docker - docker 巨大的log文件： prune daemon.json

更新：找到根源了：服务器的空间不够
docker system prune
docker system prune -a --volumes
使用 du -a / | sort -n -r | head -n 2000 > /tmp/largest_nls
发现，有一个超级巨大的log: 325511780 /var/lib/docker/containers/09d44ba32c76248178d852ac5c2d5c32f7e325160420ade351f6260434923767/09d44ba32c76248178d852ac5c2d5c32f7e325160420ade351f6260434923767-json.log
325G.
解决办法：
vim /etc/docker/daemon.json
{
"log-driver": "json-file",
"log-opts": {
"max-size": "100m", // 单个日志文件最大100MB
"max-file": "3" // 最多保留3个日志文件
}
}
然后重启docker：
systemctl daemon-reload && systemctl restart docker
也可以先手动运行这个命令，先把空间腾出来：
truncate -s 0 /var/lib/docker/containers/09d44ba32c76248178d852ac5c2d5c32f7e325160420ade351f6260434923767/09d44ba32c76248178d852ac5c2d5c32f7e325160420ade351f6260434923767-json.log

今天遇到这个问题，怎么样都搞不定，最后用 docker system prune 搞定了。
