This document summarizes a presentation about deploying microservices applications with Docker. The key points are: - Microservices break applications into small, independent services that communicate over a network. Containers automate deploying applications as lightweight, portable packages. - Docker solves issues like dependency problems and allows building once and running anywhere through containerization. A container pipeline shows the flow from base images to developer apps to operations. - Docker Compose allows running a multi-container microservices app with one command by defining services and their dependencies in a compose file. - The presenter demonstrates a sample Node.js microservices app deployed with Docker Compose, linking services like Nginx, Node apps

• Microservices
• Containers
• A container pipeline
• Docker-compose
• Use-case
• Demo

3. Microservices

4. Containers
“automates the deployment of any
application as a lightweight, portable,
self-sufficient container that will run virtually
anywhere”

5. What are containers?
OS virtualization
Process isolation
Automation
Images

6. Why use Docker?
With Docker we can solve many problems
• “it works on my machine”
• reducing build & deploy time
• Infrastructure configuration – automation!
• Libs dependency hell
• Cost control and granularity

13. Docker-compose
Get an microservices app running in one command!

14. Use-case

15. docker-compose file
nginx:
build: ./nginx
links:
- node1:node1
- node2:node2
- node3:node3
ports:
- "80:80"
node1:
build: ./node
links:
- redis
ports:
- "8080"
node2:
build: ./node
links:
- redis
ports:
- "8080"
node3:
build: ./node
links:
- redis
ports:
- "8080"
redis:
image: redis
ports:
- "6379"
