Docker is an open-source platform for shipping, developing and running applications. It allows you to differentiate your applications from your infrastructure so you can software quickly. Docker runs containers which include the software and other additional things that the software needs to run.
Docker containers swaddle a piece of software in an entire filesystem that contains everything needed to run: code, runtime, system tools, system libraries. This assures that the software will always run the same, anyhow of its environment
With Docker, you can easily organize your infrastructure in similar ways you can manage your applications. By captivating advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can remarkably diminish the delay between writing code and running it in production.
Docker utilizes client-server architecture. The Docker client interacts with the Docker daemon, which does the massive lifting of running, building and distributing your Docker containers. The Docker client and daemon converse using a REST API, over UNIX sockets or a network interface.
Why docker is required in .NET applications?
Compatible and rapid delivery of your applications
Docker smoothen the development lifecycle by permitting developers to work in systematize environments using local containers that provide your applications and services.
Containers are prominent for continuous integration and continuous delivery (CI/CD) workflows. .Net core Developers can write code locally and stake their work with their colleagues using Docker containers.
You can also use docker to push the applications into a test environment and run automated and manual tests. When developers search bugs, they can fix them in the development environment and redeploy them to the test environment for testing and validation.
Fix to the customer is as simple as pushing the updated image to the production environment when testing ends
Flexible scaling and deployment
Docker containers can execute on a developer’s local laptop, on physical or virtual systems in a data center, on cloud suppliers, or in a combination of environments. Docker’s container-based platform permits for highly portable workloads.
Docker’s flexibility and translucent nature also make it easy to vigorously manage workloads, escalating up or tearing down applications and services as business needs dictate, in near real-time.
Organizing more workloads on similar hardware
Docker is graceful and fast. It provides a feasible, cost-effective option to hypervisor-based virtual machines, so you can use more of your computer capacity to gain your business goals. Docker is ideal for high-density environments and for small and medium deployments where you need to do more with little resources and this is the reason that Docker is vastly used by many .Net development companies across the globe.
