fix(eks): apply eks.amazonaws.com/nodegroup label via k3s node-label drop-in (#534)
The nodegroup label was only written to K3S_NODE_LABEL in agent.env, but k3s has no such env var, so non-GPU workers never received the label. waitWorkersReady buckets Ready nodes by that label (added in #511), so the affected nodegroups never counted toward their ACTIVE transition and stayed CREATING until timeout. Ride the label on a real k3s node-label config drop-in (15-nodegroup-label.yaml), delivered via cloud-init user-data. Drop the inert K3S_NODE_LABEL from agent.env and the initd export. |

feat(eks): aws-load-balancer-controller addon — real ALB Ingress (L7, IRSA) (#376)
* fix(ec2): stamp subnet AvailabilityZoneId for single-AZ ALB resolution
DescribeSubnets omitted AvailabilityZoneId, so the AWS Load Balancer
Controller's DescribeAvailabilityZones-by-ZoneId lookup resolved no AZ
info ("cannot resolve AZ info for AZs: []") and never built the ALB
model. Stamp the single zone-id on every subnet and share it with
DescribeAvailabilityZones through one SingleZoneID constant so the two
responses can never drift.
* feat(eks): add aws-load-balancer-controller v2.8.1 addon bundle
Baked manifests for the LBC managed addon (CRDs, controller Deployment/
RBAC/webhooks/Service, IngressClass alb, IRSA render markers). Two
wirings make it work against the spinifex gateway:
- --aws-api-endpoints carries sts= alongside elasticloadbalancing/ec2/
acm. The aws-sdk-go v1 credential bootstrap resolves the STS client
from the session endpoint resolver, not AWS_ENDPOINT_URL_STS, so the
web-identity AssumeRoleWithWebIdentity must be pointed at the gateway
here or it falls back to real AWS STS.
- --feature-gates=ALBSingleSubnet=true drops the ALB minimum subnet
count from two to one so an ALB provisions in a single-AZ deployment.
* feat(eks): render IRSA into managed addons + node-minted webhook cert
Extend the addon-sync renderer to inject the projected-token / role-arn /
gateway STS-endpoint + CA block into managed-addon pod specs via opt-in
markers, and substitute cluster-name/region/vpc-id/gateway-endpoint/CA
placeholders. Add cmd/eks-webhook-cert: the eks-node AMI has no openssl,
so this mints (then reuses) a self-signed ECDSA-P256 serving cert for the
admission webhook, cached on disk so the render is byte-stable across
ticks. Wire both into the image build (manifest.conf) plus INSTALL_FILES
for the LBC bundle.
* feat(eks): surface cluster VPC id as EKS_VPC_ID for the LB controller
Thread the control-plane VPC id through K3sServerInput.VpcID into the
first-boot EKS_VPC_ID env so the in-cluster aws-load-balancer-controller
can pass --aws-vpc-id to the gateway elbv2/ec2 handlers.
* fix(eks): point the LB controller at the customer VPC + customer-facing gateway
The aws-load-balancer-controller ran with two control-plane-scoped values
that customer worker pods cannot use:
- --aws-vpc-id was set from the managed control-plane VPC (cpRefs.VpcID),
which the gateway's DescribeVpcs does not return for customer calls, so
backend-SG auto-create failed with InvalidVpcID.NotFound. Source it from
meta.ResourcesVpcConfig.VpcId, the customer cluster VPC where the workers
and their subnets live and where the ALB is provisioned.
- The addon render baked the mgmt gateway endpoint (EKS_GATEWAY_URL /
SystemGatewayURL) into pod specs, unreachable from worker pods. Add a
distinct EKS_ADDON_GATEWAY_URL (the customer-facing GatewayBaseURL, same
host as the OIDC issuer) and substitute it for {{GATEWAY_ENDPOINT}} in
managed addon manifests. EKS_GATEWAY_URL stays mgmt for the CP's own
bootstrap, state-report and token-webhook paths.
* fix(elbv2): resolve forward target group from ForwardConfig
listenerActionFromSDK read only the legacy flat Action.TargetGroupArn, so a
forward action carrying its target group via ForwardConfig.TargetGroups (the
shape the aws-load-balancer-controller emits) left the action target empty and
CreateRule/CreateListener rejected it with MissingParameter. Flatten the first
target group from ForwardConfig when the flat field is absent.
