This document outlines an agenda for a presentation on DevOps and Docker. It includes sections on Docker resources, Docker vs virtual machines, Docker stacks, Docker networking, examples of Dockerizing Node.js apps and scaling them, testing with Docker, using Docker on IBM Bluemix and Mesosphere DCOS, and next steps to explore like AWS ECS, Pivotal Web Services, and monitoring tools.

9. Docker by examples
 Para los ejemplos nos guiaremos del siguiente
repositorio:
https://github.com/davisusanibar/limaconf.git
 Node JS App:
 Ir a /wks/nodejs compilar y levantar el applicativo con:
 npm install
 node index.js

10. Node JS App

11. Docker Node JS App
 Docker Node JS App:
 Ir a /wks/docker compilar y levantar el applicativo con:
 docker build -t limaconf/nodejsapp:v1 .
 docker images
 docker run -d --name mynodejsindocker -p 8006:8003
limaconf/nodejsapp:v1
 docker ps -a | grep mynodejsindocker
 docker port 40d7a2e47712
 sh ../util/dinspect.sh
 curl 172.17.0.3:8003
 docker logs 40d7a2e47712
 docker inspect 40d7a2e47712

12. Docker Node JS App

13. Docker Node JS App

14. Scale Docker Node JS App
 Para la prueba de escalamiento usaremos las siguientes
tecnologias:
 Service Registrator: gliderlabs/registrator
 Consul Service Discovery: progrium/consul
 Load Balancer: nginx:1.7
 Ir a /wks/dockercompose compilar y levantar el applicativo
con:
 docker-compose build
 docker-compose up –d
 docker-compose logs
 docker-compose ps
 docker-compose scale app=3

19. Testing with Docker
 Jenkins (https://hub.docker.com/_/jenkins/)
 docker run -d -p 8080:8080 -p 50000:50000 jenkins
 Nginx (https://github.com/tutumcloud/hello-world)
 docker run -d -p 80 tutum/hello-world
 MySQL Master / Slave
 docker run -d -p 3306:3306 tutum/mysql
