Docker入门之安装教程

2,428 阅读3分钟

本篇介绍了在Mac OS, Windows, Linux下的Docker安装方法。

先来一个官方的介绍:

Docker Engine is available for Linux (CentOS, Debian, Fedora, Oracle Linux, RHEL, SUSE, and Ubuntu) or Windows Server operating systems and is based on containerd - the open source container runtime project that Docker donated to the Cloud Native Computing Foundation (CNCF) in 2017. It is available as both a free community-supported engine and as a commercially-supported enterprise engine (Docker Engine-Enterprise) that also forms the foundation for an enterprise container platform.

基本上全平台已经覆盖,英文好的同学,可以自取。

Mac OS上的Docker安装方法方法一官方dmg:

官方下载地址:

Docker Descktop for Mac

对系统的要求:

Requires Apple Mac OS Sierra 10.12 or above. Download Docker Toolbox for previous OS versions.

只要系统是 Mac OS Sierra 10.12以上即可。

下载完Docker.dmg安装包之后,双击即可以安装,可能需要系统管理员权限,输入密码即可。

运行过后,小图标:

安装完之后,在终端工具中,使用docker version来查看Docker版本。

方法二brew cask:

brew update

brew cask install docker

删除的方法, 还需要手动删除Docker.app

brew cask uninstall docker上面的命令将会把Docker安装在Applications目录下。

Windows上Docker安装官方下载地址:Docker Desktop for Windows

对系统的要求:

Requires Microsoft Windows 10 Professional or Enterprise 64-bit. For previous versions get Docker Toolbox.

需要Windows 10专业版及企业的64位版本,在Windows server 2016以上亲测是可用的。Windows 8/7/Vista/Xp之类的,就别想了,老实去装Windows 10或者虚拟机中去使用。

Linux上Docker安装Centos中Docker安装方法先删除旧的版本(如果没有可以跳过)

$ sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine安装必须的依赖:

$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2添加stable的Docker-ce的源:

$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo安装docker-ce:

$ sudo yum install docker-ce docker-ce-cli containerd.io选择指定的安装版本(可选)

$ yum list docker-ce --showduplicates | sort -r

docker-ce.x86_64 3:18.09.1-3.el7 docker-ce-stabledocker-ce.x86_64 3:18.09.0-3.el7 docker-ce-stabledocker-ce.x86_64 18.06.1.ce-3.el7 docker-ce-stabledocker-ce.x86_64 18.06.0.ce-3.el7 docker-ce-stable我们来举个例子,比如我们要安装3:18.09.1-3.el7这个版本,使用如下命令结构:

$ sudo yum install docker-ce- docker-ce-cli- containerd.io命令说明:

第一部分是docker-ce,第二部分是版本号18.09.1,看明白了吗?就是这样子:

$ sudo yum install -y docker-ce-18.09.1 docker-ce-cli-18.09.1启动服务并测试一下:

启动服务

sudo systemctl start docker

来一个Hello World吧

sudo docker run hello-worldUnable to find image 'hello-world:latest' locallylatest: Pulling from library/hello-world1b930d010525: Pull completeDigest: sha256:2557e3c07ed1e38f26e389462d03ed943586f744621577a99efb77324b0fe535Status: Downloaded newer image for hello-world:latest

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

关于升级&删除:

升级:

更新所有

yum -y update

更新指定

yum -y update docker-ce docker-ce-cli containerd.io删除:

sudo yum remove docker-ce

删除文件系统

sudo rm -rf /var/lib/dockerDebian中Docker的安装方法删除旧的版本(可跳过)

官方文档:Install Docker Compose

在Mac/Windows中,已经集成了docker-compose命令

在WindowsServer中 先启动PowerShell

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12然后运行如下命令:

Invoke-WebRequest "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-Windows-x86_64.exe" -UseBasicParsing -OutFile $Env:ProgramFilesDockerdocker-compose.exe然后测试一下:docker-compose --version

Linux中:

下载docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

给予执行权限

sudo chmod +x /usr/local/bin/docker-compose

测试命令

$ docker-compose --versiondocker-compose version 1.23.2, build 1110ad01已禁用此文档中的部分内容
