These are Terraform modules that deploy Jenkins on Oracle Cloud Infrastructure (OCI).
The Jenkins Oracle Cloud Infrastructure Module provides a Terraform-based Jenkins cluster installation for Oracle Cloud Infrastructure (OCI). Jenkins is a distributed automation server, generally associated with Continuous Integration (CI) and Continuous Delivery (CD). A Jenkins cluster typically involves one or more Controller instance(s) coupled with one or more Agent instance(s).
- Download and install Terraform (v0.14 or later)
- Download and install the OCI Terraform Provider (v2.0.0 or later)
- Export OCI credentials. (this refer to the https://github.com/oracle/terraform-provider-oci )
- An existing VCN with subnets, and those subnets need internet access in order to download Java and Jenkins.
A Module is a canonical, reusable, best-practices definition for how to run a single piece of infrastructure, such as a database or server cluster. Each Module is created using Terraform, and includes automated tests, examples, and documentation. It is maintained both by the open source community and companies that provide commercial support. Instead of figuring out the details of how to run a piece of infrastructure from scratch, you can reuse existing code that has been proven in production. And instead of maintaining all that infrastructure code yourself, you can leverage the work of the Module community to pick up infrastructure improvements through a version number bump.
Each Module has the following folder structure:
- root: This folder contains a root module calls jenkins-controller and jenkins-agent sub-modules to create a Jenkins cluster in OCI.
- modules: This folder contains the reusable code for this Module, broken down into one or more modules.
- examples: This folder contains examples of how to use the modules.
- quick_start: This is an example of how to use the terraform_oci_jenkins module to deploy a Jenkins cluster in OCI by using an existing VCN, Security list and Subnets + Bastion Host.
- bastion_service: This is an example of how to use the terraform_oci_jenkins module to deploy a Jenkins cluster in OCI by using an existing VCN, Security list and Subnets + OCI Bastion Service.
To deploy Jenkins Cluster servers using this Module:
module "jenkins" {
source = "github.com/oci-quickstart/oci-quickstart-jenkins"
compartment_ocid = "${var.compartment_ocid}"
controller_ad = "${var.controller_ad}"
controller_subnet_id = "${var.controller_subnet_id}"
agent_count = "${var.agent_count}"
agent_ads = "${var.agent_ads}"
agent_subnet_id = "${var.agent_subnet_id}"
ssh_authorized_keys = "${var.ssh_authorized_keys}"
ssh_private_key = "${var.ssh_private_key}"
}
