[BUG] Fargate only cluster creates "default" fargate profile without asking/configuring it

[tsahiduek]

Trying to create a Fargate only cluster with single fargate profile, results in 2 fargate profiles that are being created: the configured one, and another one called default targeting kube-system and default namespaces

Configurations snippet

        const fargateProfiles: Map<string, eks.FargateProfileOptions> = new Map([
            ["base-profile", { selectors: [{ namespace: "kube-system" }, { namespace: "karpenter" }] }],

        ]);
        const fargateClusterProvider = new ssp.FargateClusterProvider({
            fargateProfiles,
            version: clusterVersion
        });

        const blueprint = ssp.EksBlueprint.builder()
            .account(PIPELINE_ENV.account)
            .region(PIPELINE_ENV.region)
            .withBlueprintProps({
                version: clusterVersion,
            })
            .clusterProvider(fargateClusterProvider)

Same happened to me..

This works as designed. The behavior is similar to ekscstl --fargate behavior. See more here.

You can leverage the generic cluster provider to configure arbitrary fargate profiles (no default). Please let me know if you have any questions. I will keep the issue to make sure the docs reflect it properly.

I was facing the same today. I don't want a default Fargate profile (Only one for the Karpenter namespace). Using the generic Cluster Provider it's easy to solve this:

    const clusterProvider = new blueprints.GenericClusterProvider({
      version: eks.KubernetesVersion.V1_21,
      fargateProfiles: {
        karpenter: {
          fargateProfileName: 'karpenter',
          selectors: [{ namespace: 'karpenter' }],
        },
      },
    });

However, we might want to explicitly call out the 'default' behaviour in the documentation when leveraging. FargateClusterProvider
