From 39875a5c9f86e9155f489ac96e8891f40140d95b Mon Sep 17 00:00:00 2001 From: Rahul Sharma Date: Mon, 11 Jul 2016 19:06:19 -0400 Subject: [PATCH] updated insecure docker-registry configuration Current documentation was outdated/misleading. For CentOS, I found that they have INSECURE_REGISTRY flag in /etc/sysconfig/docker in docker version 1.10.3. For Ubuntu, latest versions of ubuntu use systemd and hence, the documentation needs to be updated.
