📝 WalkthroughWalkthroughThe PR replaces EKS Auto Mode compute with self-managed Karpenter, adds AWS Load Balancer Controller integration, updates private-cluster bootstrap behavior, and adjusts Argo CD synchronization, monitoring, validation, documentation, and operational timeouts. ChangesKarpenter platform migration
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The PR is mergeable with explicit owner awareness: documentation in terraform/modules/ecs-bootstrap/README.md inaccurately describes cluster ownership, bootstrap ordering, and security/audit scope, which could mislead operators.

Replaces AWS EKS Auto Mode with self-managed Karpenter for more granular control over node provisioning and scaling across Regional and Management Clusters. Key changes: - Remove Auto Mode enablement from EKS module - Deploy Karpenter controller via Helm with GitOps - Configure EC2NodeClass and NodePool resources, pinned to bottlerocket v1.64.0 instead of the floating @latest alias - Add AWS Load Balancer Controller for RC (Karpenter dependency), using the current elbv2.k8s.aws/v1beta1 TargetGroupBinding API, pinned to the same AWS provider version (~> 6.56.0) as the rest of the repo - Upgrade bootstrap node group from t3.medium to t3.large for ArgoCD HA - Applications sync concurrently with no sync-wave ordering, consistent with the project's eventual-consistency ArgoCD model (selfHeal + retry.limit=-1 with backoff). Cross-Application CRD races (eks-nodepool/karpenter, ServiceMonitor+PrometheusRule/monitoring, TargetGroupBinding/aws-load-balancer-controller) are handled via per-resource argocd.argoproj.io/sync-options annotations, matching the existing cert-manager ClusterIssuer pattern, rather than a global SkipDryRunOnMissingResource flag that would mask real bugs everywhere - Remove CriticalAddonsOnly tolerations from the monitoring stack (prometheusOperator, kube-state-metrics, prometheus) — monitoring has no chicken-and-egg bootstrap dependency like ArgoCD/Karpenter do, so it can wait for Karpenter to provision a regular workload node instead of competing for fixed bootstrap-node capacity - Update Helm download with retry logic and SHA-256 checksum verification - Improve HyperShift install error handling (capture output, check stderr) - Restore hyperfleet values.yaml to upstream defaults - Remove stale hyperfleetApi/Sentinel/Adapter valuesObject keys left over from the pre-consolidation chart layout - Restore a response_templates block on the API Gateway default_4xx response that was silently dropped in this branch's rebase history, reverting a real upstream Terraform state-drift fix - Restore force_destroy variable on the regional-oidc module and revert an incorrect platform-monitoring test workaround, both reverted to match upstream/main Hardening added during review: - Gate the post-bootstrap HyperShift Synced+Healthy wait behind an explicit WAIT_FOR_HYPERSHIFT_HEALTH flag so ordinary bootstraps (not just the E2E workflow) skip it, and add --request-timeout to every kubectl call in that loop so a hung connection can't block past the loop's own deadline - Require a non-empty karpenter_controller_role_arn via variable validation instead of allowing a silent empty default - Build the ECS RunTask --overrides payload with jq -n --arg for every value instead of interpolating shell variables into hand-built JSON, removed a duplicated CLUSTER_TYPE entry, and fail clearly before the RunTask call if the serialized payload nears ECS's 8192-character limit - Correct documentation that had fallen out of sync with the implementation: sync-wave ordering claims, IAM role inventory, FIPS/ FedRAMP compliance scope, and stale version references Terminology: "OSS Karpenter" renamed to "self-managed Karpenter" throughout docs, comments, and Terraform descriptions — EKS Auto Mode also runs Karpenter internally, so "OSS" didn't capture the actual distinction; "self-managed" states it directly (ArgoCD-managed lifecycle vs AWS-managed under Auto Mode). Known gaps: - karpenter's own chart-managed ServiceMonitor (from the upstream oci://public.ecr.aws/karpenter chart) has no annotations passthrough for SkipDryRunOnMissingResource, so it still relies on retry/selfHeal alone to recover from a missing monitoring CRD on first bootstrap. - Disabling Prometheus Operator's admissionWebhooks (needed to avoid a PreSync hook Job race during ArgoCD's own bootstrap self-sync — a ttlSecondsAfterFinished-based workaround was tried first and found insufficient) also disables admission-time promql validation for PrometheusRule; malformed rules are applied instead of rejected. - WAIT_FOR_HYPERSHIFT_HEALTH is defined and validated but nothing in this repo sets it to "true" yet — the external CI job definition that chains provisioning immediately into E2E tests needs to export it. Infrastructure validation: - Tested in ephemeral environment with full RC + MC provisioning - Verified node provisioning metrics in CloudWatch - Confirmed Karpenter scales nodes based on pending pods Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…gional-cluster/ argocd/config/management-cluster/karpenter and .../regional-cluster/karpenter were symlinks to shared/karpenter with no consumer: find (used by make helm-lint) doesn't follow symlinked directories by default, so they were never actually linted via these paths, and no script or template references them. The ApplicationSet already discovers shared/karpenter directly for both cluster types. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…ing gap ArgoCD HA (server, application-controller, repo-server, applicationset, dex, notifications, plus a redis-ha subchart with 3 redis + 3 haproxy pods carrying zero resource requests anywhere in the dependency chain) and the Karpenter controller run on a fixed 2-node group. Explicit resource requests alone already total ~1.75 vCPU / ~3.2 GiB across the two nodes, against ~1.9 vCPU / ~7 GiB allocatable per t3.large (2 vCPU / 8 GiB raw) node, before counting the zero-request redis-ha/haproxy pods or system DaemonSets. Bump to m7i.xlarge (4 vCPU / 16 GiB) for real headroom, and sync every doc/comment reference to the old instance type. Also add the CriticalAddonsOnly toleration to the AWS Load Balancer Controller, which had none — a verified, independent bug that left it unable to schedule until Karpenter provisions untainted nodes. Investigated and explicitly declined a proposal to replace CriticalAddonsOnly tolerations with a PriorityClass on ArgoCD/Karpenter instead: the "toleration sprawl" premise doesn't hold (prometheusOperator, kube-state-metrics, and prometheus carry no such toleration today), and the claim that this would let us drop the monitoring admissionWebhooks/tls workaround doesn't hold either — that workaround exists because ArgoCD's own controller restarts during its own GitOps self-adoption, a reconciliation-timing race that PriorityClass-based preemption has no mechanism to prevent.

