docker - 无法从外部访问 Docker 容器中的应用程序

Question

docker pull kovacshuni/riptube:1.0.0-SNAPSHOT
docker run -it -P --name="riptube" kovacshuni/riptube:1.0.0-SNAPSHOT
bin/riptube &
curl -X POST -d "Hi there" localhost:8082/notify
INFO 15:55:06 c.h.r.NotificationReceiver$ - Hi there

所以这成功了。但从外部，从 docker 守护进程的主机来看，它没有。尽管有 EXPOSE 命令和 -P 参数。

docker port riptube 8082
0.0.0.0:32785
curl -X POST -d "Hi there" localhost:32785/notify
curl: (52) Empty reply from server

为什么？ :( :(

源代码here . Dockerfile 也是如此，但粘贴在下面:

 FROM frolvlad/alpine-oraclejdk8

 RUN apk add --update bash py-pip ca-certificates curl
 RUN rm -rf /var/cache/apk/*
 RUN pip install youtube-dl

 WORKDIR /opt/riptube
 ADD target/pack/ /opt/riptube
 EXPOSE 8082
 ENTRYPOINT /bin/bash
 CMD

我遇到了同样的问题:

替换这个:

private val httpBindingF = Http().bindAndHandle(ripController.route, "localhost", 8080)

有了这个:

private val httpBindingF = Http().bindAndHandle(ripController.route, "0.0.0.0", 8080)

令人惊讶的是，它对我有用!
