+- Using CronJob to get AWS creds from the node, login to ECR, and store the secret for pulling images.
+- CronJob doesn't start immediately, need to wait a minute.
 - Need to untaint control plane node in other to schedule pods.
 - Need to build the frontend image for ARM, obviously.
+- Python app fails because it can't find the UTC timezone.
+- Cannot change deployment matching labels.
 
 At the end we're able to execute the following kubectl on the EC2 instance to deploy the app and watch it working:
 
 ```bash
 kubectl apply -f k8s/ecr-credentials.yaml
 kubectl apply -f frontend/k8s/manifest.yaml
 
-```
+curl $(kubectl get svc frontend -o=jsonpath='{.spec.clusterIP}'):8000
