Authentication
Run hasura locally on top of existing postgres
GraphQL meets Distributed SQL
Create local YugabyteDB cluster
yb-ctl create --rf 3
Connect to ysqlsh
./bin/ysqlsh --echo-queries
Load sample data
Run Hasura on top of newly created Db
docker run -d -p 8080:8080 -e \
HASURA_GRAPHQL_DATABASE_URL=postgres://postgres:@host.docker.internal:5433/yb_demo \
-e HASURA_GRAPHQL_ENABLE_CONSOLE=true hasura/graphql-engine:latest
