从外部docker-compose容器连接到docker容器 [英] Connecting to docker container from outside docker-compose container

问题描述

我们的两个服务

我们有LXV virtual-machine-1 ，其中我们有docker-compose与 service-1 和其他服务。
我们还有另一个LXV virtual-machine-2 ，其中我们有docker-compose与 service-B 和新的其他服务。假设这两个服务使用端口80和81

问题

如何从 service-1 到 service-B 在单独的LXV虚拟机中的单独docker组合中。

我们尝试了什么

我们在LXV virtual-machine-上更改了个主机文件2 ，添加映射服务1和 virtual-machine-1 的I​​P地址。 虚拟机-1 具有配置的转发代理，并将请求转发到 service-1

ping服务1 和 telnet服务1 80 $ c> virtual-machine-2 工作。
但是，在 virtual-machine-2 的docker-compose中，相同的ping无法在容器内工作。

hosts 文件。因此我们需要将 service-B IP映射的记录添加到主机文件到 service中-1 容器主机文件。
我们修改了start sh脚本来做到这一点。

Our two services

We have LXV virtual-machine-1 where we have docker-compose with service-1 and other services. We have another LXV virtual-machine-2 where we have docker-compose with service-B and new other services. Let's assume these two services use ports 80 and 81

Question

How to connect from service-1 to service-B in separate docker compositions in separate LXV virtual machines.

What we tried

We changed hosts file on LXV virtual-machine-2 by adding mapping service-1 and ip address of virtual-machine-1. virtual-machine-1 has a forward proxy which is configured and forwards requests to service-1

ping service-1 and telnet service-1 80 from virtual-machine-2 work. However, same ping does not work inside the container in docker-compose of virtual-machine-2.

解决方案

As it turns out, docker container has default hosts file. So we needed to add a record of service-B IP mapping into hosts file into service-1 container hosts file. We modified starting sh script to do so.
