GraphQL queries with cURL

---

NOTE: In the Causemos stack, it is much simpler to interact with the request-queue.

See the Causemos Confluence for more info.

Prefect documentation here
To write your own query with curl just replace the GraphQL query in the query variable and leave the rest of the bash dark magic alone.
NOTE: You will need to double escape \\" any quotes that appear inside a JSON string (like the parameters in the first query.)
To craft GraphQL queries you can use the Interactive API tab in the Prefect UI where you have full access to the schemas and type information

Sample queries

Start a new flow run

query='mutation {
  create_flow_run(input: {
    flow_id: "2c362d3d-f087-4004-9d2c-7a7b8deec9b0",
    flow_run_name: "<optional name of run>",
    parameters: "{\\"model_id\\": \\"e0a14dbf-e8e6-42bd-b908-e72a956fadd5\\", \\"run_id\\": \\"749916f0-be24-4e4b-9a6c-798808a5be3c\\" }"
  }) {
    id
  }
}'
query="${query//[$'\n']}"
curl 'http://10.65.18.57:4200/' -H 'Content-Type: application/json' -d '{"query":"'"${query//[\"]/\\\"}"'"}'

NOTE: The flow_id of a flow changes with each version. To create a "stable" query that continues to work between flow updates use the flow's version_group_id instead.

Check the state of a flow run

query='query {
  flow(where: { id: {_eq: "<Set flow_id here>"} }) {
    name
    flow_runs(where: { id: {_eq: "<flow_run_id returned from start mutation>"}}) {
      state
      start_time
      end_time
    }
  }
}'
query="${query//[$'\n']}"
curl 'http://10.65.18.57:4200/' -H 'Content-Type: application/json' -d '{"query":"'"${query//[\"]/\\\"}"'"}'

Get the logs of a flow run

query='query {
  flow(where: { id: {_eq: "<Set flow_id here>"} }) {
    name
    flow_runs(where: { id: {_eq: "<flow_run_id returned from start mutation>"}}) {
      state
      start_time
      end_time
      logs(order_by: {timestamp: asc}) {
        timestamp
        level
        message
      }
    }
  }
}'
query="${query//[$'\n']}"
curl 'http://10.65.18.57:4200/' -H 'Content-Type: application/json' -d '{"query":"'"${query//[\"]/\\\"}"'"}'
