Jenkins Configuration as Code

Primary LanguageDockerfile

Jenkins JCasC Configuration

Prerequisites :

Create a password directory which will have all the credentials in the files like this

Password Tree

This directory is update in the docker compose file like this

Docker Compose

  • Pre-requisite for EC2 Slave

    • The ssh key should be passed into jenkins master through password directory and in docker-compose as agent-key in above image
    • Jenkins Slave EC2 should have java installed. It can be done using yum install java-openjdk -y

  • Pre-requisite for ECS Slave

    • First we have to create an IAM Role so that EC2 Jenkins master can access the ECS so for it I created a IAM Role with ECSFullAccess and TaskExecution like this.

    IAM Role

    • The task execution role is used by ECS to execute the task which the master will assign it.

    • Also important part in this IAM Role is the Trust Relationship segment. In this segment we define what are the trusted entities for this role than can use AWS STS to assumerole.

    • Thus here we add EC2 , ECS and ECS-Task as trusted entities like this.

    Trusted Entities

    • We also need to pre create a ECS Cluster whose ARN will be referenced in the Jenkins CasC file like this.

    Jcasc

    • One more thing we require is to create Log Group in the AWS CloudWatch for the ECS Agent Cluster with the same name as referenced in Jenkins CacC file.
