Feeding data in dgraph (step-1 tour/moredata) is crashing

I have no issues with it.

You are probably confusing some step in the process. Please check that the container named “dgraph” is running. Use docker ps, in the field ‘NAMES’ you should see dgraph.

This error is saying that there is no connection to the cluster (Zero + Alpha). Since this step is using the same container, this error should not occur.

This error would only happen in two scenarios.

1 - You are executing the Live load in another container and that means that the dgraph will not be in “localhost”. But in the name of the container for example “zero: 6080, alpha: 9080” or something similar.

2 - Alpha and Zero have not been started.

Test these steps:

  1. docker pull dgraph/dgraph
  2. docker run -it -p 5080:5080 -p 6080:6080 -p 8080:8080 -p 9080:9080 -p 8000:8000 --name dgraph dgraph/dgraph dgraph zero

Note that I have removed the volume binding

  1. docker exec -it dgraph dgraph alpha --lru_mb 2048 --zero localhost:5080
  2. docker exec -it dgraph sh
  3. curl -L -o 1million.rdf.gz "https://github.com/dgraph-io/tutorial/blob/master/resources/1million.rdf.gz?raw=true"
  4. curl -L -o 1million.schema https://raw.githubusercontent.com/dgraph-io/benchmarks/master/data/1million.schema
  5. exit
  6. docker exec -it dgraph dgraph live -f 1million.rdf.gz --alpha localhost:9080 --zero localhost:5080 -c 1 -s 1million.schema

You should see:

docker exec -it dgraph dgraph live -f 1million.rdf.gz --alpha localhost:9080 --zero localhost:5080 -c 1 -s 1million.schema
