The importance of containers and container-based applications is evident in the current world. Just a simple look into what has happened in this space, even a year ago, would tell us exactly how significant these applications are. DevOps like Docker was a rare skill for any recruiter to find in its potential employee. Now, it sits comfortably in the first position in terms of what most recruiters want in their employees and that too, regardless of the size and the nature of the organization.
This phenomenal rise of Docker has created a need for a Docker certification. The reason is very simple; there is no better way to learn and master Docker than by entering and skilling up through a Docker certified associate course. We will get into why you should be looking into an online Docker course, but before that, let us understand the rise of DevOps.
Increasing adoption of DevOps:
DevOps is an umbrella term for some of the techniques and practices that have taken the entire tech community by storm. The tools and techniques which DevOps encompasses are not all brand new. However, when combined, they can lead to some favorable results.
DevOps was born from two prevalent trends in the entire tech community. You can easily distinguish the two very different sets of directions if you are to study DevOps from within the two trends – “agile infrastructure” and “the need for the operations and development team to communicate”.
This is the reason why DevOps is becoming increasingly popular. According to a study conducted in the Information and Technology sector of the United States of America, it has been found that the entire market of DevOps is supposed to grow about 12.85 Billion United States Dollars (USD).
We can also see this rising trend of DevOps from the adoption statistics. According to Statista, the adoption of DevOps has seen an increase of about 17% in the year of 2018 itself. The reason for this adoption could also be inferred from the statistics. It was seen that the teams which used DevOps have seen about a 63% improvement in the quality of software that was deployed. DevOps provide us with such advancements in the quality of life as a programmer (like the ability to make quick amends, allow for a smooth collab between the teams, reduction in clutter and thus increased focus on just the project at hand, etc.) that makes it an indispensable tool in the whole tech circle.
What is Docker?
Docker is a platform used to build applications that use something known as containers. To understand Docker is to master containers.
Containers are just a unit (standard but could depend on the service and the application) of an application or even a software. It is called a container because one container is bundled with all the code and the dependencies required, ensuring that the code runs smoothly. One immediate benefit of using containers is the reliability that the application would run similarly regardless of the system.
Since Docker is built keeping containers central to its operations, you could see the same when using it. You can use these containers to pack your software and get all the useful code that would be needed to run your software at a single place.
Docker is an open-source project that came to the limelight in 2013. It is single-handedly responsible for bringing containers to the mainstream.
Top Docker skills that employers look for:
There are many skills which the recruiters look for when choosing an employee to handle Docker-based applications in their organization. Since Dockers can be integrated with almost any language and application, a recruiter might look out for a wide variety of skills in its new employee. One thing to note before we discuss what skills are highly sought after, you should first look for the company and its job posting. It might be the case that you would have to gain a new Docker skill.
So, below is a list of some of the top skills which recruiters look out for:
- Docker with Kubernetes and Swarm
- Docker for web developers (using images with Docker files, communication between the containers, etc.)
- Both Up- and Down-scaling of any Docker-based application
- Integrate various DevOps with Docker
- Docker with Node.js (for handling the backend of any server)
Why take a course and get Docker certified?
Since Docker’s whole technology is relatively new, chances of getting any formal degree or education that teaches you the ins and outs of Docker are going to be very difficult. Even if you do manage to find a chance, you might not like the pace or material taught. Any factor can ultimately stop you from learning Docker since it is new, and properly structured degree courses are rare to find.
To eradicate all the problems associated with any degree or a Bootcamp, you can take a different approach. You can choose to join a certificate course online. The merits of choosing your certification course are many. Not only will you be able to dictate the pace at which you learn the stuff taught, but you will also get a considerable degree of freedom in choosing your instructor and the course contents.
Not just that, you will be awarded a certificate of completion, which you can use in your resume to formally show that you have put money where your mouth is. You will also get access to the broad community associated with that course, be it community page, Question and Answers page, discord server, or even subreddits. These communities across multiple platforms would be filled with like-minded people who could provide you with any assistance you might need. Some organizations could also help you land a job as well.
The use of containers and Docker is at an all-time high. According to pundits, it is only said to grow further as time progresses because we are moving into the age where cloud computing will inevitably dominate the entire computing world. There are many benefits which are associated with using Docker as well. Now, you just need to choose your course and become future-ready by mastering the Docker ways.
