What are your must-have scripts/playbooks for on-prem?

I’m currently working on a Terraform module to automate VMware Windows/Linux VM deployments. Possibly also reference an Ansible Playbook to join our domain and other time-consuming tasks.

What do you guys use to improve your lives tremendously when not using cloud?

Chef Workstation on Ubuntu 22.10

Can you install Chef Workstation on Ubuntu 22.10?

I can't seem to find anything on the net for it. Only thing I find for is Ubuntu 18.04 and possibly 20.04 but nothing for newer versions.

Propagating image changes to a k8s cluster

I have a CI loop in a repository that automatically builds and publishes a container on merge to the main branch. Usually, images are tagged per git hash, however, when they are proven stable, they are additionally tagged with latest.

The deployment for Kubernetes is pointing to the latest tag. How would I automate updating the Kubernetes deployment when a new image is tagged with latest? Or am I simply going about this the wrong way?

Expensive Metrics: Why Your Monitoring Data and Bill Get Out Of Hand

Why does our metric data volume and our bill get out of control? How is it related to cardinality? And how can DevOps and SRE proactively manage it?

Ever Reach the Point Where Despite Using Containers You Still Get “Works on my Machine”

I’m on hour 3 of debugging a CI pipeline where it runs 100% of the time when calling my Molecule test directly. If I call it through pytest which we use to parallelize those tests, fails every time. I didn’t write the pipeline so mostly just reading code and the spaghetti of how it’s all wired up.

Just thought I’d seek commiseration and funny stories of still hitting the “works on my machine” wall despite using containers.

How can I check if my ISP is filtering some hosts?

I seriously suspect that my ISP is limiting traffic to Reddit, I'd like to prove if this is true.
I'm a Software BE engineer and have some knowledge of networking and infrastructure and can handle a terminal. Someone could somehow guide me? I don't know how feasible could be.

Thanks!

I wrote this guide on how to move from TDD to ODD

https://tracetest.io/blog/the-difference-between-tdd-and-odd

E2E testing on the back end is tricky because mocking data on the back end is tricky.

A way to avoid this is trace-based testing where you can run tests and assert against traces. You're really running tests against actual data—no more mocking data and wasting your time.

Network security on Azure and GCP

So, in our web app, which is hosted in multiple data centers (DCs), we can post content in a form field. When posting content like "<script>test</script>" in on-prem DCs, it works, no problem. However, in some Azure and GCP hosted DCs, the post fails with ERR CONNECTION RESET. We checked the firewalls where the post fails and no packets were dropped. Could there be another Azure or GCP network configuration that blocks content in JavaScript script tags? Where should I begin to troubleshoot this, since our web app's codebase is the same in all the DCs.

Creating a VPN to control access to a dev environment?

Currently, I have 1 server running Kubernetes (k3s) where I deployed a preview version of a website for the dev team. The site is currently exposed to the internet.

I would like to somehow create something like VPN to restrict access to the site from the public internet. The problem is I only have 1 server and that server is in a network to which I don't have direct access to. It just has 1 public IP assigned and I managed it thorough SSH.

What would be an ideal solution for this? I have only seen an environment where there is a VPN gateway and a network of multiple servers in a private network, but I have just one.

Saving load test results for comparison

We've introduced an automated load test pipeline for regularly validating the performance of our website. It's written in .NET and uses Azure Pipeline to run. I'm now looking for a way to properly visualize the results and compare them with previous results.

Does anybody have a suggestion on how to do this properly? Or does anybody know some generic software where you can 'push' data-entries (like a JSON object with date, number of requests, average response time, etc.) and create some diagrams on those data-entries?

RedHat Certifed SysAdmin Resource

I am transitioning from backend engineering to devops. I have basic linux skills that comes across my day to day jobs. These are mostly related to text / listing / copy / move / kill processes. I can also do average or below average bash scripting while making CI / CD pipelines mostly.

Recently I have speedup my learning in devops space and want to get some certification specially for linux administration.

I am looking for recommendation for best learning material that can help me prepare for exam. I am a video lessons person hence looking for video course.

Thanks

Terraform - How do you handle secrets?

Hey I am new to Terraform and I have wondered about this.
When you need to create a resource that has a sensitive secret what do you do?
For example creating a user with a password.

I would like to keep that stuff out of the terraform state file.

Thank you!

Self-Hosted Secrets Management Service Recommendations?

Hi all. Our company is currently shopping around for a good service to allow for secrets management (primarily with Node apps) that can be integrated into CI/CD pipelines. We currently use Azure infrastructure, and initially were going to use Azure Key Vault, but found that the UX was less than ideal. This led to finding Doppler, and while it looks fantastic, the lack of self-hosting ability is a turnoff. This then led to finding Infisical, but does not look to be feature complete and is rather new.

What do you use for Secrets Management? What recommendations do you have? Any self-hosted options that also have Doppler's branching/schema features?

Push part of build output back into repo?

I've got a situation where our final build step produces 2 things:

- Release artifacts (zipped executables for different platforms)
- Files that need to be checked into the Git repo for future use (in the repo itself, not as a Release artifact)

The later is giving me a bit of a headache.

Is there a "best practice" for pushing parts of the build output back into the original Git repo?

Our setup is Gitea and Drone CI if that helps.
