Cluster

Source: src/AWS/EKS/Cluster.ts

An Amazon EKS cluster with support for EKS Auto Mode settings.

Creating Clusters

Auto Mode Cluster (managed roles)

const cluster = yield* Cluster("AppCluster", {
  compute: "auto",
  resourcesVpcConfig: {
    subnetIds: network.privateSubnetIds,
  },
});

Auto Mode Cluster from Existing Roles and Subnets

const cluster = yield* Cluster("AppCluster", {
  roleArn: clusterRole.roleArn,
  resourcesVpcConfig: {
    subnetIds: network.privateSubnetIds,
    endpointPublicAccess: true,
    endpointPrivateAccess: true,
  },
  accessConfig: {
    authenticationMode: "API",
  },
  computeConfig: {
    enabled: true,
    nodeRoleArn: nodeRole.roleArn,
    nodePools: ["system", "general-purpose"],
  },
  kubernetesNetworkConfig: {
    elasticLoadBalancing: { enabled: true },
  },
  storageConfig: {
    blockStorage: { enabled: true },
  },
});

Running Workloads

const cluster = yield* AWS.EKS.Cluster("AppCluster", {
  roleArn: clusterRole.roleArn,
  resourcesVpcConfig: { subnetIds: network.privateSubnetIds },
  accessConfig: { authenticationMode: "API" },
});

const nodes = yield* AWS.EKS.Nodegroup("AppNodes", {
  clusterName: cluster.clusterName,
  nodeRole: nodeRole.roleArn,
  subnets: network.privateSubnetIds,
  instanceTypes: ["t3.medium"],
  scalingConfig: { minSize: 1, maxSize: 2, desiredSize: 1 },
});

const metricsServer = yield* AWS.EKS.Addon("MetricsServer", {
  clusterName: cluster.clusterName,
  addonName: "metrics-server",
});
