Shell到Docker容器后如何编辑文件？ [英] How do I edit a file after I shell to a Docker container?

问题描述

我使用以下命令成功地炮击了Docker容器：

I successfully shelled to a Docker container using:

docker exec -i -t 69f1711a205e bash

现在我需要编辑文件，而且内部没有任何编辑器：

Now I need to edit file and I don't have any editors inside:

root@69f1711a205e:/# nano
bash: nano: command not found
root@69f1711a205e:/# pico
bash: pico: command not found
root@69f1711a205e:/# vi
bash: vi: command not found
root@69f1711a205e:/# vim
bash: vim: command not found
root@69f1711a205e:/# emacs
bash: emacs: command not found
root@69f1711a205e:/#

如何编辑文件？

推荐答案

与注释中一样，未设置默认编辑器-奇怪- $ EDITOR 环境变量为空。您可以使用以下命令登录到容器：

As in the comments, there's no default editor set - strange - the $EDITOR environment variable is empty. You can log in into a container with:

docker exec -it <container> bash

然后运行：

apt-get update
apt-get install vim

或者使用以下Dockerfile：

Or use the following Dockerfile:

FROM  confluent/postgres-bw:0.1

RUN ["apt-get", "update"]
RUN ["apt-get", "install", "-y", "vim"]

已将Docker映像修剪到最低限度-因此，随发货的容器未安装任何编辑器。这就是为什么需要手动安装它的原因。

Docker images are delivered trimmed to the bare minimum - so no editor is installed with the shipped container. That's why there's a need to install it manually.
