I just started a final test: we should have max 6 devices created (the kubeadm tests create 3 machines each, the others just one each). Result: We got a maximum of 5 instances created and 3 instances have been recycled. |
we keep a trace of opened SSH client in order to close them properly later. Signed-off-by: Mathieu Tortuyaux <[email protected]>
we can now open, keep a trace and delete properly a SSH client. When the instance is created, its SSH client will be stored and closed when the device is marked as available. Signed-off-by: Mathieu Tortuyaux <[email protected]>
This devicesPool will be used to keep the devices _after_ being used in order to create a pool of available device to be picked-up later instead of creating a new device. Signed-off-by: Mathieu Tortuyaux <[email protected]>
before creating a device we check if there are some available devices into a created pool of device. if one device is available this one will be updated in place in order to boot with a new PXE configuration to load fresh configuration without destroying the server. Signed-off-by: Mathieu Tortuyaux <[email protected]>
since the mach.Destroy only adds devices to the pool, we don't need to rely on it to actually remove a device. Signed-off-by: Mathieu Tortuyaux <[email protected]>
we now define CreateOrUpdateDevice. Signed-off-by: Mathieu Tortuyaux <[email protected]>
