Verify Your Deployment

Confirm your AWS deployment is working

After running ag infra up prd:aws, verify everything is working before proceeding.

Check the Health Endpoint

Get your load balancer DNS from the AWS Console (EC2 → Load Balancers), then:

curl http://[LOAD_BALANCER_DNS]/health

Expected response:

{ "status": "ok", "instantiated_at": "2025-01-01T12:00:00Z" }

Check CloudWatch Logs

aws logs tail {infra_name}-prd-api --follow

Look for these lines indicating successful startup:

INFO:     Started server process [1]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:8000

Replace {infra_name} with your infra_name from settings.py (e.g., agentos-aws-template).

Check ECS Service Status

aws ecs describe-services \
  --cluster {infra_name}-prd \
  --services {infra_name}-prd-api-service \
  --query 'services[0].{status:status,running:runningCount,desired:desiredCount}'

Expected output:

{
  "status": "ACTIVE",
  "running": 1,
  "desired": 1
}

What Success Looks Like

Check	Expected
Health endpoint	Returns {"status": "ok", ...}
CloudWatch logs	Shows “Application startup complete”
ECS service	Running count matches desired count
Load balancer targets	Shows “healthy” in AWS Console

If Something Is Wrong

Symptom	Next Step
Health returns error	Check CloudWatch logs
No logs appearing	Check ECS task started in AWS Console
Task keeps restarting	See Troubleshooting
