ERROR: manifest for hyperledger/fabric-orderer:latest not found

1. In docker command

# pull to local before using it
docker pull hyperledger/fabric-orderer:x86_64-1.0.0-rc1
# rename it to 'latest'
docker tag hyperledger/fabric-orderer:x86_64-1.0.0-rc1 hyperledger/fabric-orderer:latest

2. Recommended: specify tag in docker compose file

Please try to find the docker-compose file used in network_setup.sh.

If you are using 1.0beta, it should be docker-compose-cli.yaml

In docker-compose-cli.yaml if you see:

extends:
file: base/docker-compose-base.yaml

then in base/docker-compose-base.yaml if you see this:

...
image: hyperledger/fabric-orderer
...

change it to be

image: hyperledger/fabric-orderer:x86_64-1.0.0-rc1

This fix is recommended also applied to fabric-peer, fabric-ca setting in base/docker-compose-base.yaml for alignment.

EDIT The problem no longer exists. Now the default latest tag will be provided by fabric team.
