Debug JavaScript in Google Chrome's Dev Tools in 7 easy steps

This article will focus on debugging JavaScript code within Google Chrome’s Developer Tools. Chrome’s Developer Tools are extremely powerful and will almost certainly speed up your troubleshooting process. We’ll be using Raygun Crash Reporting to find the stack trace and the line of code the error occurred on. You can sign up for a free 14-day trial here. So, let’s dive in!

Dynamic SSL Certificate Storage in HAProxy

Use the HAProxy Runtime API to update SSL certificates in HAProxy without a reload. When you route traffic through an HAProxy load balancer, you gain the ability to terminate SSL at the load balancer. HAProxy encrypts communication between the client and itself and then sends the decrypted messages to your backend servers, which means less CPU work on the servers because there’s no encryption work left to do.

Live Kubernetes Debugging with the Elastic Stack - Philipp Krenn (Elastic)

Your Kubernetes app is down. Your users start ranting on Twitter. Your boss is standing right behind you. What do you do? This talk walks you through a live debugging session without panicking: We are using the Elastic Stack in this demo with a special focus on its Kubernetes integration with metadata enrichment and autodiscovery in combination with APM / tracing, metrics, logs, and health checks.

DevOps Patterns and Antipatterns for Continuous Software Updates - Baruch Sadogursky (JFrog)

So, you want to update the software for your user, be it the nodes in your K8s cluster, a browser on user’s desktop, an app in user’s smartphone or even a user’s car. What can possibly go wrong? In this talk, we’ll analyze real-world software update fails and how multiple DevOps patterns, that fit a variety of scenarios, could have saved the developers. Manually making sure that everything works before sending an update and expecting the user to do acceptance tests before they update is most definitely not on the list of such patterns.

Debugging, distributed tracing, and profiling for web applications

Google Cloud offers many tools that can help you manage your application services. In this video, we teach you how to set up and utilize Cloud Trace, Cloud Profiler, and Cloud Debugger to collect latency data across different services, memory-allocation information, and inspect application code locations without compromising the performance of your web application.

What is a Kubernetes Operator and Why it Matters for SRE

Kubernetes is an open-source project that “containerizes” workloads and services and manages deployment and configurations. Released by Google in 2015, Kubernetes is now maintained by the Cloud Native Computing Foundation. Since its release, it has become a worldwide phenomenon. The majority of cloud native companies use it, SaaS vendors offer commercial prebuilt versions, and there’s even an annual convention!

[Webinar] Kubernetes Applications Log Monitoring For DevOps With JFrog And Platform9

By design Kubernetes applications generate a high volume of log data across what could be hundreds of nodes. Centralized logging becomes critical for production applications, as it is otherwise near-impossible to quickly find the correct log file, and logs can be lost when pods crash.