…ctl path The destroy provisioner tried to reach the cluster API (update-kubeconfig, kubectl delete nodepools) before falling back to tag-based EC2 termination. The CodeBuild project that runs terraform destroy has no VPC connectivity to this fully-private cluster's API, so that path never actually succeeds in practice -- it silently fell through the 2>/dev/null fallback to the same tag-based termination every time, masking a real reachability gap behind what looked like an intentional "cluster already deleted" skip. Since the whole cluster is being destroyed there's no workload to protect by draining gracefully first, so remove the kubectl-dependent phase entirely rather than building a VPC-connected execution path for a step that provides no benefit. Terminating by tag has no dependency on kubeconfig, cluster reachability, or kubectl being installed. Also wrap the instance-terminated wait in an explicit 300s timeout instead of relying on the AWS CLI waiter's implicit one, and document that LBC only reconciles TargetGroupBinding in this architecture (confirmed no Ingress or LBC-provisioned ALB/NLB usage anywhere in argocd/config/), so there's no orphaned load balancer to worry about here. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Adds CriticalAddonsOnly tolerations required for self-managed Karpenter bootstrap architecture: - Job pod tolerations: allows hypershift-install Job to schedule on karpenter-bootstrap node group (m7i.xlarge, CriticalAddonsOnly taint) - external-dns deployment toleration patch: ensures external-dns (created by hypershift install CLI) can schedule on bootstrap nodes Also removes direct Karpenter version references from documentation: - docs/design/fips-eks-compute.md: remove "v1" - docs/design/karpenter-node-provisioning.md: remove "v1 (1.14.0)" - docs/sop/karpenter-lifecycle.md: use placeholder version in example Without these tolerations, both the hypershift-install Job and external-dns pods would be stuck in Pending state during cluster bootstrap, as Karpenter has not yet provisioned any workload nodes. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
…nodes to Bottlerocket Switches the karpenter-bootstrap node group from AL2023 to Bottlerocket (matching the AMI family Karpenter-provisioned workload nodes already use) and replaces the CriticalAddonsOnly:NoSchedule exclusion taint with a new bootstrap-critical PriorityClass (value 100000, applied to both ArgoCD and Karpenter, deliberately downgrading Karpenter from its chart's default system-cluster-critical). Preemption lets ArgoCD/Karpenter reclaim capacity if the fixed-size node group fills up, instead of excluding every other pod via a taint. All 6 CriticalAddonsOnly toleration sites in the repo are updated accordingly: ArgoCD and Karpenter move to priorityClassName; AWS Load Balancer Controller, the hypershift-install Job, and the Secrets Store CSI Driver DaemonSet just drop the now-unnecessary toleration outright. This is an experimental test branch off remove-auto-mode-v2, not intended to merge directly. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

