TODO: 为何要使用 -i 和 -t
使用 docker run -p 的例子
镜像ubuntu:12.04没有vi，没法编辑/etc/apt/sources.list
现在本地有一份，想上传上去
首先映射端口(宿主的2222端口和container的33333端口映射):
docker run -i -t -p 22222:33333 fe65a2781dae /bin/bash
container上监听33333：
nc -l -p 33333 > /etc/apt/sources.list
本地使用22222端口传输:
nc localhost 22222 < sources.list
查看映射的端口
root@tankywoo-docker:~# docker ps

但是这里很好奇为啥是监听在ipv4的地址上?
删除image/container遇到的依赖关系
关于删除时的依赖关系，按照提示删除就行了
比如删除images时，需要先删除通过它创建的所有containers:
root@tankywoo-docker:~# docker rmi 666c5d65f396 3494872e31a4 62fda5e450d5 5e1829f90d6e 89554a25c998

2014/05/07 15:44:41 Error: failed to remove one or more images
root@tankywoo-docker:~# docker rm 43a7072bac7a 40b3cd8b2e42 5142a3d092a6
43a7072bac7a
40b3cd8b2e42
5142a3d092a6
且删除images时也可能会遇到依赖其它的images，比如直接删除父镜像时，就会提示需要先删除子镜像。
可以通过:
docker images --tree
来查看，不过官方提示 --tree 已经弃用了，会在以后的版本去掉.
首先清空所有containers:
root@tankywoo-docker:~# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
然后以树形结构查看依赖关系:
root@tankywoo-docker:~# docker images --tree
Warning: '--tree' is deprecated, it will be removed soon. See usage.

现在准备删除12.10版本的父镜像 cf8dc907452c, 会提示有冲突，删不掉:
root@tankywoo-docker:~# docker rmi cf8dc907452c
Error: Conflict, cf8dc907452c wasn't deleted

containers之间共享数据
docker 的 containers之间共享目录是通过 volume 。
docker run 命令使用 -v 可以绑定一个volume, -v 可以使用多次，创建多个volume:
root@tankywoo-docker:~# docker run -i -t -v /tmp/tankywoo --name data ubuntu:newtest /bin/bash [6/3516]
使用 mount 看到 /tmp/tankywoo 已经被mount了:
root@fec65f523cef:/# mount
none on / type aufs (rw,relatime,si=f7ac8b1595d13ed9)
...
/dev/disk/by-uuid/b77aed99-bb9b-4881-9702-4ed204fe5d46 on /tmp/tankywoo type ext3 (rw,relatime,errors=remount-ro,user_xattr,acl,barrier=1,data=ordered)
查看 /tmp/tankywoo 目录下，是空的:
root@fec65f523cef:/tmp/tankywoo# ls
root@fec65f523cef:/tmp/tankywoo#
然后在宿主机新建一个container，来绑定这个volume:
按照 docker run 的命令行参数:
--volumes-from=[]: Mount volumes from the specified container(s)
有问题:
root@tankywoo-docker:/tmp/tankywoo# docker run -i -t --volumes-from=["data"] ubuntu:newtest /bin/bash [21/158]
2014/05/08 15:58:19 Error: Cannot start container 5d83dcaf8f0220024e0403a362c0512a8218cfcb45dc911df5d2cd37f9a4e8a4: Container [data] not found. Impossible to mount its volumes
必须像short option的方式使用:
root@tankywoo-docker:/tmp/tankywoo# docker run -i -t --volumes-from data ubuntu:newtest /bin/bash
root@d100d9604b4b:/# mount
none on / type aufs (rw,relatime,si=f7ac8b15b25036d9)
...
/dev/disk/by-uuid/b77aed99-bb9b-4881-9702-4ed204fe5d46 on /tmp/tankywoo type ext3 (rw,relatime,errors=remount-ro,user_xattr,acl,barrier=1,data=ordered)
也可以看到 /tmp/tankywoo 目录，并且是空的，然后新建一个文件:
root@d100d9604b4b:/tmp/tankywoo# ls
root@d100d9604b4b:/tmp/tankywoo# touch file
root@d100d9604b4b:/tmp/tankywoo# ls
file
再看看之前那个container:
root@fec65f523cef:/tmp/tankywoo# ls
file
也有这个文件了
参考
退出container但是保持运行
默认情况下，如果使用ctrl-c退出container,那么container也会stop
按ctrl-p ctrl-q可以退出到宿主机，而保持container仍然在运行
Docker被墙
关于 Docker 被墙，老甘的文章里提到的修改hosts文件，先mark，未验证:
# /etc/hosts
54.234.135.251 get.docker.io
54.234.135.251 cdn-registry-1.docker.io
遗留的问题
有时docker执行不了任何命令(会卡住)，包括重启docker server，在日志里看到这些:

什么是Layer
Docker images are built up in layers. So, for instance, if you need to run WordPress, you would build the Ubuntu layer, add a layer for Apache2 web server, add a PHP layer and then a layer for the WordPress files. Lower layers can be re-used. We might take the PHP layer and layer on Drupal instead of WordPress, or update our WordPress layer with a newer version or Wordpress.
Because we can re-use layers, we can make new docker images very cheaply. We can create a new docker image by changing just a single line of one file and we do not have to rebuild the whole stack.
The beauty of docker images being “just files” means that the difference between two docker images is just a diff of the files they contain.
概念上的问题
The Docker Guidebook 的简单对比:
Image : An image is a read only layer used to build a container. They do not change.
Container : Is basically a self contained runtime environment that is built using one or more images. You can commit your changes to a container and create an image.
index / registry : These are public or private servers where people can upload their repositories so they can easily share what they made.
Repository : A repository is a group of images located in the docker registry. There are two types of repositories, Top level and user repositories. Top level repositories don't have a '/' in the name and they are usually reserved for base images. These Top level repositories is what most people build their repositories on top of. They are controlled by the maintainers of Docker. User repositories are repositories that anyone can upload into the registry and share with other people.
说直接点，Image和Container最容易理解和对比，它俩的关系就像类与类的实例这两的关系一样。
其实Index和Registry也有区别，主要就是Index存储的是用户信息、images的checksum；而Registry存储的是images。具体见官方文档Registry & Index Spec。
另外，关于Repository与Registry和Image又是什么关系?

以这个为例
这里的ubuntu是image名称吗？(后面解答)
一个image完整的名称是:
username/image_name:tag
docker整体和Github非常像，image管理也不例外。
其中，如果username没有写，则被认为是官方认证过的image。如前面提到，如果tag没有写，则被认为tag是lastest。
另外，如果username写了，如 tankywoo/ubuntu，则会在官方index中查找username为tankywoo的ubuntu仓库；如果写的如上10.2.15.190:5000/tankywoo，则10.2.15.190:5000则被认为是第三方registry的地址。
所以如上所说，ubuntu并不是image的名称，而是repository的名称。
再看看/var/lib/docker/ 下的 repositories-aufs，这是一个repositories的json列表:
root@tankywoo-docker:~/docker-registry-master# cat /var/lib/docker/repositories-aufs | python -m json.tool
{
"Repositories": {
