astroctl infra kubernetes scale​

Scale a node group

Synopsis​

Scale a node group's minimum and maximum node count.

For complex updates (provider-specific settings, multiple changes), use: astroctl infra k8s update <cluster> -f update.yaml

astroctl infra kubernetes scale <cluster-name> [nodegroup-name] [flags]

Examples​

# List node groups in a cluster
astroctl infra k8s scale my-cluster --list

# Scale node group ng-1 to min 3, max 10
astroctl infra k8s scale my-cluster ng-1 --min 3 --max 10

# Scale with dry-run to preview
astroctl infra k8s scale my-cluster ng-1 --min 5 --max 20 --dry-run

# Scale only minimum (keeps current max)
astroctl infra k8s scale my-cluster ng-1 --min 3

# Scale only maximum (keeps current min)
astroctl infra k8s scale my-cluster ng-1 --max 10

# Scale with rolling update controls
astroctl infra k8s scale my-cluster ng-1 --min 5 --max 20 --max-surge 2 --max-unavailable 1

# Scale with percentage-based rolling update
astroctl infra k8s scale my-cluster ng-1 --min 10 --max 50 --max-surge 25% --max-unavailable 10%

Options​

      --dry-run                  Preview scaling without applying changes
  -h, --help                     help for scale
      --list                     List available node groups in this cluster
      --max int                  Maximum number of nodes (default -1)
      --max-surge string         Max nodes created above desired during rolling update (e.g. '2' or '25%')
      --max-unavailable string   Max nodes unavailable during rolling update (e.g. '1' or '10%')
      --min int                  Minimum number of nodes (default -1)
