1 - Kubernetes Engine

1.1 - Overview

Service Overview

Kubernetes Engine is a service that provides lightweight virtual computing, containers, and a Kubernetes cluster to manage them. Users can leverage a Kubernetes environment without complex preparation by installing, operating, and maintaining the Kubernetes Control Plane.

Features

• Standard Kubernetes Environment Setup: You can use a standard Kubernetes environment without additional configuration through the built-in Kubernetes Control Plane. It is compatible with applications in other standard Kubernetes environments, allowing you to use standard Kubernetes applications without modifying code.

• Easy Kubernetes Deployment: provides secure communication between the worker node (Worker Node) and the managed control plane, and quickly provisions worker nodes so users can focus on building applications on the provided container environment.

• Convenient Kubernetes Management: For enterprise environments, we provide various management features to conveniently use the created Kubernetes clusters, including cluster information lookup and management via a dashboard, namespace management, and workload management functions.

Service Diagram

Provided features

Kubernetes Engine provides the following features.

• Cluster Management: You can create and manage clusters to use the Kubernetes Engine service. After creating a cluster, you can add services needed for operation such as nodes, namespaces, and workloads.
• Node Management: A node is a set of machines that run containerized applications. Every cluster must have at least one worker node to deploy applications. Nodes can be used by defining node pools. Nodes belonging to a node pool must have the same server type, size, and OS image, and creating multiple node pools enables flexible deployment strategies.
• Namespace Management: A namespace is a logical partition within a Kubernetes cluster and is used to specify access permissions or resource usage limits per namespace.
• Workload Management: A workload is an application running on Kubernetes Engine. After creating a namespace, you can add or delete workloads. Workloads are created and managed per item such as Deployment, Pod, StatefulSet, DaemonSet, Job, and CronJob.
• Service and Ingress Management: A service is an abstraction that exposes applications running in a set of pods as a network service, and an ingress is used to expose HTTP and HTTPS paths from outside the cluster to inside the cluster. After creating a namespace, you can create or delete services, endpoints, ingresses, and ingress classes.
• Storage Management: You can create and manage the storage to be used when using Kubernetes Engine. Storage is created and managed per PVC, PV, and StorageClass items.
• Configuration Management: When you need to manage values that change inside containers across multiple environments such as Dev/Prod, creating separate images to handle them via environment variables is inconvenient and wasteful. In Kubernetes, you can manage environment variables or configuration settings as variables that can be changed externally and injected when a Pod is created; at that point you can use ConfigMaps and Secrets.
• Permission Management: When multiple users access a Kubernetes cluster, you can assign permissions per specific API or namespace to define the access scope. By applying Kubernetes’ role-based access control (RBAC) feature, you can set permissions for clusters or namespaces. You can create and manage ClusterRoles, ClusterRoleBindings, Roles, and RoleBindings.

Component

control plane

Control Plane is the component that serves as the master node in the Kubernetes Engine service. The master node is the cluster’s management node, responsible for managing the other nodes in the cluster. A cluster is the basic creation unit of the Kubernetes Engine service and is used for managing node pools, objects, controllers, etc., that belong to it. Users configure the cluster name (cluster name), control plane, network, File Storage, and then create node pools within the cluster for use. The master node assigns work to the cluster, monitors node status, and handles data communication between nodes.

The cluster name creation rules are as follows.

• It must start with a letter and can be set using letters, numbers, and special characters (-) within 3 to 30 characters.
• It must not duplicate an already existing cluster name.

worker node

The worker node (Worker Node) is a compute node in the cluster that performs tasks. It receives task assignments from the cluster’s master node, executes them, and reports the results back to the master node. All nodes created within a node pool and namespace serve as worker nodes.

The rules for creating a node pool, which is a collection of worker nodes, are as follows.

• A node pool must contain at least one node for the application deployment to be possible.
• A maximum of 100 nodes can be created within a node pool.
• Since the maximum number of nodes is 100, you can freely create up to 100 nodes—for example, with 100 node pools you get 1 node per pool, and with 50 node pools you get 2 nodes per pool.
• It is possible to configure block storage attached to a node pool.
• You can configure the server type, size, and OS image for nodes in a node pool, and they must all be identical.
• Through the Auto-Scaling service, you can configure automatic scaling and shrinking of node pools according to the requirements of the deployed application.

