The Docker platform can be used to develop, publish and run applications, and is an open platform. Docker enables the separation of applications and infrastructure and the rapid delivery of software. With Docker, users can manage the infrastructure as they would an application, and the way Docker publishes, tests, and deployable code greatly reduces the latency between writing code and running it in production.

Docker supports packaging and running applications in loosely isolated environments called containers. With isolation and security, multiple containers can be run simultaneously on the server. Containers are lightweight and contain everything you need to run your application. Docker provides tools and platforms to manage the lifecycle of containers. What are Docker's uses for developers?

Docker provides native containers for applications and services that allow developers to work in a standard environment, greatly simplifying the development lifecycle. Containers are ideal for continuous integration and continuous delivery workflows. For example, developers can write code locally and share their work with other colleagues through Docker containers. Use Docker to push applications to test environments and test them both automatically and manually. When Docker finds errors, it can fix them in the development environment and redeploy them to the test environment for testing and validation. Once the test is complete, sending the fix to the customer is as easy as pushing the updated content into production.

Docker is a container platform that provides highly portable workloads, and Docker containers can be used on a developer's local laptop, physical or virtual machine in a data center, cloud service provider, or hybrid environment. Docker's portable lines and lightweight features make it possible to dynamically and easily manage workloads, scaling or dismantling applications or services in near real time based on business needs. Therefore, it can be said that Docker is extremely responsive and scalable.

Lightweight and fast, Docker provides a cost-effective solution for hypervisor-based virtual machines that can support running more workloads on the same hardware. Docker is ideal for high-density environments and small to medium deployments that need to do more with fewer resources.

Docker uses a client-server architecture, where the client is responsible for sending commands and the server (Docker daemon) is responsible for executing those commands, such as building, running, and distributing containers. The two can communicate on the same system through REST apis or over the network. Docker clients can also be Docker Compose, which is used to manage multi-container applications. Users typically interact with docker through the Docker command line tool, which passes commands to the dockerd daemon for execution. The client can control multiple daemons.
