现象

同事联系说部署在虚拟机里面的用docker启动xxl-job的服务不好使了，需要解决一下，我就登陆虚拟机检查，发现根目录满了，就一层一层的找，发现是<container_id>-json.log超级大，追空之后重启服务就好使了。
/var/lib/docker/containers/<container_id>/<container_id>-json.log

一、查找源头

[root@xxl-job docker]# du -sh *
88K	buildkit
16G	containers
4.0K	engine-id
444K	image
48K	network
470M	overlay2
0	plugins
0	runtimes
0	swarm
0	tmp
0	tmp-old
24K	volumes
[root@xxl-job docker]# cd containers/
[root@xxl-job containers]# ls
98d41152c3fccd36f21445751249927ade16d8c56b2adedaa2733b3c210a7c68
[root@xxl-job containers]# cd 98d41152c3fccd36f21445751249927ade16d8c56b2adedaa2733b3c210a7c68/
[root@xxl-job 98d41152c3fccd36f21445751249927ade16d8c56b2adedaa2733b3c210a7c68]# du -sh *
16G	98d41152c3fccd36f21445751249927ade16d8c56b2adedaa2733b3c210a7c68-json.log
0	checkpoints
4.0K	config.v2.json
4.0K	hostconfig.json
4.0K	hostname
4.0K	hosts
0	mounts
4.0K	resolv.conf
4.0K	resolv.conf.hash

二、分析

tail -f 看了一下这个文件，感觉就是服务日志没有转到日志目录下导致没有被日志的定时清理机制管理上。所以越来越大。

[root@xxl-job 98d41152c3fccd36f21445751249927ade16d8c56b2adedaa2733b3c210a7c68]# tail -f 98d41152c3fccd36f21445751249927ade16d8c56b2adedaa2733b3c210a7c68-json.log