In `@argocd/config/management-cluster/hypershift/templates/05-job.yaml`:
- Around line 124-145: Fix the shell control flow in the job template: add the
missing fi for the conditional beginning near the earlier setup logic, and
retain only the intended hypershift install invocation after the CRD wait rather
than duplicating the commands. Replace the non-portable SECONDS timer with
POSIX-compatible elapsed-time tracking, while preserving the existing install
exit-code capture and output behavior.
Apply the same fix in
`@argocd/config/management-cluster/hypershift/templates/05-job.yaml` around lines
106 - 121.
In `@argocd/config/management-cluster/monitoring/values.yaml`:
- Around line 20-33: Add a pre-sync validation gate for all management-cluster
monitoring resources applied by hypershift install or ArgoCD before retaining
the disabled Prometheus Operator webhook setting. Extend validation beyond
regional PrometheusRule objects to cover PrometheusRule, Probe, and
AlertmanagerConfig resources, including PromQL and semantic checks; do not rely
on helm lint alone.
In `@docs/design/fips-eks-compute.md`:
- Around line 7-11: Define one enforceable placement contract for
karpenter-bootstrap: update docs/design/fips-eks-compute.md lines 7-11,
docs/sop/karpenter-lifecycle.md lines 44-48, and
terraform/modules/eks-cluster/README.md line 140 consistently, and align the
cluster configuration so the stated placement is enforced through taints and pod
tolerations or through explicit node selectors/affinity; do not treat
bootstrap-critical priority as node-group selection.
In `@scripts/verify-fips.sh`:
- Around line 130-139: Add an explicit kubectl existence check for the
ec2nodeclass named fips in the verification flow, using the same failure
handling as the existing NodePool validation so a missing fips object fails
rather than passes. Preserve the current skip behavior when the Karpenter CRD is
unavailable and anchor the change near the crd_check/crd_status handling.
In `@terraform/config/regional-cluster/imports.sh`:
- Around line 23-25: Update the RHOBS API Gateway log-group import in
import_if_needed to derive the stage name using the existing tf_state_value
approach already used below, rather than relying on TF_VAR_stage_name with a
prod fallback. Confirm and use the stage resource address exposed by the
rhobs-api-gateway module, while preserving the existing log-group path format.
In `@terraform/config/regional-cluster/main.tf`:
- Around line 579-584: Restore the force_destroy input in the regional_oidc
module invocation, wiring it to the appropriate existing variable so the
module’s S3 bucket deletion behavior remains configurable and defaults to false.
In `@terraform/modules/ecs-bootstrap/README.md`:
- Line 77: Update the karpenter_controller_role_arn input and bootstrap
installation flow so an always-installed Karpenter controller cannot proceed
with an empty IRSA role; require and validate the ARN before installation, or
conditionally skip Karpenter when it is absent.
In `@terraform/modules/eks-cluster/iam.tf`:
- Around line 311-324: Update the karpenter_interruption aws_sqs_queue_policy to
restrict EventBridge message delivery with aws:SourceAccount using
data.aws_caller_identity.current.account_id and aws:SourceArn limited to the
intended EventBridge rule ARN, preserving the existing principal, action, and
queue resource.
In `@terraform/modules/eks-cluster/main.tf`:
- Around line 286-291: Update the aws_eks_addon.ebs_csi depends_on list to
include aws_eks_addon.pod_identity alongside the existing dependencies, ensuring
the Pod Identity agent addon is available before the EBS CSI addon is created.
- Around line 139-176: Add a command-availability guard for timeout alongside
the existing aws CLI validation in the local-exec destroy provisioner, emitting
an error and exiting nonzero when it is unavailable. Keep the current
termination and wait logic unchanged.
In `@terraform/modules/eks-cluster/variables.tf`:
- Around line 78-82: Update the ami_kms_key_arn variable description to
accurately reflect the implemented IAM policy: kms:CreateGrant and
kms:DescribeKey granted only to the Karpenter controller role, with no node-role
policy. Preserve the existing behavior that an empty value skips KMS policy
creation.
Apply the same fix in `@terraform/modules/eks-cluster/README.md` at line 142: The
README contains the corresponding conflicting KMS permission description.
In `@terraform/modules/rhobs-api-gateway/README.md`:

