问题
I'm trying to install Docker on a Windows computer but I get this message:
Running pre-create checks...
(default) No default Boot2Docker ISO found locally, downloading the latest release...
Error with pre-create check: "Get https://api.github.com/repos/boot2docker/boot2docker/releases/latest: dial tcp 192.30.252.124:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."
Looks like something went wrong in step 'Checking if machine default exists'...
Press any key to continue...
Any suggestions on how to resolve this?
回答1:
You may behind a firewall. If so, you will need to configure an http proxy.
According to https://github.com/boot2docker/boot2docker-cli/issues/230 you can do this one of a couple of ways:
(1) Edit start.sh and add the following before boot2docker.exe is called
export HTTP_PROXY=<proxy>
export HTTPS_PROXY=<proxy>
(2) Add HTTP_PROXY and HTTPS_PROXY (and their values) to your System Variables or User Variables in your Windows config.
The proxy value should be of the form http://hostname:port

Editing the start.sh file may come up with other error things.
Instead that, just put your boot2docker.iso in below location as.
c:\user\USERNAME\\.docker\machine\cache
and restart your Docker terminal.
