Creating a Farm on TFChain Devnet

Prerequisites:

  • you have to have an account (ID) on the polkadot TFChain. We create a user account in the process below. If you want to do that first, here's how you get one
  • you have to have yggdrasil networking installed on your desktop/lapop. Here's how you do that

With these two steps done - we're good to go and get a devnet 3.0 farm_id

Step 1: Copy types to clipboard

Open https://raw.githubusercontent.com/threefoldtech/tfgrid-api-client/master/types.json and copy the whole content to your clipboard.

Step 2: browse to Polkadot UI

Open the following URL based on your setup:

Paste the types in the box and hit save

Step 3: Create an account

Open the following URL based on your setup:

Click Add account, take note of the seed. Click on the Advanced creation options arrow, and select keypair crypto type: Edwards(ed25519, alternative)

Click I have saved my mnemonic seed safely and click next and fill in the required fields.

Step 4: Fund your account

On the same page, on the left top, hover over Account button and click on Transfer. First select account Alice and secondly select your newly created account from the list. Send any amount to your account (these are just tokens to play around with, they hold no real value).

Step 5: Create a Twin

Open the following URL based on your setup:

and select your account from the list. First, sign some dummy terms and conditions by selecting tfgridModule -> userAcceptTc(documentLink, documentHash) and providing some dummy link and hash. Next, select tfgridModule -> createTwin(ip) from the list.

Fill in your Yggdrasil IPV6. And click on submit transaction and sign it with your account.

Step 6: Create a Farm

Open the following URL based on your setup:

and select your account from the list. Next, select tfgridModule -> createFarm(..) from the list.

Fill in a name, select a certification type and leave country_id and city_id to 0. You can, if you want, set the country/city id values to a value from the https://explorer.devnet.grid.tf/graphql/ explorer.

To find a country or city you can query all the available countries and cities in graphql.

Optionally you can also provide public ips on your farm.

Step 7: query twin ID and Farm ID

Query twin

Open the following URL based on your setup:

and select tfgridModule -> scroll all the way down to twinIdByAccountID(accountID):u32 and select your account ID from the list. Hit the PLUS symbol and you should see your twin ID.

Query farm:

Open https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/chainstate

and select tfgridModule -> scroll to farmIdByName(bytes):u32 and search your farm ID based on your farm name. Hit the PLUS symbol and you should see your farm ID.
