如何获取relay中继服务器的列表呢
参考项目 https://github.com/dragonfly-club/dragon-relay
这个项目呢 是把列表生成自定义的html页面,不够灵活,所以我改了一下
用以生成json数据
我原本的设想是通过dockerfile重新构建一个docker镜像,但是一想又嫌麻烦,所以只好通过曲线救国了///
使用方法

bash脚本
update-list.sh的内容
#!/bin/sh
if [ ! -f /tmp/setup_done ]; then #如果存在安装缓存则跳过,重启容器会重新安装依赖
apk add python3 py3-pip py3-requests #安装python
apk add tzdata #修正时区
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
echo "Asia/Shanghai" > /etc/timezone
touch /tmp/setup_done
fi
cd /relay/
./gen-member-list.py || exit 1;
exit 0;
修改Dockercompose.yaml
这一步就是映射本地脚本到docker容器中
services:
redis:
restart: always
image: redis:alpine
healthcheck:
test: ["CMD", "redis-cli", "ping"]
volumes:
- "./redisdata:/data"
- "./relay:/relay"
worker:
container_name: worker
build: .
image: yukimochi/activity-relay
working_dir: /var/lib/relay
restart: always
init: true
command: relay worker
volumes:
- "./actor.pem:/var/lib/relay/actor.pem"
- "./config.yml:/var/lib/relay/config.yml"
depends_on:
- redis
server:
container_name: relay
build: .
image: yukimochi/activity-relay
working_dir: /var/lib/relay
restart: always
init: true
ports:
- "8080:8080"
command: relay server
volumes:
- "./actor.pem:/var/lib/relay/actor.pem"
- "./config.yml:/var/lib/relay/config.yml"
depends_on:
- redis
然后把上面两个脚本都丢进relay的文件夹
定时任务
使用宝塔或者系统的计划任务
activity-relay-redis-1为redis的容器名,执行bash
docker exec activity-relay-redis-1 /bin/sh /relay/update-list.sh
