Run in the cloud

You can use Terraform to spin up an Amazon EC2 instance with the node. You will need an SSH keypair to access the EC2 instance. Generate a new keypair or use an existing one.

terraform init setup/cloud
terraform apply -var ssh_public_file="~/.ssh/parsec-testnet.pub" -var ssh_private_file="~/.ssh/parsec-testnet" -var network="testnet-beta" setup/cloud

Some useful commands once it is up and running:

check the logs: ssh ubuntu@<ec2 host> journalctl -u parsec
start/stop/restart/status: ssh ubuntu@<ec2 host> sudo service parsec start/stop/restart/status
