java - 无法从docker容器内的spring连接到redis
问题描述
我正在尝试容器化并尝试在写入 redis 的 docker 容器中运行可执行 jar。
我已经尝试了我能找到的关于 StackOverflow 的所有建议，包括：
- 无法使用jedis连接到redis
- 无法从 docker 容器连接到 redis 服务器
- 在docker中启动spring session + redis时出错
- spring server 无法使用jedis客户端连接redis
- Docker compose spring boot redis 连接问题
- 无法在 10.XX.XX.28:6379 连接到 Redis：未知错误 - 从 Spring Batch 或 Windows 机器访问时
我在 OSX High Sierra 10.13.6 上并使用最新的 Docker 桌面（社区）版本 2.0.0.0-mac81 Docker 引擎 18.09.0 Docker compose: 1.23.2
我正在使用 Homebrew 安装的 redis： Redis server v=5.0.2 sha=00000000:0 malloc=libc bits=64 build=25bb354a43384ae5
我已修改 redis.conf 文件以禁用绑定并关闭保护模式
在 /usr/local/etc/redis.conf 里面注释掉所有的绑定命令，例如
#bind 127.0.0.1 ::1
#bind 0.0.0.0 ::1
将保护模式设置为关闭
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
我正在通过 redis-cli 以这种方式收听 redis：
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"]
这是我用来尝试调试的一个简单的 spring 应用程序，然后我可以在连接到 redis 的 bash 中编译和运行它而不会出现问题。
mvn clean install
java -jar target/foo-v1.jar
curl -4 localhost:8080/set
快乐的 redis-cli 输出：

感谢您提供任何线索！
解决方案
好吧，我终于通过在自己的容器中运行 redis 来让他们说话
我像这样启动了一个redis容器：
docker run --rm -it -p 6379:6379 redis
连接的 redis-cli
redis-cli monitor
然后以这种方式启动我的示例容器：
docker run --rm -it --net=host foo
但我找不到让 docker 与本地安装的 redis 对话的方法。
我想这已经足够好了，尽管如果有一个原始问题的解决方案，我仍然会很感激
