Node.JS exec git command error: Permission denied (publickey)

Question

Question: How can I run git push from node.js with passphrase.

I'm trying to build a small module where I need to run git push from node.js to a remote repo, but I'm getting an error when I with from node.js exec but not from the terminal.

My code.

./command.ts

import * as util from 'util';

const exec = util.promisify(require('child_process').exec);

export default function command(command: string): Promise<string> {
  return exec(command, {cwd: process.cwd()}).then((resp) => {
    const data = resp.stdout.toString().replace(/[\n\r]/g, '');
    return Promise.resolve(data);
  });
}

./index.ts

import command from './command';

async function init() {
 try {
  await command('git add .');
  await command('git commit -m "my commit" ');
  conat result = await command('git push');
 } catch (e) {
  console.log(e);
 }
}

init();

and when I run ts-node ./index.ts I get the following error.

Error: Command failed: git push                                                                                                         
git@hostname.org: Permission denied (publickey).                                                                                       
fatal: Could not read from remote repository.                                                                                           

Please make sure you have the correct access rights                                                                                     
and the repository exists.

But when I run git push from the terminal I get prompt with the passphrase and it works.

Any idea on how to solve this issue, is there a way to run git push with passphrase using node.js?

bear in mind that I will love to fix this without any external libs.

Thanks in advance.

In case you are okay with using username and password you could easily do `git push https://username:password@myrepository.biz/file.git --all` — Jiby Jose, Feb 23 '18 at 04:46

As described here, check if the same program works when:

ssh-agent is launched
your key is ssh-add'ed

Not only the prompt should no longer query for your passphrase (now cached by the agent), but your script might benefit from that cache as well.

Thanks for your response, it works however if the there is no ssh key the user will be prompt with the username and pass – diegoddox Feb 23 '18 at 11:03
@diegoddox Well yes... but in your case, there is an ssh key, right? – VonC Feb 23 '18 at 12:16
I do but the people that I will be handed over the module may not have, the best will be if the `exec` could prompt the `passphrase/user:pass` in case of need. – diegoddox Feb 23 '18 at 12:31

@diegoddox Then an https URL might be better: they can cache their own credentials. – VonC Feb 23 '18 at 12:34

You may need to add env: process.env to your exec() options if your key is loaded into an ssh-agent process. There are some environment variables ssh-agent exports that other processes use to find ssh-agent to access its keys.