Preliminary Service

This is a list of services that must be pre-configured before creating the service. Please refer to the guide provided for each service for details and prepare in advance.

1.1.1 - Monitoring Metrics

Kubernetes Engine monitoring metrics

The table below shows the monitoring metrics of Kubernetes Engine that can be viewed through Cloud Monitoring. For detailed usage of Cloud Monitoring, refer to the Cloud Monitoring guide.

1.1.2 - ServiceWatch Metrics

Kubernetes Engine sends metrics to ServiceWatch. The metrics provided by default monitoring are data collected at a 1‑minute interval.

Basic Metrics

The following are the basic metrics for the Kubernetes Engine namespace.

The metrics whose names are displayed in bold below are the metrics selected as key metrics among the default metrics provided by Kubernetes Engine. Key metrics are used to configure service dashboards that are automatically generated for each service in ServiceWatch.

Each metric indicates through the user guide which statistical values are meaningful when viewing that metric, and among the meaningful statistics, the values displayed in bold are the primary statistics. In the service dashboard, you can view key metrics using these primary statistical values.

1.3 - Kubernetes Engine Usage Guide

Provides a guide for using Kubernetes Engine.

Kubernetes Engine Utilization Guide

In the Kubernetes Engine usage, the following features are described. For more details, refer to the guide.

1.3.1 - Access Cluster

kubectl Installation and Usage

After creating a Kubernetes Engine service, you can use the Kubernetes command-line tool kubectl to execute commands against your Kubernetes cluster. With kubectl, you can deploy applications, inspect and manage cluster resources, and view logs. You can find how to install and use kubectl in the official Kubernetes documentation.

To access a Kubernetes cluster with kubectl, you need a kubeconfig file that contains the Kubernetes server address and authentication information.

Kubernetes Engine supports authentication via admin certificate kubeconfig and user authentication key kubeconfig.

Admin certificate kubeconfig

This kubeconfig uses the admin certificate as the authentication method when accessing the Kubernetes API.

Download admin kubeconfig

Kubernetes Engine > Cluster List > Cluster Details > Admin kubeconfig download Click the button to download the kubeconfig file.

Use admin kubeconfig

User authentication key kubeconfig

This kubeconfig uses the user’s Open API authentication key as the credential when accessing the Kubernetes API.

User kubeconfig download

Kubernetes Engine > Cluster List > Cluster Details > User kubeconfig Download Click the button to download the kubeconfig file.

Add authentication key token to the user kubeconfig file

Below is an example of a user kubeconfig file. To use the kubeconfig file, you must add the authentication key token (AUTHKEY_TOKEN) information to the token field inside the file.

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0t...
    server: https://my-cluster-a1c3e.ske.xxx.samsungsdscloud.com:6443
  name: my-cluster-a1c3e
contexts:
- context:
    cluster: my-cluster-a1c3e
    user: jane.doe
  name: jane.doe@my-cluster-a1c3e
current-context: jane.doe@my-cluster-a1c3e
kind: Config
preferences: {}
users:
- name: jane.doe
  user:
    token: <AUTHKEY_TOKEN> #### Writing required

apiVersion: v1
clusters:

    certificate-authority-data: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0t...
    server: https://my-cluster-a1c3e.ske.xxx.samsungsdscloud.com:6443
  name: my-cluster-a1c3e

current-context: jane.doe@my-cluster-a1c3e
kind: Config
preferences: {}
users:
- name: jane.doe
  user:
    token: <AUTHKEY_TOKEN> #### Writing required

AUTHKEY_TOKEN can be generated by concatenating the ACCESS_KEY and SECRET_KEY of the authentication key with a colon (:) and then Base64 encoding it. The following is an example of creating an AUTHKEY_TOKEN in a Linux environment.

$ ACCESS_KEY=5df418813aed051548a72f4a814cf09e
$ SECRET_KEY=6ba7b810-9dad-11d1-80b4-00c04fd430c8
$ AUTHKEY_TOKEN=$(echo -n "$ACCESS_KEY:$SECRET_KEY" | base64 -w0)
$ echo $AUTHKEY_TOKEN
NWRmNDE4ODEzYWVkMDUxNTQ4YTcyZjRhODE0Y2YwOWU6NmJhN2I4MTAtOWRhZC0xMWQxLTgwYjQtMDBjMDRmZDQzMGM4r

User kubeconfig execution example

You can view an example of executing the user kubeconfig.

