Enhance Kubernetes with Ceph RBD: Deploy Portainer for Easy App Management

We look into Ubuntu MiniCloud which is a tool to easily spin up a cluster with Ceph, OVN and LXD. This enables you to run workloads over a large amount of servers with and easy to use web interface.

I’m trying to solve all the Advent of Code puzzles in this video series.

I took a look at the service provider interface in java. This is a needed interface to build simple services using easy building blocks to extend and improve programs or libraries. We will create one example and also look into some tools that use this interface already.

We talk about the different collection structures in Java and how to measure their performance and memory footprint Simple example of performance testing for collection types in java: package org.ea.debugger; import java.lang.management.ManagementFactory; import java.util.*; import java.util.function.IntConsumer; public class CollectionTest { public static void sleep() { try { Thread.sleep(3000); } catch (Exception e) { e.printStackTrace(); }…

We look into how to use the amazon s3 object storage API. After that, we changed it over to use our Ceph cluster and store objects in that storage engine. The s3 API is straightforward to use, and many storage engines support it out of the box.

In this video series, I try to challenge myself with the Advent of Code trials. Each solution will be published to Github, and I hope you will learn something from my coding mistakes and perhaps send some code my way on how you have done these challenges. I know by reading code, so this is…
