20 Useful Docker Commands

Hey there! I am Palak. I like writing technical blogs and sharing my knowledge with the community. I am passionate about Cloud & DevOps. I am writing this blog to share the Docker commands that I mostly use.

Docker was released as an open-source project in 2013. Docker enables developers to easily pack, ship, and run any application as a lightweight, portable, self-sufficient container, which can run anywhere. Docker is an application that simplifies the process of managing application processes in containers.

Containers let you run your applications in resource-isolated processes. Theyre similar to virtual machines, but containers are more portable, more resource-friendly, and more dependent on the host operating system.

So, let's get started.
