shell script to forward all the kubernetes service ports to localhost while automatically handling port numbers < 1024 (e.g.: 443 to 8443)

kubectl-forward-all-service-ports.sh

#!/usr/bin/env bash
for json in $(kubectl get svc -o json | jq -c '.items[] | select(.kind == "Service") | {name:.metadata.name, port:.spec.ports[0].port}'); do
    service=$(echo "${json}" | jq .name | tr -d '"')
    remote_port=$(echo "${json}" | jq .port | tr -d '"')
    local_port=$((remote_port))
    if [ $((local_port)) -lt 1024 ]; then
        local_port=$((local_port + 8000))
    fi
    echo kubectl port-forward "service/${service}" "${local_port}:${remote_port}"
done