Fix the bootstrap script control flow before merging. The rendered /bin/sh script has an unmatched if, causing sh -n to fail with unexpected end of file. It also invokes hypershift install both before and after the CRD wait. Close every conditional, wait for the CRD before the single install invocation, limit the role condition to the external-dns patch, and replace non-POSIX SECONDS with a portable timer.

Add a management-cluster monitoring validation gate before disabling the webhook.
The current promtool-test gate covers only regional PrometheusRule resources. helm lint does not replace PromQL or semantic validation. If the webhook remains disabled, validate every monitoring resource that hypershift install or ArgoCD can apply before sync. Otherwise, malformed rules can reach runtime and create alerting gaps.

Define and enforce one bootstrap node-placement contract. bootstrap-critical controls priority and preemption. It does not select the karpenter-bootstrap node group. The node group has no taint, and ArgoCD and Karpenter define no node selector or affinity, so other pods can schedule there and these pods are not guaranteed to remain there. Either add the required taints and pod tolerations or revise the placement claims in all three documents.

Derive the RHOBS stage name from Terraform state.
TF_VAR_stage_name is never exported by scripts/buildspec/provision-infra-rc.sh, so this expression always resolves to prod. If the RHOBS API Gateway stage uses a different name, the import misses the existing log group and import_if_needed reports [not-found]. Terraform then attempts to create a log group that already exists, and the apply fails with ResourceAlreadyExistsException.
The block below at Lines 29-31 already reads the stage name from state with tf_state_value. Use the same approach here.
As per path instructions for terraform/config/**: "Review for consistency with the corresponding module interfaces. Ensure backend configuration is correct and variables match module expectations."

Scope the SQS queue policy to this account and these rules.
The queue policy allows events.amazonaws.com to call sqs:SendMessage without a source condition. Any EventBridge rule in any AWS account can then publish to this queue. Karpenter treats queue messages as interruption events and drains or terminates the matching nodes, so injected messages cause unnecessary node churn.
Add aws:SourceAccount and aws:SourceArn conditions. The upstream Karpenter CloudFormation template uses the same pattern.
As per path instructions: "Review for AWS security best practices and least-privilege IAM policies."

Align the KMS permission documentation with the implemented policy.

