title: Configure a Pod to Use a Projected Volume for Storage
|
|
---
|
|
|
|
{% capture overview %}
|
|
This page shows how to use a [`projected`](/docs/concepts/storage/volumes/#projected) volume to mount several existing volume sources into the same directory. Currently, `secret`, `configMap`, and `downwardAPI` volumes can be projected.

## Configure a projected volume for a pod
|
|
|
|
In this exercise, you create username and password Secrets from local files. You then create a Pod that runs one Container, using a [`projected`](/docs/concepts/storage/volumes/#projected) Volume to mount the Secrets into the same shared directory.
|
|
|
|
Here is the configuration file for the Pod:
|
|
|
|
{% include code.html language="yaml" file="projected-volume.yaml" ghlink="/docs/tasks/configure-pod-container/projected-volume.yaml" %}
|
|
|
|
1. Create the Secrets:
|
|
|
|
# Create files containing the username and password:
|
|
echo -n "admin" > ./username.txt
|
|
echo -n "1f2d1e2e67df" > ./password.txt
|
|
|
|
# Package these files into secrets:
|
|
kubectl create secret generic user --from-file=./username.txt
|
|
kubectl create secret generic pass --from-file=./password.txt
|
|
|
|
1. Create the Pod:
|
|
|
|
kubectl create -f projected-volume.yaml
|
|
|
|
1. Verify that the Pod's Container is running, and then watch for changes to
|
|
the Pod:
|
|
|
|
kubectl get --watch pod test-projected-volume
|
|
|
|
The output looks like this:
|
|
|
|
NAME READY STATUS RESTARTS AGE
|
|
test-projected-volume 1/1 Running 0 14s
|
|
|
|
1. In another terminal, get a shell to the running Container:
|
|
|
|
kubectl exec -it test-projected-volume -- /bin/sh
|
|
|
|
1. In your shell, verify that the `projected-volume` directory contains your projected sources:
|
|
|
|
/ # ls /projected-volume/
|
|
{% endcapture %}
