Singularity Workshop Guide

Welcome to the Singularity Workshop!

Getting Started

This instruction will guide you through all steps necessary to use Singularity to

  1. Prepare an open dataset from S3
  2. Send deal to a local emulated storage provider f02815405
  3. Make retrievals from the emulated storage provider using HTTP and Bitswap

Initial Setup

Note This process will require you to download the sim-sp software, a simulated storage provider.

Download Singularity and sim-sp:

  • Get the latest Singularity release here.
  • Download the latest sim-sp release here.
  • Note Avoid package formats like '.deb' or '.rpm'.

  1. Extract and Organize:

    • Locate the downloaded files, usually in the Downloads folder.
    • Double-click each file to extract. Move the extracted contents (look for files named singularity and sim-sp) into a new folder on your Desktop, named SingularityWorkshop.

  2. Prepare Your Environment:

    • Open the Terminal application (found in Applications > Utilities).
    • Change the directory to your workshop folder:
cd ~/Desktop/SingularityWorkshop
  • Verify the setup by running:
SingularityWorkshop % ./singularity version  

singularity v0.5.11-5c597b4
     
SingularityWorkshop % ./sim-sp     

NAME:
sim-sp - Utility for simulating a storage provider

USAGE:
sim-sp [global options] command [command options] [arguments...]

COMMANDS:
run            Run the simulated storage provider f02815405
generate-peer  Generate a new peer
help, h        Shows a list of commands or help for one command

GLOBAL OPTIONS:
--help, -h  show help

If you encounter an error message stating that the software cannot be opened because it's from an unidentified developer, you can adjust your Mac's security settings to allow these applications through Gatekeeper with the following commands.

xattr -d com.apple.quarantine singularity
xattr -d com.apple.quarantine sim-sp

For Windows user, you will need to use below command for the whole workshop

singularity.exe version
sim-sp.exe -h
  1. Download IPFS CLI:
    • Download the IPFS CLI for Mac from here.
    • Repeat the extraction process and ensure the ipfs executable is in the SingularityWorkshop folder.

Singularity Setup

  1. Initialize Singularity:
    • In the Terminal, within your SingularityWorkshop folder, initialize Singularity's database:
    ./singularity admin init
 
2024-01-23T00:15:08.417-0500	INFO	model	model/migrate.go:51	Auto migrating tables

Resetting the Database:

  • In case you need to reset the database, perform the following:
./singularity admin reset --really-do-it

2024-01-23T00:17:47.840-0500	INFO	model	model/migrate.go:100	Dropping all tables
2024-01-23T00:17:47.847-0500	INFO	model	model/migrate.go:51	Auto migrating tables

Preparing Data

  1. Connect to AWS S3:
    • Connect to AWS S3 bucket as a storage connection. Let's name the connection as civic
./singularity storage create s3 aws --region us-west-2 --name civic --path civic-aws-opendata
     
ID  Name   Type  Path                
1   civic  s3    civic-aws-opendata
  • Check the connection:
./singularity storage list
     
ID  Name   Type  Path                
1   civic  s3    civic-aws-opendata
  1. Data Preparation:
    • Prep the data for scanning:
./singularity prep create --name civic --source civic

ID  Name   DeleteAfterExport  MaxSize      PieceSize    NoInline  NoDag  
1   civic  false              33822867456  34359738368  false     false  
Source Storages:
   ID  Name   Type  Path                
   1   civic  s3    civic-aws-opendata
  • Start the scanning process:
./singularity prep start-scan civic civic

ID  Type  State  ErrorMessage  WorkerID  
1   scan  ready                <nil>

Note Now the data source is marked as ready to be scanned, but we have not yet started running any worker to scan and prepare the dataset. Usually the dataset worker should be always running, but in this workshop, we are going to run it on-demand. The command will take one minute to complete depending on the Internet speed, it will look like it hangs at created pack job 2 with 43 (numbers may vary) file range but it will finish soon. The command will exit upon completion of data preparation.

