Configuring a private registry to use a proxy server
Configure the Docker client
On the Docker client, create or edit the file ~/.docker/config.json in the home directory of the user that starts containers. Add JSON similar to the following example. Substitute the type of proxy with httpsProxy or ftpProxy if necessary, and substitute the address and port of the proxy server. You can also configure multiple proxy servers simultaneously.
+
You can optionally exclude hosts or ranges from going through the proxy server by setting a noProxy key to one or more comma-separated IP addresses or hosts. Using the * character as a wildcard for hosts and using CIDR notation for IP addresses is supported as shown in this example:
+
{
"proxies":
{
"default":
{
"httpProxy": "http://192.168.1.12:3128",
"httpsProxy": "http://192.168.1.12:3128",
"noProxy": "*.test.example.com,.example2.com,127.0.0.0/8"
}
}
}+ Save the file.
When you create or start new containers, the environment variables are set automatically within the container.
Use environment variables
Set the environment variables manually
When you build the image, or using the --env flag when you create or run the container, you can set one or more of the following variables to the appropriate value. This method makes the image less portable, so if you have Docker 17.07 or higher, you should configure the Docker client instead.
