Getting Started

Create a Google Cloud Platform Account

  1. Create an account on Google Cloud Platform
  2. Create a project on Google Cloud Platform, for example Trustles2020
  3. Create a service account key, rename it to credentials.json, and place it in the repository root folder.

Install Terraform

  1. Install the Terraform binary.

Setup SSH Keys

  1. Run ./scripts/gen_ssh_key.sh, or create a new ssh pair named id_rsa in the .ssh directory of this project
  2. update terraform.tfvars to have the public_key_path and private_key_path correspond to the public and private ssh keys that were just generated.

Set up terraform.tfvars

Fill in the following:

// GCP Project name, for example, trustless2020 project_name = ""

// Path of the setup script, for example, ../scripts/setup.sh script_path = ""

// Path of the public SSH key, for example ../.ssh/id_rsa.pub public_key_path = ""

// Path of the private SSH key, for example, ../.ssh/id_rsa private_key_path = ""

// Path of the GCP service account credentials, for example, ../credentials.json service_key_path = ""

// Username of the user accessing the host, for example $USER username = ""

// URL of a tar file of a backed up DB db_url = ""

Run Terraform scripts

  1. cd terraform, and terraform apply. This should take ~10 minutes for the node to start syncing

Create Session Keys

  1. After the node is syncing, SSH into the box:

    ssh -i ../.ssh/id_rsa `terraform output ip`

and use the author_rotateKeys RPC call from within the Docker container:

sudo docker exec -i kusama-validator curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "author_rotateKeys", "params":[]}' http://localhost:9933

The output will look something like:

{"jsonrpc":"2.0","result":"0xeadd8348a5cfec023c8c8dd50cd332431db87f945d4810192ad84e707b9032a7b2cbbf5a4aa996320107c6451b323793327503bd1b51f7e09a04148dbd043407b84a81df88eb15b1cb91213ef1457d790d81214aa9e52fd7de4ad1b877df3563f206b0144d58b313bed6719d2194b1ded90481c7ac30cb420505ea0b0185dc7c68bb08d7326b0568297bd3e5ea9c7113fffdbc3c3ead931d7259ec061adcc03e","id":1}

Set Session Keys and Validate

  1. Inject the above result and submit a Validate Extrinsic