Restore spec dump-env wording and remove karpenter-lifecycle SOP that does not exist in upstream/main. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
… README accuracy - Add aws_eks_addon.pod_identity to ebs_csi depends_on so the Pod Identity agent is installed before the EBS CSI driver - Update TargetGroupBinding apiVersion from v1alpha1 to v1beta1 - Add timeout command-availability guard in destroy provisioner - Fix ecs-bootstrap README to mark karpenter_controller_role_arn as required (matches variables.tf validation) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The bootstrap addon wait loop only checked coredns and metrics-server. After migrating to self-managed Karpenter, the LBC authenticates via Pod Identity -- if the agent DaemonSet isn't running when ArgoCD deploys the LBC, it can't assume its IAM role, TargetGroupBindings are never reconciled, and the Platform API ALB returns 503 indefinitely. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…rap nodes redis-ha defaults to 3 replicas with hardAntiAffinity requiring each on a separate node. The karpenter-bootstrap node group has only 2 nodes, so the 3rd replica can never schedule and helm install --wait times out. Set replicas to 2 and hardAntiAffinity to false on both redis-ha and haproxy. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…nter clusters The AWS Load Balancer Controller defaults to discovering VPC ID from EC2 instance metadata (IMDS), which fails on the karpenter-bootstrap node group with "context deadline exceeded". Without a running LBC, TargetGroupBindings are never reconciled, the Platform API ALB target group stays empty, and /live returns 503 indefinitely. Thread the VPC ID through the existing annotation pipeline (Terraform vpc_id variable -> ECS VPC_ID env var -> cluster secret vpc_id annotation -> ApplicationSet valuesObject -> LBC Helm vpcId) so the controller skips the IMDS lookup entirely.

…nodes to Bottlerocket Switches the karpenter-bootstrap node group from AL2023 to Bottlerocket (matching the AMI family Karpenter-provisioned workload nodes already use) and replaces the CriticalAddonsOnly:NoSchedule exclusion taint with a new bootstrap-critical PriorityClass (value 100000, applied to both ArgoCD and Karpenter, deliberately downgrading Karpenter from its chart's default system-cluster-critical). Preemption lets ArgoCD/Karpenter reclaim capacity if the fixed-size node group fills up, instead of excluding every other pod via a taint. All 6 CriticalAddonsOnly toleration sites in the repo are updated accordingly: ArgoCD and Karpenter move to priorityClassName; AWS Load Balancer Controller, the hypershift-install Job, and the Secrets Store CSI Driver DaemonSet just drop the now-unnecessary toleration outright. This is an experimental test branch off remove-auto-mode-v2, not intended to merge directly. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

- Around line 42-46: Update the post-bootstrap wording near the Karpenter and
eks-nodepool steps so CLM remains the authoritative source of truth for cluster
state; describe ArgoCD only as reconciling applications and add-ons, without
implying it takes over cluster management.

the inaccurate “sync wave 0/10” claims and avoid asserting addon placement on
karpenter-bootstrap or readiness of Karpenter and eks-nodepool. Describe the
actual retry-based/concurrent Application synchronization behavior, unless the
implementation adds and documents explicit readiness gates or E2E assertions for
those components.
- Around line 58-65: Revise the “Minimal Permissions” and “Audit Trail” claims
to accurately reflect the module: acknowledge the granted unused addon,
nodegroup, SSM, Secrets Manager, and cluster-admin permissions, and describe
CloudWatch as capturing container streams rather than complete bootstrap
operations or Karpenter prewarm diagnostics. Do not claim permissions are
limited to required actions or that all command errors are captured.

Correct the documented bootstrap ordering.
The task waits for EKS add-ons to become Active, but it does not verify placement on karpenter-bootstrap. Child Applications have no sync waves and sync concurrently. The task also does not wait for Karpenter or eks-nodepool health. Remove the sync wave 0/10 claims and document retry-based ordering, or add a readiness gate or E2E assertion for Karpenter and eks-nodepool.

