Hi!

This morning I wanted to do one more thing.
I performed the following steps:

  1. edited the ~/.docker/config.json file like this:
{
    "proxies": {
        "default": {
            "httpProxy": "http://myproxy.com:8080",
            "httpsProxy": "http://myproxy.com:8080",
            "ftpProxy": "http://myproxy.com:8080",
            "noProxy": "127.0.0.1,localhost"
        }
    }
}
  1. Started a new Ubuntu Docker container:
    docker run -it ubuntu bash
  2. Update succeeded!

Reading package lists... Done

So, the httpsProxy variable was missing in docker.config.json file. It’s strange, because apt servers were contacted via http and not https.

I’m still trying to understand why this is not working for docker-compose.yml prepared services.

If I try to set the proxy as explained here it doesn’t work too.
