5. The world needs
tools of mass innovation

6. A programmable Internet would be the ultimate
tool of mass innovation

7. A commercial product,
built on
a development platform,
built on
infrastructure,
built on
standards.
Docker is building a stack to program the Internet

8. Isolation using Linux kernel features
namespaces
 pid
 mnt
 net
 uts
 ipc
 user
cgroups
 memory
 cpu
 blkio
 devices

9. Image layers

10. Dockerfile
FROM java:8
MAINTAINER Patrick Chanezon <patrick@chanezon.com>
EXPOSE 8080
COPY spring-doge/target/*.jar /usr/src/spring-doge/spring-
doge.jar
WORKDIR /usr/src/spring-doge
CMD java -Dserver.port=8080 -
Dspring.data.mongodb.uri=$MONGODB_URI -jar spring-doge.jar
HEALTHCHECK --interval=5m --timeout=3s --retries=3
CMD curl -f http://localhost:8080/ || exit 1

11. Using Docker to compile your jar/war
https://registry.hub.docker.com/_/maven/
docker run -it --rm
-v $PWD:/usr/src/spring-doge
-v maven:/root/.m2
-w /usr/src/spring-doge
maven:3.3-jdk-8
mvn package

12. Build an image
docker build -t chanezon/spring-doge .
FROM java:8
MAINTAINER Patrick Chanezon <patrick@chanezon.com>
EXPOSE 8080
COPY spring-doge/target/*.jar /usr/src/spring-doge/spring-
doge.jar
WORKDIR /usr/src/spring-doge
CMD java -Dserver.port=8080 -
Dspring.data.mongodb.uri=$MONGODB_URI -jar spring-doge.jar
HEALTHCHECK --interval=5m --timeout=3s --retries=3
CMD curl -f http://localhost:8080/ || exit 1

13. Analyzing images
docker images java
docker history java:8

14. Run a container
docker run
—env MONGODB_URI=mongodb://mongo:27017/test
-p 8090:8080
chanezon/spring-doge

15. docker-compose: running multiple containers
 Run your stack with one command: docker-compose up
 Describe your stack with one file: docker-compose.yml
version: '2'
services:
web:
image: chanezon/spring-doge
ports:
- "8080:8080"
links: ["mongo"]
environment:
- MONGODB_URI=mongodb://mongo:27017/test
mongo:
image: mongo

16. Using the service API
docker network create -d overlay dogenet
docker service create --name mongo
--network dogenet
mongo
docker service create --name doge
--network dogenet
--publish 8070:8080
--replicas 3
--env MONGODB_URI=mongodb://mongo:27017/test
chanezon/spring-doge
