Illumina Innovates with Rancher and Kubernetes
When you provision a cluster hosted by an infrastructure provider, node templates are used to provision the cluster nodes. These templates use Docker Machine configuration options to define an operating system image and settings/parameters for the node. You can create node templates in two contexts:
When you create a node template, it is bound to your user profile. Node templates cannot be shared among users. You can delete stale node templates that you no longer user from your user settings.
Result: The template is configured. You can use the template later when you provision a node pool cluster.
Choose the node template that you want to edit and click the Vertical Ellipsis (…) > Edit.
Note: As of v2.2.0, the default active node drivers and any node driver, that has fields marked as password, are required to use cloud credentials. If you have upgraded to v2.2.0, existing node templates will continue to work with the previous account access information, but when you edit the node template, you will be required to create a cloud credential and the node template will start using it.
active
password
Edit the required information and click Save.
Result: The node template is updated. All node pools using this node template will automatically use the updated information when new nodes are added.
When creating new node templates from your user settings, you can clone an existing template and quickly update its settings rather than creating a new one from scratch. Cloning templates saves you the hassle of re-entering access keys for the cloud provider.
Result: The template is cloned and configured. You can use the template later when you provision a node pool cluster.
When you no longer use a node template, you can delete it from your user settings.
