如何检查docker中当前/默认的日志驱动程序？

Question

我正在尝试检查已停止的 docker 容器的日志，但是当我这样做时，docker logs <container-id>我得到如下响应：

Error response from daemon: configured logging driver does not support reading

我尝试检查默认日志记录驱动程序，但找不到。daemon.json但是，我尝试通过在 /etc/docker 文件夹中创建文件来使用 docker 中的其他一些驱动程序进行日志记录。我使用 重新启动了 docker 服务service docker restart。这对我也没有帮助。这里的主要问题是I am still not able to check which driver is the system using currently and how to I get around that problem？

有人可以帮我解决这个问题吗？

很久以前就问过，不过我也搜过……

您可以使用以下命令检查默认日志记录驱动程序

\n

ars@ars-thinkpad ~ $ docker system info | grep -i log\nLogging Driver: json-file\n Log: awslogs fluentd gcplogs gelf journald json-file logentries splunk syslog\nWARNING: No swap limit support\n\n

\n

或者，

\n

ars@ars-thinkpad ~ $ docker info --format \'{{.LoggingDriver}}\'\njson-file\n

\n

要获取现有容器的驱动程序，

\n

json-file在我的例子中，实际的日志文件路径也是如此/var/lib/docker/containers/a48314f1c16356f3cf534b273ea3871a26882d1466979c48e38611d8106594df/a48314f1c16356f3cf534b273ea3871a26882d1466979c48e38611d8106594df-json.log。
