Fetching files from IPFS-cluster using CID

[trinayanbhatt]

Hi Team,

I'm working with a private IPFS cluster and want to fetch files using CIDs.

Like IPFS nodes provides cat and get functionality, we are not able to get similar commands or API while using IPFS cluster client.

So, can someone please help how can we use cluster client for fetching data from IPFS cluster nodes using CID.

Cluster daemon only orchestrates pinning and adding. Retrieval is supposed to be done over the IPFS protocol or the IPFS gateway, which both are things provided by the IPFS daemon itself, thus not provided by cluster.

This is a common ask though. I will leave it open for future work with the following thoughts:

• REST-API could offer a GET endpoint to fetch content
• Equivalent to IPFS cat, except:
  • Only works for content pinned in the cluster
  • Chooses one of the allocations of the pin and essentially proxies to IPFS cat
• Cat is a unixfs command and therefore limited to unixfs content types. Approach could be extended to dag/get for general IPLD fetching. (or block/get and let users parse ipld themselves)
