Kubernetes is one of the leading container orchestration platforms. Companies prefer Kubernetes for their projects because of its cloud-agnostic approach that efficiently manages workload whether your project resides in the cloud or on-premises. It has freed companies from being locked into the services offered by their cloud provider or managing entire team operations on-premises or virtualization platforms. This is why Kubernetes is one of the most critical technologies in the DevOps domain. In 2021, there were over 3.9 million Kubernetes developers worldwide, which is a 67% increase from the previous year. As the adoption of technology increases, it is a valuable skill to add to your resume.
This Kubernetes developer toolkit lists the best resources to learn, upskill, and succeed in the industry.
Microservices: Kubernetes developers must know how to develop software applications based on microservices. Even when the programming languages are the same, developing applications for Kubernetes based on modern architecture requires different coding patterns and software release processes.
System administration: Releasing software updates regularly on a Kubernetes hosting platform requires advanced system administration skills. With the traditional approach of deploying code, there is no way to know the scalability flaws unless the software is installed and used by the customers. But the modern software architecture requires developers to learn Linux commands and database queries to test the software in production.
CI/CD: Kubernetes is for hosted applications with continuous integration and continuous delivery (CI/CD) as an integral part. As a Kubernetes developer, you must be familiar with CI/CD tools like Jenkins. You need to know how coding and software deployment steps can be automated. You will be asked about concepts like unit and functional tests, deployment of the Kubernetes pods, and code compilation in a hosted environment.
API support: You need to be able to create an Application Programming Interface (API) for the software deployed on Kubernetes such that users who want to interact with your hosted application directly can do it. You must know the concepts of API, such as JSON or YAML files. Learn more about tips on creating robust APIs.

As essential as technical skills are for Kubernetes developers, they also need soft skills to be part of the DevOps teams.
Communicate clearly: DevOps environment requires transparent communication. You must develop communication skills to share ideas and ask questions comfortably when needed. You must always be clear about the intentions in your conversions, such that there is no scope for misinterpretation or ambiguity.
Foster creativity: DevOps engineers need to think outside the box to push the limits and further the project’s potential. You are free to experiment with different approaches and tools to solve the given problem as long as you are within the DevOps guardrails.
Be willing to learn: A learner’s attitude is mandatory to progress in your DevOps career. You have to take the initiative and be willing to take on challenges you are not ready to accept. Active learning on the job sets you apart from the rest of the developers. We have listed dozens of learning resources above; use them to improve your skills continuously.
