默認狀況下，Docker只容許經過unix socket通訊操做Docker daemon，但有時咱們想經過HTTP調用其Rest API，需單獨配置啓動參數html
爲了使配置永久生效，在Ubuntu環境下修改其配置文件/etc/default/docker，(centos : /etc/sysconfig/docker) 加入DOCKER_OPTS="-H=unix:///var/run/docker.sock -H=0.0.0.0:6732"，重啓Docker服務，可經過瀏覽器訪問設置主機：端口號（6372）/ Docker API操做Dockerdocker
- # Docker Upstart and SysVinit configuration file
- # Customize location of Docker binary (especially for development testing).
- #DOCKER="/usr/local/bin/docker"
- # Use DOCKER_OPTS to modify the daemon startup options.
- #DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
- DOCKER_OPTS="-H=unix:///var/run/docker.sock -H=0.0.0.0:6732"
- # 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"
