Reconfigure Octopus Deploy on a cloned VM

Exploring Octopus DeployIf you clone a VM that has an existing Octopus Deploy tentacle running, you’ll find that you’ll have a problem with a thumbprint clash.

All you need to do is generate a new thumprint using tentacle.exe. You can do this using a command window, or PowerShell…

cd "c:\Program Files\Octopus Deploy\Tentacle"
.\tentacle.exe new-certificate

This command will output a message saying “A new certificate has been generated and installed”, and will tell you the thumbprint. You can verify this change by opening the Tentacle Manager to see the new thumbprint.

Restart the tentacle to ensure it is using the new thumbprint before you pair it with your Octopus Server.
