How to backup root-ca-only from UCP replica

Question

I am trying to backup UCP master root-ca-only from UCP replica server:

docker run --rm -i --name ucp -v /var/run/docker.sock:/var/run/docker.sock docker/ucp:1.1.0 backup --root-ca-only --id 4G26:AMCX:67XR:TIKD:CXYS:3PKD:5O66:SKZM:T22Q:OYYL:BV2H:QJ3D --url https://ucp-master-url > backup.tar 

It is not working. Please suggest the correct way.

Answer 1

Can you try the interactive mode like this:

docker run --rm -i --name ucp -v /var/run/docker.sock:/var/run/docker.sock docker/ucp backup --root-ca-only --passphrase "secret" > backup.tar -i

I am getting time="2016-06-17T00:51:17Z" level=fatal msg="flag provided but not defined: -url" with --url. You can pass the fingerprint with --id xxx like you did, just don't use the --url.
