Been following the tech communities in Ekiti from 100 Level, passionate about every bit of it, the way I swiftly leave classes to the Tech Hub even made my colleagues nickname me "Techub".

But then there was no clear path, no focus, looking around there were no cyber security communities, so what was I doing? I joined the dev communities, going to every event just for taking the swag and yes learning too.

In my past article about signing container images, got some comments which led me to digging about keyless signing of container images.

Okay you've moved your infrastructure provisioning from visiting the console page and now adopted IaC ( Infrastructure as Code) for provisioning your infrastructure using terraform.

So along the way you discovered that you will be needing some sensitive credentials like github token to use with aws amplify, datadog api and key deployments?

So you've moved your organization secret management process to Hashicorp Vault on Kubernetes ? everything is working well, but you are about promote to production, this brings alot of questions about stability, recovery and fully opeartional vault servicing your deployments.

You are definately finding ways to autoscale up and down your nodes in kubernetes cluster, and figuring out which autoscaler is the best can be hard since there are many options, which one should you go for?

Well, i would advice going for Karpenter instead of the native Cluster Autoscaler, both project are sponsored by the aws team though, but Karpenter is fast when it comes to scaling up and scaling down the nodes.

There are many tools for handling complex architecture of deploying changes of your applications from the build stage to your cluster, most times the term and process of archiving this is called GitOps only if github is being used as the single source of truth in the scenerio.

when it comes to containerized environment gracefull shutdown, process management and reducing attack surface, i believe we cant leave dumb-init out of it.

When you are preparing your vault environment for production, you would want to implement the end-to-end tls setup as stated in the hashicorp vault production-ready documentation.

Setting resource quotas such as CPU and memory limits/requests is easier said than done.

But why do you need this in the first place?

hello everyone, okay, so I did something recently with GitHub action, re-wrote and optimized a workflow of 900+ lines back to 200+
