docker在docker中的docker内部撰写 [英] docker compose inside docker in a docker

问题描述

我对Docker来说还很陌生，并且正在此处中找到文档，并尝试部署使用docker-compose 1.14.0在dind内部的几个容器我得到以下内容

I am pretty new to docker and was following the documentation found here, trying deploy several containers inside dind using docker-compose 1.14.0 I get the following

docker run -v /home/dudarev/compose/:/compose/ --privileged docker:dind /compose/docker-compose
/usr/local/bin/dockerd-entrypoint.sh: exec: line 21: /compose/docker-compose: not found

我错过了什么吗？

推荐答案

在执行docker run之前将docker-compose安装添加到Dockerfile中。

Add docker-compose installation to your Dockerfile before executing docker run.

例如，如果您有Ubuntu Docker，则将其添加到 Dockerfile ：

For example, if you have an Ubuntu docker, add to your Dockerfile:

RUN aptitude -y install docker-compose
RUN ln -s /usr/local/bin/docker-compose /compose/docker-compose

因为看起来像您的入口点在/ compose文件夹中查找docker compose，而docker-compose安装在/ usr /

Because it looks like if your entry-point looks up docker compose in /compose folder, while docker-compose is installed in /usr/local/bin by default.

如果要使用具体的docker-compose版本（例如1.20.0-rc2）：

If you want a concrete docker-compose version (for example 1.20.0-rc2):

RUN curl -L https://github.com/docker/compose/releases/download/1.20.0-rc2/docker-compose-`uname -s`-`uname -m` -o /compose/docker-compose
RUN chmod +x /compose/docker-compose
