Thank you! I’ve gotten stuck with the tutorial and this command
docker run --rm -it -p 8000:8000 -p 8080:8080 -p 9080:9080 dgraph/standalone:v21.12.0
But thank to you, I updated the command to
docker run --rm -it -p 8000:8000 -p 8080:8080 -p 9080:9080 dgraph/standalone:v20.11.3
now I have dgraph UI at my localhost:8000. Really appreciate it!
