I am trying to setup an automated build on Docker cloud as described here: https://docs.docker.com/docker-cloud/builds/automated-build/#/build-repositories-with-linked-private-submodules
I am using BitBucket as the source repo and created a new public/private key pair. I added the public key to my BitBucket repo (under settings->deployment keys) and my private key as an environment variable (SSH_PRIVATE) to my build. However, the build fails saying
Permission Denied (public key).
Also, when I try to verify my private key under environment variables, it disappears each time I leave the page and comeback despite getting a confirmation/success message when I save.
Not sure what is going on? Any help would be greatly appreciated.
