= 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.
|
|
|
|
