Along with that, Docker offers multiple certifications programs including Docker Certified Associate (DCA) exam to validate the skillset with the real-world questions that are designed by experienced professionals. 

The main reason for choosing Docker for developing applications is that nowadays, applications require coding, frameworks, architectures, and multiple languages. Moreover, discontinuos interfaces between tools for each and every lifecycle stage creates tremendous complexity. Also, it simplifies and boosts your workflow, while giving developers the freedom to innovate with their choice of tools, application stacks, and deployment environments for each project.

Let’s start our Journey to understand in-depth information related to Docker Certification!

What is Docker Certification? What are the advantages of gaining Docker Certification?

Docker Certification is in increasing demand nowadays in the IT world. This certification authenticates that the candidate possesses all the technical knowledge, skills, and exposure with the industry-wide used and well-recognized credential of the docker platform. Here are some advantages of gaining Docker Certification that you should consider:

How to prepare for Docker certification?

Once you decide you want to appear in the exam, the first thing you need to do is practice hard. Or get the Docker certification tutorial and try to practice each section taught in the classes everyday. You can install Docker on any operating system: Mac OS, Windows, CentOS, Debian, Fedora, and Ubuntu, you will get to know about the below-mentioned points: 

  • Once you install Docker on your operating system then you can start with Image creation and management and practice each section again and again for better results.
  • Docker allows you to get 6 to 12 months of real-time experience. But, we personally feel that if you install Docker on your system and practice enough with all the sections required to pass the certification that will help you certify the exam efficiently.
  • Try to make a list of all necessary points from all the Docker exam sections as you practice. Making a handy list will help you go through the important things before you appear in the exam.
  • As  mentioned above, you have absolutely 90 minutes to complete 55 questions which make around 1 and a half minutes for each question. In case you are stuck or don’t know the answer for any question then you can just skip it to attempt it later. As it will help you in balancing time.
  • Mostly, being professionals we would recommend you to install the community edition. But installing Docker serves you with a free trial of enterprise edition for 30 days. Our professionals would recommend you using the trial since the exam equally focuses on some important topics like UCP, DTR etc.
  • Installing docker also allows you to read books as well on Docker. We would recommend starting with a few books including the Docker Deep Dive book by Nigel Poulton. Every book will provide you with a different perspective. Despite that, you can also go through the Docker Certification Training to prepare yourself for the exam.
  • If you are stuck or don’t find any solution to solve your problem in the Docker docs. Then, we would recommend you to search the web and read as many blogs as possible until the topic is clear to you.
  • Once you are familiar enough with the related topics, schedule an exam and start preparing for it. But unfortunately, if you don’t feel comfortable taking the exam then you can freely reschedule it for the next time as per your desire. Just Remember, there is no FREE retake for the Docker certification exam. You only get one chance.
  • Now, this exam includes some Kubernetes questions as well, which is why we would encourage you to understand how Kube and Docker works together.

Why must you own a Docker certification?

Just because an application works smoothly on your computer machine doesn’t necessarily mean it has to work on your friend’s computer too. But the Docker containers, the savior, help you run an application the same way on your friend’s system that it used to run on yours.

Here are some of the following reasons why you can’t say no to Docker Container:

  • It enables more efficient use of system resources
  • It allows instant software delivery cycles
  • It smoothes the application portability
  • It uses the tailor-made for microservices architecture

Who can apply for the certification?

Docker certification is available for everyone who wants to upskill and grow for living a better future! Moreover, your interest in cloud technologies and your aim to learn something out of the box is all you require as a prerequisite. Keeping the certification aside, having a good understanding of Docker Containerization technology will take you to better places for sure.
Here, we have listed a list a non-exhaustive (almost) list of professionals who should start their Docker Certified Associate journey for their betterment right now:

  • Software Developers
  • Cloud Professionals
  • Solutions Architect
  • Database Managers
  • Data Scientists
  • Testers
  • Release Engineers
