Question

添加此内容供其他人参考，因为如果存在这样的答案，它可以节省我10分钟。

我尝试使用ubuntu 14.0LTS virtualbox

安装Docker

sudo apt get install docker

但是，当我尝试运行docker时，它会给我以下错误

The program 'docker' is currently not installed. You can install it by typing: sudo apt-get install docker

为什么ubuntu没有看到docker？

Answer 1

Ubuntu软件包docker实际上是指一个GUI应用程序，而不是我们想要寻找的心爱的DevOps工具。

===更新（感谢@Scott Stensland）===

现在运行以下安装脚本来获取docker：

sudo curl -sSL https://get.docker.com/ | sh

这将运行安装docker的脚本。请注意脚本的最后一部分：

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker stens

Remember that you will have to log out and back in for this to take effect!

更新Docker run：

sudo apt-get update && sudo apt-get upgrade

有关正在进行的更多详情，请参阅下面的docker install documentation或@Scott Stensland的答案

===已过时的答案===

而不是使用docker使用docker.io

即，

sudo apt-get install docker.io

以下解释了为什么它的名字如下： Why install docker on ubuntu should be `sudo apt-get install docker.io`?

Answer 2

重要 - 在ubuntu包上docker是完全不同的（避免它）：

以下问题查看您提及docker的任何软件包

dpkg -l|grep docker

如果仅匹配，则下面没有安装docker是一个不相关的包

docker - KDE3 / GNOME2 docklet应用程序的系统托盘

如果您看到类似于以下的内容，那么您已安装了docker

ii docker-ce 18.06.1~ce~2.1.rc1-0~ubuntu  amd64  Docker: the open-source application container engine

注意 - ubuntu包docker.io没有获得更新（过时不使用）

取而代之的是： 通过执行以下命令在linux上安装最新版本的docker：

  sudo curl -sSL https://get.docker.com/ | sh
# sudo curl -sSL https://test.docker.com | sh  # get dev pipeline version

这是一个典型的输出（ubuntu 16.04）

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker stens

Remember that you will have to log out and back in for this to take effect!

以下是基本的详细安装说明，正如您所看到的那样捆绑在上面的技术中......上面的一个衬垫给出了相同的内容：

https://docs.docker.com/engine/installation/linux/ubuntulinux/

安装完成后，您可以通过发布

来查看已安装的docker软件包

dpkg -l|grep docker

ii  docker-engine                               1.11.2-0~xenial                                     amd64        Docker: the open-source application container engine

现在，当您发出

时，Docker更新将继续安装

sudo apt-get update
sudo apt-get upgrade

看看

 ls -latr /etc/apt/sources.list.d/*docker*
-rw-r--r-- 1 root root 202 Jun 23 10:01 /etc/apt/sources.list.d/docker.list.save
-rw-r--r-- 1 root root  71 Jul  4 11:32 /etc/apt/sources.list.d/docker.list


cat /etc/apt/sources.list.d/docker.list

deb [arch=amd64] https://apt.dockerproject.org/repo ubuntu-xenial main

Answer 3

sudo apt-get install docker

是ubuntu上的一个不同的库。

使用sudo apt-get install docker.io安装正确的泊坞窗。

Answer 4

设置存储

对于Ubuntu 14.04 / 16.04 / 16.10 / 17.04：

sudo add-apt-repository "deb [arch=amd64] \
     https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

对于Ubuntu 17.10：

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable"

添加Docker的官方GPG密钥：

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

然后安装

$ sudo apt-get update && sudo apt-get -y install docker-ce

Answer 5

使用sudo运行您的Docker命令：

sudo docker <your command>

正如documentation所说：

docker守护程序绑定到Unix套接字而不是TCP端口。默认情况下，Unix套接字由用户root拥有，而其他用户只能使用sudo访问它。 docker守护程序始终以root用户身份运行。

如果您在使用docker命令时不想使用sudo，请创建   一个名为docker的Unix组，并向其添加用户。当docker守护进程时   启动时，它使得Unix套接字的所有权可以被读取/写入   码头工人组。

即使安装了apt-get，也找不到docker命令
