安装docker
主机环境 ubuntu16.04
curl -sSL https://get.daocloud.io/docker >>install.sh
sh install.sh --mirror Aliyun
测试安装完成
root@base2018:/home/tb# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
ca4f61b1923c: Pulling fs layer
docker: error pulling image configuration: Get https://dseasb33srnrn.cloudfront.net/registry-v2/docker/registry/v2/blobs/sha256/f2/f2a91732366c0332ccd7afd2a5c4ff2b9af81f549370f7a19acd460f87686bc7/data?Expires=1523309522&Signature=Infe2tgv51xWB5QQA0EaDmJv0ETkvaewuieEpDGkLlMKQR9a4Seglpmk1sJhFkypTPUWBwvfUK6JIem5Jiwk1J9PITbvuTAs3w55weLM3cy3TaGF3so5QJgQKY9TsAaQ7Zi9qnLaZ8PexJlF9lkSvFEP7KiW640m72n6MzMVBoM_&Key-Pair-Id=APKAJECH5M7VWIS5YZ6Q: net/http: TLS handshake timeout.
See 'docker run --help'.
出现net/http: TLS handshake timeout，一般是镜像在墙外，够不着手。
我们手动加一个配置
root@base2018:/home/tb# vim /etc/docker/daemon.json
内容如下：
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}
然后重启docker，看看状态
root@base2018:/home/tb# service docker stop
root@base2018:/home/tb# service docker start
root@base2018:/home/tb# service docker status
安装成功
root@base2018:/home/tb# docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

构件自己的docker环境
从phpdocker.io构件自己需要的php环境，generate project archive之后是一个zip包，里面内容大概如下
root@base2018:/home/tb# unzip xincron.zip
Archive: mycron.zip
inflating: phpdocker/README.md
inflating: phpdocker/README.html
inflating: phpdocker/php-fpm/Dockerfile
inflating: phpdocker/php-fpm/php-ini-overrides.ini
inflating: phpdocker/nginx/nginx.conf
inflating: docker-compose.yml
然后需要在能引用到docker-compose.yml 的地方，执行
root@base2018:/home/tb# docker-compose up
The program 'docker-compose' is currently not installed. You can install it by typing:
apt install docker-compose
没有安装docker-compose，那么安装一下，注意用的是daocloude的镜像
root@base2018:/home/tb# curl -L https://get.daocloud.io/docker/compose/releases/download/1.20.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

root@base2018:/home/tb# chmod +x /usr/local/bin/docker-compose
再次 docker-compose up，经过以下输出。等待。。
root@base2018:/home/tb# docker-compose up

查看docker镜像状态
root@base2018:/home/tb# docker-compose ps

这里对比一下刚刚压缩包里的配置文件
version: "3.1"
services:
webserver:

container_name: xincron-webserver
working_dir: /application
volumes:
- .:/application

php-fpm:

working_dir: /application
volumes:
- .:/application
- ./phpdocker/php-fpm/php-ini-overrides.ini:/etc/php5/fpm/conf.d/99-overrides.ini
对比一下可以发现一些东西，对吧。
