I only get one CID, why do I get multiple CIDs?

Hi, I have installed ipfs clister in kebernetes.
I have uploaded an image with REST Api /aa call. I get this as response:

In my nextJs app I make an axios call:

         // to read the file
        const fileStream = fs.createReadStream(filePath);
        const metadata = {
            name: fields['name'],
            description: fields['description'],
            image: fileStream,
            attributes: [{
                trait_type: "Version",
                value: "1.0"
            }, {
                trait_type: "marketplace",
                value: "ART"
            }],
        };
   
        //Upload NFT to IPFS & Filecoin
        const response = await axios.post(IPFS_CLUSTER_RESTAPI_URL + '/add', metadata, {
            headers: {
                'Content-Type': 'multipart/form-data'
            },
        });

You get multiple CIDs like that when you upload multiple files through a single multipart request to /add. The last one is usually the “root” cid.

I believe that you are uploading the metadata as “form-data” in your POST, and thus making a request with multiple parts.

Cluster-pin metadata in cluster /add endpoint goes as part of the query params to the request (i.e. ?name=myname&meta-description=desc&meta-attributes=a,b,c). Note that metadata field names must be prepended by “meta-”.

See:

igorroman777 · November 5, 2024, 9:27pm

Yes, I use the metadata as ‘form-data’ in my POST call.
I don’t see anything about root-CID, all CID are the same.
How do I get only one CID?

hector · November 5, 2024, 9:33pm

Don’t use the metadata as form-data as this is equivalent to adding multiple files, and so you get one CID per file.

igorroman777 · November 5, 2024, 9:47pm

ok, that means don’t use multipart/form-data.
How do I send the image file?

igorroman777 · November 5, 2024, 10:06pm

ohne multipart/form-data bekomme ich einen Fehler:
Anfrage fehlgeschlagen mit Statuscode 400

hector · November 5, 2024, 10:38pm

It’s explained in the docs I sent.

igorroman777 · November 11, 2024, 8:01am

Hi @hector ,
Thank you, now I only get a CID. But I still had to use form-data:

const metadata = JSON.stringify({
            "meta-name": fields['name'],
            "meta-description": fields['description'],
            "meta-file": fs.createReadStream(filePath),
            "meta-attributes": [{
                trait_type: "Version",
                value: "1.0"
            }, {
                trait_type: "marketplace",
                value: "ARTWISTA"
            }],
        });

formData.append("meta-data", metadata);
        //Upload NFT to IPFS & Filecoin
        const response = await axios.post(IPFS_CLUSTER_RESTAPI_URL + '/add', 
            formData, {
            maxBodyLength: Infinity,
            headers: {
              'Content-Type': `multipart/form-data;`,
              // Authorization: `Bearer ${JWT_SECRET_IPFS_CLUSTER}`
            }
          });

One more question, now i want to use IPFS gateway local in kubernetes:

Curl 
http://10.43.90.35:8080/ipfs/QmVmrV76aiVcULqGQfH8kYkQXzhpvtVYy9e7hAQXjt4AaQ

But no answer there. Do you have an idea?

hector · November 11, 2024, 8:39am

In this case it seems you are uploading a json with embedded binary data, which I’m not sure is the best (should probably base64 it first).

Possibly your gateway is only listening on localhost and you need to change Addresses.Gateway to use 0.0.0.0 .

igorroman777 · November 11, 2024, 12:54pm

Thanks @hector ,

yes, a json is uploaded
yes, my service mapped to localhost:

Gateway server listening on /ip4/127.0.0.1/tcp/8080
Daemon is ready

These commands in the script do not seem to work:

ipfs config --json Addresses.Gateway /ip4/0.0.0.0/tcp/8080

hector · November 21, 2024, 5:10pm

what script? Where did you find that command?

igorroman777 · November 21, 2024, 8:17pm

apiVersion: v1
kind: ConfigMap
metadata:
  name: ipfs-cluster-set-bootstrap-conf
  namespace: ipfs-cluster
data:
  entrypoint.sh: |
    #!/bin/sh
    user=ipfs
    sleep 10
    # This is a custom entrypoint for k8s designed to connect to the bootstrap
    # node running in the cluster. It has been set up using a configmap to
    # allow changes on the fly.
