EKS简易集群

本用例将会利用现有的“牌”（组件）来部署EKS集群

simple eks architecture

预装软件

步骤

确保aws cli工具配置正确，你可以通过以下命令检查

$ aws configure list
    Name                    Value             Type    Location
    ----                    -----             ----    --------
profile                <not set>             None    None
access_key     ****************XAWA shared-credentials-file
secret_key     ****************qEK5 shared-credentials-file
    region                us-east-2      config-file    ~/.aws/config

启动Dice后台程序如果你是第一次使用的话:

$ docker run -d -v ~/.aws:/root/.aws -p 9090:9090 docker.pkg.github.com/awslabs/aws-solutions-assembler/dice:latest

创建一个YAML配置文件并将其命名为simple-eks.yaml

apiVersion: mahjong.io/v1alpha1
kind: Deployment
metadata:
  name: eks-simple
  version: 0.1.0
spec:
  template:
    tiles:
      tileEks0005:
        tileReference: Eks0
        tileVersion: 0.0.5
        inputs:
          - name: clusterName
            inputValue: mahjong-cluster101
          - name: capacity
            inputValue: 3
          - name: capacityInstance
            inputValue: m5.large
          - name: version
            inputValue: 1.16
  summary:
    description:
    outputs:
      - name: EKS Cluster Name
        value: $(tileEks0005.outputs.clusterName)
      - name: Master role arn for EKS Cluster
        value: $(tileEks0005.outputs.masterRoleARN)
      - name: The API endpoint EKS Cluster
        value: $(tileEks0005.outputs.clusterEndpoint)
      - name: Instance type of worker node
        value: $(tileEks0005.outputs.capacityInstance)
      - name: Default capacity of worker node
        value: $(tileEks0005.outputs.capacity)

    notes: []

执行CDK引导程序cdk bootstrap aws://<your aws account>/<aws region>，例如：
```
cdk bootstrap aws://638198787577/us-east-2
```
该步骤只需要执行一次，以后无需再执行

部署到AWSmctl deploy -f ./simple-eks.yaml。如果一切顺利你讲会的得到一下结果:

$ mctl deploy -f ./simple-eks.yaml

...

[ℹ]  EKS Cluster Name = mahjong-cluster101
[ℹ]  Master role arn for EKS Cluster = arn:aws:iam::638198787577:role/Eks0StacktileEks0005-Eks0EksClusterMasterRole76926-D9OV6NASDYGC
[ℹ]  The API endpoint EKS Cluster = https://8F4AEE06CDA95AA5B9B82016B406F53B.gr7.us-east-2.eks.amazonaws.com
[ℹ]  Instance type of worker node = m5.large
[ℹ]  Default capacity of worker node = 3

一旦完成以上步骤后便可以检查您部署好的集群mahjong-cluster101

从部署日志中找到EKS集群的Master role

例如：

arn:aws:iam::638198787577:role/Eks0StacktileEks0005-Eks0EksClusterMasterRole76926-D9OV6NASDYGC

用以下命令创建保存k8s的登陆配置aws --region <region-code> eks update-kubeconfig --name <cluster_name> --role-arn arn:aws:iam::<aws_account_id>:role/<role_name>.
例如：
```
aws --region us-east-2 eks update-kubeconfig--name mahjong-cluster101 --role-arn arn:aws:iam::638198787577:role/Eks0StacktileEks0005-Eks0EksClusterMasterRole76926-D9OV6NASDYGC
```

检查您的集群

$ kubectl get svc
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   172.20.0.1   <none>        443/TCP   4h41m

请确保您正确安装了kubernetes-cli
