Please, fill the Steps To Reproduce section

depends_on is only applied as container is created, until you explicitly declare a dependent service to require being restarted after it's dependency was updated/restarted, see https://docs.docker.com/reference/compose-file/services/#long-syntax-1

I read this document, but it doesn't solve my problem. restart = true is not what I want.

I need the dependent service to be restarted after my service

all containers restart at the same time, and operations with dependencies will fail

root@palyground:~/deploy# docker compose restart
[+] Restarting 7/7
 ✔ Container prod-mysql-1         Restarting    0.5s
 ✔ Container prod-prometheus-1    Restarting    0.5s
 ✔ Container prod-quickrest-1     Restarting    0.5s
 ✔ Container prod-nginx-1         Restarting    0.5s
 ✔ Container prod-quickproxy-1    Restarting    0.5s
 ✔ Container prod-quickadmin-1    Restarting    0.5s
 ✔ Container prod-quickservice-1  Restarting    0.5s

This is exactly what restart is about

Please provide an illustration example. Reporting issue with a single sentence and none of the requested information won't bring you the best assistance we can offer

所有容器同时重启，有依赖关系的操作将会失败

root@palyground:~/deploy# docker compose restart
[+] Restarting 7/7
 ✔ Container prod-mysql-1         Restarting    0.5s
 ✔ Container prod-prometheus-1    Restarting    0.5s
 ✔ Container prod-quickrest-1     Restarting    0.5s
 ✔ Container prod-nginx-1         Restarting    0.5s
 ✔ Container prod-quickproxy-1    Restarting    0.5s
 ✔ Container prod-quickadmin-1    Restarting    0.5s
 ✔ Container prod-quickservice-1  Restarting    0.5s

I want prod-quickadmin-1 to restart first, and then prod-mysql-1 to restart

The quickadmin service will capture the 15 signal and save some data to mysql

[ndeloof]

IIUC you want quickadmin service to be restart as you restart mysql service.
Then restart is what you need

services:
  db:
    ...
  admin:
    ...
    depends_on:
      db:
        condition: service_started
        restart: true

$ docker compose --progress=plain restart db
 Container truc-db-1  Restarting
 Container truc-db-1  Started
 Container truc-admin-1  Restarting
 Container truc-admin-1  Started
