如果我想构建我的Dockerfile,它无法连接到网络或至少DNS:

E: Unable to locate package build-essential
INFO[0001] The command "/bin/sh -c apt-get update -qq && apt-get install -y build-essential libpq-dev" returned a non-zero code: 100
但是如果我通过docker run
命令运行完全相同的命令,它就可以正常工作:
docker run --name="test" ruby /bin/sh -c 'apt-get update -qq && apt-get install -y build-essential libpq-dev'
有人知道为什么 docker build
不起作用吗?我尝试了StackOverflow上所有与DNS相关的提示,例如使用 --dns 8.8.8.8 启动docker等。
