将 LetsEncrypt 文件复制到 docker 容器

我不是 docker 专家，我只是在习惯它。我想将主机上生成的 ssl 证书复制到我的 docker 容器。我读到它应该能够与volumesdocker-compose 文件中的参数，但启动我的服务器时它总是令人兴奋，因为它无法在工作目录中找到复制的文件。

文件夹结构

- repo
   - backend
      - api
         - static
            - ssl
         - dockerfile
   - frontend
   - docker-compose.yml

Dockerfile

FROM node:14-alpine

ENV NODE_ENV=production SERVER_PORT_HTTP=80 SERVER_PORT_HTTPS=443

WORKDIR /usr/src/app

RUN npm install

COPY . .

EXPOSE ${SERVER_PORT_HTTP} ${SERVER_PORT_HTTPS}

CMD [ "npm", "run", "start" ]

Docker-Compose

version: "3"

services:
  api:
    build:
      context: ./backend/api
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /etc/letsencrypt/live/api.example.com:/static/ssl
    restart: unless-stopped

你做的一切都是对的，问题出在文件上。如果您查看它们，您会发现它们不是普通文件，而是链接：

root@fbe56bc38ad6:/# ls /etc/letsencrypt/live/example.com/ -l
total 4
-rw-r--r-- 1 root root 692 Jul 24  2020 README
lrwxrwxrwx 1 root root  44 Mar 22 00:03 cert.pem -> ../../archive/example.com/cert5.pem
lrwxrwxrwx 1 root root  45 Mar 22 00:03 chain.pem -> ../../archive/example.com/chain5.pem
lrwxrwxrwx 1 root root  49 Mar 22 00:03 fullchain.pem -> ../../archive/example.com/fullchain5.pem
lrwxrwxrwx 1 root root  47 Mar 22 00:03 privkey.pem -> ../../archive/example.com/privkey5.pem
lrwxrwxrwx 1 root root  42 Mar  1 12:57 example.com -> /etc/letsencrypt/live/example.com
lrwxrwxrwx 1 root root  33 Mar  1 12:57 ssl-dhparams.pem -> /etc/letsencrypt/ssl-dhparams.pem

因此，您安装了一堆指向不存在位置的相对链接。

我建议你挂载/etc/letsencrypt to /etc/letsencrypt在容器中：

    volumes:
      - /etc/letsencrypt:/etc/letsencrypt

然后让您的应用程序在以下位置查找文件/etc/letsencrypt/live/example.com或建立另一个链接/static/ssl这指向/etc/letsencrypt/live/example.com:

ln -s /etc/letsencrypt/live/example.com /static/ssl
