Im Developing a simple docker file for a spring boot war file.
FROM openjdk:8-jdk-alpine
ARG CONFIG_LOC=/app_config
RUN mkdir $CONFIG_LOC
COPY app_config/* $CONFIG_LOC/
ARG JAR_FILE=target/*.war
COPY ${JAR_FILE} app.war
ENTRYPOINT ["java","-Dspring.config.location=/app_config","-Dspring.profiles.active=docker","-jar","/app.war"]
Some how the argument config location is not are not loading when running the spring application. So the spring application is not running.
Is there a reason to use these as arguments? Usually using something like ARG CONFIG_LOC
means you're passing a value in your build command using --build-arg
. Seems like in this build you should just use hard coded values. When running the application, any argument should be passed as an environment variable using the -e
flag.
