docker安装

已经做了安装好docker,docker-compose的uhost镜像docker-host，可以直接从镜像创建。

安装

见https://get.daocloud.io/

配置

通过daocloud加速下载

见https://dashboard.daocloud.io/mirror

echo "DOCKER_OPTS=\"\$DOCKER_OPTS --registry-mirror=http://7f90de07.m.daocloud.io\"" | sudo tee -a /etc/default/docker
sudo service docker restart

更改docker存储目录

请不要用link ，会出现问题

echo "DOCKER_OPTS=\"\$DOCKER_OPTS -g /data/docker/data\"" | sudo tee -a /etc/default/docker
sudo service docker restart

添加私有库

echo "DOCKER_OPTS=\"\$DOCKER_OPTS --insecure-registry 10-10-104-3:8001\"" | sudo tee -a /etc/default/docker

sudo service docker restart

注：ubuntu 系统，本质是修改/etc/default/docker文件配置即可

如下为改好的配置文件（最后3行）

修改的3行作用分别为：

1.添加daocloud加速

2.添加私有库，可以pull，push到私有库

3.修改docker存储目录为-g /data/docker/data ,这步根据需要修改。

# 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"

# 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"

DOCKER_OPTS="$DOCKER_OPTS --registry-mirror=http://b8399632.m.daocloud.io"

DOCKER_OPTS="$DOCKER_OPTS --insecure-registry 10.10.97.40:8001"

DOCKER_OPTS="$DOCKER_OPTS -g /data/docker/data"
