海外TECH	DEV Community	Write your Kubernetes Infrastructure as Go code - Combine cdk8s with AWS CDK	https://dev.to/abhirockzz/write-your-kubernetes-infrastructure-as-go-code-combine-cdk8s-with-aws-cdk-3705	Write your Kubernetes Infrastructure as Go code Combine cdks with AWS CDKIn an earlier blog post you saw how to use cdks with AWS Controllers for Kubernetes also known as ACK thanks to the fact that you can import existing Kubernetes Custom Resource Definitions using cdks This made is possible to deploy DynamoDB along with a client application from using cdks and Kubernetes But what if you continue using AWS CDK for AWS infrastructure and harness the power cdks and cdks plus to define Kubernetes resources using regular code Thanks to the native integration betweenthe AWS EKS module and cdks you can have the best of both worlds The goal of this blog post is to demonstrate that with a few examples We will start off with a simple nginx based example before moving on to a full fledged application stack including DynamoDB etc Both will be using the Go programming language which is well supported in AWS CDK as well as cdks All the code discussed in this blog is available in this GitHub repo PrerequisitesTo follow along step by step in addition to an AWS account you will need following CLIs AWS CLI cdks CLI and kubectl Also dont forget to install AWS CDK the Go programming language v or above as well as Docker if you don t have them already Keeping it simple with Nginx on EKSAs with most things in life there are two ways the easy way or the hard way You will see both of them Let s try things out first see them working and then look at the code To start off clone the repo and change to the right directory git clone cd cdks for go developers part cdk eks cdks cdk cdks nginx eksTo setup everything all you need is a single command cdk deployyou can also use cdk synth to generate and inspect the Cloud Formation template firstYou will be prompted to confirm Once you do that the process will kick off it will take some time since lots of AWS resources will be created including VPC EKS cluster etc Feel free to check the AWS Cloud Formation console to track the progress Once the process is complete you need to connect to the EKS cluster using kubectl The command required for this will be available as a result of the cdk deploy process in the terminal or you can refer to the Outputs section of the AWS Cloud Formation stack Once you ve configured kubectl to point to your EKS cluster you can check the Nginx Deployment and Service kubectl get deployment outputNAME READY UP TO DATE AVAILABLE AGEnginx deployment cdks mnginx deployment cdk mYou will see that two Deployments have been created more on this soon Similiarly if you check the Service kubectl get svc you should see two of them nginx service cdk and nginx service cdks To access Nginx pick the EXTERNAL IP of any of the two Services For example APP URL kubectl get service nginx service cdk o jsonpath status loadBalancer ingress hostname echo APP URL to access nginx notice we are using port curl i http APP URL If you get a Could not resolve host error while accessing the LB URL wait for a minute or so and re try Behind the scenesLet s look at the code now this will clarify why we have two Nginx Deployments Thanks to AWS CDK VPC creation is a one liner with awsec NewVpc function and creating an EKS cluster isn t too hard either func NewNginxOnEKSStack scope constructs Construct id string props CdkStackProps awscdk Stack vpc awsec NewVpc stack jsii String demo vpc nil eksSecurityGroup awsec NewSecurityGroup stack jsii String eks demo sg amp awsec SecurityGroupProps

awsec InstanceType Of awsec InstanceClass BURSTABLE awsec InstanceSize SMALL DefaultCapacityType awseks DefaultCapacityType NODEGROUP OutputConfigCommand jsii Bool true EndpointAccess awseks EndpointAccess PUBLIC Nginx on Kubernetes the hard way Now we look at two different ways of creating Nginx starting with the hard way In this case we use AWS CDK not cdks to define the Deployment and Service resources func deployNginxUsingCDK eksCluster awseks Cluster appLabel map string string app jsii String nginx eks cdk deployment map string interface apiVersion jsii String apps v kind jsii String Deployment metadata map string string name jsii String nginx deployment cdk spec map string interface replicas jsii Number selector map string map string string matchLabels appLabel template

