Fixing 'Enter passphrase for /dev/fd/63' in a Gitlab CI job If you're a Gitlab user you're probably hoping to use Gitlab CI to automate builds and deployments. You probably want to deploy something using rsync, using an SSH key for security. Unfortunately (in my opinion) the official Gitlab documentation is confusing. While the Gitlab team does provide example .gitlab-ci.yml files that are supposed to work, the actual specifics of what to do are sketchy, and I found myself puzzling over a curious error message: "Enter passphrase for /dev/fd/63" ... WTF?
