I was running an older version of dgraph standalone docker and it worked fine. Recently I have updated to the newest version and I haven’t been able to use it. After some searching, I have discovered that the ratel service was no longer available inside this docker.
This change hasn’t been mentioned anywhere, even on the getting started page it is stated:
This would start a single container with Dgraph Alpha , Dgraph Zero and Ratel running in it. You would find the Dgraph data stored in a folder named dgraph of your home directory .
I was able to find the solution only after searching here.
Please update the documentation, thanks
