I will be speaking on Jenkins integration to AWS EC2, CodeCommit, CodeDeploy, and CodePipeline. The talk location is:
Tuckahoe Library
1901 Starling Dr., Henrico, VA (map)
Jimmy Ray with AuthX Consulting will present Jenkins usage with AWS.
• Jenkins concepts
• Options for Jenkins in AWS (yum, AWS Marketplace, etc.)
• Configuring Jenkins in AWS (Setup, Plugins, Proxies(NGINX), Route 53/ELB, Security (Jenkins, Groups, SSL, etc.))
• EC2 Roles
• Jenkins Slaves
• AWS CodeDeploy
• AWS CodeCommit
• AWS CodePipeline
Jenkins has it own Pipeline plugin (formerly know as Workflow). Information can be found here:
Below is an example pipeline Groovy script that I wrote to build and deploy a CMS application from code in GitHub. Maven builds the project, and then shell scripts perform the deployment to AWS EC2 instances. Without Jenkins Pipeline, this would have been more complex involving multiple jobs. Though it still can be broken down into multiple jobs, this particular example was done in a single Jenkins job.
