1. 先对系统进行更新
1.1 apt-get upgrade
1.2 去中国关于dockers的网站
1.3 安装docker
curl -sSL https://get.daocloud.io/docker | sh
1.4 如果你的电脑没有安装curl,执行:sudo apt install curl
1.5 若报错说
2 安装docker(ubuntu 16.04)
Prerequisites
To follow this tutorial, you will need the following:
- 64-bit Ubuntu 16.04 server
- Non-root user with sudo privileges Initial Setup Guide for Ubuntu 16.04 explains how to set this up.)
Note: Docker requires a 64-bit version of Ubuntu as well as a kernel version equal to or greater than 3.10. The default 64-bit Ubuntu 16.04 server meets these requirements.
All the commands in this tutorial should be run as a non-root user. If root access is required for the command, it will be preceded by sudo
. Initial Setup Guide for Ubuntu 16.04 explains how to add users and give them sudo access.
Step 1 — Installing Docker
The Docker installation package available in the official Ubuntu 16.04 repository may not be the latest version. To get the latest and greatest version, install Docker from the official Docker repository. This section shows you how to do just that.
First, add the GPG key for the official Docker repository to the system:
- curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Add the Docker repository to APT sources:
- sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
Next, update the package database with the Docker packages from the newly added repo:
- sudo apt-get update
Make sure you are about to install from the Docker repo instead of the default Ubuntu 16.04 repo:
- apt-cache policy docker-ce
You should see output similar to the follow:
Output of apt-cache policy docker-ce
docker-ce:
Installed: (none)
Candidate: 17.03.1~ce-0~ubuntu-xenial
Version table:
17.03.1~ce-0~ubuntu-xenial 500
500 https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages
17.03.0~ce-0~ubuntu-xenial 500
500 https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages
Notice that docker-ce
is not installed, but the candidate for installation is from the Docker repository for Ubuntu 16.04. The docker-ce
version number might be different.
Finally, install Docker:
- sudo apt-get install -y docker-ce
- 注意:有可能运行因为docker是高版本出错
- 因为使用docker-er比install docker.io下载的版本高,后者属于老版本安装
Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it‘s running:
- sudo systemctl status docker
The output should be similar to the following, showing that the service is active and running:
Output
● docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
Active: active (running) since Sun 2016-05-01 06:53:52 CDT; 1 weeks 3 days ago
Docs: https://docs.docker.com
Main PID: 749 (docker)
Installing Docker now gives you not just the Docker service (daemon) but also the docker
command line utility, or the Docker client. We‘ll explore how to use the docker
command later in this tutorial.
