Description
Hello,
I'm on centos7 (working with docker engine). I started fiddling with docker-credential-pass in order to be able to do this:
echo pass | docker login private.registry.com --username AWS --password-stdin
ok that's now working. but...
Problem
I use shell script to update docker container on remote vm by azure pipeline,
but when I pull image, it triggers gpg passphrase dialog
docker pull private.registry.com/image

env
centos7
gpg (GnuPG) 2.0.22, libgcrypt 1.5.3
pass version v1.7.4
docker-credential-pass (github.com/docker/docker-credential-helpers) v0.7.0
I want know how to disable the passphrase dialog. Please help me, Thanks.

Research direction
Start by reproducing the docker pull through docker-credential-pass on the listed CentOS 7, GnuPG 2.0.22, pass v1.7.4, and helper v0.7.0 environment. Inspect how the credential helper invokes pass and GPG, then verify whether a supported non-interactive configuration exists; done means documenting or implementing a reliable way to prevent the dialog in the Azure pipeline scenario.
