两个容器之间的Docker通信与Java

我没有在任何帖子上找到答案.

我在容器上使用带有PHP项目的容器,该容器工作正常.我想链接在另一个容器上启动的Java.

我使用“java：8”图像配置如下：

engine:
    build: ./docker/engine/
    volumes:
        - ".:/home/docker:rw"
        - "./docker/engine/php.ini:/usr/local/etc/php/conf.d/custom.ini:ro"
    links:
        - "db:db"
        - "java:java"
    working_dir: "/home/docker"
java:
    image: java:8
    tty: true
    ports:
        - "999:999"

在我的docker PHP容器(调用“引擎”)上,我有这个环境变量.

Ping命令工作正常.但是我怎么能用java呢？我尝试使用该命令

root@639144f7c95f:/home/docker# echo $JAVA_1_PORT$RECETTEETUDIANT_JAVA_1_ENV_JAVA_HOME
tcp://172.17.0.3:999/usr/lib/jvm/java-8-openjdk-amd64
root@639144f7c95f:/home/docker# /recetteetudiant_engine_1/java_1
bash: /recetteetudiant_engine_1/java_1: No such file or directory
root@639144f7c95f:/home/docker# $JAVA_1_PORT$RECETTEETUDIANT_JAVA_1_ENV_JAVA_HOME     
bash: tcp://172.17.0.3:999/usr/lib/jvm/java-8-openjdk-amd64: No such file or directory
root@639144f7c95f:/home/docker# 

也许我必须分享一卷？我可以通过TCP协议使用Java吗？
