Statuses

This section lists the statuses instance groups and instances (VMs) may have.
Note
The statuses of instances in groups differ from those of instances (VMs) in Compute Cloud.
Group statuses
| Status | Description |
|---|---|
STARTING |
Instance group is being created or started. The allowed actions with the instance group are: stop and delete. |
ACTIVE |
Instance group is running. Auto-healing and scaling will run in groups with this status if they were previously activated in the settings. The allowed actions with the group are update, pause, stop, and delete. |
PAUSED |
Instances in the group are running, but updates, auto-healing, and scaling are paused. The allowed actions with the instance group are resume processes and delete. Any significant changes to the group, such as resizing the group or reconfiguring instances, will not be applied until the processes are resumed. |
STOPPING |
Virtual machines and processes in the instance group are being stopped. The allowed actions with the instance group are start, update, and delete. Any significant changes to the group, such as resizing the group or reconfiguring instances, will only be applied after the group starts. |
STOPPED |
Virtual machines and processes in the instance group have been stopped. The allowed actions with the instance group are start, update, and delete. Any significant changes to the group, such as resizing the group or reconfiguring instances, will only be applied after the group starts. |
DELETING |
Instance group is being deleted. First, the instances in the group are deleted, and then the network load balancer target group (if any) is deleted, too. Finally, the entire instance group is deleted as well. The allowed action with the group is update (in case you need to specify a new service account ID). |
Statuses of instances in the group
| Status | Description |
|---|---|
CREATING_INSTANCE |
Instance is being created and started. Instance Groups will wait until the instance status in Compute Cloud switches to RUNNING. |
AWAITING_STARTUP_DURATION |
Instance has been created and is waiting for the user application to start for the specified startup period. Network traffic is not being sent to the instance. For automatic scaling, instances with this status are not taken into account. |
CHECKING_HEALTH |
Instance Groups is waiting for the results of its own health checks of the instance. You can limit the time in this status (see Settings for application health checks). |
OPENING_TRAFFIC |
If an instance group is integrated with the load balancing service, Instance Groups waits until the instance passes a health check from the load balancer and is ready to accept traffic from it. You can limit the time in this status (see Health checks from load balancers). If the integration is disabled, the status is skipped. |
AWAITING_WARMUP_DURATION |
Instance receives traffic, but no metrics for automatic scaling are read from it during the specified time interval. |
RUNNING_ACTUAL |
Instance is running and receiving network traffic. User applications are running. |
RUNNING_OUTDATED |
Instance is running but will soon be updated or deleted. |
CLOSING_TRAFFIC |
Instance is being removed from the network load balancer's target group. Network traffic from the load balancer to the instance is being stopped. |
STOPPING_INSTANCE |
Instance is being stopped. |
STOPPED |
Instance has been stopped. You are not charged for instances with this status. |
STARTING_INSTANCE |
Instance is being started. Instance Groups will wait until the instance status in Compute Cloud switches to RUNNING. |
UPDATING_INSTANCE |
Basic parameters or metadata of the instance are being updated. |
DELETING_INSTANCE |
Instance is being deleted. |
PREPARING_RESOURCES |
Instance is being prepared for use with new instances. For example, the disks may be remained or their volume may be changed. |
DELETED |
Instance has been deleted. All data and resources associated with this instance are saved for later use. |
Lifecycle of instances in a group
The chart below shows how the instance status changes during the lifecycle:
: Instance Groups performs an action on an instance.
