7. Problem Statement – Typical Deployment
1. Scalability
2. Availability
3. Managed by IT
4. Cleanliness
5. Maintainability

8. Solution Statement
Well, kinda… how do we manage these container(s)?

9. Solution Statement (continued)
1. Building the Docker image
• Create self provisioning, ready for production Jenkins instance
2. Orchestrating the Container

10. Jenkins Architecture
MASTER
Configurations
Node
Configuration
Plugins
EXECUTORS

11. Dockerizing Jenkins Master – Basic Dockerfile
FROM jenkins/jenkins:lts
# Skip initial setup
ENV JAVA_OPTS -Djenkins.install.runSetupWizard=false
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/
plugins.txt
COPY jenkins.yaml /usr/local/jenkins.yaml
ENV CASC_JENKINS_CONFIG /usr/local/jenkins.yaml

12. Dockerizing Jenkins Master – Groovy, but not so groovy
import com.michelin.cio.hudson.plugins.rolestrategy.RoleBasedAuthorizationStrategy
import com.michelin.cio.hudson.plugins.rolestrategy.RoleMap
import com.synopsys.arc.jenkins.plugins.rolestrategy.RoleType
import hudson.security.HudsonPrivateSecurityRealm
import io.jenkins.systemgroovy.plugins.OwnershipBasedSecurityHelper
import jenkins.model.Jenkins
import jenkins.security.QueueItemAuthenticatorConfiguration
import hudson.model.*
import org.jenkinsci.plugins.authorizeproject.GlobalQueueItemAuthenticator
import org.jenkinsci.plugins.authorizeproject.strategy.TriggeringUsersAuthorizationStrategy
boolean createAdmin = Boolean.getBoolean("io.jenkins.dev.security.createAdmin")
println("=== Installing the Security Realm")
def securityRealm = new HudsonPrivateSecurityRealm(false)

14. Dockerizing Jenkins Master – the YAML approach
jenkins:
securityRealm:
bitbucket:
clientID: <hash_valuse>
clientSecret: <hash_value>
authorizationStrategy:
loggedInUsersCanDoAnything:
allowAnonymousRead: false
systemMessage: "Jenkins configured automatically!"
numExecutors: 0
scmCheckoutRetryCount: 2
………

15. Next Steps
• Finish converting everything to YAML
• Create PROD, DEV and TEST Dockerfile build stages
• Setup Kubernetes cluster as Jenkins executor pool
