Install vim in node Docker image

Question

I'm trying to install vim in my image. I'm using node as base image:

FROM node

RUN apt-get update & apt-get install vim

//more things...

I get this error:

E: Unable to locate package vim

Answer 1

You are only using a single ampersand (&) in your RUN directive, which runs a command in the background in bash. Change it to include two ampersands (&&). Please also notice the -y (automatic yes to prompts) I have added to the apt-get statement, without which your docker build command will fail:

RUN apt-get update && apt-get install -y vim
