Tracetest in Action: Running Trace-Based Tests on the OpenTelemetry Demo App with Nomad
Please note that there are no official Nomad jobspecs for either Tracetest or the OTel Demo App, so I went ahead and did the conversions myself from Kubernetes manifests to Nomad jobspecs. You can check out the jobspecs in this repo. If you’re curious as to how I went about the Kubernetes-to-Nomad conversion, you can check out my blog post on this topic. I also have a blog post dedicated to running the OTel Demo App on Nomad. If this tickles your fancy, you can check it out here.

Hands-on OpenTelemetry: Troubleshoot issues with your instrumented apps
Examples and the tutorial in this blog post use the OpenTelemetry Astronomy Shop Demo to show what you can do with OpenTelemetry and New Relic. This application is built and maintained by the OpenTelemetry open-source community, and it provides a real-world example of a distributed application that’s been instrumented with OpenTelemetry. In the Deploying the OpenTelemetry Astronomy Shop demo app section, you’ll have an opportunity to get hands-on experience spinning up your own version of this application. You’ll learn how to:

2 Years Solution Engineer Experience + 1 Support Engineering, Would my background fit moving into SRE?
I mean, you really just need experience instrumenting apps and tinkering with them to play with OTEL. https://github.com/open-telemetry/opentelemetry-demo is a good start. You can modify the collector to point to any backend of your choice.

Tracetest in Action: Running Trace-Based Tests on the OpenTelemetry Demo App with Nomad
I got to play around with these newer features last December, after a months-long hiatus, and it was really cool to see the evolution of the product. If you follow my work, you’ll know that I play in both the Kubernetes and Nomad worlds. Today, I’ll be taking you on a quick little guided tour of Tracetest, using Traces from the OpenTelemetry Demo App to give you a feel for how it works. The whole setup will be running on HashiCorp Nomad. \

Chaining API Tests to Handle Complex Distributed System Testing
By having an observability infrastructure gather information about a set of API/microservices, we can have a concise view of the operation of these services and start thinking in an observability-driven way to test your software. Tracetest can help. When given an API endpoint, Tracetest checks observability traces to see if this API is behaving as intended. For example, let’s try to test an OpenTelemetry Astronomy Store which has the exact same use cases that we want to check. To test the "Add product to the shopping cart" task, we can create a test, define a URL and payload in the trigger section that we send to the Cart API and use the specs to define our assertions, checking if the API was called with the correct Product ID and if this product was persisted correctly.

How to Convert Kubernetes Manifests into Nomad Jobspecs
In my latest Nomadification Project (TM), I got the OpenTelemetry Demo App to run on Nomad (with HashiQube, of course). To do this, I used the OpenTelemetry Demo App Helm Chart as my guide. In doing this, and other Nomadifications, I realized that I’ve never gone through the process of explaining the conversion process from Kubernetes manifests to Nomad jobspecs.
