You can run into odd DNS resolution issues depending on the configuration of DNS on your host system. The easiest thing to try is to add the dns_search config value to your Compose file:

cli:
    container_name: cli
    image: hyperledger/fabric-tools:$IMAGE_TAG
    tty: true
    stdin_open: true
    dns_search: .

See https://stackoverflow.com/a/45916717/6160507 as well ... you might need this for all of your services.

    I try with IP address (localhost and 0.0.0.0 and container IP) but the same error occurs, I think it does not depend on DNS @Gari Singh. – Hashem Jahangiri Feb 02 '20 at 08:38

solution 1 : use the command: sudo echo "nameserver 8.8.8.8" and start once again

Solution 2 : check your container logs and see

use the command "docker logs container-id"

Solution 3 :add "dns_serach: ." in docker-compose.yaml file and start once again as below

** dns_search: . **
