Hi there!

I'm using Gitlab CI/CD, where I store a private SSH key in CI/CD Variables as a file. That means I can get the path to that file in a variable. The main issue is that the file has the wrong permission for the identity file = 666, I guess.

My current solution is to fix the permission in the task:

set('identity_file', getenv('SSH_KEY'));
set('ssh_arguments', [
    '-o StrictHostKeyChecking=no',
    '-o UserKnownHostsFile=/dev/null',
]);

desc('[CI] Fix SSH key permissions');
task('local:fix-sshkey', function () {
    writeln('Setting permissions 400 for SSH key...');
    runLocally('chmod 400 ' . getenv('SSH_KEY'));
})->once();

I think it could be nice to have it inside the deployer logic and help a little with CI settings. Something like:

set('fix_identity_file_permisssion', true);

What do you think?
