目的

目标是将家中小型主机上运行的服务容器化，并通过内网穿透使其可以从公网访问。

技术选型

halo
Halo [ˈheɪloʊ]，强大易用的开源建站工具。是时候给hexo加个后台了。
apisix
Apache APISIX 是一个高性能、可扩展的开源 API 网关。这里用来管理和控制容器化后的服务。
cloudflare tunnel
cloudflare的内网穿透工具，免费！

apisix

参考 apisix-docker

这里去掉了grafana和普罗米修斯
将apisix的默认9080映射到宿主机的80端口，顺眼
给network改了个名字，方便其他的docker加入

增加.env，规范network的生成

COMPOSE_PROJECT_NAME=b1ank

➜  app docker network ls     
  NETWORK ID     NAME                DRIVER    SCOPE
  40fe9edd7249   b1ank_home          bridge    local

注意修改默认的admin_key和用户名密码

halo

参考官方文档

先改掉默认的数据库密码
修改halo.external-url
注释掉mysql映射出来的3306，因为不需要外部连接，容器间互相本身是连通的

version: "3"

services:
  halo:
    image: halohub/halo:2.10
    container_name: halo
    restart: on-failure:3
    depends_on:
      halodb:

    command:
      - --spring.r2dbc.url=r2dbc:pool:mysql://halodb:3306/halo
      - --spring.r2dbc.username=root
      # MySQL 的密码，请保证与下方 MYSQL_ROOT_PASSWORD 的变量值一致。
      - --spring.r2dbc.password=changeme
      - --spring.sql.init.platform=mysql
      # 外部访问地址，请根据实际需要修改
      - --halo.external-url=http://192.168.0.114:8080/

  halodb:
    image: mysql:8.1.0
    container_name: halodb
    restart: on-failure:3
    networks:
      halo_network:

      - --explicit_defaults_for_timestamp=true
    volumes:
      - ./mysql:/var/lib/mysql
      - ./mysqlBackup:/data/mysqlBackup
    #ports:

    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-h", "127.0.0.1", "--silent"]
      interval: 3s
      retries: 5
      start_period: 30s
    environment:
      # 请修改此密码，并对应修改上方 Halo 服务的 SPRING_R2DBC_PASSWORD 变量值

      - MYSQL_DATABASE=halo

Cloudflare Tunnel

创建tunnel参考CloudFlare Tunnel 免费内网穿透的简明教程

设置付款方式的时候直接关掉页面重新进似乎可以绕过
将此处的token保存好，后面要用

容器化参考container-cloudflare-tunnel

改成从远程仓库拉，不自己build了
network连的apisix的，取消了原来的host，收敛暴露面
```
networks:
b1ank_home:
  external: true
```
token在.env里面配置

version: '3'

# service description
services:
  # cloudflare tunnel
  cloudflare-tunnel:
    image: cloudflare/cloudflared
    #build:
    #  context: ./src
    #  dockerfile: ./Dockerfile
    container_name: cloudflare-tunnel
    hostname: cloudflare-tunnel
    restart: unless-stopped
    networks:
      b1ank_home:
    command: tunnel run
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ./config/hosts:/etc/hosts
    environment:
      - "TUNNEL_TOKEN=${CLOUDFLARE_TUNNEL_TOKEN}"
    labels:
      # enbale watchtower updates
      - "com.centurylinklabs.watchtower.enable=true"

networks:
  b1ank_home:
    external: true

服务配置

配置上游
配置路由，并且启用插件配置如下，目的是限制外部访问管理后台

{
  "_meta": {
    "disable": false
  },
  "block_rules": [
    "/console"
  ],
  "rejected_code": 404,
  "rejected_msg": "404 page not found"
}

cloudflare处配置服务，统一配apisix，由apisix来做反向代理
