Restart a docker container periodically with docker-compose

docker-compose.yml

version: '3'
services:
  app:
    image: nginx:alpine
    ports: ["80:80"]
    restart: unless-stopped

  restarter:
    image: docker:cli
    volumes: ["/var/run/docker.sock:/var/run/docker.sock"]
    command: ["/bin/sh", "-c", "while true; do sleep 86400; docker restart app_app_1; done"]
    restart: unless-stopped

What is the exact container name that we should specify? The restarter is telling me no such container

Looks like you can specify the container name using the container_name attribute under the service.

So the example can actually be modified to

version: '3'
services:
  app:
    image: nginx:alpine
    ports: ["80:80"]
    container_name: app_app_1
    restart: unless-stopped

  restarter:
    image: docker:cli
    volumes: ["/var/run/docker.sock:/var/run/docker.sock"]
    command: ["/bin/sh", "-c", "while true; do sleep 86400; docker restart app_app_1; done"]
    restart: unless-stopped
    ```

How could I this be used to just restart a portainer container after a system reboot - possibly with a 20 sec delay after the reboot has happened
