Deploying Keycloak to AWS

The objective of this guide is to deploy Keycloak to AWS in a minimally complex way for testing and discovery purposes. This means using the standalone build of Keycloak backed with Hibernate H2. The result is not a production ready system. It won't scale, it won't survive significant load, it can't be clustered.

Mostly this Gist is a distillation of the Keycloak Server Installation guide for a specific use case: to spin up a quick and dirty Keycloak instance for testing and experimenting.

Steps

Spin up and configure a Ubuntu AMI
Install and configure Keycloak with an SSL cert

	Shortest path on a grid
	1. In robotics, a robot often to find a plan (a path or a set of actions) to reach its goal. Write code to determine the shortest path on a grid. Where the grid is square with the length of side N = 10. In one step the robot is only allowed to move to a cell adjacent to its current cell, i.e., robot can move up, down, left, right (not diagonally). The robot can start at a point (0,0) and its goal location (7,9) assuming the row and column values are indexed starting at 0. Your output is to print the sequence of cells that the robot will visit. You can print the row, col value for each cell that the robot visits on its way to the goal.
	Bonus Question: Now lets say someone placed an obstacle at (6,7) and (2,2). An obstacle means that the robot can no longer go through that cell. How will your solution change? Implement your solution and print the path.
	Objective: Write a function "findShortestPath(const int N, const int startx, const i
