# Debian操作系统安装Docker
|
||
##支持的版本
|
||
- Debian testing stretch (64-bit)
|
||
- Debian 8.0 Jessie (64-bit)
|
||
- Debian 7.7 Wheezy (64-bit)
|
||
##预安装
|
||
Docker支持64位、内核高于3.10的Debian操作系统，内核低于3.10将导致数据丢失和系统不稳定等问题。
|
||
查看内核版本使用以下命令：
|
||
```
|
||
$ uname -r
|
||
```
|
||
###更新APT仓库
|
||
Docker的APT仓库包含了1.7.1及以上版本的Docker，安装前需要更新APT设置，来使用新的仓库：
|
||
1. 清理旧的仓库信息
|
||
```sh
|
||
$ apt-get purge lxc-docker*
|
||
$ apt-get purge docker.io*
|
||
```
|
||
2. 更新和安装软件包
|
||
```sh
|
||
$ apt-get update
|
||
$ apt-get install apt-transport-https ca-certificates
|
||
```
|
||
3. 添加GPG键
|
||
```
|
||
$ apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
|
||
```
|
||
4. 添加APT源
|
||
编辑文件 ```/etc/apt/sources.list.d/docker.list```,清理已存在的信息，写入APT源地址内容。以下以Debian Jessie为例，非Jessie版本的系统注意修改为自己对应的代号。
|
||
```sh
|
||
$ sudo cat <<EOF > /etc/apt/sources.list.d/docker.list
|
||
deb https://apt.dockerproject.org/repo debian-jessie main
|
||
EOF
|
||
```
|
||
|
||
其他两个版本内容：
|
||
```
|
||
deb https://apt.dockerproject.org/repo debian-wheezy main
|
||
```
|
||
```deb https://apt.dockerproject.org/repo debian-stretch main
|
||
```
|
||
5. 校验安装结果
|
||
```
|
||
$ apt-cache policy docker-engine
|
||
docker-engine:
|
||
Installed: 1.11.0-0~jessie
|
||
Candidate: 1.11.0-0~jessie
|
||
Version table:
|
||
*** 1.11.0-0~jessie 0
|
||
500 https://apt.dockerproject.org/repo/ debian-jessie/main amd64 Packages
|
||
100 /var/lib/dpkg/status
|
||
.....
|
||
```
|
||
以后，当执行```apt-get upgrade```等命令时，将使用新设置的的APT源。
|
||
|
||
##安装Docker
|
||
```
|
||
$ sudo apt-get install docker-engine
|
||
```
|
||
##为非root用户授权
|
||
```
|
||
# 如果没有就建立一个Docker组.
|
||
$ sudo groupadd docker
|
||
|
||
# 增加一个用户（用真实的名字替换下面的${USER}）到docker组,需重登陆来生效。
|
||
$ sudo gpasswd -a ${USER} docker
|
||
|
||
# 重启docker服务
|
||
$ sudo service docker restart
|
||
```
|
||
##更新Docker
|
||
```
|
||
$ apt-get upgrade docker-engine
|
||
```
|
||
##卸载Docker
|
||
```sh
|
||
# 卸载软件包
|
||
$ sudo apt-get purge docker-engine
|
||
|
||
#卸载依赖包
|
||
$ sudo apt-get autoremove --purge docker-engine
|
||
|
||
#如有必要，执行以下命令，删除全部镜像、容器、数据卷和其他docker相关用户信息:
|
||
$ rm -rf /var/lib/docker
|
||
|
||
```
|
