认知升维: 道、法、术、器、势 一: 配置docker日志文件
通过/etc/docker/daemon.json配置Docker的log-driver参数遇到了Docker无法启动的错误。 配置信息如下
[rootwww ~]# cat /etc/docker/daemon.json { registry-mirrors: [ https://d8b3zdiw.mirror.aliyuncs.com, https://reg-mirror.qiniu.com/, https://hub-mirror.c.163.com/, https://docker.mirrors.ustc.edu.cn/ ], log-driver: json-file, log-opts: { max-size: 50m, max-file: 5 } }
查看日志 journalctl -amu docker
错误信息 dockerd-current[3335]: unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file: graph: (from flag: /data/docker 8月 18 12:02:09 www.yhchange.com systemd[1]: docker.service: main process exited, codeexited, status1/FAILURE 8月 18 12:02:09 www.yhchange.com systemd[1]: Failed to start Docker Application Container Engine. 8月 18 12:02:09 www.yhchange.com systemd[1]: Unit docker.service entered failed state. 8月 18 12:02:09 www.yhchange.com systemd[1]: docker.service failed. 8月 18 12:05:49 www.yhchange.com systemd[1]: Starting Docker Application Container Engine... 8月 18 12:05:49 www.yhchange.com dockerd-current[3446]: unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives dont match any configuration option: data-root 8月 18 12:05:49 www.yhchange.com systemd[1]: docker.service: main process exited, codeexited, status1/FAILURE 8月 18 12:05:49 www.yhchange.com systemd[1]: Failed to start Docker Application Container Engine. 8月 18 12:05:49 www.yhchange.com systemd[1]: Unit docker.service entered failed state. 8月 18 12:05:49 www.yhchange.com systemd[1]: docker.service failed. 这个含义应该是Docker启动的时候传入了命令行参数同时也指定了配置文件两个配置发生了冲突。那么就查看一下Docker服务启动文件。 二 可以看到启动的时候会加载EnvironmentFile-/etc/sysconfig/docker 配置文件
