Is it safe to use shared gitlab runner provided by gitlab instance?

image: docker:latest

  • docker:dind
  • build
    Preparing the “docker+machine” executor

Hi all,
Here i am trying to build docker image on shared runners using gitlab instance,
my query is , is it safe to use shared gitlab runners for building docker images.?
why i am getting this warning ( level=warning msg=“Binding to an IP address, even on localhost, can also give access to scripts run in a browser. Be safe out there!” host=“tcp://” ).
please share your suggestions, whether to use to shared runners for production ??
