Docker containers provide immutable infrastructure for application packaging and deployment. Containerization improves agility, scalability, and efficient utilization of resources.
A container virtualizes the underlying OS and causes the containerized app to perceive that it has the OS—including CPU, memory, file storage, and network connections—all to itself. Because the differences in underlying OS and infrastructure are abstracted, as long as the base image is consist...
Today, Docker containerization also works with Microsoft Windows Server and Apple MacOS. Developers can run Docker containers on any operating system. All of the leading cloud service providers (CSPs), including Amazon Web Services (AWS), Microsoft Azure, Google Cloud Services and IBM Cloud®, ...
Docker images stored in its repository. It manages the distribution of images and also can integrate with application development workflows. Developers can setup their own Docker Registry, or use a hosted Docker Registry service such as Docker Hub, Oracle Container Registry, Azure Container Registry,...
A Docker host is any system with a running Docker instance. Hosts interact with the Docker daemon to create and manage containers. While the Docker host is commonly a single, independent machine, container orchestrators such asDocker Swarm and Kubernetescan distribute the role of a single host ac...
While Docker Hub is a popular option, there are many other available container registries available today, including Amazon Elastic Container Registry(ECR), Azure Container Registry (ACR), and Google Container Registry (GCR). You can even run your private registry on your local system or inside ...
Containerization is the packaging of software code to create a single lightweight executable—called a container—that runs consistently on any infrastructure.
A Docker container is a running instance of a Docker image. However, unlike in traditional virtualization with a type 1 or type 2 hypervisor, a Docker container runs on the kernel of the host operating system. Within a Docker image there is no separate operating system, as illustrated in Fig...
