Amazon EKS创建S3数据存储卷

1、创建适用于 Amazon S3的IAM策略
创建存储桶amazoneks

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "s3express:CreateSession",
            "Resource": "arn:aws:s3express:ap-east-1:XXXXX:bucket/amazoneks--ap-east-1--x-s3"
        }
    ]
}

创建策略

{
   "Version": "2012-10-17",
   "Statement": [
        {
            "Sid": "MountpointFullBucketAccess",
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::amazoneks"
            ]
        },
        {
            "Sid": "MountpointFullObjectAccess",
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:AbortMultipartUpload",
                "s3:DeleteObject"
            ],
            "Resource": [
                "arn:aws:s3:::amazoneks/*"
            ]
        }
   ]
}

策略命名AmazonS3CSIDriverPolicy
2、创建 IAM 角色
在 Select trusted entity（选择受信任的实体）页面上操作
在这里插入图片描述

在 Add permissions（添加权限）页面上筛选刚刚创建的AmazonS3CSIDriverPolicy操作
在这里插入图片描述
在 Name, review, and create（命名、查看和创建）页面命名AmazonEKS_S3_CSI_DriverRole

编辑受信任实体

"oidc.eks.region-code.amazonaws.com/id/EXAMPLED539D4633E53DE1B71EXAMPLE:aud": "sts.amazonaws.com"

在上一行末尾添加逗号，然后在逗号后添加下一行。将 region-code 替换为集群所在的 AWS 区域。将 EXAMPLED539D4633E53DE1B71EXAMPLE 替换为集群的 OIDC 提供商 ID。

"oidc.eks.region-code.amazonaws.com/id/EXAMPLED539D4633E53DE1B71EXAMPLE:sub": "system:serviceaccount:kube-system:s3-csi-*"

将 Condition 运算符从 “StringEquals” 变更为 “StringLike”。

{
	"Version": "2012-10-17",
	"Statement": [
		{
			"Effect": "Allow",
			"Principal": {
				"Federated": "arn:aws:iam::XXXXXXX:oidc-provider/oidc.eks.ap-east-1.amazonaws.com/id/4BA13F545074880CE8E57DAB11B436B1"
			},
			"Action": "sts:AssumeRoleWithWebIdentity",
			"Condition": {
				"StringLike": {
					"oidc.eks.ap-east-1.amazonaws.com/id/4BA13F545074880CE8E57DAB11B436B1:aud": "sts.amazonaws.com",
					"oidc.eks.ap-east-1.amazonaws.com/id/4BA13F545074880CE8E57DAB11B436B1:sub": "system:serviceaccount:kube-system:s3-csi-*"
				}
			}
		}
	]
}

3、安装适用于 Amazon S3 的 Mountpoint CSI 驱动程序

eksctl create addon --name aws-mountpoint-s3-csi-driver --cluster eks-test --service-account-role-arn arn:aws:iam::XXXXXXX:role/AmazonEKS_S3_CSI_DriverRole --force
2024-05-04 16:30:24 [ℹ]  Kubernetes version "1.29" in use by cluster "eks-test"
2024-05-04 16:30:24 [ℹ]  using provided ServiceAccountRoleARN "arn:aws:iam::XXXXXXX:role/AmazonEKS_S3_CSI_DriverRole"
2024-05-04 16:30:24 [ℹ]  creating addon
2024-05-04 16:31:20 [ℹ]  addon "aws-mountpoint-s3-csi-driver" active

查询驱动

# kubectl describe csidriver  s3.csi.aws.com
Name:         s3.csi.aws.com
Namespace:    
Labels:       app.kubernetes.io/component=csi-driver
              app.kubernetes.io/instance=aws-mountpoint-s3-csi-driver

3、创建S3 pv
pv yaml文件

# cat s3-pv.yaml 
apiVersion: v1
kind: PersistentVolume
metadata:
  name: s3-pv
spec:
  capacity:
    storage: 120Gi # ignored, required
  accessModes:
    - ReadWriteMany # supported options: ReadWriteMany / ReadOnlyMany
  mountOptions:
    - allow-delete
    - region ap-east-1
  csi:
    driver: s3.csi.aws.com # required
    volumeHandle: s3-csi-driver-volume
    volumeAttributes:
      bucketName: amazoneks

创建pv

[root@ip-10-0-7-211 ~]# kubectl apply -f s3-pv.yaml 
persistentvolume/s3-pv created

查询pv

# kubectl get pv s3-pv
NAME    CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM              STORAGECLASS   VOLUMEATTRIBUTESCLASS   REASON   AGE
s3-pv   120Gi      RWX            Retain           Bound    default/s3-claim                  <unset>                          2m30s

4、创建S3 pvc
pvc yaml文件

# cat s3-pvc.yaml 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: s3-claim
spec:
  accessModes:
    - ReadWriteMany # supported options: ReadWriteMany / ReadOnlyMany
  storageClassName: "" # required for static provisioning
  resources:
    requests:
      storage: 120Gi # ignored, required
  volumeName: s3-pv

创建pv3

[root@ip-10-0-7-211 ~]# kubectl apply -f s3-pvc.yaml 
persistentvolumeclaim/s3-claim created

查询pvc

# kubectl get pvc s3-claim
NAME       STATUS   VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS   VOLUMEATTRIBUTESCLASS   AGE
s3-claim   Bound    s3-pv    120Gi      RWX                           <unset>                 5m48s

5、验证
nginx yaml配置文件

          volumeMounts:
            - mountPath: /usr/share/nginx/html/
              name: volume-xankc
              subPath: html
      volumes:
        - name: volume-xankc
          persistentVolumeClaim:
            claimName: s3-claim

此时在S3上看得到我们的内容
在这里插入图片描述
tomcat测试
挂载日志文件，我们在S3上查看是否有新文件生成即可

          volumeMounts:
            - mountPath: /usr/local/tomcat/logs
              name: volume-zcb56
              subPath: htm/tomcat/
      volumes:
        - name: volume-zcb56
          persistentVolumeClaim:
            claimName: s3-claim
