docker-stack.yml 无效的卷类型绑定

Question

这是我的 docker-stack.yml 文件

    version: "3"

    services:
      mysql:
        image: mysql:latest
        deploy:
          replicas: 1
          update_config:
            parallelism: 1
          restart_policy:
            condition: on-failure
        ports:
          - "3306:3306"
        environment:
          MYSQL_ROOT_PASSWORD: <Censored>
          MYSQL_USER: <Censored>
          MYSQL_PASSWORD: <Censored>
        volumes:
          - ./db/data:/var/lib/mysql
          - ./db/logs:/var/log/mysql
          - ./db/config:/etc/mysql/conf.d
      php:
        image: wiput1999/php
        volumes:
          - ./web:/web
      nginx:
        image: nginx:latest
        ports:
          - "80:80"
          - "443:443"
        volumes:
          - ./code:/code:ro
          - ./site.conf:/etc/nginx/conf.d/default.conf
          - /etc/letsencrypt:/etc/letsencrypt
          - ./nginx/log:/var/log/nginx

当我运行以下堆栈时，我得到 mysql 和 nginx 并出现此错误 "invalid mount config for type "bind": 绑定源路径不存在"

我不知道我的代码有什么问题。

Answer 1

bind 是一种挂载类型，用于将主机上的目录（或文件）挂载到到容器中。您所有的卷都是这样设置的。因此，您的源目录（或文件）之一不存在主机上。检查每一项：

./db/data
./db/logs
./db/config
./web
./code
./site.conf
/etc/letsencrypt
./nginx/log

您可以执行 ls -ld ./db/data ./db/logs ./db/config ./web ./code ./site.conf /etc/letsencrypt ./nginx/log >/dev/null 并查看错误消息以找出是哪一个。

Answer 2

请考虑使用 docker 配置和 docker 机密代替卷。

version: "3.3"

services:
  nginx:
    configs:
      - source: nginx_vhost
        target: /etc/nginx/conf.d/default.conf
    secrets:
      - ssl_private_key
...

configs:
  nginx_vhost:
    file: ./site.conf

secrets:
  ssl_private_key:
    file: /etc/letsencrypt/private.key
