Docker-compose - facing error while starting container after adding logging option
问题
我们的Docker版本是20.10.21，构建版本是baeda1f。在docker-compose.yml中没有指定日志选项时，它可以正常运行，但是当我们指定日志选项并启动docker-compose时，它会抛出错误“ERROR: for
这是docker-compose.yml中该服务的条目 -
logging:
driver: "json-file"
options:
max-file: 5
max-size: 10m
请告诉我我们的配置可能有什么问题。感谢您的帮助。
英文:
We have Docker version 20.10.21, build baeda1f. It is running fine without logging options in docker-compose.yml but when we specify the logging options and then start docker-compose, it throws an error
"ERROR: for <servicename> Cannot create container for service <servicename>: json: cannot unmarshal number into Go struct field LogConfig.HostConfig.LogConfig.Config of type string"
This is the entry in docker-compose.yml under that service -
logging:
driver: "json-file"
options:
max-file: 5
max-size: 10m
Please let me know what might be wrong with our configuration. Appreciate your help.

原来我必须将 max-file 指定为字符串。四年前已经有人提出了这个问题，并自己找到了答案。

希望对某人有所帮助。

Turned out that I had to specify max-file as string. It was already asked by someone 4 years ago, who found the answer himself.
