* feat(ecs): provision EC2 container-instance capacity via IMDS instance-role
Adds a ProvisionCapacity gateway action that launches spinifex-ecs-node
EC2 instances which register as ECS container instances, fixing
RESOURCE:placement when a cluster has no capacity.
Agent control-plane now SigV4-signs gateway calls with instance-role
credentials read from IMDS (no static keys seeded in user-data). The
gateway already verifies STS/temp creds, so the instance role carries an
ecs:* policy + ec2 trust; ensureECSInstanceProfile find-or-creates the
ecsInstanceRole instance profile attached at launch.
Backend resolves the spinifex-ecs-node AMI by spinifex:managed-by=ecs
tag, renders keyless user-data, and launches via the customer
RunInstances path. Frontend adds a hand-signed JSON-1.1 ProvisionCapacity
call, a provision-capacity dialog on the container-instances tab, and the
ECS console section nav + system-image gating.
* feat: auto-assign EIPs to awsvpc service tasks; add ECS task/service detail pages
Wire AssignPublicIp=ENABLED through the service reconciler so awsvpc service
tasks automatically allocate and associate an Elastic IP on the RUNNING
transition, and release it on STOP. assignTaskPublicIP/releaseTaskPublicIP
mirror the target-group registration hooks in recordTaskState and forceStopTask;
the public IP and allocation ID are persisted on the task record and surfaced in
DescribeTasks attachments as publicIPv4Address.
Add AWS-parity ECS task and service detail pages showing private and public
endpoints, container state, and networking configuration, reachable by clicking
a task or service in the cluster tabs.
* test: cover natsEIPManager allocate/associate/release over NATS
* feat(ecsgw): on-VM SigV4 client for the ECS agent→gateway channel
Adds internal/ecsgw, the twin of internal/eksgw: a TLS + SigV4 (service "ecs")
client the ecs-agent will use to reach the AWS gateway over HTTPS instead of
connecting to host NATS directly. Calls are AWS JSON 1.1 with an X-Amz-Target
action; the gateway relays onto ecs.* host-side, keeping NATS cluster-internal.
* feat(ecs): SubmitTaskStateChange gateway action → recordTaskState
Wires the AWS-API SubmitTaskStateChange action end to end (gateway action →
ecs.SubmitTaskStateChange NATS → daemon → Service.SubmitTaskStateChange) so a
gateway-routed agent reports task state without touching the NATS bus. The
handler maps the SDK input onto the same bus.TaskState shape and converges on
recordTaskState; the account is authoritative from the SigV4 caller, so an
instance cannot report state for another account's task.
* feat(ecs): durable assign KV inbox + PollAssignments gateway action
Scheduler writes task assigns into a per-instance KV inbox
(clusters/{cluster}/assignments/{instance}/{task}) instead of a
fire-and-forget core-NATS publish, and a new PollAssignments gateway
action lets a gateway-routed agent drain its inbox over TLS+SigV4.
At-least-once: an unacked assign is re-delivered on the next poll;
the agent acks accepted assigns (AckTaskIDs) and STOPPED transitions
reclaim stale inbox entries. The Poll response carries bus.Assign with
an RFC3339 time, so it is encoded with encoding/json (RawJSONActions)
rather than the jsonutil epoch-second marshaler.
* feat(ecs-agent): rewire control-plane off NATS onto the AWS gateway
The agent no longer connects to NATS. It registers, heartbeats, reports
task state, and receives assignments entirely through the AWS gateway
over TLS+SigV4, using seeded IAM credentials — keeping the NATS bus
host-internal and closing the trust-boundary gap (a tenant container
instance must not hold a shared bus token).
- controlPlane seam over ecsgw.Client replaces the NATS publisher:
Register (RegisterContainerInstance), SubmitTaskState
(SubmitTaskStateChange), PollAssignments.
- Heartbeat folds into a periodic idempotent re-register (refreshes
LastSeen); bus.Heartbeat is dropped from the agent.
- subscribeAssign (NATS subscribe) becomes a poll loop: drain the
inbox, dispatch each assign once, ack accepted taskIDs on the next
poll (at-least-once).
- config: ECS_ACCESS_KEY / ECS_SECRET_KEY / ECS_POLL_INTERVAL added,
ECS_NATS_URL removed; cloud-init initd seeds the IAM creds.
Tests move from the NATS publisher fake to a controlPlane fake.
* feat(ecs): cloud-init cred-seed + ecs-node bring-up script
ECS container instances are plain EC2 booted from the spinifex-ecs-node
AMI (AWS-faithful: no ECS-specific launch API). This renders the
cloud-init user-data that seeds /etc/spinifex-ecs/agent.env (gateway
URL/CA/region/cluster + IAM creds) and the gateway CA, then runs the
instance. The agent registers, heartbeats, polls assignments, and
reports task state entirely through the AWS gateway over TLS+SigV4 —
never NATS.
The guest dials the customer-facing gateway address (network advertise
IP), not the mgmt bridge, mirroring the EKS GatewayURL/AddonGatewayURL
split. Seeds the system key for now; scoped per-instance creds are a
follow-up (4g task-role endpoint).
* fix(ecs): reconcile dev merge — restore #418 ENI release + netns wiring
The 'Merge branch dev' resolution dropped code where Sprint 4d (#418,
awsvpc ENI-per-task) and the gateway control-plane rewrite (#419) touch
the same paths:
- recordTaskState STOPPED branch: reclaimTaskENI was clobbered by
reclaimAssignInbox; both are needed (release the task ENI AND drain the
KV inbox). Restores TestRecordTaskState_Awsvpc_ReleasesENIOnStopOnce.
- ecs-agent Agent: the netns field, its init, and the setupTaskNetns/
teardownTaskNetns wrappers were lost when the controlPlane Agent struct
won the merge, leaving taskrun.go calling undefined methods.
- eni_test assign assertion read the assign over NATS; #419 delivers it via
the durable KV inbox, so it now polls via PollAssignments.
- taskrun_test netns cases used the removed historyPub fake; switched to
fakeCP to match the controlPlane seam.
