Start an IPFS daemon if not running

[bmann]

The recommended way to detect if IPFS is running is to run:

ipfs swarm addrs

From ipfs/kubo#5983 and aragon/aragon-cli#845

I'm documenting this for now when / if we end up running IPFS ourselves in the CLI.

Are you able to share a code example of how to wait until the IPFS daemon is running? I have tried to write a script based on waiting until ipfs swarm addrs but I have been running into problems with it.

Hey @jamiehewitt15 here's a link to the code in Haskell, but this is going to very programming language specific https://github.com/fission-suite/fission/blob/cc8a01208d05802eb05fd9bcbe4b15243c8e4ae6/fission-cli/library/Fission/CLI/Types.hs#L375

Basically, how the PL handles spawning applications and communicates with them at the system level.

Feel free to come by our Discord chat https://fission.codes/discord if you want to talk further, I'm going to close this issue because we do, indeed, install and spawn the go-ipfs daemon ourselves now.
