Different behaviour on 2 containers of same tomcat image run on 2 Debian servers
Metabaron1 opened this issue · 2 comments
When I run docker tomcat manager on 2 Debian servers I have these 2 displays:
- Tomcat1: https://i.stack.imgur.com/kucJQ.png
- Tomcat2: https://i.stack.imgur.com/ygOCh.png
Tomcat status memory pools are listed with different names as "PS < memory pool>" in Tomcat 1 and only "< memory pool >" in Tomcat 2 (like "PS Eden Space" vs "Eden Space").
Both container are run the same way :
# docker run --name tomcat-test -it -p 8083:8080 -v /tmp/tomcat-users.xml:/usr/local/tomcat/conf/tomcat-users.xml -v /tmp/context.xml:/tmp/context.xml tomcat:8.5-jdk8-openjdk /bin/bash -c "mv /usr/local/tomcat/webapps /usr/local/tomcat/webapps2; mv /usr/local/tomcat/webapps.dist /usr/local/tomcat/webapps; cp /tmp/context.xml /usr/local/tomcat/webapps/manager/META-INF/context.xml; catalina.sh run"
with same param xml files:
# cat /tmp/context.xml
<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>
# cat /tmp/tomcat-users.xml
<tomcat-users>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user username="tomcat" password="s3cret" roles="manager-gui,manager-script"/>
</tomcat-users>
Both server are the same versions:
# cat /etc/debian_version
9.13
# docker version
Client: Docker Engine - Community
Version: 19.03.15
Any idea why there is such difference? Shouldn't 2 containers running the same image have the sctrictly same behaviour? It's a small difference but I'm wondering if there is such difference, maybe there are other I don't see...
Unfortunately, these sorts of questions/requests would be more appropriately posted to a dedicated support forum, such as the Docker Community Forums, the Docker Community Slack, or Stack Overflow.
oh ok, sorry
