基于prometheus的自动发现主机监控

准备工作
需要部署一个consul ,创建一个token用于docker-compose和prometheus 同步数据

#启动命令
docker run -d --restart=always --net=host -v /data/prom/consulmanager/consul:/consul --name consul-prometheus consul:1.12.2 agent -config-dir=/consul/config
#创建consul.hcl配置文件
mkdir -p /data/prom/consulmanager/consul/config
cat >/data/prom/consulmanager/consul/config/consul.hcl <<EOF
advertise_addr = "10.x.x.x" #host内网地址
data_dir = "/consul"
client_addr = "0.0.0.0"
ui_config = {
  enabled = true
}
server = true
bootstrap = true
acl = {
  enabled = true
  default_policy = "deny"
  enable_token_persistence = true
}
EOF
#执行bootstrap获取token并配置下面配置文件中
docker run -it consul-prometheus consul acl bootstrap

启动程序docker-compose文件

 cat > docker-compose.yml << EOF 
version: "3.2"
services:
  flask-consul:
    image: registry.cn-shenzhen.aliyuncs.com/starsl/flask-consul:latest
    container_name: flask-consul
    hostname: flask-consul
    restart: always
    volumes:
      - /usr/share/zoneinfo/PRC:/etc/localtime
    environment:
      consul_token: xxx #上面consul的token
      consul_url: http://10.X.X.X:8500/v1
      admin_passwd: asdsadxx #自己定义控制台密码
  nginx-consul:
    image: registry.cn-shenzhen.aliyuncs.com/starsl/nginx-consul:latest
    container_name: nginx-consul
    hostname: nginx-consul
    restart: always
    ports:
      - "1026:1026"
    volumes:
      - /usr/share/zoneinfo/PRC:/etc/localtime
EOF
docker-compose up -d
