Docker Swarm - don't restart service on entrypoint success

问题

在尝试在Docker Swarm上部署我的应用程序时，我有两个服务：NGINX用于提供静态文件，app用于编译一些静态文件。为了运行静态文件编译，我在Compose文件中使用entrypoint。

docker-compose.yml：

  1. version: "3.9"
  3. services:
  4.   nginx:
  5.     image: nginx
  6.     healthcheck:
  7.       test: curl --fail -s http://localhost:80/lib/tether/examples/viewport/index.html || exit 1
  8.       interval: 1m
  9.       timeout: 5s
  10.       retries: 3
  11.     volumes:
  12.       - /www:/usr/share/nginx/html/
  13.     deploy:
  14.       mode: replicated
  15.       replicas: 1
  16.       placement:
  17.         constraints:
  18.           - node.role == manager
  19.     ports:
  20.       - "8000:80"
  21.     depends_on:
  22.       - client
  24.   client:
  25.     image: my-client-image:latest
  26.     restart: "no"
  27.     deploy:
  28.       mode: replicated
  29.       replicas: 1
  30.       placement:
  31.         constraints:
  32.           - node.role == manager
  33.     volumes:
  34.       - /www:/app/www
  35.     entrypoint: /entrypoint.sh

entrypoint.sh：

  1. ./node_modules/.bin/gulp compilescss

我尝试在我的服务中添加了 restart: "no"，但是服务在entrypoint完成后仍然重新启动。

When trying to deploy my app on Docker swarm I have two services: NGINX to serve static files and app to compile some static files. To run static files compilation I'm using entrypoint in Compose file.

docker-compose.yml:

  1. version: "3.9"
  3. services:
  4.   nginx:
  5.     image: nginx
  6.     healthcheck:
  7.       test: curl --fail -s http://localhost:80/lib/tether/examples/viewport/index.html || exit 1
  8.       interval: 1m
  9.       timeout: 5s
  10.       retries: 3
  11.     volumes:
  12.       - /www:/usr/share/nginx/html/
  13.     deploy:
  14.       mode: replicated
  15.       replicas: 1
  16.       placement:
  17.         constraints:
  18.           - node.role == manager
  19.     ports:
  20.       - "8000:80"
  21.     depends_on:
  22.       - client
  24.   client:
  25.     image: my-client-image:latest
  26.     restart: "no"
  27.     deploy:
  28.       mode: replicated
  29.       replicas: 1
  30.       placement:
  31.         constraints:
  32.           - node.role == manager
  33.     volumes:
  34.       - /www:/app/www
  35.     entrypoint: /entrypoint.sh

entrypoint.sh

  1. ./node_modules/.bin/gulp compilescss

I tried adding restart: "no" in my service, but service is restarted on entrypoint completion anyway

Docker 23.0.0 现已发布。因此，您有两个选项：

  • stack 文件现在支持 Swarm 任务。Swarm 了解这些任务会运行到完成，即 mode: replicated-job。

  • Docker Compose V3 参考文档 明确指出 "restart:" 适用于 Compose，而 "deploy.restart_policy.condition: on-failure" 则是等效的 Swarm 语句。

英文:

Docker 23.0.0 is now out. As such you have two options:

  • stack files now support swarm jobs. Swarm understands that these run to completion. i.e. mode: replicated-job.

  • Docker Compose V3 Reference makes it clear that "restart:" applies to compose and "deploy.restart_policy.condition: on-failure" is the equivalent swarm statement.
