Increase the size of an AWS EBS volume

To increase the size of an AWS EBS volume, we need to increase the size of the EBS volume in the tfvars file of the hub:

For example, to increase the size of the EBS volume used by jupyterhub-home-nfs for the staging hub in the nasa-veda cluster, we would increase the size parameter in the ebs_volumes block for the staging hub in the tfvars file for the nasa-veda cluster.

After updating the tfvars file, we need to plan and apply the changes using terraform:

cd terraform/aws
terraform plan -var-file=projects/$CLUSTER_NAME.tfvars
terraform apply -var-file=projects/$CLUSTER_NAME.tfvars

Note

The size of an EBS volume can only be increased, not decreased.
