- 1. Introduction to Docker UNDERSTANDING CONTAINERIZATION TECHNOLOGY NAME – GAURAV NAINWAL DATE- 18/09/2024
- 2. What is Docker? Docker is an open-source containerization platform for developing, shipping, and running applications. "It helps developers put their apps into containers." Containers allow for consistent environments across different stages of development.
- 3. Traditional Deployment vs Docker Deployment
- 4. Docker vs vm
- 5. Virtual Machines vs. Docker Containers
- 6. Key components of Docker Docker Engine: It is a core part of docker, that handles the creation and management of containers. 1.Server 2. Rest Api 3. Client Docker Image: it is a read-only template that is used for creating containers, containing the application code and dependencies. Docker Hub: It is a cloud based repository that is used for finding and sharing the container images. Docker file: It is a script that containing instruction to build a docker image. Docker registry: It is a storage distribution system for docker images, where we can store the images in both public and private models.
- 7. How Docker Works Docker uses Images, which are lightweight, standalone, and executable software packages. Containers are instances of images that run isolated processes.
- 8. Docker Architecture Docker Engine: Core part of Docker engine, composed of Docker Daemon and CLI. Docker Daemon: Manages Docker objects like images, containers, and networks. Docker CLI: Command-line interface to interact with Docker. Docker Registry: All the docker images are stored in the docker registry. There is a public registry known as a Hub. That can be used by anyone. We can run our private registry also.
- 10. Popular Docker Commands •docker build: Create an image from a Dockerfile. •docker run: Start a container from an image. •docker ps: List running containers. •docker stop: Stop a running container.
- 11. Advantages of Docker Docker uses less memory. Containers run faster than the other Virtual Machines. It is lightweight. It allows us to use a remote repository to share your containers with other teams. To reduce the risks, it uses dependencies.
- 12. Disadvantage of Docker Complexity will increase due to layering. It is difficult to manage a large number of containers. For an application that needs better graphics, Docker is not suitable for it. (limited access of gpu support)
- 13. Conclusion •Docker revolutionizes app deployment with portability, efficiency, and consistency. •Plays a crucial role in modern development, especially for cloud-native applications. •Key takeaway: Start using Docker to streamline your development and deployment processes.
