From 0705a7ed15f090b3be64f2995d1c9fff51edc2f1 Mon Sep 17 00:00:00 2001 From: Cédric Ollivier Date: Thu, 9 Nov 2017 06:05:06 +0100 Subject: Remove the former Dockerfile MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit opnfv/functest had been split into multiple containers based on Alpine (See Docker Slicing [1]) during Euphrates. As ARM is being switching to them, we can safely remove the related files.

You can listen to port 2375 on all network interfaces with --H tcp://0.0.0.0:2375, where 0.0.0.0 means any available IP address on host, and -tcp://0.0.0.0:2375 indicates that port 2375 is listened on any IP of daemon host. -If we want to make docker server open on the Internet via TCP port, and only trusted -clients have the right to access the docker server in a safe manner, port 2376 for -encrypted communication with the daemon should be listened. It can be achieved to -create certificate and distribute it to the trusted clients. - -Through creating self-signed certificate, and using --tlsverify command when running -Docker daemon, Docker daemon opens the TLS authentication. Thus only the clients -with related private key files can have access to the Docker daemon's server.
