MongoDB Atlas K8s Operator

As the orginal MongoDB Atlas K8s Operator is not taking Atlas users into account, I thought about writing my own operator that handles this. And as there is already a lot of stuff out there for Golang, I decided to write it in Rust.

It is in a POC state so a lot of happy path and things that are not handled yet, like:

What happens to the passwords (send encrypted via email, put into Vault?)
All the error handling regarding Atlas API
Update the Status of the k8s resource

Use it

Create the CRD

kubectl create -f crds/atlasusers.yaml

Start the operator

In the context of your choice, start the operator with the following command. You need to provide atlas MongoDB API key credentials.

cargo run --public-key <public-key> --private-key <private>

Create a new MongoDB Atlas AtlasUser K8s resource

kubectl create -f crds/examples/john_doe.yaml

What basically deployes something like that:

apiVersion: moertel.com/v1
kind: AtlasUser
metadata:
  name: johndoe
  namespace: default
spec:
  country: US
  firstName: John
  lastName: Doe
  username: johndoe@example.com
  roles:
  - orgId: "4723423423"
    roleName: "ORG_OWNER"

Check the created resource in your cluster

kubectl describe atlasusers johndoe
