What are Docker jobs?Docker is a tool that enables developers to create, deploy, and run applications in a container. A container is a self-contained unit that includes everything the application needs to run, including the code, libraries, tools, and configuration files. Docker is popular in the startup world because it allows developers to create and run applications quickly and easily, without having to worry about setting up a complex infrastructure. Docker jobs typically require experience with containerization, Linux, and DevOps. Common job titles include Docker Engineer, DevOps Engineer, and Linux Systems Administrator.
