override context path for manager application
Hi all:
The context path of the Tomcat manager application is "/manager" by default [0].
I am trying to change this context path from the default using an override configuration.
I am doing the typical creation of a container using makebase.sh and setting CATALINA_BASE before starting it.
To enable the manager application on these containers, I create a file $CATALINA_BASE/conf/[engine]/[host]/manager.xml with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/manager" docBase="${catalina.home}/webapps/manager" antiResourceLocking="false" privileged="true">
</Context>
In catalina.out I see the following log output:
04-Dec-2019 12:54:07.063 INFO [main] org.apache.catalina.startup.HostConfig.deployDescriptor Deployment of deployment descriptor [/home/tomcat/servers/dev9/conf/Catalina/localhost/manager.xml] has finished in [200] ms
The manager application is mapped into my container at "/manager" and is functional in every way.
But if I use a manager.xml to map the manager application into my container with an offset path like the following:
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/dev9/manager" docBase="${catalina.home}/webapps/manager" antiResourceLocking="false" privileged="true">
</Context>
I see the following log output in catalina.out instead:
04-Dec-2019 13:08:42.089 WARNING [main] org.apache.catalina.startup.HostConfig.deployDescriptor The path attribute with value [/dev9/manager] in deployment descriptor [/home/tomcat/servers/dev9/conf/Catalina/localhost/manager.xml] has been ignored
04-Dec-2019 13:08:42.333 INFO [main] org.apache.catalina.startup.HostConfig.deployDescriptor Deployment of deployment descriptor [/home/tomcat/servers/dev9/conf/Catalina/dotancappdev1/manager.xml] has finished in [245] ms
Why is my override path of "/dev9/manager" ignored?
Can the context path of the manager and host-manager applications be changed?
The documentation implies that "/manager" is only a default, and it seems I should be able to change it but have had no success.
My environment is Tomcat 9.0.29 with OpenJDK 1.8.0_232 on Debian Linux.
Thanks,
Jason

Konstantin:
Thank you for your point #1 below!
When I remove "path" attribute entirely from my override configuration
and save it as "dev9#manager.xml" then I get exactly the result I want.
However, I did not need to move the manager application from the
"${catalina.home}/webapps" directory as in your point #2.
I am running my container from a completely separate directory structure
with $CATALINA_BASE != $CATALINA_HOME and $CATALINA_BASE/webapps/ does
NOT contain the manager application.
I think your point #2 would be correct if I simply decompressed the
Tomcat distribution and ran it with $CATALINA_BASE == $CATALINA_HOME and
I was just adding a file to
$CATALINA_HOME/conf/[engine]/[host]/dev9#manager.xml in an attempt to
override the context path.
Thanks again for your help,
Jason

This should not be necessary. The OP is using a split CATALINA_BASE
and so CATALINA_HOME/webapps/manager will not be auto-deployed.

The usage of "path" attribute above is invalid. It must never be used
in a context xml file and it is ignored there,
because the path is derived from the name of the file.
See
http://tomcat.apache.org/tomcat-9.0-doc/config/context.html
If you want to rename the application, you must do the following:
1) first, rename the file itself, e.g. to
$CATALINA_BASE/conf/[engine]/[host]/dev9#manager.xml
$CATALINA_BASE/conf/[engine]/[host]/mymanager.xml
etc.
2) second, you must move the manager application from
"${catalina.home}/webapps/" to some other directory.
The applications in "webapps/" directory are auto-deployed when Tomcat
starts. If you keep the manager app there, it will be deployed twice,
with the new and with the old name.
