docker 安裝前準備-作業系統列表需要滿足如下版本的ubuntu
- Cosmic 18.10
- Bionic 18.04 (LTS)
- Xenial 16.04 (LTS)
解除安裝舊版本docker，如果安裝過的請操作如下，如果使用普通賬號執行，請按如下操作，如果有root許可權請忽略sudo，系統首次安裝請略過此步驟
$ sudo apt-get remove docker docker-engine docker.io containerd runc安裝docker ce
1.設定倉庫
$ sudo apt-get update2. 安裝包允許apt通過HTTPS使用儲存庫
$ sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common3. 新增Docker的官方GPG金鑰
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -4.驗證祕鑰
$ sudo apt-key fingerprint 0EBFCD88有如下顯示：證明安裝成功
pub rsa4096 2017-02-22 [SCEA] 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 uid [ unknown] Docker Release (CE deb) <[email protected]> sub rsa4096 2017-02-22 [S]
5.安裝穩定版倉庫
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"6.安裝docker ce
#更新apt包索引
$ sudo apt-get update7.安裝最新版本docker ce或者跳到下步安裝指定版本
$ sudo apt-get install docker-ce docker-ce-cli containerd.io8.安裝指定版本的docker ce
$ apt-cache madison docker-ce docker-ce | 5:18.09.6~3-0~ubuntu-bionic | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 5:18.09.5~3-0~ubuntu-bionic | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 5:18.09.4~3-0~ubuntu-bionic | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 5:18.09.3~3-0~ubuntu-bionic | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 5:18.09.2~3-0~ubuntu-bionic | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 5:18.09.1~3-0~ubuntu-bionic | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 5:18.09.0~3-0~ubuntu-bionic | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.06.3~ce~3-0~ubuntu | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.06.2~ce~3-0~ubuntu | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.06.1~ce~3-0~ubuntu | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.06.0~ce~3-0~ubuntu | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages docker-ce | 18.03.1~ce~3-0~ubuntu | https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu bionic/stable amd64 Packages
以5:18.09.6~3-0~ubuntu-bionic版本為例，執行如下命令
$ sudo apt-get install docker-ce=5:18.09.6~3-0~ubuntu-bionic docker-ce-cli=5:18.09.6~3-0~ubuntu-bionic containerd.io9.執行測試例項，hello-world映象,如果沒有該映象會自動下載
$ sudo 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
