The official Apache Tomcat Docker Images don´t come with the Manager Gui enabled by default. To enable them you can use the following steps. You could either clone this repository and go straight to step 6. Or you follow the steps, which I recommend. This should hopefully work in future versions
- Make directory for local files, set absolute path for docker commands
mkdir config
ABS_PATH=`pwd`
- Run image initally
docker run -p8888:8080 --name tomkat \
tomcat:9.0.30-jdk11-openjdk
- Get User File
docker cp tomkat:/usr/local/tomcat/conf/tomcat-users.xml $ABS_PATH/config/tomcat-users.xml
- Edit user File
edit file, add user
vi config/tomcat-users.xml
<role rolename="manager-gui"/>
<user username="tomkat" password="change-me" roles="manager-gui"/>
- Get original webapps to replace the currently empty webapps directory in docker container
docker cp tomkat:/usr/local/tomcat/webapps.dist $ABS_PATH/config/webapps
- Edit access valve for manager gui
vi config/webapps/manager/META-INF/context.xml
Place comments around the valve directive like this
<Context antiResourceLocking="false" privileged="true" >
<!--
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
<Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
-->
</Context>
- For restarting the container you might want to use:
docker stop tomkat && docker rm tomkat
- Use local files in your docker image
docker run -p8888:8080 --name tomkat \
-v $ABS_PATH/config/tomcat-users.xml:/usr/local/tomcat/conf/tomcat-users.xml \
-v $ABS_PATH/config/webapps:/usr/local/tomcat/webapps \
tomcat:9.0.30-jdk11-openjdk
- The Manager should work now with a password prompt at http://localhost:8888/manager
