Installation failed in Docker + Kubernetes

Hi there,

In the environment of Kubernetes, we implemented the following procedure.

https://www.dynatrace.com/support/help/cloud-platf...

Since Java is used, we made the following settings.

Dockerfile FROM openjdk:8-jdk-alpineCOPY ./app.jar app.jar
ARG DT_API_URL="https://<environmentID>.live.dynatrace.com/api"
ARG DT_API_TOKEN="<token>"
ARG DT_ONEAGENT_OPTIONS="flavor=default&include=java"
ENV DT_HOME="/opt/dynatrace/oneagent" RUN mkdir -p "$DT_HOME" && \ wget -O "$DT_HOME/oneagent.zip" "$DT_API_URL/v1/deployment/installer/agent/unix/paas/latest?Api-Token=$DT_API_TOKEN&$DT_ONEAGENT_OPTIONS" && \ unzip -d "$DT_HOME" "$DT_HOME/oneagent.zip" && \ rm "$DT_HOME/oneagent.zip" ENTRYPOINT [ "/opt/dynatrace/oneagent/dynatrace-agent64.sh" ]
CMD [ "java", "-jar", "app.jar" ]

*EnviromentID and tokens hide values

However, it seems that the setting is not done well, and data could not be acquired.

Java injection seems to have failed. Please tell me how to improve and what to check.

Hi - It seems your app is based on an alpine image. Please follow the instruction in https://www.dynatrace.com/support/help/cloud-platf... for "What if my Docker image is based on Alpine Linux?"
