Docker container cannot clone public Github repo

Question

I am guessing this is an internet connectivity issue, however, there might be some RSA public key missing.

I have this Dockerfile:

FROM node:4-onbuild
COPY test-install-post-publish.sh /usr/src/app/
EXPOSE 8888

The bash script that gets COPY'ed into the container looks like:

#!/usr/bin/env bash

cd # cd to home dir
mkdir suman-test
cd suman-test &&
rm -rf suman-test-projects &&
git clone git@github.com:sumanjs/suman-test-projects.git &&
cd suman-test-projects &&
./test-all.sh

I run the container, and I get this:

npm info it worked if it ends with ok
npm info using npm@2.15.11
npm info using node@v4.6.2
npm info prestart installation@1.0.0
npm info start installation@1.0.0

> installation@1.0.0 start /usr/src/app
> ./test-install-post-publish2.sh

Cloning into 'suman-test-projects'...

So it looks like the container can "connect to the internet", but it is barfing because it doesn't have the RSA information it needs. BUT this is a public repo! Why is Github asking for SSH keys and stuff?

Anyone know what might be happening? How to fix? I am certain this is a public Github repo, you could see for yourself if you want.

Answer 1

Perhaps I should just use HTTPS instead of SSH ?

Yes, if you didn't add the ssh key.

But still, why the above?

You need to add your public key to GitHub in order to clone through SSH -- even if it is a public repo. Why? Because git needs to authenticate though SSH to GitHub's servers in order to do the clone. And in order to do that, they need to have your public key.
