I am trying to follow the Dgraph DQL Tour tutorial.
I have done
docker pull dgraph/standalone
docker run -it -p 5080:5080 -p 6080:6080 -p 8080:8080 \
-p 9080:9080 -p 8000:8000 -v ~/dgraph:/dgraph --name dgraph \
dgraph/standalone:v21.03.0
at step 2.
However, at step 3 Load Schema | Intro | Dgraph Tour
I got error:
Error: Is Dgraph running locally? or reachable? TypeError: Failed to fetch
Here is my terminal log:
