# Setup MongoDB
|
|
|
|
## Locally
|
|
|
|
You can run MongoDB locally using Docker:
|
|
|
|
```
|
|
docker run --name some-mongo -d mongo
|
|
```
|
|
|
|
You can then interact with the server using `localhost:27017`.
|
|
|
|
## Kubernetes
|
|
|
|
The easiest way to install MongoDB on Kubernetes is by using the [Helm chart](https://github.com/helm/charts/tree/master/stable/mongodb):
|
|
|
|
```
|
|
helm install mongo stable/mongodb
|
|
```
|
|
|
|
This will install MongoDB into the `default` namespace.
|
|
To interact with MongoDB, find the service with: `kubectl get svc mongo-mongodb`.
|
|
|
|
For example, if installing using the example above, the MongoDB host address would be:
|
|
|
|
`mongo-mongodb.default.svc.cluster.local:27017`
|
|
|
|
|
|
Follow the on-screen instructions to get the root password for MongoDB.
|
|
The username will be `admin` by default.
|
|
|
|
## Create a Dapr component
|
|
|
|
The next step is to create a Dapr component for MongoDB.
|
|
|
|
Create the following YAML file named `mongodb.yaml`:
|
|
|
|
```yaml
|
|
apiVersion: dapr.io/v1alpha1
|
|
kind: Component
|
|
metadata:
|
|
name: <NAME>
|
|
namespace: <NAMESPACE>
|
|
spec:
|
|
type: state.mongodb
|
|
metadata:
|
|
- name: host
|
|
value: <REPLACE-WITH-HOST> # Required. Example: "mongo-mongodb.default.svc.cluster.local:27017"
|
|
- name: username
|
|
value: <REPLACE-WITH-USERNAME> # Optional. Example: "admin"
|
|
- name: password
|
|
value: <REPLACE-WITH-PASSWORD> # Optional.
|
|
- name: databaseName
|
|
value: <REPLACE-WITH-DATABASE-NAME> # Optional. default: "daprStore"
|
|
- name: collectionName
|
|
value: <REPLACE-WITH-COLLECTION-NAME> # Optional. default: "daprCollection"
|
|
- name: writeconcern
|
|
value: <REPLACE-WITH-WRITE-CONCERN> # Optional.
|
|
- name: readconcern
|
|
value: <REPLACE-WITH-READ-CONCERN> # Optional.
|
|
- name: operationTimeout
|
|
value: <REPLACE-WITH-OPERATION-TIMEOUT> # Optional. default: "5s"
|
|
```
|
|
|
|
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here](../../concepts/secrets/README.md).
|
|
|
|
The following example uses the Kubernetes secret store to retrieve the username and password:
|
|
|
|
```yaml
|
|
apiVersion: dapr.io/v1alpha1
|
|
kind: Component
|
|
metadata:
|
|
name: <NAME>
|
|
namespace: <NAMESPACE>
|
|
spec:
|
|
type: state.mondodb
|
|
metadata:
|
|
- name: host
|
|
value: <REPLACE-WITH-HOST>
|
|
- name: username
|
|
secretKeyRef:
|
|
name: <KUBERNETES-SECRET-NAME>
|
|
key: <KUBERNETES-SECRET-KEY>
|
|
- name: password
|
|
secretKeyRef:
|
|
name: <KUBERNETES-SECRET-NAME>
|
|
key: <KUBERNETES-SECRET-KEY>
|
|
...
|
|
```
|
|
|
|
|
|
## Apply the configuration
|
|
|
|
### In Kubernetes
|
|
|
|
To apply the MondoDB state store to Kubernetes, use the `kubectl` CLI:
|
|
|
|
```
|
|
kubectl apply -f mongodb.yaml
|
|
```
|
|
|
|
### Running locally
|
|
|
|
The Dapr CLI will automatically create a directory named `components` in your current working directory with a Redis component.
|
|
To use MongoDB, replace the redis.yaml file with the mongodb.yaml above.
