Spring boot logging how to set logging.file.max-size unlimited

Question

I am working with spring boot application where I am using logback for LOGGING purpose and I want to store my log on log file with unlimited size but default size of logging.file.max-size property is 10MB can anyone help me that what value I need to set on logging.file.max-size to achieve unlimited file size for log file?

I think you should not go for unlimited size. Perhaps it is appropriate to have an unlimited amount of logfiles, but: what do you want to do with logs that are several months old ? — Marged, Sep 18 '18 at 06:07

There is no way to set an unlimited size as such, but there is a workaround
You can set a huge limit for the max size, like this:

logging.file.max-size: 100000GB

Set this in application.yml or application-test.yml
If your machine has more than 100,000 GB of disk space, you can use a higher number ;].

Background:
Spring boot loads this default config file: org/springframework/boot/logging/logback/base.xml
That file includes: org/springframework/boot/logging/logback/file-appender.xml
Which uses SizeAndTimeBasedRollingPolicy

Log files rotate when they reach 10 MB and, as with console output, ERROR-level, WARN-level, and INFO-level messages are logged by default. Size limits can be changed using the logging.file.max-size property. Previously rotated files are archived indefinitely unless the logging.file.max-history property has been set.

More customization you can do for logging, please refer Spring Boot Logging

logging.file.max-size is deprecated, use logging.logback.rollingpolicy.max-file-size instead – Aybek Kokanbekov Nov 23 '21 at 07:47

add below in your logback.xml

<timeBasedFileNamingAndTriggeringPolicy
            class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>5MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
