This is a simple demo showing how to spinning up an aws instance on EC2 with Jenkins setup. The network structure is as following:
From here, you can further:
- converted this into a cluster by adding ASG and ELB.
- use templating tool such as Packer to create an AMI and save on S3, then provision with terraform
- Terraform - orchestration tool to provision servers and network on aws
- Puppet - configuration tool to provision Jenkins
- Jenkins CLI - interacting with Jenkins to create user account
We need install go and terraform:
- Install go (required by Terraform)
**
brew install go - Install terraform
- You have to have full access of EC2 (for provisioning) and S3 (for saving terraform state)
- You generate a EC2 key pair named JenkinsKeyPair (or others, then you need change vars.tf file), and save private key to /path/to/JenkinsKeyPair.pem with permission
400. - You need update modules/terraform.tfvars file to your aws access key and secret key, plus the private key path.
Please refer to modules/ec/run.sh.
- To initialize, use
run.sh init. - To apply, use
run.sh apply. When finish, it should print the dns of the jenkins server. You can copy and paste that to browser, e.g., http://ec2-12-34-56-78.compute-1.amazonaws.com:8080. The default user isalexli, and password ispassword. - To destroy(do NOT forget), use
run.sh destroy

The following is the graph output from terraform:
