Docker is an open platform for developing, shipping, and running applications.Docker enables you to separate your applications from your infrastructure soyou can deliver software quickly. With Docker, you can manage your infrastructurein the same ways you manage your applications. By taking advantage of Docker’smethodologies for shipping, testing, and deploying code quickly, you cansignificantly reduce the delay between writing code and running it in production.
We believe simplicity is relevant to all sizes of environments, so we design for busy users of all types: developers, sysadmins, release engineers, IT managers, and everyone in between. Ansible is appropriate for managing all environments, from small setups with a handful of instances to enterprise environments with many thousands of instances.Learn more
Docker provides the ability to package and run an application i a loosely isolated
environment called a container. The isolation and security allows you to run many
containers simultaneously on a given host. Containers are lightweight and contain
everything needed to run the application, so you do not need to rely on what is
currently installed on the host. You can easily share containers while you work,
and be sure that everyone you share with gets the same container that works in the
Docker provides tooling and a platform to manage the lifecycle of your containers:
Develop your application and its supporting components using containers.
The container becomes the unit for distributing and testing your application.
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.
