DreamCompute instances are created with a specified SSH key which is used for gaining initial access. This guide covers some basic steps to attempt to retrieve the data, and gain access again if desired.
Things to keep in mind
IP addresses will change
To get back into an instance requires re-creating it. The new instance receives new IPv4 and IPv6 addresses.
Know your instance type
One can generally find out if an instance is ephemeral, or volume booted by looking at the dashboard in the Instances menu, and seeing if the name of an operating system is listed in the “Image Name” column. If one is listed, the instance is ephemeral. If one isn’t, it is volume booted.
Regain access to ephemeral instance
- Navigate to the DreamCompute dashboard Instances menu.
- Click on the right-side menu, the action “Create Snapshot” and give the snapshot a name. This creates an operating system image of your running instance. Please wait for this process to complete, generally no more than a couple minutes.
- Click on the “Launch Instance” button to create a new instance. For the “Instance boot source”, select “Boot from image” and then the name of the snapshot created in the previous step. On the “Access & Security” tab, select the Key Pair to be injected for the default user. If there are no valid keys available, click the “+” symbol next to the drop- down to create a new one. Click the “Launch” button on the bottom right.
- Once the new instance has booted, attempt to login to it with the default username and the new IP address.
- If all looks correct and access has been restored, the original instance can now be deleted.
