- 1. LINUX CONTAINERS AND DOCKER OPEN PLATFORM Rahul More
- 3. Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications
- 4. ? • “an open source platform to pack, ship and run any application as a lightweight linux container.” • “chroot on steroids.”
- 7. WHY TO USE DOCKER- MINGLE • Developers • QA • Nebulous SYS Admins- ish
- 8. DEVELOPER S “works on my machine”
- 9. QA “does not work on my test environment”
- 10. SYS ADMIN “I want my weekend”
- 11. WHY USE DOCKER? • Portable deployments. • Fast Application delivery. • Scale and deployed with ease. • Higher workloads - greater density.
- 12. Dev App Container Tester Container Sys Admin Automation ProductionEnvironments
- 15. DOCKER • Client Server Architecture. • Socket or REST APIs • Docker Daemon • All container operations • Docker Client • Main interface between user and docker daemon. • Docker Internal Components.
- 16. DOCKER COMPONENTS • Docker Internal Components • Docker Image • Similar to OS disk images. • Used as base , layers build upon the base image[Layer 0]. • Portable. • Docker Registry • Repository of Docker Images. • Public or Private. • Docker Containers • Running Images • Directory + Execution Environment. • Isolated. • User Space + Networking + Security Components. Docker Image Kernal Docker Engine Docker Registr y Docker Container
- 17. WORKING OF DOCKER • Docker Image. • Each image is association of images. • Layered approach for abstraction. • Unified file system. Each layer as a directory. • Dockerfile. Base Image Layered Image-2[add apache] Running Container [php application Layered Image-2[add php] Layered Image-3[add mysql] Reference Image
- 18. WORKING OF DOCKER • Docker Registry. • All images are stored in a client. • Private or public. • Images are pulled and pushed in a registry.
- 19. WORKING OF DOCKER • Docker Container. • Run time environment. • Command from REST API/Docker Binary to run the container. • sudo docker run -i -t ubuntu /bin/ bash Docker client Docker Daemon Container Pulled Image REPOSITORY Creates Containers from Image Binary API Request
- 20. DOCKER • sudo docker run -i -t ubuntu /bin/ bash • Docker client will be launched with “docker run” command. • It tells the daemon, from which image the container should be created. In our example, it is a Ubuntu image. • “-i” tells the Docker daemon to run the container in interactive mode. • “-t” represents tty mode for interactive session. • “/ bin/ bash” tells the Docker daemon to start the bash shell when the container is launched. Docker client Docker Daemon Container Pulled Image REPOSITORY Creates Containers from Image Binary API Request
- 21. DOCKER • Successful Execution of run. • Checks for the image. • Pulls the image to create a container. • Creates a read/write filesystem over the image. • Creates a network interface for the container to interact with host machine. • Checks for IP . Allocates IP. • Executes the command specified. • Logs. Docker client Docker Daemon Container Pulled Image REPOSITORY Creates Containers from Image Binary API Request
- 22. IMMUTABLE INFRASTRUCURE • Immutable infrastructure comprises of immutable components and for every deployment the components will be replaced with the updated component rather than being updated.
- 23. DEMO • A static web application running on apache. • A mysql Image. • Wordpress application with MYSQL db. • Hosting multiple websites on docker host. • Building and testing containers using Jenkins CI.
