如何在 docker 堆栈部署上禁用网络生成

Question

我正在通过以下方式将撰写文件部署到 UCP：

docker stack deploy -c docker-compose.yml custom-stack-name

最后我想将多个撰写文件（每个撰写文件描述一个单独的微服务的设置）部署到一个 docker 网络上，例如应用网络

version: "3"
services:

  service1:
    image: docker/service1
    networks:
      - appsnetwork

  customservice2:
    image: myprivaterepo/imageforcustomservice2
    networks:
      - appsnetwork

networks:
  appsnetwork:

docker stack deploy 命令会自动创建一个新网络，其生成的名称如下：custom-stack-name_appsnetwork

我有哪些选择？

Answer 1

首先尝试自己创建网络

docker network create --driver=overlay --scope=swarm appsnetwork

然后在你的 compose 中建立外部网络

version: "3"
services:
  service1:
    image: nginx
    networks:
      - appsnetwork

networks:
  appsnetwork:
    external: true

之后运行两份堆栈

docker stack deploy --compose-file docker-compose.yml stack1
docker stack deploy --compose-file docker-compose.yml stack2

Docker 检查同一网络中的两个显示 IP

$ docker inspect 369b610110a9
  ...
            "Networks": {
                "appsnetwork": {
                    "IPAMConfig": {
                        "IPv4Address": "10.0.1.5"
                    },
                    "Links": null,
                    "Aliases": [
                        "369b610110a9"
                    ],

$ docker inspect e8b8cc1a81ed

            "Networks": {
                "appsnetwork": {
                    "IPAMConfig": {
                        "IPv4Address": "10.0.1.3"
                    },
                    "Links": null,
                    "Aliases": [
                        "e8b8cc1a81ed"
                    ],
