| additional_tags | Additional tags to apply to node group | map |
{ |
no |
| asg_desired_capacity | Desired worker capacity in the autoscaling group and changing its value will not affect the autoscaling group's desired capacity because the cluster-autoscaler manages up and down scaling of the nodes. Cluster-autoscaler add nodes when pods are in pending state and remove the nodes when they are not required by modifying the desirec_capacity of the autoscaling group. Although an issue exists in which if the value of the asg_min_size is changed it modifies the value of asg_desired_capacity. | number |
1 |
no |
| asg_max_size | Maximum worker capacity in the autoscaling group. | number |
1 |
no |
| asg_min_size | Minimum worker capacity in the autoscaling group. NOTE: Change in this paramater will affect the asg_desired_capacity, like changing its value to 2 will change asg_desired_capacity value to 2 but bringing back it to 1 will not affect the asg_desired_capacity. | number |
1 |
