Jenkins AMI using Packer and env setup using Terraform.

• Dockerised Jenkins
• Pre-configured with preloaded plugins
• Pre-configured with login username/pass
• Pre-configured with a test job

Build a quick, immutable jenkins image with all bootstrap files inside the image.

$ cd packer
$ packer build jenkins.json

AMI created from the above step gets auto picked up in the terraform. Run terraform init, plan and apply.

$ cd ../terraform/
$ terraform init
$ terraform plan
$ terraform apply

• Access jenkins with https://<EC2_Public_DNS_NAME>:8080
• One can add more required plugins to packer/bootstrap/plugins.txt file to pre-configure the jenkins with that plugin
• One can change usename/password to login to jenkins by changing "hudsonRealm.createAccount("admin", "admin")" entry in packer/bootstrap/security.groovy file
• Additional jobs can be added by adding jobs config.xml under the folder packer/bootstrap/jobs/<job_name>

P.S: Docker build may take 2-5 mins (or longer) as it needs to download all the latest plugins (mentioned in plugins.txt). Keep an eye on /var/log/bootstrap.log file to see if bootstrapng has completed successfully
