Error: got unexpected status: BAD_REQUEST -- Unknown consortium name: DocChain
Usage:
  peer channel create [flags]

Flags:
  -c, --channelID string   In case of a newChain command, the channel ID to create.
  -f, --file string        Configuration transaction file generated by a tool such as configtxgen for submitting to orderer
  -t, --timeout int

Answer 1

Firstly, replace DocChain with DocChainConsortium.

Then run:

docker-compose -f docker-compose-cli.yaml down --volumes --remove-orphans

This should work
