Oracle for Developers: Microservices on Kubernetes and Autonomous Database
This workshop will walk you through the steps to set up a Continuous Integration / Continuous Delivery (CI/CD) environment for developing Microservices, based on the automation possible in Oracle Developer Cloud and deploying all components on Oracle’s Managed Container platform and the Oracle Autonomous Transaction Processing database.
Part 1: Introduction to Oracle Cloud Infrastructure (OCI) and Autonomous Transaction Processing (ATP).
Part 2: Provisioning an Autonomous Transaction Processing Database Instance using the OCI Console. This part walks you through the steps to get started using the Oracle Autonomous Transaction Processing Database on Oracle Cloud Infrastructure (OCI):
- Sign in to Oracle Cloud Infrastructure console
- Create a Compartment
- Create an ATP Instance
Part 3: Secure Connectivity and Data Access
- Download the secure connection wallet for your provisioned instance
- Connect to the ATP instance with SQL Developer
Part 4: Setting up Developer Cloud Project
- Create a project environment
- Fetch and review code from the Git repository
- Cloning repository on local machine
Part 5: Data Loading into ATP. In this part, you will be creating a few tables and inserting data into the ATP database using the CI/CD features of Developer Cloud. We’ll use the Build engine of DevCS to set up a flow that will create the necessary objects in the database, and insert data into the tables. In case these elements are changed in the repository, the script will trigger again and re-create the database element
- Set up ATP Wallet in Developer Cloud
- Create and load data in the database
- Set up a DeleteDBObjects job and automate a Pipeline
Part 6: Setup your Managed Kubernetes Instance. This part describes how to instantiate an Oracle Managed Kubernetes cluster using Terraform, including all the required network elements such as VNC’s, subnets and access lists
- Create a Compartment for Kubernetes nodes
- Add a Policy Statement for OKE (Container Engine for Kubernetes)
- Create an API user with a certificate
- Collect Infrastructure Info for your environment
- Set the Terraform parameters and run the script
- Validate and connect to the Kubernetes cluster
Part 7: Build a Container image with the application running on ATP. In this part, you’ll learn how to build a Docker image for a Node.js REST service on Oracle Developer Cloud Service (DevCS), using an ATP database as it’s data source.
- Configure the connection to OCIR Docker Repository
- Configure the Docker build job for building container
- Execute the Docker commands
- Configure scripts to point environment
- Run the Build Job
Part 8: Deploy container on top of Kubernetes Cluster. In this section you will create a second build job to run the container you created on the Kubernetes Cluster you set up.
- Set up Deploy Build Job
- Configure the environment to point to cloud instance
- Execute and validate new job
- Installing Kubectl and visualizing the service to obtain the URL of application
The main goal of this workshop is to introduce participants with main concepts of CI/CD for developing Microservices, Oracle’s Managed Container platform and Autonomous Database.
