- 4. 4 What is Docker? •Docker is a platform for developing, shipping and running applications using container virtualization from development to production both on premises and in the cloud. • Docker containers wrap up a piece of software in a complete file system that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server. • This guarantees that it will always run the same, regardless of the environment it is running in. https://www.docker.com/
- 5. 5 Why Docker? Docker createdthe industry standard for containers, so they could be portable anywhere. Docker provides a consistent environment for application from the development all the way to production Applications are safer in containers and Docker provides the strongest default isolation capabilities in the industry Containers share the machine’s OS system kernel and therefore do not require an OS per application, driving higher server efficiencies and reducing server and licensing costs

- 7. 7 Docker: Terms Docker Image Thebasis of a Docker container. Represents a full application. Docker Container The standard unit in which the application service resides and executes. Registry Service (Docker Hub or Docker Trusted Registry) Cloud or server based storage and distribution service for your images. Docker Engine Creates, ships and runs Docker containers deployable on a physical or virtual, host locally, in a datacenter or cloud service provider. Docker Volume The storage for persisting data generated by and used by Docker containers.

- 11. 11 Data Persistence inDocker: Dir Mapping • Use file system directories (mounting from host) during app development. easily to edit app in folder /myapp1 at development host easily to edit app in folder C:Usersuser10html at development host docker run --name mynginx10 –d -v /myapp1/html:/usr/share/nginx/html:ro -P nginx docker run --name mynginx20 –d –v c:/Users/user10/html:/usr/share/nginx/html –p 8080:80 nginx
- 12. 12 Data Persistence inDocker: Docker Volume • Use Docker volume for app development/deployment docker volume create evoting_db docker run –d –p 3306:3306 -v evoting_db:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=%P1lih4nR4y4#2023! mariadb:10.4-bionic Docker volume evoting_db mapping to MariaDB database folder Creating Docker volume named evoting_db

- 24. 24 Docker Hub akaApps Store • Docker Hub is the world’s largest repository of container images with an array of content sources including container community developers, open source projects and independent software vendors (ISV) building and distributing their code in containers. Users get access to free public repositories for storing and sharing images or can choose subscription plan for private repos. • Currently, there are 1,943,463 available images in the Docker Hub (January 27th 2019). https://hub.docker.com/
- 25. 25 Docker Hub –https://hub.docker.com
- 26. 26 Dockerfile • Docker buildsimages automatically by reading the instructions from a Dockerfile • Dockerfile: a text file that contains all commands, in order, needed to build a given image. • A Dockerfile adheres to a specific format and set of instructions. https://docs.docker.com/develop/develop-images/dockerfile_best-practices/ https://docs.docker.com/engine/reference/builder/ FROM php:7.2-apache COPY src/ /var/www/html/ Dockerfile docker build –t osdec/app1:1.0 .

- 27. 27 Docker Compose • Composeis a tool for defining and running multi-container Docker applications. • With Compose, you use a YAML file to configure your application’s services. • Then, with a single command, you create and start all the services from your configuration. • Put your recipe into docker-compose.yml • Then run: docker-compose up • To stop: docker-compose down https://docs.docker.com/compose/overview/
