    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

    Ensure data is saved correctly

    请填写重现步骤部分

    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

    This is exactly what restart is about

    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-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

    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

    IIUC 您希望quickadmin在重新启动服务时重新启动服务mysql。 那么这restart就是您所需要的

    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

    thanks for reply

    i want to support depends_on in docker compose restart

    do not specify a service name

    restart do support depends_on.

    Please provide a minimal example with the actual behavior and what you expect to be the desired behavior

    thank you for your patience

    look at this code, it is my application
    after receiving the signal, it writes some data to the database

    main.go

    package main

import (
	"database/sql"
	"errors"
	"fmt"
	"log"
	"os"
	"os/signal"
	"syscall"
	"time"

	"github.com/go-sql-driver/mysql"
)

func main() {
	c := mysql.Config{
		User:   "root",
		Passwd: "password",
		Net:    "tcp",
		Addr:   "mysql:3306",
		DBName: "example",
	}
	db, err := sql.Open("mysql", c.FormatDSN())
	if err != nil {
		log.Fatal(err)
	}
	defer db.Close()

	// make sure the table exists
	_, err = db.Exec("CREATE TABLE IF NOT EXISTS counter (id INTEGER PRIMARY KEY AUTO_INCREMENT, create_at VARCHAR(255))")
	if err != nil {
		log.Fatal(err)
	}

	// print the last record
	var (
		id       int
		createAt string
	)
	err = db.QueryRow("SELECT id, create_at FROM counter ORDER BY id DESC LIMIT 1").Scan(&id, &createAt)
	if err != nil && !errors.Is(err, sql.ErrNoRows) {
		log.Fatal(err)
	}
	fmt.Println("id:", id, "create_at:", createAt)

	// wait for OS signal, then write some data to the database
	signals := make(chan os.Signal, 1)
	signal.Notify(signals, syscall.SIGTERM, syscall.SIGINT)

        // !!! this is important
	<-signals
	_, err = db.Exec("INSERT INTO counter (create_at) VALUES (?)", time.Now().Format(time.DateTime))
	if err != nil {
		log.Fatal(err)
	}
}

WORKDIR /app
COPY . .

#ENV GOPROXY='https://goproxy.cn,https://goproxy.io,direct'

RUN go build -o myapp .
CMD ["./myapp"]

    let's run it

    docker-compose up -d --build

    then run

    docker-compose down # because of depends_on the data is preserved

    run as a comparison

    docker-compose restart # data saving failed

    Even I am facing the same issue. While 'systemctl restart docker' its restarting all the containers simultaneously but not considering depends_on and not spinning up the containers in a proper order. Is this issue fixed ? Please let me know.

    @PrawinPracash systemctl restart docker is unrelated to docker compose. This restarts docker daemon, so all container will be restarted at once. depends_on is a compose-only feature, that only applies to docker compose .. commands, engine isn't aware of such dependencies.
