Upload image
Oracle Cloud at the moment does not have a Talos official image. So you can use Bring Your Own Image (BYOI) approach.
Once the image is uploaded, set the Boot volume type to Paravirtualized mode.
OracleCloud has highly available NTP service, it can be enabled in Talos machine config with:
machine:
time:
servers:
- 169.254.169.254
Creating a Cluster via the CLI
Create a Load Balancer
Create a load balancer by issuing the commands shown below. Save the IP/DNS name, as this info will be used in the next step.
Create the Machine Configuration Files
Generating Base Configurations
Using the IP/DNS name of the loadbalancer created earlier, generate the base configuration files for the Talos machines by issuing:
$ talosctl gen config talos-k8s-oracle-tutorial https://<load balancer IP or DNS>:6443
created controlplane.yaml
created worker.yaml
created talosconfig
At this point, you can modify the generated configs to your liking.
Optionally, you can specify --config-patch with RFC6902 jsonpatches which will be applied during the config generation.
Validate the Configuration Files
Validate any edited machine configs with:
$ talosctl validate --config controlplane.yaml --mode cloud
controlplane.yaml is valid for cloud mode
$ talosctl validate --config worker.yaml --mode cloud
worker.yaml is valid for cloud mode
Create the Servers
Create the Control Plane Nodes
Create the control plane nodes with:
Create the Worker Nodes
Create the worker nodes with the following command, repeating (and incrementing the name counter) as many times as desired.
Bootstrap Etcd
To configure talosctl we will need the first control plane node's IP.
This can be found by issuing:
Set the endpoints and nodes for your talosconfig with:
talosctl --talosconfig talosconfig config endpoint <control-plane-1-IP>
talosctl --talosconfig talosconfig config node <control-plane-1-IP>
Bootstrap etcd on the first control plane node with:
talosctl --talosconfig talosconfig bootstrap
Retrieve the kubeconfig
At this point we can retrieve the admin kubeconfig by running:
talosctl --talosconfig talosconfig kubeconfig .
