1. Run a rqlite node:
docker run -p 4001:4001 rqlite/rqlite2. Create a table and insert a row:
curl -XPOST 'localhost:4001/db/execute?pretty' -H 'Content-Type: application/json' -d '[
"CREATE TABLE foo (id INTEGER NOT NULL PRIMARY KEY, name TEXT)",
"INSERT INTO foo(id, name) VALUES(1, \"fiona\")"
]'3. Query the data:
curl -G 'localhost:4001/db/query?pretty' --data-urlencode 'q=SELECT * FROM foo'Learn how to form a multi-node cluster in seconds. and dive into the Developer Guide.
