2. Continuous delivery Docker Jenkins Questions

3. Automate everything Software quality Continuous improvement Regular deployments Anyone can deploy

4. Version control Compile Quality checks Testing Deployments DevOpsEnd users Etcetera Setup environment

6. Automate environment provisioning Automate application deployment

15. To enable continuous delivery Quickly provision environments Run the same software local and in the cloud Easy to move software Better performance Higher availability Cheaper

16. Disk space efficiency Memory efficiency Speed Compatibility (run anywhere) Isolation Versioning Internet of Things (Raspberry Pi etc.)

17. Simple general commands No Domain Specific Language (DSL) Configuration with operating system commands

18. Since March 2013 8741 commits in 15 months More than 460 570 contributors Downloaded 2.75 13 million times More than 14000 30000 Dockerized apps >6500 Docker related projects on GitHub More than 90 user groups DockerCon (Europe) Support from Google, VMWare, RackSpace, Red Hat, IBM, Microsoft etcetera

21. Docker on Ubuntu 14.04 apt-get install docker.io docker.io run -i -t ubuntu:saucy /bin/bash

23. Main directory BuildAndRunScript.sh GeneralBase Dockerfile Sonar Dockerfile

24. FROM ubuntu:saucy RUN apt-get -y install software-properties- common RUN add-apt-repository ppa:webupd8team/java RUN apt-get update && apt-get -y upgrade RUN echo "oracle-java7-installer shared/accepted-oracle-license-v1-1 boolean true" | debconf-set-selections RUN apt-get -y install oracle-java7-installer ENV JAVA_HOME /usr/lib/jvm/java-7-oracle

25. FROM GeneralBase RUN apt-get install -y wget unzip RUN wget http://dist.sonar.codehaus.org/sonarqube- 4.2.zip RUN unzip sonarqube-4.2.zip -d /opt RUN rm sonarqube-4.2.zip EXPOSE 9000 EXPOSE 9092 CMD ["/opt/sonarqube-4.2/bin/linux-x86-64/sonar.sh", "console", "/bin/bash"]

26. Create the Dockerfiles Build the containers: cd GeneralBase docker.io build -t GeneralBase. cd.. cd Sonar docker.io build -t Sonar.

27. Start the container docker.io run -p 9000:9000 –p 9092:9092 -d Sonar

28. # docker.io ps –a CONTAINER ID: ecbecf77461b CREATED: 32 minutes ago STATUS: Up 32 minutes PORTS: 0.0.0.0:9000->9000/tcp, 0.0.0.0:9092->9092/tcp

29. Start / stop / restart docker [start/stop/restart] containerid Follow SystemOut and SystemErr docker logs -f containerid

30. Show (running) containers docker ps –a Show processes running in container docker top containerid Show changes in the container docker diff containerid

31. Stop all containers docker.io stop $(docker.io ps -a -q) Remove all containers docker.io rm $(docker.io ps -a -q) Remove all images docker.io rmi $(docker.io images -q)

38. Creating the Docker registry docker run -p 5000:5000 registry

39. Modify container Commit docker.io commit 064f 192.168.56.31:5000/test-version-0.2 New containerid -> ff7e Push docker.io push 192.168.56.31:5000/test-version-0.2

40. Pull docker.io pull 192.168.56.31:5000/ test-version-0.2 Run docker.io run -i -t ff7e /bin/bash View the changed container

42. docker images -tree └─153b 194.2 MB test-version-0.1:latest docker pull 192.168.56.31:5000/test- version-0.2 ff7e: Download complete 153b: Download complete docker images -tree └─153b 194.2 MB test-version-0.1:latest └─ff7e 194.2 MB test-version-0.2:latest

46. Simple to use Really popular Used in many organizations Regular updates Big community creating plugins etc. Most developers already use it

47. 1 2 3 4 6 7 8 9 5

52. Continuous delivery Continuous deployment

57. “Life is really simple, but we insist on making it complicated.” - Confucius

59. Use a (private) Docker registry Use images from the registry instead of export Keep environmental settings separate Use Jenkins to manage everything Do not add extra functionality like OpenSSH Think about topics such as security, monitoring and logging Separate concerns in separate containers Inherit containers
