如何扩展现有泊坞窗图像？ [英] How to extend an existing docker image?

问题描述

我正在使用官方弹性搜索Docker图片，而不是设置我的自己的弹性搜索实例。而且，这样做很棒，直到我想延长它的时候。我想将奇迹安装到ElasticSearch实例中以获取更多信息。

I'm using the official elasticsearch Docker image instead of setting up my own elastic search instance. And that works great, up to the point when I wanted to extend it. I wanted to install marvel into that ElasticSearch instance to get more information.

现在dockerfile / elasticsearch自动运行ElasticSearch并将命令设置为 / bin / bash 不起作用，附加到容器或尝试通过SSH访问它，也不要使用 apt-get install -y openssh-server 安装ssh-daemon。

Now dockerfile/elasticsearch automatically runs ElasticSearch and setting the command to /bin/bash doesn't work, neither does attaching to the container or trying to access it over SSH, nor installing ssh-daemon with apt-get install -y openssh-server.

在这种特殊情况下，我可以进入容器的文件系统并执行 opt / elasticsearch / bint / plugin -i elasticsearch / marvel /最新的和一切工作。

In this particular case, I could just go into the container's file system and execute opt/elasticsearch/bint/plugin -i elasticsearch/marvel/latest and everything worked.

但是，如何安装需要安装的附加服务， apt-get 当我不能在运行容器中有终端时

But how could I install an additional service which needs to be installed with apt-get when I can't have a terminal inside the running container?

推荐答案

只需使用Docker文件以

Simply extend it using a Dockerfile that start with

FROM dockerfile/elasticsearch

并安装marvel或ssh-server或任何您需要的。然后，以正确的命令结束启动您的服务。您可以使用主管启动多种服务，请参阅运行在Docker容器中自动进行服务，以获取更多信息。

and install marvel or ssh-server or whatever you need. Then, end with the correct command to start your services. You can use supervisor to start multple services, see Run a service automatically in a docker container for more info on that.
