[Feature]: Respect nodes.target during fleet in-place update #3812
Description
Problem
nodes.target is ignored when performing fleet in-place update. Respecting nodes.target will allow to:
- Pre-provision more instances into an existing fleet.
- Terminate excessive idle fleet instances.
Solution
Respect nodes.target during fleet in-place update.
- If
nodes.targetis greater than the current number of instances, provision new ones to reachnodes.target. - If
nodes.targetis less than the current number of instances, terminate some of the idle ones to get as close as possible tonodes.target. Do not terminate busy instances. - If
nodes.targetis equal to the current number of instances or unspecified, do nothing.
Workaround
- For pre-provisioning — increase
nodes.min, apply, revertnodes.min, apply. - For terminating —
dstack fleet delete -i ...

@r4victor, does this match what you have in mind for fleet in-place update?

Yes, I was thinking about it when doing #3775 but decided to do it separately since " terminate some of the idle ones" will require locking instances in fleet apply, which is not currently necessary for other in-place updates.
