Try to implement your file-appender with

<pre><code>&lt;configuration&gt;
 ...
 &lt;property name="LOG_PATH" value=/var/app&gt;
 ...
 &lt;appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"&gt; 
 &lt;file&gt;${LOG_PATH}/spring.log&lt;/file&gt;
 ... 
 &lt;/appender&gt;
&lt;/configuration&gt;
</code></pre>

And after this you can run the next command:

<pre><code>docker exec -it containerName cat /var/app/spring.log &gt; $HOME/spring.log
</code></pre>

or make volume with <code>(docker run ... -v "$HOME/app:/var/app")</code>

I am using the following way: in logback.xml:

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
</code></pre>



<pre><code>&lt;property name="LOG_PATH" value="logs"/&gt;
&lt;timestamp key="currentTimestamp" datePattern="yyyy-MM-dd'_'HH"/&gt;

&lt;appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"&gt;
 &lt;encoder&gt;
 &lt;pattern&gt;
 %d{dd-MM-yyyy HH:mm:ss.SSS} %magenta([%thread]) %highlight(%-5level) %logger.%M$%line$ - %msg%n
 &lt;/pattern&gt;
 &lt;/encoder&gt;
&lt;/appender&gt;

&lt;appender name="SAVE-TO-FILE"
 class="ch.qos.logback.core.rolling.RollingFileAppender"&gt;
 &lt;file&gt;${LOG_PATH}/appName.log&lt;/file&gt;
 &lt;encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"&gt;
 &lt;Pattern&gt;
 %d{dd-MM-yyyy HH:mm:ss.SSS} [%thread] %-5level %logger{36}.%M - %msg%n
 &lt;/Pattern&gt;
 &lt;/encoder&gt;

 &lt;rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"&gt;
 &lt;!-- the rollover occurs when the active log file reaches the maximum file size before the end of the time period. --&gt;
 &lt;!-- The rollover period is inferred from the smallest date unit value of fileNamePattern --&gt;
 &lt;!-- each file should be at most [maxFileSize], keep [maxHistory] days worth of history, but at most [totalSizeCap] --&gt;
 &lt;maxFileSize&gt;100MB&lt;/maxFileSize&gt;
 &lt;fileNamePattern&gt;
 ${LOG_PATH}/archived/appName.%d{yyyy-MM-dd}.%i.log
 &lt;/fileNamePattern&gt;
 &lt;maxHistory&gt;30&lt;/maxHistory&gt;
 &lt;totalSizeCap&gt;1GB&lt;/totalSizeCap&gt;
 &lt;/rollingPolicy&gt;
&lt;/appender&gt;


&lt;root level="INFO"&gt;
 &lt;appender-ref ref="STDOUT"/&gt;
 &lt;appender-ref ref="SAVE-TO-FILE"/&gt;
&lt;/root&gt;
</code></pre>



In docker run :

<pre><code>docker run --network name-network --restart=unless-stopped --name name-java-container 
--hostname valueOfHostname -d -p 8080:8080 \
-v /data/nameFolderForLogs:/logs \
imageName
</code></pre>

I have a spring boot java application running inside a docker container. I configured logback in the application. Where i can access the generated logs? The configured path is:

<pre><code>&lt;property name="LOG_PATH" value="logs"/&gt;
</code></pre>

I am currently checking logs using: docker logs containerName --follow 
But this command return the current logs from the last time the application was started. How can i check the rolling logs or archived ones.

Is there a way to create a volume for logback logs?
