• Provider.tf To configure the provider, project and the backend for the terraform (Bucket).
• Variables.tf All terraform variables types definiation.
  • Create variables without type to act as type any.
• prod.tfvars Production variables.

1. apis module Enable and disable apis

• Comopute api.
• Container api.

2. network module Configure network on GCP

• Create VPC.
• Partation the network using subnets.
• Create route.
• Create nat .
• Configure firewall.

3. cluster module Configure cluster

• Create service account .
• Create Cluster.
• Create node pool with image type UBUNTU_CONTAINERD (Docker).

cd terraform 
terraform init
terraform terraform workspace new production
terraform plan --var-file=prod.tfvars
terraform apply --var-file=pord.tfvars 

• Starting the naming with number to make files ordered.
• Create namespace to isolate the components.
• Create role to enable the jenkins pod to create, list, delete services and deployments.
• Create service account to be attached in the deployment.
• Create role bind to bind the role with service account.
• Create service loadbalancer to create loadbalacer with external ip to access the application.

• Create deployment that contains:

  • Container with jenkins image with container port 8080.
  • Mount volume to use the Docker of the node.
  • Attach the service account to make pod create deployments and services in the same cluster
  • Execute commands to install docker cli and kubectl after pod started using lifecycle.
  • Create the pod with root privilege.
