Enterprise Kubernetes, delivered

Tectonic ships with CoreOS's signature automated operations, runs multi-cloud, and is the fastest, most secure path to Kubernetes.

Scaling Tectonic AWS clusters

To scale worker nodes, adjust tectonic_worker_count in terraform.tfvars.

Use the plan command to check your syntax:

$ terraform plan \
  -var-file=build/${CLUSTER}/terraform.tfvars \
  -target module.workers \
  platforms/aws

Once you are ready to make the changes live, use apply:

$ terraform apply \
  -var-file=build/${CLUSTER}/terraform.tfvars \
  -target module.workers \
  platforms/aws

The new nodes should automatically show up in the Tectonic Console shortly after they boot.
