---------------------------------------------
Hi [~rgoers] , please find below the full XML configuration for my use case.
${logs_dir} is resolved as ${env:LOGS_DIRECTORY} instead of the actual
environment variable value.
{code:java}
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Properties>
<Property name="logs_dir">$${env:LOGS_DIRECTORY}</Property>
</Properties>
<Appenders>
<Routing name="Routing">
<Routes pattern="$${ctx:logFile}">
<!-- This route is chosen if ThreadContext has no value for key
logFile. -->
<Route key="$${ctx:logFile}">
<RollingFile name="Rolling-application"
fileName="${logs_dir}/application.log"
filePattern="${logs_dir}/${date:yyyy-MM}/default-%d{yyyy-MM-dd}-%i.log.gz">
<JSONLayout compact="true" eventEol="true"

<Policies>
<SizeBasedTriggeringPolicy size="10 MB"/>
</Policies>
</RollingFile>
</Route>
<!-- This route is chosen if ThreadContext has a value for
logFile. The value dynamically determines the name of the log file. -->
<Route>
<RollingFile name="Rolling-${ctx:logFile}"
