I am not 100% clear about your use case. Are you able to share a minimal code to illustrate your use case? Generally when you define a HelmChart, under the hood the custom resource would always run helm upgrade for you.

@pahud we are deploying some charts using the following CDK
const openmetadataHelmChart = new eks.HelmChart( this, addStageSuffix('ABCOpenmetadataHelmChart', props.stage), { cluster: props.eksCluster, chart: 'openmetadata', repository: 'oci://' + props.ecrOpenMetadataRepo.repositoryUri, release: 'openmetadata', namespace: 'default', version: '1.1.14', values: openmetadataDefinition, timeout: Duration.minutes(15), }, );
The values openmetadataDefinition
is a yaml which we parse before applying to it:
const openmetadataDefinition = yaml.parse( fs.readFileSync(path.join(__dirname, '../../../lib/resources/yaml/openmetadata.yaml'), 'utf8'), );
However, any change to yaml isn't reflected in the pods run. To make a change, we've to bring down the stack by deleting it. Recreating the stack as new one helps in picking up the new changes to the yaml file
if the resource is already running an helm upgrade, what probably can help us fix the above behavior. We don't want to everytime bring the stack down just for upgrading config values
I guess the proposed solution is as straightforward as https://github.com/aws/aws-cdk/issues/22254, just need to add the --reuse-values
flag for helm commands.
Describe the feature
support upgrade or install helm chart as an argument to eks.HelmChart
Use Case
We've a EKS cluster and use CDK to run helm charts and pass values by reading in a yaml and parsing it. However, in some use cases, where we make an update to the yaml values file, the changes do not take into effect when we update the stack. As a workaround, we currently delete the stack and recreate it with new values.
Proposed Solution
to have an argument to let either upgrade or install the helm charts https://helm.sh/docs/helm/helm_upgrade/
