I am testing some Bitcoin related code and in order to test it have installed bitcoin-testnet-box within a docker container.

I use this guide: https://registry.hub.docker.com/u/freewil/bitcoin-testnet-box/

I pulled and run the docker without any problems.

BUT, I can not edit the bitcoin.conf files in their directories because I dont have an editor like NANO installed.

I would like to do:

sudo apt-get install nano

But it's not working. How can I fix that?

You can create your own Dockerfile to build on freewil/bitcoin-testnet-box

Dockerfile

FROM freewil/bitcoin-testnet-box
MAINTAINER dude
USER root
RUN apt-get update && apt-get install nano

In the directory with your Dockerfile run:

docker build -t "mybitcoinimage" .

and start the container

docker run -it mybitcoinimage /bin/bash

And you are in with root access and nano.
