适用于Mac 1.12.0的Docker:如何从容器连接到主机 [英] Docker for mac 1.12.0: how to connect to host from container
问题描述
我在os x 10.10上更新了docker，因此它现在使用os x本机虚拟化.但是，我发现很难从nginx容器中连接到主机.我试过了:
I've updated docker on my os x 10.10, so it's now using os x native virtualization. However, I've found it tricky to connect to my host machine from within my nginx container. I tried this:
/sbin/ip route|awk '/default/ { print $3 }'
得到答案:
172.17.0.1
然后我在docker-compose.yml中使用了这个IP:
Then I used this ip in docker-compose.yml:
extra_hosts:
- "master:172.17.0.1"
但尽管如此，我仍然收到错误消息:
But nonetheless I keep getting errors:
172.17.0.1 - - [21/Jul/2016:09:33:46 +0000] "GET /api HTTP/1.1" 502 575 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36" "-"

请注意以下部分:client: 172.17.0.1.由于我已经从主机发出请求，因此证明我第一步中获得的ip是正确的.但是仍然没有建立连接.
Please note this part: client: 172.17.0.1. Since I've made request from host machine, it proves that ip I got in first step was correct. But connection wasn't established anyway.
我想强调一下，从FROM WITHIN容器连接到主机时遇到问题，反之亦然.
I want to stress out that I have a problem connecting FROM WITHIN container TO host and not vice versa.
我做错了什么?谢谢！
推荐答案
我遇到了同样的问题，并且发现了这个问题
I am having the same problem and I've found this
https://docs.docker.com/docker-for-mac/networking/#/known-limitations-use-cases-and-workarounds
注意段落我想从容器连接到主机上的服务"
Notice paragraph 'I want to connect from a container to a service on the host'
我还没有尝试过，因为我正在寻找更具体的解决方案(除了在别名中添加别名之外)...
I haven't yet tried it because I am looking for a more concrete solution (anyway other than adding alias to my lo address)...
如果有人在上面，请告知！
If somebody has something on it please inform!
