Question

我正在尝试检查已停止的Docker容器的日志，但是当我执行docker logs <container-id>时，会收到如下响应：

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

我尝试检查默认的日志记录驱动程序，但找不到。但是，我尝试通过在/ etc / docker文件夹中创建一个daemon.json文件来与Docker中的其他驱动程序一起玩以进行日志记录。我使用service docker restart重新启动了docker服务。这也没有帮助我。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？

有人可以帮我吗？

很久以前问过，但我也搜索过...

您可以使用以下方法检查默认的日志记录驱动程序

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

或者，

ars@ars-thinkpad ~ $ docker info --format '{{.LoggingDriver}}'
json-file

要获取现有容器的驱动程序，

ars@ars-thinkpad ~ $ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                     NAMES

ars@ars-thinkpad ~ $ docker inspect a48314f1c163 | grep -i -C 5 log
        },

        "ResolvConfPath": "/var/lib/docker/containers/a48314f1c16356f3cf534b273ea3871a26882d1466979c48e38611d8106594df/resolv.conf",
        "HostnamePath": "/var/lib/docker/containers/a48314f1c16356f3cf534b273ea3871a26882d1466979c48e38611d8106594df/hostname",

        "Name": "/node3",
        "RestartCount": 0,
        "Driver": "overlay2",
        "Platform": "linux",

        "AppArmorProfile": "unconfined",

        "HostConfig": {
            "Binds": [],
            "ContainerIDFile": "",
            "LogConfig": {

            },
            "NetworkMode": "tests_mtm_bridge",
            "PortBindings": {

对于我来说，它是json-file，具有实际的日志文件路径/var/lib/docker/containers/a48314f1c16356f3cf534b273ea3871a26882d1466979c48e38611d8106594df/a48314f1c16356f3cf534b273ea3871a26882d1466979c48e38611d8106594df-json.log。
