Jibri on Kubernetes

https://github.com/rraj-gautam/k8s-jibri
Jitsi is an online video conferencing tool, and Jibri is a part of the application overseeing recording the sessions. The downside of Jibri is that one instance of Jibri can only record one session at a time, so I implemented Kubernetes pods for multiple Jibri instances to record multiple sessions. My soundcard implementation solution helped a lot of people solve the issue they were stuck with while deploying Jibri in Kubernetes.

AWS SES: Capture Bounced Emails

https://github.com/rraj-gautam/terraform/tree/master/aws/ses-log-bounced-emails
By default, AWS does not keep track of bounced emails. This project implements AWS Lambda, SNS (Simple Notification Service), and CloudWatch to capture the bounced emails sent from AWS SES (Simple Email Service).
All the resources are Terraformed.

Rate Limiting on Istio Ingress Controller - Kubernetes

https://github.com/rraj-gautam/istio-ratelimit
This project is the Helm Charts for rate limiting on Istio. Istio does not have easy ways of implementing rate limiting to the domains. So, this project uses the Envoy filters to implement rate-limiting for any domains based on the Regex URL path. The Envoy filters look after the Istio gateways.

Trigger CronJob by CronJob - Python, MongoDB, Kubernetes

https://github.com/rraj-gautam/cronjob-trigger-cronjob
Kubernetes doesn't provide any methods to trigger the cron jobs after the successful completion of any other dependent cron job. This project provides a solution to trigger the execution of a cron job by another. It was tested using a Python Flask API in Kubernetes, which connects with MongoDB and populates the timestamps.
