HelmChart

class aws_cdk.aws_eks_v2.HelmChart(scope, id, *, cluster, atomic=None, chart=None, chart_asset=None, create_namespace=None, namespace=None, release=None, removal_policy=None, repository=None, skip_crds=None, timeout=None, values=None, version=None, wait=None)

Bases: Construct

Represents a helm chart within the Kubernetes system.

Applies/deletes the resources using kubectl in sync with the resource.

ExampleMetadata:: infused

Example:

# cluster: eks.Cluster

# option 1: use a construct
eks.HelmChart(self, "MyOCIChart",
    cluster=cluster,
    chart="some-chart",
    repository="oci://${ACCOUNT_ID}.dkr.ecr.${ACCOUNT_REGION}.amazonaws.com/${REPO_NAME}",
    namespace="oci",
    version="0.0.1"
)

Parameters:

scope (Construct)
id (str)
cluster (ICluster) – The EKS cluster to apply this configuration to. [disable-awslint:ref-via-interface]
atomic (Optional[bool]) – Whether or not Helm should treat this operation as atomic; if set, upgrade process rolls back changes made in case of failed upgrade. The –wait flag will be set automatically if –atomic is used. Default: false
chart (Optional[str]) – The name of the chart. Either this or chartAsset must be specified. Default: - No chart name. Implies chartAsset is used.
chart_asset (Optional[Asset]) – The chart in the form of an asset. Either this or chart must be specified. Default: - No chart asset. Implies chart is used.
create_namespace (Optional[bool]) – create namespace if not exist. Default: true
namespace (Optional[str]) – The Kubernetes namespace scope of the requests. Default: default
release (Optional[str]) – The name of the release. Default: - If no release name is given, it will use the last 53 characters of the node’s unique id.
removal_policy (Optional[RemovalPolicy]) – The removal policy applied to the custom resource that manages the Helm chart. 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
repository (Optional[str]) – The repository which contains the chart. For example: https://charts.helm.sh/stable/ Default: - No repository will be used, which means that the chart needs to be an absolute URL.
skip_crds (Optional[bool]) – if set, no CRDs will be installed. Default: - CRDs are installed if not already present
timeout (Optional[Duration]) – Amount of time to wait for any individual Kubernetes operation. Maximum 15 minutes. Default: Duration.minutes(5)
values (Optional[Mapping[str, Any]]) – The values to be used by the chart. For nested values use a nested dictionary. For example: values: { installationCRDs: true, webhook: { port: 9443 } } Default: - No values are provided to the chart.
version (Optional[str]) – The chart version to install. Default: - If this is not specified, the latest version is installed
wait (Optional[bool]) – Whether or not Helm should wait until all Pods, PVCs, Services, and minimum number of Pods of a Deployment, StatefulSet, or ReplicaSet are in a ready state before marking the release as successful. Default: - Helm will not wait before marking release as successful

Methods

to_string()

Returns a string representation of this construct.

Return type:: str

with_(*mixins)

Applies one or more mixins to this construct.

Mixins are applied in order. The list of constructs is captured at the start of the call, so constructs added by a mixin will not be visited. Use multiple with() calls if subsequent mixins should apply to added constructs.

Parameters:: mixins (IMixin) – The mixins to apply.
Return type:: IConstruct
Returns:: This construct for chaining

Attributes

RESOURCE_TYPE = 'Custom::AWSCDK-EKS-HelmChart'

atomic: Whether or not Helm should treat this operation as atomic.

chart: The name of the chart.

chart_asset: The chart in the form of an asset.

node: The tree node.

repository: The repository which contains the chart.

version: The chart version to install.

Static Methods

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.