jsii String LoadBalancer ports map string float port jsii Number targetPort jsii Number selector appLabel eksCluster AddManifest jsii String app deployment amp service amp deployment Finally to create this in EKS we invoke AddManifest think of its like the programmatic equivalent of kubectl apply This works but there are a few gaps in this approach We are not able to reap the benefits of Go which is a strongly typed language That s because the API is loosely typed thanks to map string interface everywhere This makes it very error prone I made a few mistakes too The verbosity is apparent as well It seems as if we are writing YAML in Go not too much of an improvement Is there a better way Let s look at the second function deployNginxUsingCDKs by the name its obvious that we used cdks not just CDK func deployNginxUsingCDKs eksCluster awseks Cluster app cdks NewApp nil eksCluster AddCdksChart jsii String nginx eks chart NewNginxChart app nginx cdks nil nil This looks too easy to to be true But it s made possible due to the inter operability between CDK and cdks What this implies is that you can use define Kubernetes resources using cdks Charts and apply them to an EKS cluster created with CDK this makes it sort of a hybrind system The hero of our story is AddCdksChart function which accepts a constructs Construct remember everything is a construct In this case the Construct happens to be a cdks Chart thats returned by NewNginxChart function so lets take a look at that func NewNginxChart scope constructs Construct id string props MyChartProps cdks Chart dep

ServiceType cdksplus ServiceType LOAD BALANCER Ports amp cdksplus ServicePort Port jsii Number TargetPort jsii Number return chart If you have worked with cdks and Go or read some of my previous blogs on this topic this should look familiar a strongly typed compact and expressive API I don t even need to walk you through this since its so readable we use cdks plus to create a Nginx Deployment add the container info and finally expose it via a Service so that we can access the Nginx from outside of EKS This was a simple enough example to help bring out difference between the two approaches The next scenario is different in addition to the EKS cluster it has DynamoDB along with a URL shortener application that will be deployed to EKS End to end example DynamoDB along with an application on EKSInstead of creating a new EKS cluster from scratch we will re use the existing cluster created as a result of the previous example this is a good opportunity to take a look at how you can reference an existing EKS cluster in your CDK code As expected we need to create DynamoDB table as well Just like in the previous example let s try out the solution first Change into the right directory first cd part cdk eks cdks cdk cdks dynamodb app eksSince the URL shortener application has to make API calls to DynamoDB we need to configure IAM Roles for Service Accounts also known as IRSA Refer to Define IAM roles for the applicationStart by creating a Kubernetes Service Account kubectl apply f lt lt EOFapiVersion vkind ServiceAccountmetadata name eks dynamodb app saEOFTo confirm kubectl get serviceaccount eks dynamodb app sa o yamlSet your AWS Account ID and OIDC Identity provider as environment variables ACCOUNT ID aws sts get caller identity query Account output text export EKS CLUSTER

on EKS We will need to create and attach policy to role since we only want to allow PutItem and GetItem operations from our application Here is the policy JSON file Version Statement Sid PutandGet

policy policy document file policy jsonaws iam attach role policy role name ROLE NAME policy arn arn aws iam lt enter AWS account ID gt policy dynamodb irsa policyFinally we need to associate the IAM role and Service Account kubectl annotate serviceaccount n default eks dynamodb app sa eks amazonaws com role arn arn aws iam lt enter AWS account ID gt role dynamodb app irsaGet the EKS kubectl role ARNTo reference existing EKS cluster in AWS CDK you need EKS cluster name and kubectl role ARN You can find the role ARN in the Outputs section of the AWS Cloud Formation stack We are ready to deploy the application using CDK Set the required environment variables followed by cdk deploy you can also use cdk synth to generate and inspect the Cloud Formation template firstexport EKS CLUSTER NAME lt enter name of EKS cluster gt export KUBECTL ROLE ARN lt enter kubectl role ARN gt export SERVICE ACCOUNT NAME eks dynamodb app saexport APP PORT export AWS REGION lt enter region e g us east gt cdk deployCDK and cdks will do all the heavy lifting we will look at the code very soon New DynamoDB table will be createdThe docker image for our application will be built and pushed to ECRKubernetes resources for the URL shortener application will be deployed to the existing EKS clusterOnce the stack creation is complete check the Kubernetes Deployment and Service kubectl get deployment dynamodb appkubectl get podskubectl get service dynamodb app serviceTesting the URL shortener service is easy But I will not repeat it here since its already covered in this blog All you need is the load balancer URL to access the service and use yout browser or curl to save and access URLs Back to exploring Go code againWithin the stack we define the DynamoDB table using awsdynamodb NewTable along with the docker image for our application with awsecrassets NewDockerImageAsset func NewDynamoDBAppStack scope constructs Construct id string props CdkStackProps awscdk Stack table awsdynamodb

integration between AWS CDK and cdks and how easy it makes things compared to just using CDK to deploy apps to EKS Then we moved on to explore a full fledged scenario where you deployed the infrastructure DynamoDB etc along with the client application on EKS Happy Building	2022-11-16 06:11:45
