Docker is a technology or platform that makes it easier to create, deploy, package, and ship programmes, as well as its components like libraries and other dependencies. Its main goal is to automate the application deployment process and virtualization at the operating system level on Linux. It enables several containers to run on the same hardware, resulting in increased productivity, as well as the isolation of programmes and the ease of configuration.
The benefits and use cases of containerizing programmes that allow development and rapid release are why Docker is so beneficial for DevOps. DevOps is generally used to handle 'Dev' and 'Ops' issues, and Docker appears to solve the majority of them, the most important of which is that it can run on any system. As a result, all teams are able to interact and operate more effectively and efficiently.
