嗨,运行docker:引擎:在Mac 10.12.6上为17.12.0-ce
我正在使用build_image功能。
FROM openjdk:8-jdk-alpine AS BUILD_IMAGE
ENV APP_ENVIROMENT=dev
ENV APP_RUNTIME=docker
ENV BUILD_HOME=/build
COPY . $BUILD_HOME
WORKDIR $BUILD_HOME
RUN wget http://xxx.xxx.xxx.xxx:8081
出现以下错误。我很确定服务器可以从我的笔记本电脑/ WiFi和VPN访问
...

Step 7/16 : RUN wget http://xxx.xxx.xxx.xxx:8081

Connecting to xxx.xxx.xxx.xxx:8081 (xxx.xxx.xxx.xxx:8081)
wget: can't connect to remote host (xxx.xxx.xxx.xxx): Host is unreachable
好像是DNS问题,我的/etc/resolv.conf很好,我很确定机器可以访问。看起来我网络上的某些计算机可以访问,而其他计算机则无法访问。
我可以测试
RUN ping xxx.xxx.xxx.xxx
结果:
PING xxxxxx.mydomain.com (xxx.xxx.xxx.xxx): 56 data bytes
--- xxxxxx.mydomain.com ping statistics ---
4 packets transmitted, 0 packets received, 100% packet loss
The command '/bin/sh -c ping -c 4 xxxxxx.mydomain.com' returned a non-zero code: 1
更新。添加名称以使其清晰。
FROM openjdk:8-jdk-alpine AS BUILD_IMAGE
ENV APP_ENVIROMENT=dev
ENV APP_RUNTIME=docker
ENV BUILD_HOME=/build
COPY . $BUILD_HOME
WORKDIR $BUILD_HOME
RUN wget http://myserver.domain.net:8081
Docker构建的结果:

显然,您可以看到docker正在解决I.P,并且我的笔记本电脑可以连接。
最佳答案
问题按以下方式解决:https://success.docker.com/article/How_do_I_configure_the_default_bridge_(docker0)_network_for_Docker_Engine_to_a_different_subnet
jetty 桥与我的网络冲突。我们需要在daemon.json中输入
{
"bip": "172.26.0.1/16"
}
您可以使用任何适合您的值。
