[Walter Xavier Bermudez Tamayo]

Hi! I want add a instroscope agent on a application running on a container, the application runs with the following " FROM" in the Dockerfile

 

FROM openjdk:8-jre-alpine

 

Next, When a I Tried to add a java agent and start the container the following error appears and the application does not start

 

[ec2-user@ip-172-31-42-230 docker-apm]$ docker logs docker-apm

Then If I change the "from" to openjdk:8 the application start correctly and the agent start sending metrics.

 

Any idea how can I add the javaagent?

 

This is the .Dockerfile

 

 

FROM openjdk:8-jre-alpine    ####NOT WORK
FROM openjdk:8               #### WORKS FINE
ADD docker-spring-boot.jar docker-spring-boot.jar
EXPOSE 8080
ADD wily wily
RUN apt-get update && apt-get install telnet
#RUN chmod -R o+x wily
#RUN chmod 777 /wily 
WORKDIR /wily
ENV JAVA_OPTS='-javaagent:Agent.jar -Dcom.wily.introscope.agentProfile=core/config/IntroscopeAgent.profile'
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /docker-spring-boot.jar" ]
#ENTRYPOINT [ "sh", "-c", "java -Djava.security.egd=file:/dev/./urandom -jar /docker-spring-boot.jar" ]

alpine JVM is not supported, there is a certification request DE393918 to have Alphine Linux supported.

 

For now use the openjdk:8

Thanks Sergio, is there any subscription alert for that Development Case?

[Sergio Morales Correa]

Hi Walter,

 

I am afraid it is not possible. It seems adding this support requires code changes so my suggestion for you is to open a support case and for the engineer to link your case with the above DE.  This will help Product management and Development prioritize this request, make sure to include the priority and business impact.

 

As far I can see, this support has already been classified as a Enhancement, that means to be fixed in a future release, there is no ETA.

 

I hope this helps,

Regards,

Sergio
