IPFS
IPFS (InterPlanetary File System) is a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system. IPFS aims to make the web more efficient, resilient, and open by using content-addressing to uniquely identify each file in a global namespace. IPFS also enables persistent availability of data with or without internet backbone connectivity, and complements HTTP.
Installation
Install and enable kubo, which is the recommended IPFS implementation
services.kubo = {
enable = true;
settings.Addresses.API = ["/ip4/127.0.0.1/tcp/5001"];
};
Currently settings.Addresses.API
need to be non-empty, otherwise Kubo will not start. See this issue for details.
Usage
Publish a file and read it afterwards
# echo "hello world" > hello
# ipfs add hello
This should output a hash string that looks something like:
QmT78zSuBmuS4z925WZfrqQ1qHaJ56DQaTfyMUF7F8ff5o
# ipfs cat <that hash>
Download a file given a hash
# ipfs get <hash>
Publish and print directory content. For the ls command, use the hash of the root directory.
# ipfs add -r folder
# ipfs ls <hash>
# ipfs ls <hash>/subdirectory
