Cardano-graphql instance running in a kubernetes cluster returns blank error page at `http://localhost:3100/graphql`

Red3nzo commented 2 years ago

Summary

I'm running a cardano stack inside a Kind kubernetes cluster. The stack consists of the following containers with these images

CARDANO_NODE: inputoutput/cardano-node:1.35.0
CARDANO_DB_SYNC: inputoutput/cardano-db-sync:13.0.0
HASURA_CLIENT: inputoutput/cardano-graphql-hasura:6.2.0
CARDANO_GRAPHQL: inputoutput/cardano-graphql:6.2.0-testnet
CUSTOM_BACKEND: An in house image

The error persists within the inputoutput/cardano-graphql:6.2.0-testnet container; the container logs this information at first launch & everything I restart it which seems normal to me

{"name":"cardano-graphql","hostname":"cardano-graphql-testnet-9dc5fb75b-zlsf9","pid":1,"level":30,"module":"Server","msg":"Initializing","time":"2022-07-15T23:03:45.457Z","v":0}

The pod.yml file looks like this for the cardano-graphql configuration

        - name: cardano-graphql-testnet

                path: postgres_password
            secretName: postgres-chaindb-secrets

Once I run said container & reach the browser I get nothing, blank page & infinite loading the browser tab at the top of the browser. The page shows this error This page isn’t working; localhost didn’t send any data. ERR_EMPTY_RESPONSE

EDIT: Running the following curl returns this message curl: (52) Empty reply from server

curl -X POST \                                                                                                           
         -H "Content-Type: application/json" \
         -d '{"query": "{ cardano { tip { number slotNo epoch { number } } } }"}' \
         http://localhost:3100/graphql

Steps to reproduce the bug

Deploy inputoutput/cardano-graphql:6.2.0-testnet image into a kubernetes pod after cardano-node, cardano-db-sync & 'postgres' have been setup
Go to http://localhost:3100/graphql and see a error page that says This page isn’t working; localhost didn’t send any data. ERR_EMPTY_RESPONSE

Actual Result

error page that says This page isn’t working; localhost didn’t send any data. ERR_EMPTY_RESPONSE & an infinite loading bar inside the tab in the browser

Expected Result

To see the graphql console at http://localhost:3100/graphql

It's getting stuck trying to apply the Hasura migrations or metadata. See if the debug logs reveal any more hints:

            - name: LOGGER_MIN_SEVERITY

Just saw this sorry for late reply, I've built a custom image of the master branch due to the fact my cardano-node was at 1.35.0 & cardano-db-sync at 13.0.0. I added the LOGGER_MIN_SEVERITY env & I'm currently getting this error. Should I switch my graphql image back to 6.2.0-testnet instead of building from master?

================================
 Missing environment variables:
    loggerMinSeverity: undefined

 Exiting with error code 1
================================

I'm a but confused because I have added this env before
