Today's apps have more functionality than ever, and the accelerating pace of the digital world requires developers to increase output to unprecedented levels. Docker is an innovative platform that lets developers efficiently test, build, and scale applications. It helps teams assemble their products by packaging all the needed components together. The result is a shorter product design journey, improved software management, and often a better product.

Organizations hire Docker developers for several reasons, including improved scalability and efficient application deployment. Businesses trying to capitalize on this type of development may discover hiring challenges due to the high demand for Docker developers. Hiring managers will need to know what skills they should possess, how much they make, and how to find the right candidate for maximum efficiency.

What Is Docker Development?

Docker is a platform that lets developers build, test, and run their products. It works by dividing your product's components into standardized packages containing all the necessary components to run on your operating system of choice. Docker development involves working with the Docker platform to manage each element of an application so that it functions as needed.

Why Docker Development?

Docker development is often a valuable part of a business’s growth. Businesses that utilize Docker’s deployment process can expect rapid development, which brings products to market faster. Further, Docker can help simplify and automate deployment and management aspects, allowing teams to focus on other areas of the business.

Docker development is cost-effective for your organization, too. It enables businesses to scale up or down based on demand, which limits the cost of resources to only what is needed. Because Docker uses lightweight containers instead of virtual machines, you'll spend less on hardware resources. Docker’s consistency across platforms minimizes development time and the troubleshooting of environment-specific issues, further decreasing costs.

Benefits of Docker Development

Docker is a popular choice for businesses and developers as it has multiple benefits. Some of the advantages of Docker development include:

• Compatibility: Docker works with multiple operating systems. It runs natively on Linux, but also works with Windows and macOS. While Docker doesn’t run on Android devices, developers still use it in the back-end Android development process.
• Portability: Because Docker containers run on any system that supports it, the underlying infrastructure isn’t constrained to specific rule sets. With this adaptability, developers easily move applications across cloud providers, servers, and local development environments.
• Efficiency: Docker’s resource utilization allows for cost-effective use of computing resources. Because Docker containers are more lightweight than virtual machines, they better utilize system resources by running on the same hardware instead of requiring their own operating system.

What Does a Docker Developer Do?

Docker developers must thoroughly understand how the platform works to make the most of its capabilities. They should be able to use it for any of the following tasks:

• Creating apps
• Coding
• Building continuous integration and delivery (CI/CD) pipelines
• Managing distributed microservices architectures
• Creating fully-managed platforms for developers

The purpose of Docker is to enable applications to run in any environment by furnishing each container with the artifacts it needs to perform. This means the fundamental job of a Docker developer is to leverage the platform to let the rest of the software function wherever it's needed.

Required Skills and Qualifications

On a technical level, Docker developers need to understand containerization, which is a lightweight form of virtualization, Docker commands, Docker Compose, and Dockerfile. Developers who are able to script in Bash or Python will be able to automate tasks, which facilitates faster development. Knowledge of Linux and Unix systems may also be beneficial, as Docker runs on Linux, but can run on other operating systems. Depending on the project, Docker developers may also benefit from an understanding of cloud services like Amazon Web Services (AWS) or the Google Cloud Platform (GCP), depending on their project’s requirements and goals.

Soft skills are equally important in enhancing a team’s productivity. Time management is a crucial skill that Docker developers need to master. Time management includes prioritizing and executing tasks, which facilitates rapid development. Developers with good time management skills will consistently meet deadlines and won’t create bottlenecks for other development team members.

Docker developers who are intrinsically motivated also provide a benefit to the team. Motivated developers will take it upon themselves to learn the newest technologies or familiarize themselves with beneficial libraries, frameworks, and programming tools. They are also likely to respond positively to constructive feedback and use it to better themselves.

It’s likely that most companies require a bachelor’s degree in Computer Science or a related field, though increasingly, practical experience is accepted in place of a formal education. Regardless, Docker developers at any level need a comprehensive portfolio that showcases an understanding commensurate with the position they are applying for.
