Base image to execute JVM applications focused on Spring Boot applications. 8-jre is based on openjdk:8-jre-alpine 8-jre-zulu is based on azul/zulu-openjdk-alpine:8u252-jre 11-jre-openj9 is based on adoptopenjdk/openjdk11-openj9:alpine-jre 11-alpine-jre-openj9 is based on adoptopenjdk/openjdk11-openj9:alpine-jre with a fixed base image to avoid latest tag pitfalls. Used for jib builds to avoid fat jars and entrypoint.sh
This image adds an entrypoint.sh that allows the execution of java applications as user java:java and PID 1.
Example of a Dockerfile using this base image:
FROM image:tag
COPY yourapp.jar .
ENTRYPOINT ["./entrypoint.sh", "yourapp.jar"]
The following environment variables can be set to tune java execution.
e.g., --java_agent:/etc/agent/newrelic.jar (loaded as a volume)
e.g., --Xmx32m -Xss256k
