docker-compose

问题 I've found that if I override an image's ENTRYPOINT in a docker-compose service entry, that it ignore variables defined in the environment section but will read them from an env file, e.g. someserver: image: "some-server:latest" restart: always ports: - "8849:8849" environment: javaMemoryLimit: 3056M JAVA_OPTS: "-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=8849 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun

问题 Im working on an application where I have a react frontend and a java spring backend. I have a simple API call where I want to return a new address. I have verified this works by using a separate container to perform a curl command docker container run --rm -it --net multichain-network byrnedo/alpine-curl http://multichain-api:8080/api/blockchain/address/create . This call returns the the expected result. Now I have created my docker environments using docker-compose and they are all up and
