= Creating a secret

The `Secret` object provides a mechanism to hold sensitive information such as passwords, {product-title} client configuration files, private source repository credentials, and so on.
Secrets decouple sensitive content from the pods. You can mount secrets into containers using a volume plugin or the system can use secrets to perform actions on behalf of a pod.
The following procedure adds the secret `nationalparks-mongodb-parameters` and mounts it to the `nationalparks` workload.

.Prerequisites

* You must have access to an {product-title} cluster.
* You must have installed the OpenShift CLI (`oc`).
* You have a deployed image.

.Procedure

. To create a secret, enter the following command:
+
[source,terminal]
----
$ oc create secret generic nationalparks-mongodb-parameters --from-literal=DATABASE_SERVICE_NAME=mongodb-nationalparks --from-literal=MONGODB_USER=mongodb --from-literal=MONGODB_PASSWORD=mongodb --from-literal=MONGODB_DATABASE=mongodb --from-literal=MONGODB_ADMIN_PASSWORD=mongodb
----
+
.Example output
+
[source,terminal]
----
secret/nationalparks-mongodb-parameters created
----

. To update the environment variable to attach the mongodb secret to the `nationalpartks` workload, enter the following command:
+
[source,terminal]
-----
$ oc set env --from=secret/nationalparks-mongodb-parameters deploy/nationalparks
-----
+
.Example output
+
[source,terminal]
----
deployment.apps/nationalparks updated
----

. To show the status of the `nationalparks` deployment, enter the following command:
+
[source,terminal]
----
$ oc rollout status deployment nationalparks
----
+
.Example output
+
[source,terminal]
----
deployment "nationalparks" successfully rolled out
----

. To show the status of the `mongodb-nationalparks` deployment, enter the following command:
+
[source,terminal]
----
$ oc rollout status deployment mongodb-nationalparks
----
+
.Example output
+
[source,terminal]
----
deployment "mongodb-nationalparks" successfully rolled out