When access is blocked by access control or a firewall

$ kubectl --kubeconfig=user-kubeconfig.yaml get namespaces
Unable to connect to the server: dial tcp 123.123.123.123:6443: i/o timeout

$ kubectl --kubeconfig=user-kubeconfig.yaml get namespaces
Unable to connect to the server: dial tcp 123.123.123.123:6443: i/o timeout

When authentication fails because the AUTHKEY_TOKEN does not match

$ kubectl --kubeconfig=user-kubeconfig.yaml get namespaces
error: You must be logged in to the server (Unauthorized)

$ kubectl --kubeconfig=user-kubeconfig.yaml get namespaces
error: You must be logged in to the server (Unauthorized)

AUTHKEY_TOKEN when authentication succeeds

$ kubectl --kubeconfig=user-kubeconfig.yaml get namespaces
...
kube-node-lease    Active 10d
kube-public        Active 10d
kube-system        Active 10d

$ kubectl --kubeconfig=user-kubeconfig.yaml get namespaces
...
kube-node-lease    Active 10d
kube-public        Active 10d
kube-system        Active 10d

AUTHKEY_TOKEN Authentication succeeded but lacks permission

$ kubectl --kubeconfig=user-kubeconfig.yaml get nodes
Error from server (Forbidden): nodes is forbidden: User "jane.doe" cannot list resource "nodes" in API group "" at the cluster scope

$ kubectl --kubeconfig=user-kubeconfig.yaml get nodes
Error from server (Forbidden): nodes is forbidden: User "jane.doe" cannot list resource "nodes" in API group "" at the cluster scope

1.3.2 - Authentication and Authorization

Kubernetes Engine applies Kubernetes authentication and RBAC authorization features. It explains how Kubernetes authentication and authorization functions integrate with Kubernetes Engine and IAM.

Kubernetes authentication and authorization

Describes Kubernetes authentication and RBAC authorization features.

Authentication

The Kubernetes API server obtains the information required for authenticating a user (User) or a service account (ServiceAccount) from certificates or authentication tokens, and then carries out the authentication process.

Authorization

The Kubernetes API server uses the user information obtained through the authentication process to verify, via RBAC-related objects, whether the user has permission for the requested operation. RBAC-related objects come in four types as follows.

Roll

Kubernetes defines several cluster roles by default. Some of those cluster roles do not include the prefix (system:). These are cluster roles intended for user use. This includes a superuser role (cluster-admin) applied to the entire cluster using a ClusterRoleBinding, and roles (admin, edit, view) applied to a specific namespace using a RoleBinding.

If necessary, you can define additional roles (or cluster roles) beyond the default cluster role, as shown below.

# A role that grants permission to view pods in the "default" namespace.
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  namespace: default
  name: pod-reader
rules:
- apiGroups: [""]
  resources: ["pods"]
  verbs: ["get", "list", "watch"]

# A role that grants permission to view pods in the "default" namespace.
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  namespace: default
  name: pod-reader
rules:
- apiGroups: [""]
  resources: ["pods"]
  verbs: ["get", "list", "watch"]

# Cluster role that grants permission to view nodes
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: node-reader
rules:
- apiGroups: [""]
  resources: ["nodes"]
  verbs: ["get", "list", "watch"]

# Cluster role that grants permission to view nodes
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: node-reader
rules:
- apiGroups: [""]
  resources: ["nodes"]
  verbs: ["get", "list", "watch"]

Role Binding

To manage access to the Kubernetes Engine using Samsung Cloud Platform IAM, you need to understand the relationship between Kubernetes role bindings and IAM. The subjects of a role binding (or cluster role binding) may include individual users (User) or groups (Group).

• User corresponds to the Samsung Cloud Platform username, and Group corresponds to the IAM user group name, respectively.

For RoleBinding/ClusterRoleBinding, subjects.kind can be set to one of the following.

• User: Samsung Cloud Platform is connected to individual users.
• Group: Connected to the Samsung Cloud Platform IAM user group.

