Spin-up an ephemeral docker instance.

docker pull openfga/openfga && docker run -p 8080:8080 -p 8081:8081 -p 3000:3000 openfga/openfga run

In another terminal, create a store.

fga store create --name "FGA Demo Store"

Make note of your store ID for use in following commands, for example:

export STORE_ID=01J7MBWN53GQ7PD1JKFEBE83NQ

Write the model.

fga --store-id=$STORE_ID model write --file model.fga

Write a tuple for jack.

fga tuple write --store-id=$STORE_ID user:jack owner document:foobar

And perform some checks for jack, noting that because he is an owner he's also a writer and editor.

fga query check --store-id=$STORE_ID user:jack owner document:foobar
fga query check --store-id=$STORE_ID user:jack writer document:foobar
fga query check --store-id=$STORE_ID user:jack reader document:foobar

Write a tuple for jane.

fga tuple write --store-id=$STORE_ID user:jane reader document:foobar

And perform some checks, noting that she's only a reader.

fga query check --store-id=$STORE_ID user:jane owner document:foobar
fga query check --store-id=$STORE_ID user:jane writer document:foobar
fga query check --store-id=$STORE_ID user:jane reader document:foobar
