Demo

• docker run -it joshkurz/matrix

Docker Commands

• docker build
• docker push/pull
• docker run
• docker logs
• docker ps
• docker start
• docker stop
• docker exec
• docker diff

Image v Container

• image == static binary
• container == isolated processes
• images are immutable
• containers are ephemeral
• containerN = new Container(image)

Inspect Matrix

# build the container
docker build .

# run matrix in the background with -d
# allocate tty with -t
docker run -t -d matrix

# execute a command in the container and get a bash shell running
# this gives us access to the internals of the running container
docker exec -it $containerid /bin/bash
touch foobar
exit

# show diff of filesystem
docker diff $containerid

# start new container
docker run -it -d matrix

# show both contianers
docker ps
# stop each container
docker stop $containerid
docker stop $containerid2
# show that both of thier instances are left over and can be restarted
docker ps -a
# remove all containers
docker rm $(docker ps -qa)

Inception Demo

docker build -t joshkurz/docker-ftw-demo
docker run -it -p 3000:3000 joshkurz/docker-ftw-demo

Docker's Adoption

• Accessability
• Portability
• Open Source
• Community 
• Marketing

Docker FTW

# run twitter-stream on local

kubectl apply -f deployment.secrets

Future Of Docker

• Microsoft Adoption
• Orchestration battle
