Question

我已经在Docker内部设置了一个简单的nameko服务器，但是当我尝试从主机（Mac）卷曲时，我得到一个空的答复。我看了其他similar个问题，但对我来说不起作用，我得到：

$ curl http://$(echo docker-machine ip default):8080
curl: (6) Couldn't resolve host 'docker-machine'
curl: (6) Couldn't resolve host 'ip'
curl: (6) Couldn't resolve host 'default'

该问题中的OP引用了一些用户，他们向他们解释了为什么他们获得了上述帮助，但是我再也找不到该用户的评论。

在我看来，它似乎已连接，但由于某种原因，答复为空：

$curl -i localhost:8080/get/42
curl: (52) Empty reply from server

这是文件设置：

#install_anaconda.sh
#!/bin/bash
set -e
curl -O https://repo.anaconda.com/archive/Anaconda3-2019.03-Linux-x86_64.sh
bash Anaconda3-2019.03-Linux-x86_64.sh -b
