Answer 1

1. Check if docker login is working. If not,

   docker-machine ssh default
   sudo vi /etc/resolv.conf
   

   change nameserver to 8.8.8.8

2. Using composer-cli at v0.19.5 Add this in fabric-scripts\hlfv11\createPeerAdminCard.sh

   CYGDIR="$(cygpath -pw "$DIR")"
   if [[ ! -v DOCKER_HOST ]]; then
   echo "DOCKER_HOST is NOT set <<<< Please set the env for Docker !!!!"
   DOCKER_IP="localhost"
   else
   DOCKER_IP="${DOCKER_HOST:6}"
   INDEX=`expr index "${DOCKER_IP}" :`
   echo $INDEX
   DOCKER_IP="${DOCKER_IP:0:(INDEX-1)}"
   fi
   echo  "Using the Docker VM IP Address: ${DOCKER_IP}"
   

   And replaced every localhost in the file with $DOCKER_IP

Make sure docker is running

From their documentation, Installing pre-requisites

Docker is required.

Then try docker ps, check if the peer node/s is listed.

Then try to ping your network with composer network ping --card admin@<some_network>
