I have been trying to push an image with DOCKER_CONTENT_TRUST=1 without much success, while this used to work until recently. Has anything changed recently? Such as the size of image to get signed, any behavior of the default notary server,…?
$ DOCKER_CONTENT_TRUST_ROOT_PASSPHRASE=xxxxxxxx DOCKER_CONTENT_TRUST_REPOSITORY_PASSPHRASE=xxxxxxxx DOCKER_CONTENT_TRUST=1 docker push xxxxxx/xxxxxx:xxxxxxx
The push refers to repository [docker.io/xxxxxx/xxxxxx]
xxxxxx: digest: sha256:… size: 3693
Signing and pushing trust metadata
failed to sign docker.io/xxxxxx:xxxxxxx: trust server rejected operation.
unable to reach trust server at this time: 504.
