報錯

解決

開啟influxdb

// 挂載/root/tick/influxdb下的influxdb.conf代替預設的容器裡面的/etc/influxdb/influxdb.conf
// 把influxdb的資料挂載到主控端，influxdb的資料預設儲存在/var/lib/influxdb，現在把容器的/var/lib/influxdb資料挂載到主控端的/root/data/metric目錄
docker run -p 8086:8086 --name influxdb -v /root/tick/influxdb:/etc/influxdb -v /root/data/metric:/var/lib/influxdb -d docker.io/influxdb:1.7 
           

開啟telegraf

// 使用/root/tick/telegraf/telegraf.conf代替預設的容器自帶的/etc/telegraf/telegraf.conf
// 使用的是host網絡模式，因為influxdb也安裝在這個機器上
docker run --name telegraf --network host -v /root/tick/telegraf:/etc/telegraf -d docker.io/telegraf:1.11
           

報錯

但是telegraf啟動後，檢視日志報錯了：

把主控端的/var/run/docker.sock挂載到容器

// 把主控端的/var/run/docker.sock挂載到容器
docker run --network host --name telegraf -v /root/tick/telegraf:/etc/telegraf -v /var/run/docker.sock:/var/run/docker.sock -d docker.io/telegraf:1.11
