KubernetesObjectValueProps

class aws_cdk.aws_eks_v2_alpha.KubernetesObjectValueProps(*, cluster, json_path, object_name, object_type, object_namespace=None, removal_policy=None, timeout=None)

Bases: object

(experimental) Properties for KubernetesObjectValue.

Parameters:

cluster (ICluster) – (experimental) The EKS cluster to fetch attributes from. [disable-awslint:ref-via-interface]
json_path (str) – (experimental) JSONPath to the specific value.
object_name (str) – (experimental) The name of the object to query.
object_type (str) – (experimental) The object type to query. (e.g ‘service’, ‘pod’…)
object_namespace (Optional[str]) – (experimental) The namespace the object belongs to. Default: ‘default’
removal_policy (Optional[RemovalPolicy]) – (experimental) The removal policy applied to the custom resource that manages the Kubernetes object value. The removal policy controls what happens to the resource if it stops being 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 Default: RemovalPolicy.DESTROY
timeout (Optional[Duration]) – (experimental) Timeout for waiting on a value. Default: Duration.minutes(5)

Example:

# cluster: eks.Cluster

# query the load balancer address
my_service_address = eks.KubernetesObjectValue(self, "LoadBalancerAttribute",
    cluster=cluster,
    object_type="service",
    object_name="my-service",
    json_path=".status.loadBalancer.ingress[0].hostname"
)

# pass the address to a lambda function
proxy_function = lambda_.Function(self, "ProxyFunction",
    handler="index.handler",
    code=lambda_.Code.from_inline("my-code"),
    runtime=lambda_.Runtime.NODEJS_LATEST,
    environment={
        "my_service_address": my_service_address.value
    }
)

Attributes

cluster

(experimental) The EKS cluster to fetch attributes from.

[disable-awslint:ref-via-interface]

Stability:: experimental

json_path

(experimental) JSONPath to the specific value.

See:: https://kubernetes.io/docs/reference/kubectl/jsonpath/
Stability:: experimental

object_name

(experimental) The name of the object to query.

Stability:: experimental

object_namespace

(experimental) The namespace the object belongs to.

Default:: ‘default’
Stability:: experimental

object_type

(experimental) The object type to query.

(e.g ‘service’, ‘pod’…)

Stability:: experimental

removal_policy

(experimental) The removal policy applied to the custom resource that manages the Kubernetes object value.

The removal policy controls what happens to the resource if it stops being 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

Default:: RemovalPolicy.DESTROY
Stability:: experimental

timeout

(experimental) Timeout for waiting on a value.

Default:: Duration.minutes(5)