Keep CLM as the source of truth for cluster state.
The sentence “ArgoCD takes over cluster management” assigns cluster-state ownership to ArgoCD. The repository rule requires CLM to remain the single source of truth. Limit this wording to ArgoCD reconciliation of applications and add-ons, while keeping CLM authoritative.
Proposed wording
-After ECS bootstrap completes, ArgoCD takes over cluster management:
+After ECS bootstrap completes, ArgoCD reconciles the configured applications and add-ons while CLM remains the source of truth for cluster state:As per coding guidelines: “Maintain CLM as the single source of truth for cluster state.”

AWS CLI eks update-kubeconfig API calls and eks wait addon-active API calls required IAM actions
💡 Result:
The required IAM actions for the specified AWS CLI commands are as follows: aws eks update-kubeconfig To use the update-kubeconfig command, an IAM principal must have permission to perform the eks:DescribeCluster action for the specified EKS cluster [1][2][3]. If you are listing or describing all clusters in an account, the actions eks:ListClusters and eks:DescribeCluster are required [1]. aws eks wait addon-active The wait addon-active command works by polling the eks:DescribeAddon API action until the add-on status reaches ACTIVE [4][5]. Consequently, an IAM principal requires permission to perform the eks:DescribeAddon action to use this waiter successfully [4][5]. For scenarios involving cross-account access or role assumption (such as using the --role-arn option in update-kubeconfig), the IAM principal also requires the sts:AssumeRole permission for the target role [6]. Furthermore, note that while these IAM actions allow the CLI to fetch configuration or status, actual interaction with the Kubernetes cluster (e.g., using kubectl) is handled separately through EKS authentication mechanisms (such as AWS IAM Access Entries or the aws-auth ConfigMap), which may require additional permissions or configuration [7][3][8].

AWS IAM EKS API actions resource-level permissions ListClusters ListNodegroups DescribeNodegroup DescribeUpdate CreateAddon UpdateAddon
💡 Result:
In AWS Identity and Access Management (IAM), resource-level permissions allow you to specify which resources (such as specific clusters or nodegroups) a policy statement applies to [1]. Whether an EKS action supports resource-level permissions depends on the specific API operation [1]. Below is the resource-level permission support for the requested EKS actions based on official AWS documentation [2][3]: Action | Resource-Level Permissions Support | Required Resource Type --- | --- | --- CreateAddon | Yes | cluster [2][3] UpdateAddon | Yes | addon [3] DescribeNodegroup | Yes | nodegroup [3] DescribeUpdate | Yes | addon (or cluster/nodegroup) [3] ListNodegroups | Yes | cluster [2][3] ListClusters | No | * (All resources) [2][3] Summary of Findings: 1. Actions with Resource-Level Support: For actions that support resource-level permissions (e.g., CreateAddon, UpdateAddon, DescribeNodegroup, DescribeUpdate, and ListNodegroups), you can specify an Amazon Resource Name (ARN) in your IAM policy to restrict access to specific EKS resources [1]. These actions often support condition keys such as aws:ResourceTag/${TagKey} [2][3]. 2. Actions without Resource-Level Support: The ListClusters action does not support resource-level permissions [2][3]. In IAM policies, this action must be applied to all resources using a wildcard () [1][4]. 3. Implementation Note: If you are using the AWS Management Console and encounter a warning stating that an action does not support resource-level permissions, it indicates that the action must be applied to "All resources" () in your policy statement [4]. This is standard for listing and certain metadata-retrieval operations in EKS [1].

Narrow the security and audit claims. The task uses only eks:DescribeCluster and eks:DescribeAddon from the listed EKS APIs, but the role also grants unused addon, nodegroup, SSM, and Secrets Manager actions. ListClusters is scoped to a cluster ARN although it requires Resource = "*". The role also receives cluster-wide AmazonEKSClusterAdminPolicy. CloudWatch captures the container streams, but the module has no Karpenter prewarm diagnostics path and suppresses some command errors.
