Jenkins-AWS-terraform

This repository is for a POC of Jenkins into EC2 instance on AWS, using terraform, template file init and Ansible.

Terraform

Install Terraform, need version 0.12 or superior.

• Over CentOS7:

sudo yum update && sudo yum install wget unzip -y
export VERSION=0.12.25
sudo wget https://releases.hashicorp.com/terraform/${VERSION}/terraform_${VERSION}_linux_amd64.zip -P /tmp
sudo unzip /tmp/terraform_${VERSION}_linux_amd64.zip -d /usr/local/bin/

• Over Mac:

brew install terraform

• Over Ubuntu:

sudo apt-get update && sudo apt-get install wget unzip -y
export VERSION=0.12.25
sudo wget https://releases.hashicorp.com/terraform/${VERSION}/terraform_${VERSION}_linux_amd64.zip -P /tmp
sudo unzip /tmp/terraform_${VERSION}_linux_amd64.zip -d /usr/local/bin/

• Setup with terraform cli:

terraform init && terraform plan
terraform apply -auto-approve

Ansible

Install Ansible

• Over CentOS7:

sudo yum install -y epel-release && sudo yum install -y ansible

• Over Mac:

brew install ansible

• Over Ubuntu:

sudo apt-get update && sudo apt-get install ansible -y

Once terraform apply was run, send next command for install apache to remote server using Ansible.

• Depending of your AWS AMI will be the user.
• Change the host in the setup.yaml and file hosts
• Change in install_apache.sh bash script the new ServerName

ansible-playbook setup.yml --user=ec2-user -i hosts

Important Notes:

• You must create a ssh key pair using ssh ssh-keygen look at the variable "ssh_key" into variables.tf
• This is a POC, try to use a pipeline and service account for the credentials, or use git-crypt.
