This is a Kubernetes Operator which deploys MongoDB Community into Kubernetes clusters.

If you are a MongoDB Enterprise customer, or need Enterprise features such as Backup, you can use the MongoDB Enterprise Operator for Kubernetes.

Here is a talk from MongoDB Live 2020 about the Community Operator:

• Run it in Kubernetes! Community and Enterprise MongoDB in Containers

Note

Hi, I'm Dan Mckean 👋 I'm the Product Manager for MongoDB's support of Kubernetes.

The Community Operator is something I inherited when I started, but it doesn't get as much attention from us as we'd like, and we're trying to understand how it's used in order to establish it's future. It will help us establish exactly what level of support we can offer, and what sort of timeframe we aim to provide support in 🙂

Here's a super short survey (it's much easier for us to review all the feedback that way!): https://docs.google.com/forms/d/e/1FAIpQLSfwrwyxBSlUyJ6AmC-eYlgW_3JEdfA48SB2i5--_WpiynMW2w/viewform?usp=sf_link

The MongoDB Community Kubernetes Operator supports the following features:

• Create replica sets
• Upgrade and downgrade MongoDB server version
• Scale replica sets up and down
• Read from and write to the replica set while scaling, upgrading, and downgrading. These operations are done in an "always up" manner.
• Report MongoDB server state via the MongoDBCommunity resource status field
• Use any of the available Docker MongoDB images
• Connect to the replica set from inside the Kubernetes cluster (no external connectivity)
• Secure client-to-server and server-to-server connections with TLS
• Create users with SCRAM authentication
• Create custom roles
• Enable a metrics target that can be used with Prometheus
