Build once,run anywhere


Configure once, run anywhere


Example of using Docker4 build documentation in Sphinx with latex support

4 executing code in many different programming languages without requiring a single compiler or script interpreter on your machine - docker exec

4 running gui app in docker at linux

Example of using Docker4 development without install ing many tools at local machine

4 Vagrant, Otto dev

4 continues integration using docker

4 Jenkins, TravisCI, CircleCI

4 DevOps platform for build, deploy and manage apps across any cloud

VM vs Docker


Containers and imagesdocker run hello-world


Docker Remote API4 client & server in Docker

4 docker ps

4 docker build

4 docker push/pull

4 docker run/stop

4 docker inspect


Docker lifecycle4 a build produces an immutable image

4 a container is as instance of the image

Docker tools


Docker compose

4 defining and running multi-container applications with Docker


docker-compose.ymlweb: build: . ports: - "5000:5000" volumes: - .:/code links: - redisredis: image: redis


Docker machine4 Machine lets you create Docker hosts on your

computer, on cloud providers, and inside your own data center.

4 part of Docker toolbox

4 replacement for boot2docker


Docker swarm

4 Docker Swarm is native clustering for Docker.

4 Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Flynn, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.


Kitematic4 desktop GUI for Docker

4 Mac and Windows only


Docker Trusted Registry (DTR)4 private dedicated image registry


Docker Cloud4 Deploy and scale any application to your cloud in

seconds, with just a few clicks




Docker isn't just Docker Inc


Alternatives for Docker Registry4 Amazon EC2 Container Registry

4 Google Container Registry

4 Quay Enterprise

4 Artifactory

4 Nexus

# Test the project - script: name: go test code: go test ./...

# Statically build the project - script: name: go build code: CGO_ENABLED=0 go build -a -ldflags '-s' -installsuffix cgo -o app .

# Copy binary to a location that gets passed along to the deploy pipeline - script: name: copy binary code: cp app "$WERCKER_OUTPUT_DIR"


Docker in AWS4 Elastic Beanstalk

4 EC2 Container Service (ECS)

4 EC2 with Swarm, Mesos or Kubernetes


http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_dockerpreconfig.walkthrough.html?carousel=true

https://aws.amazon.com/ecs/

http://mesos.apache.org/

http://kubernetes.io/



Apache Messos4 Scalability to 10,000s of nodes

4 Fault-tolerant replicated master and slaves using ZooKeeper

4 Support for Docker containers

4 Native isolation between tasks with Linux Containers

4 Multi-resource scheduling (memory, CPU, disk, and ports)

4 Java, Python and C++ APIs for developing new parallel applications

4 Web UI for viewing cluster state


Notes at the end4 don't use Docker as VM

4 build & production images

4 tag every image using in production (not just latest)

4 big difference between languages (NodeJS & Go)

4 don't use latest Docker versions in production

4 try use dockerlint for your DockerfilesIPEX Meetup Brno, 9.3.2016 49
