Fixing bugs/issues triggered from Linux Servers and Kubernetes Cluster of different Clients. It requires Troubleshooting skills in Linux Server and Kubernetes Cluster.
Working on features such as writing helm charts for apps, writing bash scripts to update helm charts to the latest version, writing security policies, writing golang program to sync the parent repo’s latest branch to the client repo, writing golang program to find orphan resources in the Kubernetes cluster report via notification, and much more.
This role requires the implementation of various technologies such as Puppet, Linux, Networking, Kubernetes, Containers, Golang, troubleshooting, AWS, Prometheus, Helm, Grafana, GitOps, ArgoCD, security policies, etc.
The best part was learning something new each and every day, which included technical part, time management, and soft skills.

Contributed to Kyverno/kyverno project on fixing bugs, enhancing features, writing test cases for features, etc. § github

Kyverno is a policy Engine for Kubernetes resources. It mainly has 3 types of rules: Validate, Mutate, and Generate. Worked on an § enhancement feature for the Kyverno CLI for the Mutate Rule to add the support for the ”test” command. The”test” command is used for testing the policies against a resource before deploying the policy into production.
Worked on design for 1.5 months and discussed it with the team and then spent the remaining 1.5 months in coding with golang programming language. PR link: § github, Design docs: link
Writing mutate policies and test cases for Kyverno. PR link: § github,
