, ThoughtWorks, Inc., Docker, Inc., Neudesic, and SLALOM, LLC are the top 5 companies that use the Docker tool.
Yes, it is safe to use Docker in production environment. But the important thing to keep in mind is that as a user you should implement all the safety measures in place. From applying updates to running CI tests to monitoring containers periodically and running the latest versions – the safety measures must be adhered to.
Docker is an important technology to master from the perspective of a DevOps professional. As a developer, you will need to learn Docker to build/develop applications. As a testing professional, Docker will make it easier for you to test and deploy applications. Hence, Docker is a useful tool to learn as it’s an integral part of the DevOps process.
Ideally, there are no specific prerequisites to learn Docker, but it is good to have some basic understanding of Command LineInterface and Text Editor.
Then, move some resources on Docker from docker official website.Then, it is recommended to take some online or in-person training from good certified training institutes.
Regular practice and application of learning through live projects and use cases should help you gain a better grasp of Docker.
Some good resources are –
Luckily, to learn Docker all you need is a basic understanding of Command Line Interface and Text Editor. Also, an idea on Linux Administration and Networking is important.
Some understanding on the concepts such as – Virtualization, Virtual Machines, Containers will greatly help you understand the important role Docker plays in the web application development, management and deployment.
Developers can gain more by learning Docker.
To begin with, Docker is a relatively easier technology to learn and implement. The other advantages are –
From a career perspective –
Docker is not difficult to learn. Having said that, the learning curve depends a lot on your enthusiasm/intent and your understanding of basic concepts.
If you are already a developer, learning the basics of Docker shouldn’t be that difficult and you can go on to learn about building Docker images and building Code inside the containers.
If you are not a developer but a fresher, no worries. It’d be good to begin with understanding the basics of– DevOps, Virtualization, Virtual Machines, Containerization – and how all of these play a great role in the development of web applications.
