Often, an image is based on another image, with some additionalĬustomization. This section is a brief overview of someĪn image is a read-only template with instructions for creating a DockerĬontainer. When you use Docker, you are creating and using images, containers, networks, When you use the docker push command, Docker pushes When you use the docker pull or docker run commands, Docker pulls the required images from your configured registry. You can even run your own private registry. Registry that anyone can use, and Docker looks for images onĭocker Hub by default. Docker registriesĪ Docker registry stores Docker images. For more information, see Docker Desktop. Docker Desktop includes the Docker daemon ( dockerd), the Docker client ( docker), Docker Compose, Docker Content Trust, Kubernetes, and Credential Helper. Docker Desktopĭocker Desktop is an easy-to-install application for your Mac, Windows or Linux environment that enables you to build and share containerized applications and microservices. The Docker client can communicate with more than one daemon. When you use commands such as docker run, the client sends theseĬommands to dockerd, which carries them out. The Docker client ( docker) is the primary way that many Docker users interact A daemon can alsoĬommunicate with other daemons to manage Docker services. Objects such as images, containers, networks, and volumes. The Docker daemon ( dockerd) listens for Docker API requests and manages Docker That lets you work with applications consisting of a set of containers. The Docker client and daemon communicate using a REST API, over UNIX Run on the same system, or you can connect a Docker client to a remote Dockerĭaemon. The Docker client talks to theĭocker daemon, which does the heavy lifting of building, running, andĭistributing your Docker containers. Docker is perfect for high densityĮnvironments and for small and medium deployments where you need to do more withĭocker uses a client-server architecture. To hypervisor-based virtual machines, so you can use more of your serverĬapacity to achieve your business goals. It provides a viable, cost-effective alternative

Running more workloads on the same hardwareĭocker is lightweight and fast. Manage workloads, scaling up or tearing down applications and services asīusiness needs dictate, in near real time. Machines in a data center, on cloud providers, or in a mixture of environments.ĭocker's portability and lightweight nature also make it easy to dynamically DockerĬontainers can run on a developer's local laptop, on physical or virtual Pushing the updated image to the production environment.ĭocker's container-based platform allows for highly portable workloads. When testing is complete, getting the fix to the customer is as simple as.When developers find bugs, they can fix them in the development environmentĪnd redeploy them to the test environment for testing and validation.They use Docker to push their applications into a test environment and run.Your developers write code locally and share their work with their colleagues.Containers are great for continuous integration and continuous

Standardized environments using local containers which provide your applicationsĪnd services. What can I use Docker for? Fast, consistent delivery of your applicationsĭocker streamlines the development lifecycle by allowing developers to work in Production environment is a local data center, a cloud provider, or a hybrid When you're ready, deploy your application into your production environment,Īs a container or an orchestrated service.The container becomes the unit for distributing and testing your application.Develop your application and its supporting components using containers.

You can share containers while you work,Īnd be sure that everyone you share with gets the same container that works in theĭocker provides tooling and a platform to manage the lifecycle of your containers: Containers are lightweight and containĮverything needed to run the application, so you don't need to rely on what's The isolation and security lets you to run manyĬontainers simultaneously on a given host. The Docker platformĭocker provides the ability to package and run an application in a loosely isolatedĮnvironment called a container. Significantly reduce the delay between writing code and running it in production. Methodologies for shipping, testing, and deploying code, you can In the same ways you manage your applications. With Docker, you can manage your infrastructure

Best practices for Dockerfile instructionsĭocker is an open platform for developing, shipping, and running applications.ĭocker enables you to separate your applications from your infrastructure so.
