Let's Encrypt SSL證書申請

當前環境：

阿里雲CoreOS
所綁定的域名，解析管理也在阿里這兒，在該文檔中使用 example.com 作爲示例。
Docker 鏡像 neilpang/acme.sh:2.8.8 https://github.com/acmesh-official/acme.sh
nginx 申請證書並使用
使用Docker-Compose
SSL證書爲泛域名證書

實際應用中可以參考下面兩篇文章：

2. Deploy certs from a container to another container 第二部分
DNS API 參考這部分 11. Use Aliyun domain API to automatically issue cert
acme.sh dns模式支持 Cloudflare, DNSPod.cn, CloudXNS.com, GoDaddy.com, Amazon Route53, Aliyun, Linode, FreeDNS, DigitalOcean 等大概一百多個域名解析提供商，本文使用的是阿里雲域名解析，申請SSL的時候會往域名解析力添加一條TXT記錄來驗證域名所有權。

目的：

在阿里雲CoreOS操作環境中綁定 Let's Encrypt SSL證書並使用。（不是很清楚使用這種方式能否實現證書自動續費，證書是3個月有效期，也許3個月之後就可以知道了。）

下載所需鏡像

個人習慣喜歡先把所需要的鏡像給下載下來，不喜歡用latest標籤，因爲覺得如果新版本有功能更新的話，會讓人迷糊。
Docker-Compose的安裝略過。

$ sudo docker pull nginx:1.19.6-alpine
$ sudo docker pull neilpang/acme.sh:2.8.8

創建`docker-compose.yml`文件

version: '3'
  
services:
  runNginx:
    image: nginx:1.19.6-alpine
    container_name: runNginx
    volumes:
      - /data/docker_config/nginx/nginx.conf:/etc/nginx/nginx.conf:ro
      - /data/docker_config/nginx/ssl:/etc/nginx/ssl
    ports:
      - 80:80
      - 443:443
    depends_on:
      - runAcmesh
    environment:
      - NGINX_PORT=80
    labels:
      - sh.acme.autoload.domain=example.com
  runAcmesh:
    image: neilpang/acme.sh:2.8.8
    container_name: runAcmesh_example.com
    command: daemon
    volumes:
      - /data/docker_config/acme.sh:/acme.sh
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - DEPLOY_DOCKER_CONTAINER_LABEL=sh.acme.autoload.domain=example.com
      - DEPLOY_DOCKER_CONTAINER_KEY_FILE="/etc/nginx/ssl/example.com/key.pem"
      - DEPLOY_DOCKER_CONTAINER_CERT_FILE="/etc/nginx/ssl/example.com/cert.pem"
      - DEPLOY_DOCKER_CONTAINER_CA_FILE="/etc/nginx/ssl/example.com/ca.pem"
      - DEPLOY_DOCKER_CONTAINER_FULLCHAIN_FILE="/etc/nginx/ssl/example.com/full.pem"
      - DEPLOY_DOCKER_CONTAINER_RELOAD_CMD="service nginx force-reload"

修改 `/data/docker_config/nginx/nginx.conf` 啓用 ssl， Configuring HTTPS servers

# HTTPS server

server {
    listen       443 ssl;
    server_name  example.com;

    ssl_certificate      /etc/nginx/ssl/example.com/cert.pem;
    ssl_certificate_key  /etc/nginx/ssl/example.com/key.pem;;

    location / {
        root   html;
        index  index.html index.htm;
    }
}

啓動 `docker-compose`

進入dockerr-compose.yml所在的目錄啓動容器 sudo docker-compose up -d

沒猜錯的話啓動結果應該是nginx啓動失敗，acme.sh啓動成功，啓動失敗無所謂，部署完SSL證書以後會進行一次重啓。

CONTAINER ID        IMAGE                      COMMAND                  CREATED             STATUS                  PORTS                                      NAMES

申請證書

第一步需要獲取你的阿里雲 API Key，既API KEY和API Security，官方推薦使用子賬戶來申請，但是不確定需要賦值哪個權限，總是提示Invalid Domain，用了Root的API Key一次申請通過，看了一下權限列表好像是這個AliyunDNSFullAccess 管理雲解析（DNS）的權限。阿里雲APIKEY管理頁面在這裏：https://ak-console.aliyun.com/#/accesskey

獲取API KEY之後，執行如下命令：

sudo docker exec -e Ali_Key="iAihASlUDxxxxxxx" -e Ali_Secret="FaYpsThfLRbQ99UaHWvvibqxxxxxxx" runAcmesh_example.com --issue --dns dns_ali -d *.example.com

Ali_Key和 Ali_Secret 就是獲取的阿里雲訪問權限的KEY， runAcmesh_example.com是已運行的容器名字，也可以用容器ID來代替， *.example.com 要申請的域名，這個是泛域名，如果不想申請泛域名，只想申請 www.example.com 和 example.com 的話，可以指定多個 -d 參數，例如 -d www.example.com -d example.com -d test.example.com 不過好像每次申請的SSL證書有域名大小限制。

如果順利的話輸出內容如下：

[Sat Jan  9 08:21:03 UTC 2021] And the full chain certs is there:  /acme.sh/*.example.com/fullchain.cer

在docker-compose.yml中已經將/acme.sh目錄link到了/data/docker_config/acme.sh目錄，在該目錄可以看到申請的一套ssl證書。

部署SSL證書

還差最後一步部署SSL證書，執行如下命令：

$ sudo docker exec runAcmesh_example.com --deploy -d *.example.com --deploy-hook docker

輸出如下命令：

[Sat Jan  9 08:22:53 UTC 2021] Container id: 64879a113906f04d0227b8fc26321bc030cd38a2b69d7fe7462c2e7726bxxxxx

[Sat Jan  9 08:22:54 UTC 2021] Copying file from /acme.sh/*.example.com/*.example.com.cer to /etc/nginx/ssl/example.com/cert.pem
[Sat Jan  9 08:22:54 UTC 2021] Copying file from /acme.sh/*.example.com/ca.cer to /etc/nginx/ssl/example.com/ca.pem
[Sat Jan  9 08:22:55 UTC 2021] Copying file from /acme.sh/*.example.com/fullchain.cer to /etc/nginx/ssl/example.com/full.pem
[Sat Jan  9 08:22:55 UTC 2021] Reloading: service nginx force-reload
[Sat Jan  9 08:22:56 UTC 2021] Success

至此部署完成.

docker-compose.yml中的配置項/data/docker_config/nginx/ssl:/etc/nginx/ssl，猜測部署是把SSL文件移動到nginx容器中，但是容器重啓會將文件丟失，所以link到了物理機上面，在執行 docker-compose up 文件是否會自動複製沒有進行驗證，只是多做了一步link。

不出意外的話，用https協議訪問網址應該就沒問題了。