* fix(ec2): mirror CreateTags/DeleteTags into subnet/vpc records
The generic S3 tag store and the per-resource KV records are disjoint:
DescribeSubnets/DescribeVpcs read tags from their KV record, while
CreateTags only wrote the generic store. Subnet tags applied after
create were therefore invisible to tag-filtered describes, breaking
aws-load-balancer-controller subnet auto-discovery (kubernetes.io/role/elb).
Write through CreateTags/DeleteTags to the owning subnet/vpc record so
tag-filtered describes observe them. Resource types the VPC service does
not own are skipped; the generic store stays their record of truth.
* test(daemon): pin synthetic capacity in host-dependent allocate tests
TestCanAllocate_CountEdgeCases/Mixed_instance_types and
TestHandleEC2DescribeInstanceTypes/NoFilterReturnsSupportedRegardlessOfAllocation
called rm.allocate against live-detected host capacity. allocate gates on
readMemAvailableGB (live /proc MemAvailable), so a box already running VMs
fails the allocation spuriously, breaking the preflight gate locally.
Pin hostVCPU/hostMemGB/reserved and nil readMemAvailableGB to a synthetic
host, matching the sibling Capacity_decreases_after_allocation subtest.
* fix(eks): route apiserver->pod traffic via agent tunnel (egress-selector cluster)
In the managed-CP topology the apiserver VM sits in the system CP VPC with
no route to the worker pod network in the unpeered customer VPC. k3s default
egress-selector-mode=agent tunnels only apiserver->kubelet, so kubectl
logs/exec work but apiserver->pod traffic (admission webhooks, aggregated
APIs) is attempted directly and times out -- the aws-load-balancer-controller
webhooks fail with context deadline exceeded, blocking Service/Ingress
creation cluster-wide.
Set egress-selector-mode=cluster so apiserver->pod/service traffic routes
through the agent's outbound tunnel, selected by the node hosting the
destination, without requiring inbound CP->worker reachability.
* feat: bump aws-load-balancer-controller addon bundle to v2.11.0
v2.8.1 predates the ALBSingleSubnet feature gate, so single-AZ spinifex
clusters fail Ingress reconcile (subnet resolver dedups to 1 < required 2)
and never provision an ALB. v2.11.0 honors --feature-gates=ALBSingleSubnet=true.
Replace the baked bundle: new CRDs (ingressclassparams + targetgroupbindings),
controller manifest, and image tag v2.11.0, re-applying the spinifex deltas
(IRSA SA annotation, node-minted webhook serving-cert secret, gateway-CA
secret, gateway aws-api-endpoints, caBundle on every webhook clientConfig,
alb IngressClass). Pick up the new ClusterRole configmaps rule. Drop v2.8.1.
* fix: point LBC at the gateway via AWS_ENDPOINT_URL (sdk-v2)
LBC v2.11 uses aws-sdk-go-v2, which keys --aws-api-endpoints on SDK
service IDs (e.g. 'Elastic Load Balancing v2'), not the legacy lowercase
names the bundle passed. Those overrides were silently ignored, so every
non-STS call (ec2/elbv2/acm) went to real AWS and failed TLS against the
gateway CA -- no ALB could provision.
Inject AWS_ENDPOINT_URL in the shared IRSA env block (sdk-v2 global
base-endpoint override; AWS_ENDPOINT_URL_STS still takes precedence for
STS) and drop the dead --aws-api-endpoints flag from the controller args.
* fix: synthesize taggable ARN for default listener rule
Gateway DescribeRules returned the synthetic IsDefault rule with a null
RuleArn. LBC read the arn-less default rule after creating a listener and
issued DescribeTags with an empty resource ARN, which the gateway rejected
with 400 MissingParameter, aborting reconcile.
Set a deterministic RuleArn on the default rule, resolve it back to its
parent listener in DescribeTags (empty tags) and DescribeRules by-arn.
Also disable shield/waf/wafv2 in the LBC bundle to drop unsupported calls.
* feat: inject ELB subnets into alb IngressClassParams for single-AZ ALB
LBC's tag auto-discovery never threads the ALBSingleSubnet feature gate, so a
single-AZ cluster (subnets sharing one AZ) dedups to 1<2 subnets and aborts
Ingress reconcile. Only the explicit-subnet path honors the gate.
