In the IT corporate world, Docker certifications are very sought-after. This certification is for businesses that use Docker Enterprise Edition (EE), in their business operations.
What is Docker?
Docker is designed to make it easier and faster to build and deploy new applications. Docker allows developers to use Docker containers to wrap software and use standard units to run, code and apply system tools to build new applications. The Docker container is compatible with Linux and Windows. Additionally, the Docker tools can be used to create highly responsive and useful web apps.
Relationships between DevOps and Docker
Docker supports the DevOps key principles. It allows for greater speed and agility in programming.
Developers can quickly replicate environments using containerization platforms like Docker. This allows DevOps teams to spend less time configuring the environment and move on to the next phase of programming.
Docker allows developers to write simple code and set up instructions. Docker does a lot of the heavy lifting. It’s a great tool for DevOps teams who need to be able to act quickly and with precision.
Top Docker DevOps Certifications

Final Thoughts
Docker is an integral part of software development today. Docker allows you to ship all dependencies of software, including libraries and services. This helps to decouple the dependency on infrastructure from your application environment. Docker is being used by almost every digital company today. Major tech companies use it extensively. They are always looking for employees who can make web applications that are user-friendly and highly beneficial to their customers. A Docker certification shows potential employers that you are knowledgeable about the platform.
Any number of certifications for DevOps can be included in Docker certifications. You can also learn about DevOps’ peripheral principles, which can be used in Docker. The range of Docker certifications is not limited to DevOps certifications.
These certifications usually include either online or in-person coursework followed by a test. As with many certifications, tests can be taken online and in person at testing centres. Many certification boards offer proctored online testing. You can check with them to learn more about their efforts to make online education and testing more accessible.
