The code for this issue is here: https://github.com/NathanDotTo/structurizr-onpremises/blob/main/structurizr-onpremises/Dockerfile_service I am using the AppD agent within a Tomcat based web app. The agent directory is copied into the container unaltered from the original zip file: ENV APPDAGENTDIR=AppServerAgent-1.8-23.10.0.35234 ADD $APPDAGENTDIR /$APPDAGENTDIR RUN chown -R root /$APPDAGENTDIR RUN chmod -R a+rwx /$APPDAGENTDIR I start the web app with: ENV CATALINA_OPTS="-Xms512M -Xmx512M -javaagent:/AppServerAgent-1.8-23.10.0.35234/javaagent.jar" I get this error: >>>> MultiTenantAgent Dynamic Service error - could not open Dynamic Service Log /AppServerAgent-1.8-23.10.0.35234/ver23.10.0.35234/logs/8b60cbc478b0/argentoDynamicService_11-27-2023-08.17.53.log Running as user root Cannot write to parent folder /AppServerAgent-1.8-23.10.0.35234/ver23.10.0.35234/logs/8b60cbc478b0 Could NOT get owner for MultiTenantAgent Dynamic Services Folder Likely due to fact that owner (null) is not same user as the runtime user (root) which means you will need to give group write access using this command: find external-services/argentoDynamicService -type d -exec chmod g+w {} Possibly due to lack of permissions or file access to folder: Exists: false, CanRead: false, CanWrite: false Possibly due to lack of permissions or file access to log: Exists: false, CanRead: false, CanWrite: false Possibly due to java.security.Manager set - null Possibly due to missed agent-runtime-dir in Controller-XML and will need the property set to correct this... Call Stack: java.io.FileNotFoundException: /AppServerAgent-1.8-23.10.0.35234/ver23.10.0.35234/logs/8b60cbc478b0/argentoDynamicService_11-27-2023-08.17.53.log (No such file or directory) From within the container I can see that the logs directory is owned by root: cd /AppServerAgent-1.8-23.10.0.35234/ver23.10.0.35234/logs/ root@8b60cbc478b0:/AppServerAgent-1.8-23.10.0.35234/ver23.10.0.35234/logs# ls -la total 16 drwxrwxrwx 1 root root 4096 Nov 27 08:20 . drwxrwxrwx 1 root root 4096 Oct 27 20:45 .. drwxr-x--- 2 root root 4096 Nov 27 08:20 Tomcat@8b60cbc478b0_8005 root@8b60cbc478b0:/AppServerAgent-1.8-23.10.0.35234/ver23.10.0.35234/logs# Since the logs directory is clearly owned by root, I suspect that the error message is simply misleading.  Any suggestions please?
