Default: true

Indicates whether Kubernetes resources added through addManifest() can be automatically pruned.

When this is enabled (default), prune labels will be allocated and injected to each resource. These labels will then be used when issuing the kubectl apply operation with the --prune switch.

Returns:

  • (Boolean, nil)

#remote_node_networksArray<AWSCDK::EKS::RemoteNodeNetwork>? (readonly)

Note:

Default: - none

IPv4 CIDR blocks defining the expected address range of hybrid nodes that will join the cluster.

Returns:

# File 'eks/cluster_options.rb', line 297

def remote_node_networks
  @remote_node_networks
end

#remote_pod_networksArray<AWSCDK::EKS::RemotePodNetwork>? (readonly)

Note:

Default: - none

IPv4 CIDR blocks for Pods running Kubernetes webhooks on hybrid nodes.

Returns:

end

#removal_policyAWSCDK::RemovalPolicy? (readonly)

Note:

Default: - Resources will be deleted.

The removal policy applied to all CloudFormation resources created by this construct when they are no longer managed by CloudFormation.

This can happen in one of three situations:

  • The resource is removed from the template, so CloudFormation stops managing it;
  • A change to the resource is made that requires it to be replaced, so CloudFormation stops managing it;
  • The stack is deleted, so CloudFormation stops managing all resources in it.

This affects the EKS cluster itself, associated IAM roles, node groups, security groups, VPC and any other CloudFormation resources managed by this construct.

Returns:

# File 'eks/cluster_options.rb', line 316

def removal_policy
  @removal_policy
end

#roleAWSCDK::IAM::IRole? (readonly)

Note:

Default: - A role is automatically created for you

Role that provides permissions for the Kubernetes control plane to make calls to AWS API operations on your behalf.

Returns:

# File 'eks/cluster_options.rb', line 132

def role
  @role
end

#secrets_encryption_keyAWSCDK::Interfaces::AWSKMS::IKeyRef? (readonly)

Note:

Default: - By default, Kubernetes stores all secret object data within etcd and all etcd volumes used by Amazon EKS are encrypted at the disk-level using AWS-Managed encryption keys.

KMS secret for envelope encryption for Kubernetes secrets.

def secrets_encryption_key
  @secrets_encryption_key
end

#security_groupAWSCDK::EC2::ISecurityGroup? (readonly)

Note:

Default: - A security group is automatically created

Security Group to use for Control Plane ENIs.

Returns:

139
# File 'eks/cluster_options.rb', line 137

def security_group
  @security_group
end

#service_ipv4_cidrString? (readonly)

Note:

Default: - Kubernetes assigns addresses from either the 10.100.0.0/16 or 172.20.0.0/16 CIDR blocks

The CIDR block to assign Kubernetes service IP addresses from.

328
329
# File 'eks/cluster_options.rb', line 327

def service_ipv4_cidr
  @service_ipv4_cidr
end

#vpc_subnetsArray<AWSCDK::EC2::SubnetSelection>? (readonly)

Note:

Default: - All public and private subnets

Where to place EKS Control Plane ENIs.

For example, to only select private subnets, supply the following:

vpcSubnets: [{ subnetType: ec2.SubnetType.PRIVATE_WITH_EGRESS }]

Returns:
