How to Install MongoDB on Kubernetes? (External Access | Prometheus | TLS | Kubernetes Operator)
Source: YouTube · Anton Putra · published Jan 24, 2022 · 17:59
The video demonstrates how to deploy MongoDB to Kubernetes using an open-source operator and configure it with scaling, TLS security, external access, and monitoring 0:03. The presenter shows a complete workflow from basic deployment to production-ready configuration with Prometheus monitoring 0:48.
Key Takeaways:
• The tutorial begins with deploying a single MongoDB instance using the Kubernetes operator and connecting locally via port forwarding 0:08 3:53
• MongoDB is scaled to three replicas (one primary and two secondaries) by simply changing a configuration value and applying the changes 0:18 5:34
• The cluster is secured using TLS through cert-manager to bootstrap PKI infrastructure in Kubernetes and create certificates 0:28 9:03
• External access is configured with load balancers and proper DNS records (CNAME and SRV) to securely connect from outside the cluster 0:33 11:33
• Prometheus, Grafana, and MongoDB exporter are deployed for comprehensive monitoring of the cluster and database metrics 13:57
This tutorial provides a complete production-ready MongoDB deployment on Kubernetes with all the essential components for security, scalability, and observability 17:53.

Today we will deploy MongoDB database
to Kubernetes using the open-source Kubernetes operator. First of all, we are
going to deploy a single MongoDB instance. We will use port forward and connect to it
with MongoDB Shell from the local computer. Then we will scale it up to 3 replicas. One of
them will be primary and two secondary replicas. After that, we will bootstrap out Private Key
Infrastructure (PKI) in Kubernetes using the cert-manager and secure our MongoDB cluster with
TLS. For the final example, we will configure external access and secure connections with TLS
as well. And of course, we will monitor every single component in Kubernetes with Prometheus,
including MongoDB. To monitor the database, we will deploy Prometheus exporter and cadvior
to collect basic metrics such …
