Hello,

I’m trying to deploy a server using a template that contains a start\_script = “touch /root/TEST.txt” in the context section but it doesn’t work, any suggestions?

Thank you.

</div>

my start script looks like this and works:

#!/bin/bash

if [-d “/etc/this\_folder”]; then  
:  
else  
mkdir /etc/this\_folder  
fi

i put a bash script in the start script to rule everytime the VM power ups.

Hello @jeyc,

The problem is that your `START_SCRIPT_BASE64` is not in base64 form, you should have something like: `IyEvYmluL2Jhc2gKdG91Y2ggL3Jvb3QvVEVTVC50eHQK`.

Best,  
Álex.

Go to Templates - VMs - select your VM template  
Then “update” - “context” - and there you enter the bash script  
after that you click on the “update” button and then you’ll see in the template the BASE64 hash mentioned by Alex above me.

Hello,

I have managed to make it work by installing the one\_context package in the virtual machine and restarting it, but curiously I have lost the IP address. I’m still investigating.

Thank you.
