# Secrets example
|
|
|
|
Following this example, you will create a secret and a pod that consumes that secret in a volume.
|
|
You can learn more about secrets [Here](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/secrets.md).
|
|
|
|
## Step Zero: Prerequisites
|
|
|
|
This example assumes you have a Kubernetes cluster installed and running, and that you have
|
|
installed the ```kubectl``` command line tool somewhere in your path. Please see the [getting
|
|
started](../../docs/getting-started-guides) for installation instructions for your platform.
|
|
|
|
## Step One: Create the secret
|
|
|
|
A secret contains a set of named byte arrays.
|
|
|
|
Use the [`examples/secrets/secret.yaml`](secret.yaml) file to create a secret:
|
|
|
|
```shell
|
|
$ kubectl create -f examples/secrets/secret.yaml
|
|
```
|
|
|
|
You can use `kubectl` to see information about the secret:
|
|
|
|
```shell
|
|
$ kubectl get secrets
|
|
NAME TYPE DATA
|
|
test-secret Opaque 2
|
|
|
|
$ kubectl describe secret test-secret
|
|
Name: test-secret
|
|
Labels: <none>
|
|
Annotations: <none>
|
|
|
|
Type: Opaque
|
|
|
|
Data
|
|
====
|
|
data-1: 9 bytes
|
|
data-2: 11 bytes
|
|
```
|
|
|
|
## Step Two: Create a pod that consumes a secret
|
|
|
|
Pods consume secrets in volumes. Now that you have created a secret, you can create a pod that
|
|
consumes it.
|
|
|
|
Use the [`examples/secrets/secret-pod.yaml`](secret-pod.yaml) file to create a Pod that consumes the secret.
|
|
|
|
```shell
|
|
$ kubectl create -f examples/secrets/secret-pod.yaml
|
|
```
|
|
|
|
This pod runs a binary that displays the content of one of the pieces of secret data in the secret
|
|
volume:
|
|
|
|
```shell
|
|
$ kubectl logs secret-test-pod
|
|
2015-04-29T21:17:24.712206409Z content of file "/etc/secret-volume/data-1": value-1
|
|
```
|
|
|
|
|
|
[]()
