# When you need to process a hash with keys in sorted order
# you may have found the `sort()` function - but it only
# operates on an Array.
#
# Most of the time what is wanted is simply achieved
# by taking the keys of a hash and sorting those and
# then iterating over the keys.
#
# When, however the wanted result is a new Hash
# with all keys sorted recursively then this becomes

HTTP tunnel

On prem k8s cluster set up with bastion vm

1. Create a bastion vm in your data center or in cloud with connectivity set up (usually vpn) to the on prem data center.
2. Install tinyproxy on the bastion vm and pick a random port as it would be too easy for spam bot with default 8888, set up as systemd service according to https://nxnjz.net/2019/10/how-to-setup-a-simple-proxy-server-with-tinyproxy-debian-10-buster/. Make sure it works by validating with curl --proxy http://127.0.0.1:<tinyproxy-port> https://httpbin.org/ip. And I don't use any user authentication for proxy, so I locked down the firewall rules with my laptop IP/32.
3. Download the kubeconfig file for the k8s cluster to your laptop
4. From your laptop, run

HTTPS_PROXY=<bastion-external-ip>:<tinyproxy-port> KUBECONFIG=my-kubeconfig kubectl get nodes

## HTTP Router benchmarks -- Nov 29, 2020 with Go 1.15.5 on Linux AMD 3950x
##
## This benchmark suite is based on https://github.com/julienschmidt/go-http-routing-benchmark
## using the most up-to-date version of each pkg as of today. Each router has their own
## pros and cons, so consider the designs of each router to suit your application.
##
## *NOTE*: the memory reports below by the go benchmark tool look quite wrong, as there must
## be a bug somewhere in the go bench tool with the Go version I'm running. I will re-run
## with future versions and report back. However, in general you'll want to look at the "ns/op"
