Rapid delivery of software is essential for efficiently running your applications in the cloud. Oracle Cloud Infrastructure (OCI) DevOps services provide a continuous integration and deployment (CI/CD) platform for developers to easily build, test, and deploy software and applications on Oracle Cloud.

This reference architecture builds and tests a sample Node.js web application and then deploys it to OKE by using the OCI DevOps. The application source code is hosted on a DevOps code repository. The end user commits the code into the code repository, which triggers the start of a build pipeline.

The build pipeline follows a user-defined flow to build and test software, then create a container image of the latest version of the application. The output of the build is stored in the container registry as an image. Then a deployment pipeline uses the built image from the container registry and a Kubernetes manifest to deploy the most recent version of the application to OKE.

For details of the architecture, see Build a continuous integration and deployment pipeline using Oracle DevOps service

The OCI Terraform Provider is now available for automatic download through the Terraform Provider Registry. For more information on how to get started view the documentation and setup guide.

1. Click

   If you aren't already signed in, when prompted, enter the tenancy and user credentials.

2. Review and accept the terms and conditions.

3. Select the region where you want to deploy the stack.

4. Follow the on-screen prompts and instructions to create the stack.

5. After creating the stack, click Terraform Actions, and select Plan.

6. Wait for the job to be completed, and review the plan.

   To make any changes, return to the Stack Details page, click Edit Stack, and make the required changes. Then, run the Plan action again.

7. If no further changes are necessary, return to the Stack Details page, click Terraform Actions, and select Apply.

Now, you'll want a local copy of this repo. You can make that with the commands:

git clone https://github.com/oracle-devrel/terraform-oci-arch-ci-cd-devops
cd terraform-oci-arch-ci-cd-devops
ls

First off, you'll need to do some pre-deploy setup. That's all detailed here.

Secondly, create a terraform.tfvars file and populate with the following information:

# Authentication
tenancy_ocid         = "<tenancy_ocid>"
user_ocid            = "<user_ocid>"
fingerprint          = "<finger_print>"
private_key_path     = "<pem_private_key_path>"

# Region
region = "<oci_region>"

# Compartment
compartment_ocid = "<compartment_ocid>"

# OCI User and Authtoken
oci_username       = "<oci_username> 
# For a federated user (single sign-on with an identity provider), enter the username in the following format: TenancyName/Federation/UserName. 
# For example, if you use OCI's identity provider, your login would be, Acme/oracleidentitycloudservice/alice.jones@acme.com. 
#If you are using OCI's direct sign-in, enter the username in the following format: TenancyName/YourUserName. For example, Acme/alice_jones. Your password is the auth token you created previously.

oci_user_authtoken = "<oci_user_authtoken>" 
# You can get the auth token from your Profile menu -> click User Settings -> On left side  click *Auth Tokens -> Generate Token

Deploy:

terraform init
terraform plan
terraform apply

You can go to created OKE cluster, click on Access Cluster, launch Cloud Shell, run kubeconfig create command in cloud shell.

Next, run the below command.

`kubectl -n example get services` 

• where example is the namespace for the cluster.

You can copy the EXTERNAL-IP and paste it on the browser to access the Node.JS application.

When you no longer need the deployment, you can run this command to destroy it:

terraform destroy

Note: Application deployment within OKE will lead to OCI LoadBalancer provisioning, created outside the Terraform realm. Consequently, terraform destroy operation will not be able to destroy OKE as dependent LB will stay untouched. Therefore you should destroy LB from OCI Console perspective beforehand. Then you can continue with terraform destroy command.
