Guidance for running a MongoDB database cluster on the Kubernetes orchestration framework, leveraging Docker containers. StatetfulSets is a key dependency, to provide stable dedicated network storage volumes and hostnames, enabling data to outlive the lifetime of ephemeral containers. Note: The MongoDB Operator for Kubernetes incorporates these and other best practices in an easy to deploy way.

Introduction To Running MongoDB on Kubernetes

  1. Deploying a MongoDB Replica Set as a Kubernetes StatefulSet
  2. Configuring Some Key Production Settings for MongoDB on Kubernetes
  3. Using the Enterprise Version of MongoDB on Kubernetes
  4. Deploying a MongoDB Sharded Cluster using Kubernetes StatefulSets
  5. MongoDB and Kubernetes Home Page
  6. MongoDB Operator for Kubernetes (by Robert Walters & Andrey Belik)

WARNING: Some online resources advocate deploying a sidecar, called mongo-k8s-sidecar, to help “auto-configure” a MongoDB cluster. Do NOT employ that approach in Production environments, because this will result in non-deterministic behaviour, adversely affecting database resiliency.

Example Quickstart GitHub Projects

  1. Deploying a MongoDB Replica Set to the Google Kubernetes Engine (GKE)
  2. Deploying a MongoDB Sharded Cluster to the Google Kubernetes Engine (GKE)
  3. Deploying a MongoDB Replica Set to the Azure Container Service (ACS)
  4. Deploying a MongoDB Replica Set to a local Minikube environment
  5. Deploying a MongoDB Replica Set to an OpenShift environment
  6. Deploying a MongoDB Replica Set to GKE Using MongoDB Cloud/Ops Manager

Getting Help on Stack Overflow

  1. “kubernetes” tagged questions
  2. “google-kubernetes-engine” tagged questions
  3. “azure-container-service” tagged questions
  4. “minikube” tagged questions
  5. “openshift” tagged questions
  6. “mongodb” tagged questions

RECOMMENDED: When creating a new Stack Overflow question, define at least 2 tags: “mongodb” + a tag relating to the type of host Kubernetes environment.
