Step 5: Deploy MongoDB & BigchainDB
-----------------------------------
Now you can deploy MongoDB and BigchainDB to your Kubernetes cluster.
Currently, the way we do that is we create a StatefulSet with two
containers: BigchainDB and MongoDB. (In the future, we'll put them
in separate pods, and we'll ensure those pods are in different nodes.)
We expose BigchainDB's port 9984 (the HTTP API port)
and MongoDB's port 27017 using a Kubernetes Service.
Get the file ``node-mdb-ss.yaml`` from GitHub using:
.. code:: bash
$ wget https://raw.githubusercontent.com/bigchaindb/bigchaindb/master/k8s/node-mdb-ss.yaml
Take a look inside that file to see how it defines the Service
and the StatefulSet.
Note how the MongoDB container uses the ``mongoclaim`` PersistentVolumeClaim
for its ``/data`` diretory (mount path).
Create the StatefulSet and Service in your cluster using:
.. code:: bash
$ kubectl apply -f node-mdb-ss.yaml
You can check that they're working using:
.. code:: bash
$ kubectl get services
$ kubectl get statefulsets
