   docker run \
     --rm \
     -e SONAR_HOST_URL="http://sonarqube:9000" \
     -e SONAR_LOGIN="97cd1f21966042b2320539c1b720144d5e2aaced" \
     -v "$PWD:/usr/src" \
     $(awk '{if(NF>=2){print "--add-host",$2":"$1}}' /etc/hosts) \
     sonarsource/sonar-scanner-cli -Dsonar.projectKey=myproject

   awk '/^[0-9]/ {print "-add-host",$2":"$1}' /etc/hosts

     -v "$PWD:/usr/src" \
     -v /etc/hosts:/etc/hosts \
     sonarsource/sonar-scanner-cli -Dsonar.projectKey=myproject

    

3. --net host
   

   docker run \
     --rm \
     -e SONAR_HOST_URL="http://sonarqube:9000" \
     -e SONAR_LOGIN="97cd1f21966042b2320539c1b720144d5e2aaced" \
