Use drone.io to build.
You'll need to install the Drone CLI:
https://docs.drone.io/cli/install/
I'm using drone version 1.2.1.
Create a secrets.yml in the root:
docker_password: "00000000-0000-0000-0000-000000000000 "
Run Drone Docker image build:
drone exec --pipeline docker --secret-file secrets.yml