Resolve the cluster's ELB-eligible subnets, dedup to one per AZ, and surface
them as EKS_ELB_SUBNET_IDS. The addon sync renders them into the alb
IngressClassParams .spec.subnets.ids so every Ingress takes the explicit path.
An empty set falls back to auto-discovery, preserving the native UX.
* fix: route LBC service clients to gateway via --aws-api-endpoints, link IngressClassParams
Live verification showed two gaps in the LBC addon bundle:
LBC installs a per-client BaseEndpoint resolver, so the global AWS_ENDPOINT_URL
is ignored for the ec2/elbv2/acm clients (calls hit real AWS, failing TLS).
Redirect them with --aws-api-endpoints keyed on the aws-sdk-go-v2 service IDs
(EC2, "Elastic Load Balancing v2", ACM, STS) rather than the legacy lowercase
names the flag never matched. Drop the misleading AWS_ENDPOINT_URL env; the
web-identity STS client still resolves via AWS_ENDPOINT_URL_STS.
The injected IngressClassParams was orphaned: the alb IngressClass had no
.spec.parameters, so LBC fell back to subnet auto-discovery (which fails on a
single-AZ cluster). Link the IngressClass to the IngressClassParams so the
explicit-subnet path is taken.
* fix: stamp EKS-parity providerID on worker nodes for LBC ip targets
k3s registers workers with providerID k3s://<name>, which the AWS Load
Balancer Controller rejects (providerID invalid for EC2 instances) when
resolving nodes for ip-mode target registration. Resolve the instance-id and
AZ from IMDSv2 at agent boot and set --kubelet-arg=provider-id=aws:///<az>/<id>
so LBC can map the node to its EC2 instance. On any IMDS miss the agent keeps
the default providerID and still starts.
* fix(elbv2): honor SubnetMappings in CreateLoadBalancer
LBC supplies ALB subnets via SubnetMappings, not the plain Subnets list.
createLoadBalancer only read input.Subnets, so ENI allocation was skipped,
VpcId/AZ stayed empty, and the HAProxy data-plane VM never launched — the
ALB went active but could not serve traffic. Add flattenSubnetIDs to read
both sources and reuse it in createLoadBalancer and desiredSubnetSet.
* fix(vm): capture GCInterval before spawning GC goroutine
TestStart_SweepsImmediatelyThenStopsOnCtxCancel mutates the package global
GCInterval and restores it in a defer, racing the Start goroutine's read at
time.NewTicker(GCInterval) under -race. Read GCInterval on the caller's
goroutine into a local before spawning so the global access is ordered with
the test's defer; the goroutine touches only the captured local.

feat(eks): unify eks-server + eks-agent into one eks-node AMI (#288)
* feat(eks): unify eks-server + eks-agent into one eks-node AMI Collapse the two K3s AMIs into a single spinifex-eks-node image whose role (server vs agent) is chosen per-instance at first boot, halving build time, storage, and CVE-rotation surface. - scripts/images/eks-node/: superset manifest + merged setup.sh; all role services baked but only crond + the new eks-node-role selector enabled. - eks-node-role first-boot selector reads SPINIFEX_K3S_ROLE, rc-update adds + starts the matching services (server: k3s + eks-token-webhook + k3s-first-boot publisher; agent: k3s-agent), records /etc/spinifex-eks/role, self-disables. Paths are env-overridable; eks-node-role_test.sh covers all five cases. - mulga-eks-etcd-snapshot.sh early-exits on agent nodes. - k3s_server_vm.go seeds SPINIFEX_K3S_ROLE=server into first-boot.env. - Makefile/dev-install: build-eks-node-image / import-eks-node-image replace the server+agent targets. - Delete scripts/images/eks-server + eks-agent. The launcher resolves the AMI by the spinifex:managed-by=eks tag, so running clusters (which hold the resolved AMI ID) are unaffected. AMI bake + cluster boot are operational integration steps, not yet run. * fix(eks): order eks-node-role after cloud-config/cloud-final The first-boot role selector reads /etc/spinifex-eks/first-boot.env, which cloud-init delivers via write_files in the cloud-config/cloud-final stages. The selector only depended on net+cgroups, so on a fast boot it could start before write_files landed and read a missing role env. Add an after-ordering on cloud-config + cloud-final so the env file is always present first. |
