How to make your snapshot usable by other members of your project¶

Step 1: Cleaning up the Image¶

Before you make the snapshot, you may want to delete some local settings such as ssh authorized key, bash_history, and some customization scripts from your image. Here we describe the steps that should have been carried out for this purpose.

Remove authorized key from your ssh agent:
```
> ~/.ssh/authorized_keys
```
Note: Once you remove your public key from the authorized_keys file , you won't be able to login back to the instance.
Remove authorized key from 'root' ssh agent:
```
sudo su -
> ~/.ssh/authorized_keys
exit
```

Delete the following folders recursively

sudo rm -r /var/lib/cloud/data/*
sudo rm -r /var/lib/cloud/instances/*
sudo rm -r /var/lib/cloud/instance/*
sudo rm -r /var/lib/cloud/handlers/*
sudo rm /etc/cloud/uzh-customization-script
sudo rm /var/log/*.log

Step 2: Creating the Snapshot¶

Log in to https://cloud.s3it.uzh.ch.
On the Project tab, open the Compute tab and click Instances category.
Select the instance of which you'd like to take a snapshot.
1. Click on Shutoff instance
2. Click on Create Snapshot
3. Snapshot Name: Give a descriptive name to your snapshot
4. Click on Create Snapshot
Your snapshot will be displayed under Images.
You should then follow the directions in this how-to article to turn your snapshot into a usable image.
