As a Developer I need a Kubernetes Cluster on IBM Cloud So that I can use it to deploy wishlist application on the cloud

Details and Assumptions

rsaim commented 1 year ago

The wishlist app is deployed to IBM cloud at 159.122.183.157:31000

  vscode@nyu:/app$ wget -O - 159.122.183.157:31000 | jq .

Steps to deploy the app to IBM cloud:

  1. Create a Kubernetes cluster nyu-devops using IBM Cloud UI
  2. Create an access token apikey.json using IBM Cloud UI
  3. Download the key to ~/.blumix/apikey.json in your local machine
  4. Start Docker on your machine
  5. Clone and "Reopen in Container" the wishlist repository in VSCode
  6. Access the terminal in docker either in VSCode or via the local terminal using command docker exec -it -u vscode nyu bash
  7. Your CWD must be /app in the container. Execute make login to login into IBM cloud. This step uses the apikey.json we downloaded earlier in step#3
  8. (Optional) Create IBM cloud registry namespace. I have used and hard-coded nyu-devops-wishlist as a part of this issue.
  9. After changing code, execute make build to create a new Docker image
  10. List local Docker images using docker image ls
  11. See the public IP to access the service using command ibmcloud cr images
  12. Push the docker image to IBM Image registry using command docker push docker push us.icr.io/nyu-devops-wishlist/wishlist:1.0. Note that we have hard-coded version 1.0 for now.
  13. Deploy the wishlist app, postgres app, and required services via the command kc apply -f deploy
  14. See the status of deployment using kc get all. Wait for the status of pods to change to READY.
  15. Get the public IP of a worker node using ic ks workers --cluster nyu-devops
  16. Acess the wishlist service using the public IP

The configuration for nyu-devops was downloaded successfully.

Added context for nyu-devops to the current kubeconfig file.
You can now execute 'kubectl' commands against your cluster. For example, run 'kubectl get nodes'.
If you are accessing the cluster for the first time, 'kubectl' commands might fail for a few seconds while RBAC synchronizes.
