Docker系列－Docker在Kali Linux上的安装

1. Docker 这个容器包含下面的东西

A native Linux container format that Docker calls libcontainer.
Linux kernel namespace: which provides isolation for filesystem, processes, and networks.
Filesystem isolation: each container is its own root filesystem.
Process isolation: each container runs in its own process environment.
Network isolation: separate virtual interfaces and IP addressing between containers.
Resource isolation and grouping: resource like CPU and memory are allocated individually to each
Docker container using the cgroups kernel feature.
Copy-on-write: filesystem are created with copy-on-write.
logging: STDOUT,STDERR, STDIN from the container are collected, logged, and available for analysis or trouble-shooting.
Interactive shell: you can create a pseudo-tty and attach to STDIN to provide an interactive shell to your container.

２.Docker安装需要满足的条件

Kernel 3.16 or later kernel.
Device mapper
AUFS
vfs
btrfs
ZFS( introduced in Docker 1.７）
cgroups and namespace kernel features must be supported and enabled.

检查各种条件是不是满足了：

#confirm device-mapper is installed.
ls -l /sys/class/misc/device-mapper
#check for Device Mapper in proc on Debian/Ubuntu
grep device-mapper /proc/devices
#loading the Device Mapper module
modprobe dm_mod

３. 开始安装Docker

#install docker-engine
apt-get update
apt-get install -y apt-transport-https ca-certificates
apt-get install dirmngr
#add the appropriate PGP key
apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
#add the appropriate Docker source entry.
echo 'deb  debian-stretch main' >> /etc/apt/sources.list.d/docker.list
#apt-get update again.
apt-get update
#install Docker
apt-get install docker-engine

4. 碰到的问题, 该出错信息位于term.log。

我查了下apt的Log文件，

/var/log/apt/history.log
/var/log/dpkg.log
/var/log/apt/term.log

root@kali:/usr/local/src/scheme# dpkg -l |grep aufs
ii  aufs-dkms                                         4.9+20161219-2                       amd64        DKMS files to build and install aufs
ii  aufs-tools                                        1:4.1+20161219-1                     amd64        Tools to manage aufs filesystems
root@kali:/usr/local/src/scheme# dpkg -s aufs-dkms
Package: aufs-dkms
Status: install ok installed
Priority: optional
Section: kernel
Installed-Size: 891
Maintainer: Filesystems Group <[e-mail]>
Architecture: amd64
Multi-Arch: foreign
Source: aufs
Version: 4.9+20161219-2
Depends: dkms (>= 2.1.0.0), linux-kbuild-4.9
Recommends: aufs-tools
Suggests: aufs-dev
Description: DKMS files to build and install aufs
 The aufs driver provides a union mount for Linux filesystems. It allows one
 to virtually merge the contents of several directories and/or stack them, so
 that file changes in the aufs union mount end up as changes in only one
 of the source directories.
 .
 This package contains the DKMS files to build and install aufs.
 .
 To install this package, you have to install the header files for your current
 kernel manually (usually included in the "linux-headers-").
Homepage: http://aufs.sourceforge.net/

然后我检查了两个依赖关系,dkms, 和linux-kbuild-4.9.所有的依赖关系都满足，也许是我的kernel　是4.7版本的问题吗？
我决定直接ignore这个错误。直接来启动docker .

5. 启动Docker

#startup docker
service docker start
systemctl status docker
#check docker information
docker version
docker info

6. get First container.

docker container run -it alpine sh
