如何在Docker容器中安装Docker？

本文介绍了如何在Docker容器中安装Docker？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

这是我的Dockerfile：

FROM golang ＃RUN cat / etc / * release 运行apt-get更新运行apt-get -y安装apt-transport-https ca证书curl gnupg2 software-properties-common RUN curl -fsSL download.docker/linux / debian / gpg | apt-key add-运行add-apt-repository deb [arch = amd64] download.docker/linux/debian $ {lsb_release -cs）稳定 运行apt-get更新运行apt-get -y安装docker-ce 运行docker run hello-world

golang Dockerfile是官方的，它基于

Debian GNU / Linux 8（jessie ）

所以我通过检查 Docker Install Tutor（Debian）

但是输出是

步骤8/8：运行docker run hello-world --->在b183b8cc5d10 docker中运行：无法以 unix：///var/run/docker.sock连接到Docker守护程序。泊坞窗守护程序正在运行吗？ 请参阅 docker run --help。

如何解决此问题？我想在主机docker容器中建立docker容器。图片。要解决这个问题：

首先删除以下行：从您的 Dockerfile

最简单的方法是通过使用 -v 标志绑定安装或安装来公开Docker套接字使用 Docker Compose ：

docker run的卷-v /var/run/docker.sock:/var/run/docker.sock ...

This is my Dockerfile:

FROM golang # RUN cat /etc/*release RUN apt-get update RUN apt-get -y install apt-transport-https ca-certificates curl gnupg2 software-properties-common RUN curl -fsSL download.docker/linux/debian/gpg | apt-key add - RUN add-apt-repository "deb [arch=amd64] download.docker/linux/debian $(lsb_release -cs) stable" RUN apt-get update RUN apt-get -y install docker-ce RUN docker run hello-world

The golang Dockerfile is official, it bases on the

Debian GNU/Linux 8 (jessie)

So I wrote down this Dockerfile by checking the install steps from Docker Install Tutor(Debian)

But the output is

Step 8/8 : RUN docker run hello-world ---> Running in b183b8cc5d10 docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. See 'docker run --help'.

How to solve this problem? I want to establish docker containers in the host docker container.

解决方案

I had a similar problem trying to install Docker inside a Bamboo Server image. To solve this:

first remove the line: RUN docker run hello-world from your Dockerfile

The simplest way is to just expose the Docker socket, by bind-mounting it with the -v flag or mounting a volume using Docker Compose:

docker run -v /var/run/docker.sock:/var/run/docker.sock ...
