Ziti Controller Bootstrap Domain name

[u-damien]

Hi,

I can't setup my openziti controller with the bootstrap.bash script because of the following condition:

promptCtrlAddress() {
  if [[ -z "${ZITI_CTRL_ADVERTISED_ADDRESS:-}" || "${ZITI_CTRL_ADVERTISED_ADDRESS}" =~ ^[:0-9] ]]; then
    if ! ZITI_CTRL_ADVERTISED_ADDRESS="$(prompt "Enter DNS name of the controller [required]: ")"; then
      echo "ERROR: missing required DNS name ZITI_CTRL_ADVERTISED_ADDRESS in ${BOOT_ENV_FILE}" >&2
      return 1
      # if an IP address
    elif [[ "${ZITI_CTRL_ADVERTISED_ADDRESS}" =~ ^[:0-9] ]]; then
      echo "ERROR: ZITI_CTRL_ADVERTISED_ADDRESS must be a DNS name" >&2
      return 1
    else
      setAnswer "ZITI_CTRL_ADVERTISED_ADDRESS=${ZITI_CTRL_ADVERTISED_ADDRESS}" "${BOOT_ENV_FILE}"
    fi
  fi
}

The condition for the provided dns name, only check if there are digits in dns name and not if the argument is a valid ip address.
Please use this regex instead so dns containing digits (i.e. 8a1db54a85q97d.example.com) can pass the check: ^[0-9]{1,3}(\.[0-9]{1,3}){3}$
