I tried to resolve that problem. When I finish my exercise I got “‘python’ container seems down or missing on app server 2”.
I was on stapp02 and yaml file was:
version: '2'
services:
web:
build: ./app
container_name: python
ports:
- "5000:5000"
volumes:
- ./app:/code
depends_on:
- redis_app
redis_app:
image: redis
container_name: redis
