Scale Group Actions

Use this page to understand the lifecycle actions for a scale group: resizing the active node count, stopping and starting the group, and deleting it. Actions are available from the three-dot Actions menu on the Auto Scaling list and from the scale group details page.

The portal enables or disables each action based on the scale group's current status and your project permissions (update or delete). To edit a group's node counts or policies, see Scale Group Details and Editing.

Action Availability

Action	Available when status is	Disabled during	Permission
Resize Service	Running, Failed, or Failed Deleting	Scaling	Update
Start	Stopped	Starting, Stopping	Update
Stop	Running	Starting, Stopping	Update
Delete	Running, Stopped, Failed, or Failed Deleting	Scaling, Starting, Stopping	Delete

If an action is visible but disabled, refresh the scale group and check its status. The portal disables actions while the group is transitioning (Creating, Scaling, Starting, Stopping).

Resize Service

Use Resize Service to manually set the number of active nodes (the desired count / cardinality) — for example, to pre-warm capacity before a traffic event or a deployment.

The new value must be between the minimum and maximum nodes of the group.

To resize a scale group:

1. Open the Actions menu and select Resize Service.
2. In the Resize Service dialog, use the minus and plus controls to set the new active node count.
3. If you are increasing the count above the current desired value, choose how the minimum should behave:
   • Also update minimum desired nodes to N — raises the minimum so the elastic policy does not scale the group back down to the old minimum.
   • Keep minimum at N — leaves the minimum unchanged; the elastic policy may remove the extra nodes again when utilization is low.
4. Select Resize Pool.

note

Resize Pool stays disabled until you change the count away from the current value. The group moves through Scaling while nodes are added or removed.

Start

Use Start to bring a stopped scale group back online.

When you start a group, it returns to Running with all of your previously configured settings intact. The desired node count is set to the minimum nodes, and billing resumes.

To start a scale group:

1. Open the Actions menu and select Start.
2. In the Confirm Start Scale Group dialog, verify the scale group name.
3. Select Start scale group.
4. Wait for the status to move from Starting to Running.

Stop

Use Stop to halt a scale group without deleting it.

When stopped, the group's desired nodes are set to zero, all group nodes are removed, and billing for the scale group is paused. Your configuration (image, plan, policies, network, and security group) is preserved so you can start it again later.

note

Starting a stopped group again restores all settings, with one change: the desired node count comes back at the minimum nodes, not whatever it was before the stop.

To stop a scale group:

1. Open the Actions menu and select Stop.
2. In the Confirm Stop Scale Group dialog, read the notes — billing stops while stopped, and restarting brings desired nodes back to the minimum.
3. Select Stop scale group.
4. Wait for the status to move through Stopping to Stopped.

---

Delete

Use Delete to permanently terminate a scale group and all of its nodes.

danger

Deleting a scale group is destructive. All group nodes are terminated. Make sure you no longer need the running nodes or any data on them before confirming.

To delete a scale group:

1. Open the Actions menu and select Delete.
2. In the Delete Scale Group dialog, review the warning. If nodes are currently running, the dialog notes how many nodes are associated and reminds you that the group will be torn down.
3. Confirm the scale group name.
4. Select Delete Scale Group.
5. Wait for termination to complete.

After deletion, the saved image that was protected by this group can be deleted if it is no longer used elsewhere.
