Docker-Compose issue transient failure

Users
1

Hello and thanks for your work.

I’m trying to follow the tutorial, especially the https://docs.dgraph.io/get-started/#docker-compose section.

I copy/pasted the docker-compose mentioned in the documentation, but when running it, I get the following error :
server_1 | 2018/06/19 12:02:25 pool.go:158: Echo error from zero:5080. Err: rpc error: code = Unavailable desc = all SubConns are in TransientFailure

And when I’m trying to follow along with the tutorial (the POST request), I get the following error :

{
    "errors": [
        {
            "code": "ErrorInvalidRequest",
            "message": "Please retry again, server is not ready to accept requests"
        }
    ],
    "data": null
}

Any idea of what I’m doing wrong ? I don’t think I missed any step in the docs. It sounded pretty straightforward to just copy/paste the docker-compose, then docker-compose up. Am I missing something ?

Thanks a lot for your help.

Hard to tell, try delete the P, W, Z folders. And try again.

Hello.

What do you mean, deleting the folders ? Because I’m trying to run the docker-compose stuff, not sure which folders you need me to delete ?

Where are these folders (apart within the docker images) ?

Sorry, in case of docker delete volumes related.

Ah OK, thanks for your answer.
I tried the “armaggedon” thing mentionned here : https://stackoverflow.com/questions/34658836/docker-is-in-volume-in-use-but-no-docker-containers to be really really sure my setup was perfectly clean and unfortunately it didn’t change anything.

Maybe a matter of permissions, I don’t know.

This is odd, how is your whole setup?

Mac OS 10.13.3

docker-compose -version
docker-compose version 1.16.1, build 6d1ac21

The “armaggedon” run (so no container, no image, no volume)

Sorry I must be missing something obvious since I’m the only one facing this issue but… I’ve been struggling with this for hours now, and I have absolutely no clue what I’m doing wrong

OK, got it. I upgraded the docker version on my machine and now :

server_1  | 2018/06/19 15:14:13 groups.go:356: Serving tablet for: _predicate_
server_1  | 2018/06/19 15:14:13 mutation.go:158: Done schema update predicate:"_predicate_" value_type:STRING list:true

Looks like I’m good to go with the rest of the tutorial. Thanks for your help and telling me something was wrong, it helped me investigate on docker itself.

Phew.

Nice, I was doing a test https://youtu.be/_nCz689tqEo

Glad you got it fixed!
