"Host key verification failed." when using rsync

[ograr]

This seems to be a slightly different issue than #16 or #2 so I'm making a new one, hope that's ok. My current setup (with SSH_KNOWN_HOSTS) seems to work fine just up until Deployer tries to rsync to the server.

Perhaps the problem is that SSH_PRIVATE_KEY isn't exposed to the rsync over SSH tunnel? Or am I doing something wrong?

Below is my setup, inspired by https://atymic.dev/blog/github-actions-laravel-ci-cd/.

deploy.php:

<?php
namespace Deployer;

require 'recipe/common.php';
require 'recipe/rsync.php';

// Project name
set('application', 'SECRET');

set('allow_anonymous_stats', false);

// Hosts
$hosts = ['dev' => 'staging', 'prod' => 'production'];
foreach ($hosts as $host => $stage) {
  host($host)
    ->hostname(getenv('SSH_HOST'))
    ->port(getenv('SSH_PORT'))
    ->stage($stage)
    ->user(getenv('SSH_USER'))
    ->set('deploy_path', getenv('DEPLOY_PATH'));
}

// Tasks
task('deploy', [
    'deploy:info',
    'deploy:prepare',
    'deploy:release',
    'rsync',
    'deploy:symlink',
    'cleanup',
    'success'
]);

deploy.dev.yml:

name: Deploy to dev

on:
  push:
    branches: develop

jobs:
  deploy:
    name: Deploy to dev
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/develop'
    steps:
      - uses: actions/checkout@v2
      - name: Setup PHP
        uses: shivammathur/setup-php@v2
        with:
          php-version: 7.4
      - name: Install Deployer
        uses: atymic/deployer-php-action@master
        with:
          ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}
          ssh-known-hosts: ${{ secrets.SSH_KNOWN_HOSTS }}
      - name: Get Deployer version
        run: dep -V
      - name: Deploy to dev
        run: dep deploy dev -vvv
        env:
          SSH_HOST: ${{ secrets.DEV_SSH_HOST }}
          SSH_PORT: ${{ secrets.DEV_SSH_PORT }}
          SSH_USER: ${{ secrets.DEV_SSH_USER }}
          DEPLOY_PATH: ${{ secrets.DEV_DEPLOY_PATH }}

I just discovered that I forgot to set this in my deploy.php:

set('rsync_src', function () {
    return __DIR__;
});

Hence the strange rsync source in the log above. Still not working though (still getting the "Host key verification failed." error).
I've also tried running the same rsync command locally after adding my private key with ssh-add and that works as expected.
Is this perhaps a problem with https://github.com/deployphp/deployer?

rsync works if I'm doing this in my Github Action instead:

name: Deploy to dev

on:
  push:
    branches: develop

jobs:
  deploy:
    name: Deploy to dev
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/develop'
    steps:
      - uses: actions/checkout@v2
      - name: Setup PHP
        uses: shivammathur/setup-php@v2
        with:
          php-version: 7.4
      - name: Install SSH key
        uses: shimataro/ssh-key-action@v2
        with:
          key: ${{ secrets.SSH_PRIVATE_KEY }}
          known_hosts: ${{ secrets.SSH_KNOWN_HOSTS }}
      - name: Install Composer dependencies
        run: composer install --prefer-dist --no-interaction --no-progress
      - name: Get Deployer version
        run: vendor/bin/dep -V
      - name: Deploy to dev
        run: vendor/bin/dep deploy dev -vvv
        env:
          SSH_HOST: ${{ secrets.DEV_SSH_HOST }}
          SSH_PORT: ${{ secrets.DEV_SSH_PORT }}
          SSH_USER: ${{ secrets.DEV_SSH_USER }}
          DEPLOY_PATH: ${{ secrets.DEV_DEPLOY_PATH }}

That is, I'm using https://github.com/shimataro/ssh-key-action to install the SSH key and "local" composer version of Deployer.

My current conclusion is that atymic/deployer-php-action somehow isn't exposing the SSH key and/or known hosts for rsync.

The same error when I try to use the upload function.

task('upload:assets', function () {
    upload('public/', '{{release_path}}/public');
});
