spring Logback error coming when starting spring application

Question

Below logback error is coming when starting the spring application which is deployed in Kubernetes.

2022-04-20 13:47:25.928 ERROR 1 --- [ main] o.s.boot.SpringApplication : Application run failed

Logback-spring configuration:-

        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">

            <maxFileSize>1GB</maxFileSize>
            <totalSizeCap>10GB</totalSizeCap>
            <!-- keep 30 days worth of history -->
            <maxHistory>30</maxHistory>
        </rollingPolicy>
    </appender>

Any idea to overcome this error will be helpful as it stops the main application.

Answer 1

You have a maximum filesize of 1GB and specify gzip compression. Depending on your resource configuration in the pod this can lead to quite a long time for performing the compression.

You can either increase the resources or, probably better, reduce the max file size to 100mb.
