Let's run an instance of Dgraph on your machine; that'll give you a handle on installing Dgraph and loading data yourself.
All the data in this tutorial will be stored in the instance you install, and all the queries will look for Dgraph on your local machine. By running it in a container, you'll have a fresh Dgraph that will serve as a sandbox for you to learn and experiment.
There are several ways to install and run Dgraph, all of which you can find in the Download page. For this tutorial, let's run Dgraph in a container with Docker.
First, grab the latest version of Docker.
Then, pull the latest Dgraph version with:
docker pull dgraph/dgraph:v20.03.0
Let's create a folder for storing Dgraph data outside of the container:
mkdir -p ~/dgraph
Now, to run Dgraph in Docker, it's:
# Run Dgraph zero docker run -it -p 5080:5080 -p 6080:6080 -p 8080:8080 \ -p 9080:9080 -p 8000:8000 -v ~/dgraph:/dgraph --name dgraph \ dgraph/dgraph:v20.03.0 dgraph zero # In another terminal, now run Dgraph alpha docker exec -it dgraph dgraph alpha --lru_mb 2048 --zero localhost:5080 # And in another, run ratel (Dgraph UI) docker exec -it dgraph dgraph-ratel
Dgraph Alpha will now be running and listening for HTTP requests on port
8080 and Ratel would be listening on port
There are more options, but that's all we need to get started.
