如何编辑文件？

推荐答案

与评论一样，没有默认的编辑器 - 奇怪 - code> $ EDITOR env变量为空。您可以通过以下方式登录到容器中：

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

docker exec -it <container> bash

并运行：

apt-get update
apt-get install vim

或使用以下Docker文件：

or use the following Dockerfile:

FROM  confluent/postgres-bw:0.1

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

编辑

Docker图像被传递修剪到最低限度 - 所以没有编辑器发货集装箱这就是为什么需要手动安装。

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