4. Outline Light Intro to Cloud Docker: What, Why & How Google Cloud Platform & Docker Live Demo Learning Resources Q&A
5. Cloud Computing A LIGHT INTRODUCTION
6. Cloud Computing • On-demand access to computing resources, including servers, storage and networking infrastructure, hosted at a remote data-center • "Someone else's computer"
7. Technology Verticals • Web & Mobile • ML / AI • Distributed Systems • Internet of Things • Mixed Reality
8. Technology Verticals • Web & Mobile • ML / AI • Distributed Systems • Internet of Things • Mixed Reality CLOUD

10. Docker THE WHAT, WHY AND HOW
11. Docker is becoming a fundamental tool for Professional Developers “  StackOverflow Developer Survey 2022  2019 2020 2021 2022 69% 49% 39% 35%
12. Docker – The What • "An open-source platform for containerizing applications and environments" • Docker Image: • Set of commands describing how to run your app • Write once, run anywhere • The "ABCs" of your Cloud journey
13. Docker – The Why • Imagine buying a new computer • You set it up and install apps • Run system updates, etc. • Software: • Repeat steps on every fresh deploy • Manually run updates • Fix broken steps
14. Docker – The Why • Ship code faster • Standardize operations • Save money • Simplify security • Run and deploy anywhere
15. Docker – The How • Install Docker • Create a Dockerfile • Write steps to run app • Run it!
16. Example – Java App FROM openjdk:8-jdk-alpine # Copy code WORKDIR /app COPY . . # Compile app RUN ./gradlew build RUN mv ./build/libs / * .jar ./app.jar # Start app CMD ["java", "-jar", "/app/app.jar"]
17. Example – React App FROM node:16-alpine # Copy code WORKDIR /app COPY . . # Build app RUN npm ci RUN npm run build # Start the app CMD ["npx", "serve", "build"]
18. Build and Run # Run Java App docker build -t demo-java:v1 . docker run -it -p 8080:8080 demo-java:v1 # Run React app docker build -t demo-react:v1 . docker run -it -p 3000:3000 demo-react:v1
19. Live Demo DOCKER IN ACTION
20. Google Cloud MADE EASY WITH DOCKER
21. Google Cloud Platform • IaaS: Infrastructure as a Service • One of the "Big 3" • Servers, Storage, Databases, Networking, etc. • Extremely powerful
22. GCP + Docker • World-class support for Docker • Cloud-native tooling • Build, Deploy and Run any Docker image • Simple experience
23. Save Images to Cloud Registry # Setup gcloud login gcloud config project set ${PROJECT_ID} # Build and Save Image gcloud builds submit \ - - tag=gcr.io/${PROJECT_ID}/demo-react:v1 .
24. Deploy with Cloud Run • Instantly deploy any container • Very simple UI • Deploy previously uploaded
25. Live Demo GCP CLOUD RUN WITH DOCKER
26. Helpful Resources KEEP LEARNING Docker • Official Docs: docs.docker.com • Friendly Guides: vsupalov.com/docker/ • Dockerfile Generator: cloudup.dev Google Cloud • Container Registry: cloud.google.com/container-registry/ • Cloud Run: cloud.google.com/run/docs/
