同一应用程序无法通过Docker Compose发送HTTP请求 [英] Same app can't send http request by docker compose
本文介绍了同一应用程序无法通过Docker Compose发送HTTP请求的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
Spring boot
Spring boot
改造2
docker
在我的docker-compose文件中：
in my docker-compose file:
version: "3"
services:
server:
image: asubscriber/eshop:1.0.1
build: .
ports:
- 8090:8090
-
像这样从控制台运行我的应用程序（春季启动）：
Run my app (Spring boot) from console like this:
java -jar build / libs / eshop-1.0.1.jar eshop-1.0.1。 jar
java -jar build/libs/eshop-1.0.1.jar eshop-1.0.1.jar
运行成功。并成功向http请求。在这里记录：
Run success. And success to http request. Here log:

好。很好成功发送POST http请求。
Nice. It's work fine. Success send POST http request.

现在我运行 SAME MY app docker compose
Now I run SAME MY app by docker compose
docker-compose up
docker-compose up
成功运行应用程式。
但是如果我想创建http请求，则会出现错误：
Success run app. But if I want to create http request I get error:

为什么同一个应用程序无法在docker上运行？
Why same app not work from docker?
推荐答案
将此应用添加到docker中的服务中组成文件（仅网络部分）
add this to your service in docker-compose file (only the network part)
version: "3"
services:
server:
image: asubscriber/eshop:1.0.1
build:
context: .
network_mode: "host"
expose:
- 9080
这是一个使它起作用的答案，最好阅读这，如谢尔盖·佩图宁（Sergei Petunin）在上述评论中所述。
This is an answer to just make it works, it's better to read this, as Sergei Petunin mentiond in the comments above.