  1. Run Dataset Worker:
    • Open a new Terminal window and navigate to SingularityWorkshop.
    • Run the dataset worker:
./singularity run dataset-worker --exit-on-error --exit-on-complete

...

    • Once the dataset-worker has completed, start DAG generation:
./singularity prep start-daggen civic civic

ID  Type    State  ErrorMessage  WorkerID

  • Run the dataset worker again to complete the process:
./singularity run dataset-worker --exit-on-error --exit-on-complete

Great, we have completed the data preparation and can now list all prepared pieces using below command. It will show piece_size and piece_cid of each pieces which are very important parameters in deal proposals to storage providers.

  • List all prepared pieces

Distributing and Retrieving Data

  1. Running the Content Provider:
    • In a 3rd new Terminal window, run the content provider:
./singularity run content-provider

  1. Making Deals:

Note Go back to your first terminal window before executing the following commands.

  • Import a test wallet. We will use a known private key for the test:
./singularity wallet import

   Enter the private key:          7b2254797065223a22736563703235366b31222c22507269766174654b6579223a226b35507976337148327349586343595a58594f5775453149326e32554539436861556b6c4e36695a5763453d227d

  • In your 2nd Terminal window, run the emulated storage provider:
./sim-sp run

  1. Send Out Deals:

Finally, it's time to send out the deals, to simplify this process, we are going to send deals for all available pieces from this open dataset to the storage provider. Do not change the miner id f02815405, do NOT replace {PIECE_CID}.

  • In your command terminal window, Schedule deals:
./singularity deal schedule create --verified=false --preparation civic --provider f02815405 --url-template "http://127.0.0.1:7777/piece/{PIECE_CID}"

ID  Provider   TotalDealSize  Verified  StartDelay  Duration    State   ScheduleCron  ScheduleCronPerpetual  ScheduleDealNumber  ScheduleDealSize  MaxPendingDealNumber  MaxPendingDealSize  Notes  Force  PreparationID

  • In another new Terminal window, push out the deals:
./singularity run deal-pusher

2024-01-23T09:41:50.255-0500	INFO	dealpusher	service/service.go:61	starting service	{"name": "DealPusher"}

You will now have things happening in 3 different terminal windows.

Singularity Deal Pusher is sending deal proposals to the emulated storage provider. Sim-sp is receiving boost online deals and is trying to download and parse the CAR files from Singularity Content Provider. Singularity Content Provider is reading S3 objects and converting into CAR stream for download.

Wait until you see two of Deal xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx completed successfully, then you are ready for the upcoming retrieval session. You may also kill the deal-pusher and content-provider service and leave sim-sp running for retrievals.

Retrievals

The emulated Storage Provider will enable IPFS Gateway so you can actually browse the dataset using the RootCID by go to http://127.0.0.1:7778/ipfs/bafybeihien4mh6kuiggh3hpejefwihkedhcjwihvz35j7iqj3gfvqmukgi, this RootCID comes from the preparation result ./singularity prep explore civic civic

You may also browse the files using IPFS Gateway and download files via any HTTP clients.

  1. Initialize IPFS:
    • In a new Terminal window, initialize and run IPFS:
ipfs init
ipfs daemon
  1. Connect to Storage Provider:
    • Connect to the emulated storage provider:
ipfs swarm connect /ip4/127.0.0.1/tcp/24001/p2p/12D3KooWDeNSud283YaRmhqbZDynLNmtATBxjUPAUJxtPyEXXp9u

connect 12D3KooWDeNSud283YaRmhqbZDynLNmtATBxjUPAUJxtPyEXXp9u success
  1. Retrieve Dataset:
    • Retrieve the dataset using the RootCID:
ipfs get -o out bafybeihien4mh6kuiggh3hpejefwihkedhcjwihvz35j7iqj3gfvqmukgi

You've successfully navigated the Singularity Workshop! If you encounter any issues or have questions, refer to the Filecoin documentation for additional information.

Note The new version of Boost (v2) no longer supports the trusted IPFS gateway by default. https://boost.filecoin.io/retrieving-data-from-filecoin/http-retrieval#trusted-plain-file-directory-retrievals
