假设我有一个json文件，我运行cat testTab.json | jq '.action.service.spec.task| select(.container) | .container'它，它给了我

{
  "image": "ubuntu:latest",
  "args1": "tail",
  "args2": "-f",
  "args3": "/dev/null",
  "mounts": {
    "source": "/home/testVolume",
    "target": "/opt"
  },
  "dns_config": null
}

我应该如何编辑此命令来获取所有参数（args1、args2 和 args3）值（“tail”“-f”“/dev/null”）

假设我们有以下堆栈文件：

version: "3"
services:
  ubuntu:
    image: ubuntu
    deploy:
      replicas: 2
      restart_policy:
        condition: on-failure
      resources:
        limits:
          cpus: "0.1"
          memory: 50M
    entrypoint:
      - tail
      - -f
      - /dev/null
    logging:
      driver: "json-file"
    ports:
      - "80:80"
    networks:
      - webnet
  web:
    image: httpd
    ports:
      - "8080:8080"
    hostname: "apache"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
    deploy:
      placement:
        constraints: [node.role == manager]
      resources:
        limits:
          memory: 32M
        reservations:
          memory: 16M
    depends_on:
      - "ubuntu"
    networks:
      - webnet
networks:
  webnet:

当我运行时docker service inspect mystack_web，生成的输出不会显示对depends_on条目的任何引用。

这样可以吗？以及如何打印给定docker服务的依赖关系？
