Geoserver docker 2.28.x broken

pols · November 5, 2025, 12:44pm

I dont know if this issue is on the right place:
Since last week the geoserver docker is broken, i’m using docker.osgeo.org/geoserver:2.28.0
log:
3-Nov-2025 11:41:04.083 SEVERE [main] org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file

03-Nov-2025 11:41:04.087 SEVERE [main] org.apache.catalina.core.StandardContext.startInternal Context [/geoserver] startup failed due to previous errors

version 2.28.0 is still working, anyone an idea?
I dont see any errors in the docker logs.

You should really be on the GeoServer-Users topic (I can’t work out how to forward a message though),

Anyway, you need to look at the geoserver log file to see what is failing rather than the docker logs.

you cant read the geoserver logs, because the server wont start, so you cant reach the log files.

So log in and use an editor or pager to view the file on disk.

I was able to move the topic to the correct category.

In October I worked on docker as part of the code freezes for GeoServer 3. The work I did was to make docker choose tomcat 9 or tomcat 11 base image based on the version of GeoServer being published. The 2.28.0 release was made previously so it should not be affected …

.. so yes if you have more details, perhaps exactly what you used to start up with, it would be good to know what is going on.

For GeoServer 3.x nightly builds testing docker and the install instructions is something to be done.

We also have the new idea of “pending” community modules which will be published alongside GeoServer as they seek wider resources/funding/testing/deployments to be made official extensions.

I just run a clean docker image like this:

docker run -d --name geoserver-test -p 8080:8080 docker.osgeo.org/geoserver:2.28.x

and it ends in an error, tomcat is up and running and this are the logs from docker:

I think I see the problem:

*06-Nov-2025 08:01:21.640 INFO \[main\] org.apache.catalina.startup.VersionLoggerListener.log JVM Version:           11.0.28+6*

2.28.x is Java 17 minimum now, the release.sh script should be selecting a different base image.

      if [[ "$VERSION" == "3."* ]]; then
         GEOSERVER_BASE_IMAGE=tomcat:11.0-jdk21-temurin-noble
      else
         GEOSERVER_BASE_IMAGE=tomcat:9.0-jdk11-temurin-noble
      fi

We need some logic for:

3.0.x - tomcat 11 jdk17
2.28.x - tomcat 9 jdk17
other - tomcat 9 jdk11

Any takers?

I did a simple fix, as JDK17 can be used for active branches of GeoServer.

I note however that many recent docker builds are failing:

+ wget -c -q -O /tmp/geoserver.zip https://build.geoserver.org/geoserver/main/geoserver-main-latest-war.zip
[0me[91m+ unzip geoserver.zip geoserver.war -d /tmp/
[0mArchive:  geoserver.zip
[91merror [geoserver.zip]:  start of central directory not found;
  zipfile corrupt.
  (please check that you have transferred or created the zipfile in the
  appropriate BINARY mode and that you have compiled UnZip properly)

When I go to these URLs directly, it is fine. I expect I am not good at the wget syntax.

Because we build a normal and a gdal image an attempt is made to avoid downloading zip twice.

I have managed to get the docker 2.28.x to build again (clearing the download prior to each run).

It should now use tomcat 9 and JDK 17 and thus start up - Please give it a go and let me know if works!

Yes i downloaded the latest version and it is solved, thank you!
