Upgrading Talos

Locally update the value of local.version in platform-layer/terraform/talos-cluster.tf with the appropriate target version.
```
locals {
    ...
    talos_install_version = "X.X.X"
    ...
}
```
Note

Talos requires step-upgrading to the latest patch of the current minor release before the latest patch of the next minor version. Upgrading from v1.10.2 to v.1.11.3, for example, would require first upgrading to v1.10.7 before upgrading to v1.11.3.

Generate and display the new Terraform outputs

cd platform-layer/terraform/
TF_WORKSPACE=homeops-pf-layer terraform init
TF_WORKSPACE=homeops-pf-layer terraform plan -refresh-only

Upgrade one of the Talos nodes with the new installer image from the Terraform output

talosctl upgrade \
 --preserve \
 --image 'factory.talos.dev/nocloud-installer/88d1f7a5c4f1d3aba7df787c448c1d3d008ed29cfb34af53fa0df4336a56040b:v1.10.7' \
 --nodes '192.168.20.X'

Repeat step 5 for each node in the cluster
Repeat steps 1-6, step-upgrading until the final target version is reached
Run terraform apply to view and reconcile any changes
```
TF_WORKSPACE=homeops-pf-layer terraform apply
```
Commit, push, and merge the changes
