java spring-boot docker redis

我正在试验容器化，并试图在写到redis的docker容器中运行一个可执行的jar。

我已经在StackOverflow上尝试了所有我能找到的建议，包括：

我在OSX高塞拉10.13.6和使用最新的码头桌面(社区)版本2.0.0.0-mac81码头引擎18.09.0码头组成: 1.23.2

我使用的是由Homebrew安装的redis : Redis server v=5.0.2 sha=00000000:0 malloc=libc bits=64 build=25bb354a43384ae5

我修改了redis.conf文件以禁用绑定并关闭保护模式

在/usr/local/etc/redis.conf中注释掉所有绑定命令。 

    #bind 127.0.0.1 ::1
    #bind 0.0.0.0 ::1

将保护模式设置为off 

    protected-mode no

我以这种方式运行redis服务器以启用这些更改： 

redis-server /usr/local/etc/redis.conf

我通过redis-cli听红调： 

redis-cli monitor

这是我的Dockerfile： 

FROM alpine:3.2
RUN apk --update add openjdk7-jre
RUN apk add bash
ENV \
    LC_ALL=en_US.UTF-8 \
    GRADLE_USER_HOME=/tmp
RUN mkdir -p /var/foo/helloredis
ENV PATH "$PATH:."
ENV CLASSPATH "$CLASSPATH:."
EXPOSE 8080
COPY target/foo-v1.jar  /var/foo/helloredis
WORKDIR /var/foo/helloredis
#ENTRYPOINT ["/bin/bash"]
ENTRYPOINT ["java", "-jar", "foo-v1.jar"]

这里有一个简单的spring应用程序，我用它来调试它，然后我可以在bash中编译和运行它，它连接到redis，没有问题。 

mvn clean install
java -jar target/foo-v1.jar
curl -4 localhost:8080/set

满意的红宝石输出：
