Data import: issues with `dgraph live` into a docker-compose deployment

Issues Dgraph

Trying to import an RDF into a shuri docker-compose deployment. I checked that localhost:9080 is indeed accessible. My docker-compose file is pretty vanilla.

Command:

docker run dgraph/dgraph:shuri dgraph live -f export/dgraph.r10176.u0812.1442/g01.rdf.gz

Results:

Not sure what is in your docker-compose. But in general you have to use the container name as part of the URI. Try to use like this.

docker run dgraph/dgraph:shuri \
dgraph live -a alpha:9080 -z zero:5080\
-f export/dgraph.r10176.u0812.1442/g01.rdf.gz

But this command feels odd. Are you sure that dgraph.r10176.u0812.1442/g01.rdf.gz will be there? is this a new container or part of the docker-compose? if part of it, you should use docker exec instead.

Thanks Michael. Yeah, docker run command was incorrect. The issue was not having the -a and -z flags in the docker exec call.

For those finding this via search here are the steps I use to import an RDF into a running cluster:

docker cp export/dgraph.r10176.u0812.1442/g01.rdf.gz services_zero_1:/tmp/
docker exec services_zero_1 dgraph live -a alpha:9080 -z zero:5080 -f /tmp/g01.rdf.gz

Note that services_zero_1 is the container name of the zero container in my deployment, started with this command dgraph zero --my=zero:5080.
