11. Continuous Integration / Delivery
Overview● Continuous Integration (CI)
○ build iteratively and test software automatically and regularly
○ develop cohesive & defensive software & innovate more
rapidly
● Continuous Delivery (CD) — make defined & automated
releases or deliveries into the target environment
● End to end automated CI/CD process reflects the maturity of
an organization’s development processes

17. Containerized Jenkins
docker service create
--name jenkins
--detach=true
--mount type=bind,source=/opt/jenkins_home,destination=/var/jenkins_home,ro=0
--mount type=bind,source=/var/run/docker.sock,destination=/var/run/docker.sock,ro=1
--mount type=bind,source=/usr/bin/docker,destination=/usr/bin/docker,ro=1
--mount type=bind,source=/etc/pki/ca-
trust/source/anchors/dtr.noop.ga.crt,destination=/root/.docker/tls/dtr.noop.ga/ca.crt,ro=1
--mount type=bind,source=/home/ec2-user/.docker/trust,destination=/root/.docker/trust,ro=0
--mount type=bind,source=/opt/docker/bundle,destination=/root/.docker/bundle,ro=1
--mount type=tmpfs,destination=/root
--mount type=tmpfs,destination=/tmp
--publish mode=host,target=8080,published=39999
--user root
--workdir /var/jenkins_home
--env JAVA_OPTS="-Xms2048m -Xmx2048m"
--constraint 'node.labels.role == ci-server'
dtr.noop.ga/intranet/jenkins:latest

18. Rolling Updates and Automated
Rollbacks• Rolling updates rules are applied
when updating one or more service
attribute (image, network,
published port, etc)
• Rollback rules are applied when a
rolling update fails

19. Key Takeaways
• Applications running on Docker can be integrated with any
CI/CD tool
• Integration with CI/CD need not be a complex exercise
• Running a Dockerized application does not need teams to
reengineer their development or CI/CD processes
• Features such as blue/green deployments or rolling
updates & rollbacks are provided natively through docker
