Docker software is one of the most bleeding-edge technologies in the world. It has become the core of software development. It is one of the most captivating technologies that is being used by various developers for system architecture and software development. Docker’s software approach helps developers work without dependencies. Docker allows developers to focus on the important aspects of developing the software without worrying about the environment in which the application is going to run. If you are a beginner and want to understand what a Docker is before joining a Docker course, then read on. It will also help developers in Java and C++ to advance their careers and become DevOps engineers.

Importance of DevOps Tools

The term DevOps is short for ‘Development + Operation’. DevOps is a set of processes that help in bringing various operations teams together for completing software development. Traditional approaches to software development are slower than DevOps because it allows to create and improve products at a faster pace. It helps in production by increasing cooperation and efficient communication between the IT operations team and the development team. This helps in the smooth functioning of all the stages of product creation. Many DevOps practices are involved in the procedure to achieve this milestone, such as continuous integration (CI), continuous deployment, microservices, continuous delivery (CD), process automation, configuration management, etc.

There are many reasons the industry is rapidly adopting DevOps tools. And, some of them are:

• Faster innovation and shorter development cycles

DevOps helps combine the development and operations teams which helps to make applications ready for use in a shorter amount of time. This is a very important reason for the use of DevOps because companies usually succeed in their business on their ability to cater to customer needs faster than rival companies.

• Reduced failures in deployment and reasonable time to recover

Programming failures can cause many issues in deployment. DevOps supports the frequent release of codes because of its shorter development cycle which makes it easy for developers to spot code defects faster. This reduces the number of deployment failures and also gives reasonable time to recover from defects because development and operations teams will be working together on a problem.

• Improved communication

The communications team and the operations team work together on deployment and problems which results in better collaboration between the groups. This improves the performance of the company and gives rise to a better customer experience and support. When the teams trust each other, experiments and innovations are run more effectively leading to an overall improvement.

• Increase efficiency

Increased efficiency can lead to a faster development process that is less prone to errors. DevOps tools can be automated for continuous integration which reduces the amount of manual work significantly. This makes it easier for engineers as they can then completely focus on the work and processes that cannot be automated.

• Reduced costs

Using DevOps tools can reduce the IT headcount and lead to reduced overall costs.

What is Docker?

To understand what Docker is, let’s take an example. Imagine the shipping industry and its transport system. Earlier, there used to be no containers and all the goods had to be loaded individually into the vehicle for transportation purposes. Then gradually, we came to the idea of containers and then, the same products were loaded in them, which made the work easier and less time-consuming. Eventually, the more convenient idea of different-sized containers came into being, for different-sized products. 

Think of Dockers as working on the same concept of these containers, but instead of carrying goods, they are taking different pieces of software. Notably, software is not a monolithic piece but carries several technologies with it like its part. Some of these parts include shell scripts, databases, application servers, web servers, and configuration files. It is not easy to set up a complex application because you need various things to complete the application. Docker solves this problem by putting everything needed into a container and then deploying it to Mac, Linux, or Windows, wherever you need it.

This helps in simplifying the processes and steps of software development and makes it easy for DevOps professionals. Therefore, if you want a good career in DevOps and want to increase your productivity on the job, then a good knowledge of Dockers is essential.

How to Start a Career in Docker?

If you want a career in Docker, then you need to have a good knowledge of the Docker software which can only be gained through a detailed and structured course. You will need a course that teaches about containerization from scratch and helps you understand the benefits of the development and deployment of applications in containers and how Dockers can help you achieve that. Automation of software development should also be covered in the course as it is an important step. Some of the courses that will help you achieve these goals are:

• Learning Docker

In this course, you will learn:

• The basics of Dockers, containers, and Docker files, including data management, infrastructure optimization, and networking
• How to build, network, and link containers?

• Docker Mastery: Kubernetes+Swarm from a Docker Captain

This course is extensive and covers a wide array of topics. In this course, some of the things you will learn include:

• Creating your own image registry
• Creating a three-node Swarm cluster
• Optimizing Docker files for faster development and deployment
• Uploading container updates, etc.

• Projects in Docker

This is a complete course that covers topics from basics to mastery in Dockers. In this course, you will learn:

• Docker core concepts and basics
• Building Docker containers on a single host
• Creating a Docker container swarm, etc.

There are many courses available online that you can choose from, but these are some of the best for beginners in Docker.

The industry is implementing DevOps and Docker at a faster pace than ever imagined. In this scenario, if you want a career that is rewarding and rapidly growing, then you should consider taking a Docker course. Organizations have become eager now more than ever to take advantage of this enhanced innovation with a more stable operating environment, performance-focused teams, and faster delivery of applications. You can easily take up a Docker course online and start working as a Docker professional to be part of an exciting and rewarding career.
