hubot-notifier pod fails with java version error in docker container #6929

Open ahmadiq opened 7 years ago

ahmadiq commented 7 years ago

I deployed on a single machine with gofabric8 and minikube. Installing chat-slack, However the hubot-notifier pod keeps restarting with the below exception logged in the container logs. I tried using different versions of hubot-notifier docker image and it seems the error appears on fabric8/hubot-notifier:2.2.300 and later versions.

It looks like the jar expect something newer than java 1.7. I'd offer to make a PR but I cannot for the life of me find the Dockerfile used for building this image.

run the image interactively

mkinsley-MBP-0A2E2:external-dns$ kubectl run -it mktest --image=fabric8/hubot-notifier:2.2.335 --restart=Never -- bash If you don't see a command prompt, try pressing enter.

what version of java is installed?

[root@mktest /]# which java /usr/bin/java [root@mktest /]# java -version java version "1.7.0_85" OpenJDK Runtime Environment (rhel-2.6.1.2.el7_1-x86_64 u85-b01) OpenJDK 64-Bit Server VM (build 24.85-b03, mixed mode)

maybe we just aren't looking hard enough...

[root@mktest /]# find -type f -name java ./var/lib/alternatives/java ./usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85-2.6.1.2.el7_1.x86_64/jre/bin/java ./usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85-2.6.1.2.el7_1.x86_64/bin/java ./usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85-2.6.1.2.el7_1.x86_64/jre-abrt/bin/java [root@mktest /]#
