IPFS (InterPlanetary File System)

IPFS Node Setup

• To initialise node:

• To bring node online:

ipfs daemon

File Upload and Retrieval

• Files can be added to IPFS by

ipfs add <filename>

• Example:

• Uploaded file can be retrieved by CID

ipfs get <CID>

Features

• Pinning

  • Files can be pinned by

  ipfs pin add <cid>

  • If you wish to prevent the files from being garbage collected, you need to pin them.

• Mutable links

  • You create an IPNS name linked to your IPFS node's ID by:

  

• Garbage Collection

  • To delete all files except pinned files:

  ipfs repo gc

Application for File Upload and Retrieval

• I created application using Flask and IPFS API for uploding and retrieving file.
• I also dockerised the app with ipfs/go-ipfs iamge and hosted it on AWS E2C.
• I don't have domain names. So I used DuckDNS for DNS services and Lets Encrypt for SSL Certificates.

File access through Public IPFS Gateway

• Once file is uploaded, CID is generated.
• You can view file through public link provided or through the server node itself.

Note : Public URL takes some time (nearly 30 minutes) to index file since upload.
