Advent of Code – Day 2

We will look into the Ceph dashboard and the different metrics you can find there. Then we will configure Prometheus Alertmanager to get timely alerts from the metrics in your Ceph Cluster.

We will look into using Svelte with webpack and code some specific code that will be compiled to javascript native code for faster execution.

In this video, we look into installing Placement and Nova services. The Placement service is used to gather statistics about your cluster and figure out where to put instances. Nova is the controller and compute nodes that will do the actual work.

We are in our new linux environment and create gettext and OpenSSL, talking about internationallization and website security.

We look into how to use the Slim 4 framework. First, we will talk about the difference between the Slim 3 generated code from OpenAPI and then we will look at the new requirements for Slim 4 and how to run it in a production environment.

We look into high availability using Heartbeat and DRBD. Heartbeat is a software to monitor and failover when a machine is unresponsive and DRBD can help you replicate data between machines making your setup highly available. This solution can help you doing maintenance work without downtime.
