ECONNREFUSED nodeJS在docker容器中具有express [英] ECONNREFUSED nodeJS with express inside docker container

问题描述

我正在构建一个在docker容器中运行的nodejs应用...

I'm building up a nodejs app which is running in the docker container...

这是我用来运行容器的命令...

This is the command I used to run the container...

sudo docker run -it --rm -p 3000:6001 --name xxx-running xxx

在命令行上方执行，得到以下输出。

Execute above command line, got following output..

    Running on Locally
    AppEnv {
      isLocal: true,
      app: {},
      services: {},
      name: 'xxx',
      port: 6001,
      bind: '0.0.0.0',
      urls: [ 'http://localhost:6001' ],
      url: 'http://localhost:6001' }
   App started on port http://localhost:6001

启动该应用程序将调用第三方api，因此请求模块是必需的。
每次调用请求时，都会出现以下错误...

Since the app will call third party api, so the request module is required. Each time when a request is invoked, I got following error...

{ [Error: connect ECONNREFUSED 192.155.253.83:443]
 code: 'ECONNREFUSED',
 errno: 'ECONNREFUSED',
 syscall: 'connect',
 address: '192.155.253.83',
 port: 443 }

我知道这可能是因为localhost条目所致，但是如何更改它？

I know maybe it's because of the localhost entry, but how can I change this?

推荐答案

您是否将第三方api托管在本地主机上的docker容器中？如果是，那么您需要确保第三方api docker容器共享同一网络。请参阅 https://docs.docker.com/engine/userguide/networking/ 。我尝试访问其余端点时遇到了相同的问题，我认为它将与本地主机一起解决，因为它在容器内部的docker上运行。以下是帮助我解决问题的步骤序列：

Are you hosting your third party api inside a docker container on localhost? If yes then you need to make sure that third-party api docker container is sharing same network. See https://docs.docker.com/engine/userguide/networking/. I had same problem trying to access rest endpoint which i assumed will be resolved with local host since it is running on my docker inside container. Here is a sequence of steps which helped me resolved issue:

1. 执行 docker network ls 查看您有多少个桥驱动程序。在我的情况下，我有2个和使用不同容器的容器


2. 如果您有多个桥接驱动程序，请确保您启动的容器将使用相同的桥接网络相互通信 docker run -d -t --network networkname --name containername


3. 运行 docker network inspect networkname 。您将看到带有容器列表的网络详细信息。每个容器将具有与其关联的IPv4Address。使用这些地址的值而不是localhost或127.0.0.1进行通信

1. Execute docker network ls to see how many bridge drivers you have. In my case i had 2 and containers where using different ones
2. If you have multiple bridge drivers, make sure that you starting your containers which will be talking with each other using same bridge network docker run -d -t --network networkname --name containername
3. Run docker network inspect networkname. You will see details of network with list of containers. Each container will have IPv4Address associated with it. Use value of these address to communicate instead of localhost or 127.0.0.1
