The document outlines the use of Docker in CI/CD workflows, highlighting its role in application modernization and DevOps. It discusses Docker's evolution into the enterprise, its capabilities for managing diverse applications, and the benefits of using Docker EE for continuous integration and delivery processes. Key features such as rolling updates, automated rollbacks, and integration with various CI/CD tools are also emphasized.
Using Docker EE in a CI/CD Workflow
- 1. Eric Tan Solutions Engineer, Docker Using Docker EE in a CI/CD Workflow
- 2. Agenda • Who we are • Docker - An evolution into the Enterprise • Overview of CI/CD • CI / CD Workflow • Enterprise CI / CD with Docker
- 3. • Founded in 2013 as a Linux developer tool • Fundamentally solves the “works on my machine” problem • Container industry inventor, leader and innovator • Transform app and infrastructure security, portability, agility and efficiency Docker is the leading software container platform App Modernization DevOpsCloud Docker at the center of major IT strategies
- 4. Docker Hosts 14M Growth in Docker job listings 150% Image pulls Over 390K% Growth 12B Docker apps 900K Project Contributors 3300 Docker Momentum in Three Years
- 5. Evolution of the Docker Platform Many purposes, users and infrastructure Today Developer Community Need to experiment and innovate with leading edge tech Ops Community Enterprise Partner Ecosystem Run business critical apps at scale anywhere Extend and add value to a platform with a shared path to monetization Need a predictable system to deploy and run apps
- 6. Open Source Community Edition (CE) Enterprise Edition (EE) Small DIY teams to started with Docker Free to use and available for desktop, cloud and community Linux distros Includes swarm mode orchestration, security and networking. Advancing the container industry with new open source projects LinuxKit Toolkit for building secure, lean and portable Linux subsystems Moby Project Library of components and framework for container ecosystem Enterprise IT teams that build and run critical apps at scale in production Subscription (software, support and certification) for cloud, enterprise x86, mainframe Linux and Windows Server 2016 Includes integrated orchestration, management, security and access control.

- 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
- 12. DEVELOPERS IT OPS BUILD Development Environments SHIP Secure Content & Collaboration Developers Version control Registry (Docker hub / DTR) QA / Staging / Prod Continuous Integration & Delivery Workflow Testers / Users RUN All environments

- 15. Build Images Deploy Applications (stacks) ● docker pull (from store) * ● Dockerfile (multi-stage build) ● docker build -f Dockerfile . ● client-bundle.zip* ● compose.yml* (docker-compose / docker stack) ● Secrets ● Routing Mesh Image Distribution● docker tag ● docker login ● docker push

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
