+# Python Discord MongoDB
+This folder contains the configuration for Python Discord's MongoDB instance.
+
+## Volume
+A 10Gi volume is provisioned on the Linode Block Storage (Retain) storage class.
+
+## Secrets
+| Key                          | Value                      | Description                     |
+| ---------------------------- | -------------------------- | ------------------------------- |
+| `MONGO_INITDB_ROOT_USERNAME` | `pythondiscord`            | Username of root user           |
+| `MONGO_INITDB_ROOT_PASSWORD` | Root password for database | Password for the root user      |
+
+
+## Deployment
+The deployment will pull the `mongo:latest` image from DockerHub.
+
+It will mount the created volume at `/data/db`.
+
+It will expose port `27017` to connect to MongoDB.
+
+## Service
+A service called `mongodb` will be created to give the deployment a cluster local DNS record of `mongodb.databases.svc.cluster.local`.
