Save the following ConfigMap as ``x509-mongodb-user.yaml``:
9+
10+
.. code-block:: none
11+
:linenos:
12+
13+

apiVersion: mongodb.com/v1

25+
26+
This ConfigMap ``.yaml`` file describes a ``MongoDBUser`` custom object. You
27+
can use these custom objects to create MongoDB users.
28+
29+
In this example, the ConfigMap describes the user as an X.509
30+
user that the client can use to connect to MongoDB with the
31+
corresponding X.509 certificate.

Run the following command to apply the ConfigMap and create the
39+
X.509 MongoDB user:
40+
41+
.. code-block:: sh
42+
43+
kubectl -n {namespace} apply -f x509-mongodb-user.yaml
44+
45+
You should see an output similar to the following:

Once you have created your X.509 user, try to connect to the
77+
deployment using the mongo Shell:
78+
79+
.. code-block:: sh
80+
81+
mongo --host {host} --ssl --sslCAFile /var/run/secrets/kubernetes.io/serviceaccount/ca.crt --sslPEMKeyFile x509-full.pem --authenticationMode MONGODB-X509
82+
83+
.. note::
84+
85+
On Kubernetes Pods, the |certauth| file is saved in
86+
``/var/run/secrets/kubernetes.io/serviceaccount/ca.crt``, which
87+
is the file location used for the ``--sslCAFile`` connection
88+
option.
