新版本的docker再次审判了我们，对于需要自建私有仓库的朋友们需要注意下面的说明。
这个是新启动的docker。
root@docker:/opt/software/DOCKER-FILES/elasticsearch# ps -ef | grep docker

修改。

# Only systemd 226 and above support this version.

修改/etc/default/docker。
root@docker:/opt/software/DOCKER-FILES/elasticsearch# vim /etc/default/docker
# Docker Upstart and SysVinit configuration file
#
# THIS FILE DOES NOT APPLY TO SYSTEMD
#
# Please see the documentation for "systemd drop-ins":
# https://docs.docker.com/engine/articles/systemd/
#
# Customize location of Docker binary (especially for development testing).
#DOCKERD="/usr/local/bin/dockerd"
# Use DOCKER_OPTS to modify the daemon startup options.
#DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
DOCKER_OPTS="--insecure-registry 192.168.0.240"
# If you need Docker to use an HTTP proxy, it can also be specified here.
#export http_proxy="http://127.0.0.1:3128/"
# This is also a handy place to tweak where Docker's temporary files go.
#export TMPDIR="/mnt/bigdrive/docker-tmp
重启docker。

. ok

这样环境变量就生效了。
