- 7. Docker Docker is an open platform for developing, shipping, and running applications quickly. It automates the deployment of applications into containers. “Build, Ship & Run Apps anywhere anytime…”
- 8. What is a Container? • Standardized packaging for software and dependencies • Isolate apps from each other • Share the same OS kernel • Works for all major Linux distributions • Containers native to Windows Server 2016
- 10. Comparing Containers and VMs Containers are an app level construct VMs are an infrastructure level construct to turn one machine into many servers Containers and virtual machines have similar resource isolation and allocation benefits, but function differently because containers virtualize the operating system instead of hardware, containers are more portable and efficient.
- 11. Containers and VMs together Containers and VMs together provide a tremendous amount of flexibility for IT to optimally deploy and manage apps.
- 12. Docker Components Let's look at the core components that compose Docker: ● The Docker client and server, also called the Docker Engine. ● Docker Images ● Registries ● Docker Containers
- 13. What is Docker Engine? Docker Engine is a client-server application with these major components: ● A server which is a type of long-running program called a daemon process. ● A REST API which specifies interfaces that programs can use to talk to the daemon and instruct it what to do. ● A command line interface (CLI) client.
- 14. Docker image ● A Docker image is a read-only template with instructions for creating a Docker container. ● You can build or update images from scratch or download and use images created by others. ● An image may be based on, or may extend, one or more other images. ● A docker image is described in text file called a Dockerfile, which has a simple, well-defined syntax.

- 16. Docker Registry A docker registry is a library of images. A registry can be public or private, and can be on the same server as the Docker daemon or Docker client, or on a totally separate server. Examples of public registries: https://hub.docker.com https://store.docker.com
- 17. Docker store • A marketplace for you to get the latest trusted containers, plugins, and Docker editions! • You can search, browse, purchase and manage from one location. • Community Edition for: −Mac −AWS −Fedora −CentOS
- 18. Docker Container A Docker container is a runnable instance of a Docker image. You can run, start, stop, move, or delete a container using Docker API or CLI commands.
- 19. How does Docker works? Docker uses a client-server architecture. The Docker client talks to the Docker daemon, which does the heavy lifting of building, running, and distributing your Docker containers. The Docker client and daemon communicate using a REST API, over UNIX sockets or a network interface. What happens when you run a container? $ docker run -i -t ubuntu /bin/bash When you use the docker run CLI command or the equivalent API, the Docker Engine client instructs the Docker daemon to run a container.
- 20. What can I use Docker for? Fast, consistent delivery of your applications... Docker can streamline the development lifecycle by allowing developers to work in standardized environments using local containers which provide your applications and services. You can also integrate Docker into your continuous integration and continuous deployment (CI/CD) workflow.
- 21. Containers use cases and success stories... Uber Accelerates Developer Onboarding from Weeks to Minutes with Docker “Docker provides a very good isolation of resources. We used to have a case where applications stepped on each other. This is annoying because all applications on the host if going to be affected. But Docker provides resource isolation , which helps us to prevent this scenario from happening.” Xiaojian Huang, Software Engineer, Uber
