My container has a correct date and timezone. But my tomcat is getting one hour more than I configured. How to fix wrong time in tomcat 9 container?

523 Views Asked by At

I am trying to make it run setenv.sh to load some JAVA_OPTS but is it not loading nothing. My Tomcat start a .war files using springboot for start my application. The problem here is that it is not loading correct timezone on java and it is not loading JMX and Prometheus exporters.

Here is my docker file.

How can I tell it to load correctly my setenv.sh file? Is this something on spring config lacking configurations?

I tried a lot of things to start it using my VARs even putting then into catalina.sh and I have no positive results.

I need to load those apps and load prometheus and JMX and put it to work with correct time. All my VARS are working on a real installed tomcat.

What I am doing wrong, please?

I would like to run my tomcat 9 servers with java loading a correct timezone. It is loading one hour more than current time. And I need to put JMX to be acessed outside my container. And I need to export this container status to Prometheus.

To set environment variables in a Docker container, you can use the ENV instruction in your Dockerfile, like you have done. You can also set environment variables when you start the container using the -e flag with docker run.

For example: docker run -e JAVA_OPTS="-Duser.timezone=UTC" my_image

To load

The environment use source command the docker file for example COPY setenv.sh /usr/local/tomcat/bin/setenv.sh RUN chmod +x /usr/local/tomcat/bin/setenv.sh

CMD ["catalina.sh", "run"] ENTRYPOINT ["/bin/bash", "-c", "source /usr/local/tomcat/bin/setenv.sh && exec /usr/local/tomcat/bin/catalina.sh run"] . $CATALINA_HOME/bin/setenv.sh

Rule change in Brazil time zone

Your problem seems to be that Java is reporting the same time, but in daylight saving time (I believe BRST=Brasilia Summer Time, which is UTC-2).

According to Wikipedia, Brazil stopped using daylight saving time in 2019. According to this page the change was included in Java 1.8.0_231, while you’re on Java 1.8.0_202.

Updating to Java 1.8.0_231 or later, if you can, ought to fix the inconsistency.
