- Getting Started With Docker
Docker is the leading software containers platform. Founded in 2013 as Linus developer tool, fundamentally solves the “works on my machine” problem. Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.
Docker provides the ability to package and run an application in a loosely isolated environment called a container. The isolation and security allow you to run multiple containers simultaneously on a given host. Containers are lightweight because they don’t need the extra load of a hypervisor, but run directly within the host machine’s kernel. You can even run Docker containers within host machines that are actually virtual machines!
Docker provides tooling and a platform to manage the life cycle of your containers. It Docker provides tooling and a platform to manage the life cycle of your containers. It simplify application deployment. When you’re ready, deploy your application into your production environment, as a container or an orchestrated service. This works the same whether your production environment is a local data center, a cloud provider, or a hybrid of the two.
Docker Engine is a client-server application with these major components:
- A server which is a type of long-running program called a daemon process (the dockerd command).
- A REST API which specifies interfaces that programs can use to talk to the daemon and instruct it what to do.
- A command line interface (CLI) client (the docker command).
