Containers: Docker and compose

Quiz: several containers

Question 9 of 10

Read the output

In compose.yaml api's `APP_PORT` was changed to 8080, and its health check stayed the same. What happened?

$ sudo docker compose up -d
 Container notes-api-1  Recreate
 Container notes-api-1  Recreated
 Container notes-proxy-1  Running
 Container notes-api-1  Starting
 Container notes-api-1  Started
 Container notes-api-1  Waiting
 Container notes-api-1  Error
dependency failed to start: container notes-api-1 is unhealthy

compose.yaml has a syntax error.
The health check still talks to port 8000 — api became unhealthy, and proxy waits for a healthy api.
proxy crashed.
api did not start because port 8080 is taken.
