# This script checks if Bee nodes are reachable by inspecting the 'isReachable' field from the /status endpoint.
# It requires 'kubectl', 'curl', and 'jq' to be installed on the system.
# Usage: ./reachable.sh [NAMESPACE] [DOMAIN]
# Example: ./reachable.sh bee-testnet testnet.internal

# Use passed namespace, or default to 'bee-testnet'
NAMESPACE=${1:-bee-testnet}
DOMAIN=${2:-testnet.internal}
