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

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.
