Since a container consists of all the needed libraries and dependencies for a particular application, developers can easily pack, transfer, and run new app instances anywhere they like.Īdditionally, Docker and other virtualization solutions are crucial in DevOps, allowing developers to test out and deploy code faster and more efficiently.
DOCKER NETWORK KUBERNETES PORTABLE
What is Docker Used Forĭocker is used as a practical tool for packaging applications into lightweight, portable units (containers). For more information about these two components, check out Docker Image vs. Note: Images and containers are closely related so some users may find it difficult to understand their individual roles. The source code, dependencies, libraries, tools, and other files required for the application to run are packages into the image.
DOCKER NETWORK KUBERNETES HOW TO
The file outlines how to create a Docker image and automatically executes the outlined commands.Īll Docker containers are created from Docker images representing templates of an application at a specific point in time. The process begins with a script of instructions, called a Dockerfile. You can set up and use a private registry or use Docker Hub, a public registry from which Docker pulls images by default.
Therefore, one server can host multiple containers, each running a different app.Īlthough containers are similar to virtual machines, they differ by an additional virtualization layer since they utilize the kernel and operating system of the host. As they virtualize resources of the underlying hardware, they are lightweight, flexible, and cost-effective.
DOCKER NETWORK KUBERNETES SOFTWARE
It has revolutionized and removed many tedious processes of software development and remains the leading container platform today.Ĭontainers provide an isolated environment for packaging apps. What is Docker?ĭocker is an open-source containerization platform used for creating, deploying, and managing applications in lightweight packages called containers. This will help you understand why there is no clear comparison between the two. Read on to learn more about Docker and Kubernetes, their architecture, and what they are used. Learn more about how they differ in Kubernetes vs.
Note: Based on the role they play, you can compare Kubernetes to Docker's official container orchestration tool - Docker Swarm.