The subjects.name of a role binding/cluster role binding can be specified as follows. If the user is a User: individual Samsung Cloud Platform username (e.g., jane.doe) For a group: Samsung Cloud Platform IAM user group name (e.g., ReadPodsGroup)

In this way, the IAM user group is linked to the group defined in the RoleBinding (or ClusterRoleBinding) of the Kubernetes Engine cluster. It is also granted permission to perform the API actions included in the Role (or ClusterRole) associated with the group.

Example) role binding read-pods #1

The example of writing User (individual Samsung Cloud Platform user) in a role binding is as follows.

# This role binding allows the user "jane.doe" to view pods in the "default" namespace.
# The namespace must have a role named "pod-reader".
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: read-pods
  namespace: default
roleRef:
  # The "roleRef" specifies the link to a Role or ClusterRole.
  kind: Role       # Must be Role or ClusterRole.
  name: pod-reader # Must match the name of the Role or ClusterRole you want to bind to.
  apiGroup: rbac.authorization.k8s.io
subjects:
# You can specify one or more "target (subject)".
- kind: User
  name: jane.doe
  apiGroup: rbac.authorization.k8s.io

# This role binding allows the user "jane.doe" to view pods in the "default" namespace.
# The namespace must have a role named "pod-reader".
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: read-pods
  namespace: default
roleRef:
  # The "roleRef" specifies the link to a Role or ClusterRole.
  kind: Role       # Must be Role or ClusterRole.
  name: pod-reader # Must match the name of the Role or ClusterRole you want to bind to.
  apiGroup: rbac.authorization.k8s.io
subjects:
# You can specify one or more "target (subject)".
- kind: User
  name: jane.doe
  apiGroup: rbac.authorization.k8s.io

When a role binding like the above is created in the cluster, a user whose username is jane.doe is granted permission to perform the API actions defined in the pod-reader role.

Example) role binding read-pods #2

The example of creating a group (IAM user group) in role binding is as follows.

# This role binding allows users in the "ReadPodsGroup" group to view pods in the "default" namespace.
# The namespace must have a role called "pod-reader".
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: read-pods
  namespace: default
roleRef:
  kind: Role
  name: pod-reader
  apiGroup: rbac.authorization.k8s.io
subjects:
# You can specify one or more "target (subject)".
- kind: Group
  name: ReadPodsGroup
  apiGroup: rbac.authorization.k8s.io

# This role binding allows users in the "ReadPodsGroup" group to view pods in the "default" namespace.
# The namespace must have a role called "pod-reader".
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: read-pods
  namespace: default
roleRef:
  kind: Role
  name: pod-reader
  apiGroup: rbac.authorization.k8s.io
subjects:
# You can specify one or more "target (subject)".
- kind: Group
  name: ReadPodsGroup
  apiGroup: rbac.authorization.k8s.io

If a role binding like the above is created in the cluster, users in the IAM user group ReadPodsGroup are granted permission to perform the API actions defined in the role pod-reader.

Example) ClusterRoleBinding read-nodes

# This cluster role binding allows users in the "ReadNodesGroup" group to view nodes.
# A cluster role named "node-reader" must exist.
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: read-nodes
roleRef:
  kind: ClusterRole
  name: node-reader
  apiGroup: rbac.authorization.k8s.io
subjects:
- kind: Group
  name: ReadNodesGroup
  apiGroup: rbac.authorization.k8s.io

# This cluster role binding allows users in the "ReadNodesGroup" group to view nodes.
# A cluster role named "node-reader" must exist.
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: read-nodes
roleRef:
  kind: ClusterRole
  name: node-reader
  apiGroup: rbac.authorization.k8s.io
subjects:
- kind: Group
  name: ReadNodesGroup
  apiGroup: rbac.authorization.k8s.io

When a cluster role binding like the above is created in the cluster, users belonging to the IAM user group ReadNodesGroup are granted permission to perform the API actions defined in the cluster role node-reader.

Predefined roles and role bindings for Samsung Cloud Platform

In the Kubernetes Engine of Samsung Cloud Platform, the cluster role bindings scp-cluster-admin, scp-view, scp-namespace-view, and the cluster role scp-namespace-view are predefined. The table below shows the predefined roles and role bindings for Samsung Cloud Platform and the relationships of Samsung Cloud Platform users. Here, the cluster roles cluster-admin and view are predefined within the Kubernetes cluster. For more details, see role.

• According to the cluster role binding scp-cluster-admin, the Kubernetes Engine service creator is granted cluster admin privileges.
