I can't seem to figure out a way to append

clusterTags

to existing EKS cluster, does someone have a hint?

What provider (and version of it) are you using? If you're using

pulumi-eks

, the tags you set in

clusterTags

should get applied to the underlying EKS cluster resource no matter if you're creating a new cluster or updating an existing one

Follow-up question: what if we're using the

pulumi_aws

package already instead?

It also has a tags property: https://www.pulumi.com/registry/packages/aws/api-docs/eks/cluster/#tags_python

Sorry, I should have made myself more clear 🙂 Due to our customer, we are forced to work with an existing

pulumi_aws.eks.Cluster

, which we obtained in our Pulumi script using the .get(...) method. We want to add a tag to the EKS cluster for our Karpenter deployment. I've already found out that we have

cluster.tags

, but changing this using

cluster.tags.apply(lambda tags: tags.update({"testMe": "testMe"}))

only changes the Pulumi state & not the tags on the actual cluster.

I'm not aware of any

Tag

resource for EKS 😞 One option that I can think of is using the command provider to execute an aws cli script. Resources retrieved with

.get

will never be updated/deleted during an update. It's just used for fetching the resource's attributes

That's (almost 😉 ) the way we solved it, but we were curious if there was a better approach. Thanks for the help!

You could also create a dynamic resource provider for this. How did you end up solving it? 🙂

I didn't quite understand how the

Command

class could be used to manage the lifecycle of a tag object, so indeed I ended up using a dynamic resource & resource provider that just calls the AWS CLI to create, get (with some jq parsing) & delete the resource 🙂
