1 - Managing Nodes

A node is a set of machines that run containerized applications. A cluster must have at least one node to deploy an application. Nodes can be defined in a node pool for use. Nodes belonging to a node pool must have the same server type, size, and OS image, and flexible deployment strategies can be established by creating multiple node pools.

After creating a Kubernetes Engine cluster, add a node pool and modify or delete it as needed.

Add node pool

A node refers to a machine that runs containerized applications, and at least one node is required to deploy applications in a Kubernetes cluster. After the Kubernetes Engine cluster has been created, add a node pool from the details page.

• In Kubernetes Engine, you can define and use a node pool, which is a set of nodes. * Since the nodes in a node pool use the same server type, size, and OS image, users can devise flexible deployment strategies by using multiple node pools.

To add a node pool, follow these steps.

1. All Services > Container > Kubernetes Engine Click the menu. 1. Go to the Service Home page of Kubernetes Engine.
2. On the Service Home page, click the Cluster menu. 2. Navigate to the Cluster List page.

Auto-scaling node pools

Node pool auto-scaling is a feature that automatically adjusts the number of node pools by adding new nodes to a specified node pool or removing existing nodes based on workload demands. This feature operates based on the node pool.

• When automatically scaling a node pool up or down, it is adjusted based on the resource requests of the pods running on the node pool’s nodes rather than the actual resource utilization, and it periodically checks the status of pods and nodes and executes automatic scaling operations.

To set up automatic scaling for a node pool, follow these steps.

     • When all pods running on a node can be scheduled on another node (there must be no pods subject to PDB restrictions, etc.)
   • When using automatic node pool scaling, to prevent deletion caused by node reduction, add the following annotation to the node.
     • cluster-autoscaler.kubernetes.io/scale-down-disabled: “true”

When multiple users access a Kubernetes cluster, you can assign permissions for specific APIs or namespaces to define access scopes. You can apply Kubernetes’ role-based access control (RBAC) feature to set permissions for each cluster or namespace. You can create and manage ClusterRoles, ClusterRoleBindings, Roles, and RoleBindings.

Managing Cluster Roles

You can set and manage access permissions at the cluster level. You can also set permissions for APIs or resources that are not limited to a namespace.

Create ClusterRole

To create a cluster role, follow these steps.

1. Click the All Services > Container > Kubernetes Engine menu. 1. Go to the Service Home page of Kubernetes Engine.
2. On the Service Home page, click Cluster Role under the Permissions menu. 2. Go to the Cluster role list page.
3. On the Cluster Role List page, select the cluster and namespace from the gear button at the top left, then click Create Object.
4. Enter the object information in the Object Creation Popup and click the Confirm button.

Check detailed information of the cluster role

To view detailed information about the cluster role, follow these steps.

An empty set means everything is allowed Verbs: Verbs are the API actions used in resource requests such as get, list, create, update, patch, watch, delete, deletecollection For more information, see the Kubernetes official documentation > API Verbs
