PROXY Protocol Waypoint

This sample demonstrates a non-Istio waypoint defined using static Envoy config.

1. Create a kind cluster

Debugging Pilot with Delve

First build pilot with GCFLAGS="all=-n -l":

GCFLAGS="all=-N -l" HUB=docker.io/slandow TAG=slandow BUILD_IN_CONTAINER=1 make docker.pilot

Then we can wrap that image in one that includes delve:

Allows encoding a small image with a limited number of colors into an integer.

The bit-width of a pixel in the image is ceil(log2(n_colors)).

The bit-width of a socket image int is pixel-bit-width * size^2)

This python implementation doesn't concern itself with what the bit-width of the entire integer is. Real implementations care. This is determined by the image size. I'm assuming all images are square. When I say the size is "4" I really mean "4x4"). An image with size 4 with 4 possible colors would have 16 pixels and each pixel requires 2 bytes. This means we need a 32 bit int to hold our image,
