For a week now I've been trying to get my mono configuration running with apache. I must have tried virtually anything, shamefully I notice no changes, the problem remains the same.

阅读更多关于 AWS ECS 503 Service Temporarily Unavailable while deploying

I am using Amazon Web Services EC2 Container Service with an Application Load Balancer for my app. When I deploy a new version, I get 503 Service Temporarily Unavailable for about 2 minutes.

UPDATE: The health check numbers for the target group of the ALB are the following: Healthy threshold: 5 Unhealthy threshold: 2 Timeout: 5 seconds Interval: 30 seconds Success codes: 200 OK
