# Practice - Persistent Data, Alternate User
**App Name:** switch
**Image**: nginx:1.21
**Persistent Data Directory:** /data
**CPU:** 500
**RAM:** 500
## ✅ Create Application
## ✅ Use WebTTY and enter your pod
{% content-ref url="/pages/6Lt7THKcrasjl5i7evFj" %}
[Create WebTTY](/stackos-docs/operations/create-webtty.md)
{% endcontent-ref %}
## ✅ After getting a shell into your pod
\---
## ✅ Check /data is owned by root
`root# ls -al /data`
`total 24`
`drwxr-xr-x 3 root root 4096 Jan 19 12:54 .`
`drwxr-xr-x 1 root root 4096 Jan 19 12:57 ..`
`drwx------ 2 root root 16384 Jan 19 12:54 lost+found`
## ✅ Create demo user
`groupadd demo`
`useradd demo -g demo -m`
## ✅ Give /data to demo user
`chown demo:demo /data`
## ✅ Prove we can use a user that only exists in this pod
`su - demo -c whoami`
`demo`
## ✅ Run a command as another user
`root# su demo -c "touch /data/myfile"`
## ✅ See a resulting file owned by the other user (which doesn't exist in the "hypervisor")
`root# ls -al /data`
`total 24`
`drwxr-xr-x 3 demo demo 4096 Jan 19 13:01 .`
`drwxr-xr-x 1 root root 4096 Jan 19 12:57 ..`
`drwx------ 2 root root 16384 Jan 19 12:54 lost+found`
`-rw-r--r-- 1 demo demo 0 Jan 19 13:01 myfile`
