Pass multiple system parameters thorugh docker-compose-->dockerfile--> springboot application housed in docker container - spring-boot

Question

Below is the content of my docker-compose.yml file:
eureka-server:
image: controlsplm/eureka-server
environment:
HOST_IP: X.X.X.X
ACTIVE_PROFILE=docker-development-cloud
ports:
- "8761:8761"
restart: always
And below is the content of my docker file:
FROM java:8
VOLUME /tmp
ADD eureka-server-0.1.0-SNAPSHOT.jar app.jar
EXPOSE 8761
RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Denvironment=$HOST_IP","-Dspring.profiles.active=$ACTIVE_PROFILE","-jar","/app.jar"]
But when i run the docker container using compose, HOST_IP is picked up but not ACTIVE_PROFILE. AM i missing anything here? Kindly help...

Answer 1

Indeed, if you have Spring properties
my.spring.property.one=green
my.spring.property.two=blue
You can include them as follows in the docker-compose.yml:
environment:
- my_spring_property_one=green
- my_spring_property_two=blue
worked for my with
Spring Boot v1.5.10.RELEASE
Spring v4.3.14.RELEASE
docker version '3.6'

I see two problems:
the format of the ACTIVE_PROFILE is wrong, it would be ACTIVE_PROFILE: docker-development-cloud as mentioned by #andreas-jägle in the comments
The entrypoint uses json array notation, which means the command is exec'ed directly without a shell. The shell (usually bash) is what replaced the variables with their values, so you need to run in a shell to use those variables. You can either use the string form of ENTRYPOINT, or use:
ENTRYPOINT ["bash", "-c" ,"java - Dspring.profiles.active=$ACTIVE_PROFILE ..."]

I resolved the issue by adding below lines to my docker-compose.yml file:
eureka-server:
image: controlsplm/eureka-server:latest
environment:
HOST_IP: X.X.X.X
SPRING_PROFILES_ACTIVE: docker-development-cloud
ports:
- "8761:8761"
restart: always
and below lines in dockerfile:
FROM java:8
VOLUME /tmp
ADD eureka-server-0.1.0-SNAPSHOT.jar app.jar
EXPOSE 8761
RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Denvironment=$HOST_IP","-jar","/app.jar"]
