我正在使用Docker for Mac 1.12.0-rc4-beta19 使用以下dockerfile和docker-compose.yml构建的容器。
我想用http://localhost:1344
从主机操作系统浏览器连接到容器的1344端口
但连接失败了。
我正在使用容器的1344来测试瓶子(python轻量级Web框架)应用程序
为什么无法从主机连接到容器的端口?
docker-compose.yml:
version: '2'

datastore:
image: busybox:latest
volumes:
- ./share:/share_to_container

端口8080连接正确,但1344失败

如果通过&#34;主机浏览器&#34;你的意思是你的Mac,你当然需要按照建议从端口映射中删除主机。您无法连接的原因是实际的Docker主机是在Mac和Docker之间运行的(xhyve)虚拟机。 Docker会自动发布Mac和容器之间的端口,只需删除主机,即- "1344:1344"
(Fyi,在您的设置中,您需要通过VM主机进行连接,这对您来说并不是很有帮助。)
如果您仍有问题,请发布任何错误和重现步骤。

因此,在您发布Dockerfile后,它看起来不像您正在运行任何东西?您将CMD
操作设置为bash
,并且不会覆盖docker-compose.yml
中的操作。我对容器完全有点惊讶(因为它只会运行bash并退出)。
这些文件是否完整?
另外,您可能希望重新格式化/ lint您的Dockerfile以获得最佳实践。

您看到了this forum topic吗?
所以只需运行一个容器并调用'ifconfig'命令。输出示例:
bash-4.3# ifconfig
eth0 Link encap:Ethernet HWaddr 02:42:AC:11:00:02
inet addr:172.17.0.2 Bcast:0.0.0.0 Mask:255.255.0.0

因此,来自示例的VM的IP是172.17.0.2
