Healthcheck

A script called healthcheck.sh is copied into /usr/local/bin. This can be used to check the health of the service. Here is an example of how it can be used with Hashicorp Nomad + Consul;

# Registers service with consul for service discovery
service {
  name = "chia-node"
  port = "rpc"

  tags = [
    "private"
  ]

  check {
    name     = "alive"
    type     = "tcp"
    interval = "10s"
    timeout  = "2s"
  }

  # Need to use a script check because the HTTP request to chia node must contain a body which cannot be done specified in the check stanza
  check {
    name     = "get_blockchain_state"
    type     = "script"
    command  = "/bin/bash"
    args     = ["/usr/local/bin/healthcheck.sh"]
    interval = "10s"
    timeout  = "5s"

    check_restart {
      # Restart after 2 consecutive failures
      limit = 2
      # After restarting do not check health for 90s
      grace = "90s"
      ignore_warnings = false
    }
  }
}

When it fails the Chia node is restarted by Nomad;
