Jon Chery 491ba78768 feat(P33): uptime-kuma primitive + deploy-uptime pipeline stage (REQ-88..91)
---ci---
project: acdl
phase: 33
milestone: v1.8
status: execute
---/ci---

- New uptime L1 primitive (aws:ecs:uptime-service) deploying uptime-kuma
  on ECS Fargate with feature_flag_enabled, monitored_endpoints,
  static_checks, alert_channels (Teams/email/SMS/GitHub issues).
- Adapter emits ECS Fargate task + service when feature_flag_enabled=true;
  emits nothing when false. Container image louislam/uptime-kuma:1.
- New deploy-uptime pipeline stage in pipelines/deploy.yaml (after
  publish-outputs, before comment-outputs). Now 9 stages.
- run_platform.sh --deploy-uptime flag + automatic uptime deployment
  after L2 module (separate state $WORK/uptime-tf). Endpoints from L2
  outputs passed as monitored_endpoints. Feature flag from
  inputs.uptime_enabled (default true).
- scripts/seed_uptime_monitors.py for post-deploy monitor seeding via
  uptime-kuma API.
- Registered in registry.json (14 modules total).

Tests: +6 (312 -> 318). All pass.

ACDL Modules

Reusable building blocks for cloud infrastructure. Each module is self-documented with a README.md following the template.

How the modules work

There are two kinds of module:

  • Primitives — a single cloud resource or a small group of related resources (e.g. a VPC with subnets and routing). Each primitive has an interface.json declaring its inputs and outputs, and a README.md in plain language.
  • Modules — a pattern that references multiple primitives to deploy a complete stack (e.g. an ECS Fargate microservice). Each module has a composition.json declaring its children and wires.

The substrate adapter (adapters/terraform/adapter.py) compiles a module instance to infrastructure. Each module's README documents which resources it creates.

Primitives

Module What it creates README
s3 aws_s3_bucket — a single S3 bucket README
vpc aws_vpc + aws_subnet + aws_route_table + aws_internet_gateway — VPC with subnets and routing README
ecs-cluster aws_ecs_cluster — ECS Fargate cluster README
ecs-service aws_ecs_task_definition + aws_ecs_service — Fargate service with task definition README
iam-role aws_iam_role — IAM role with assume-role policy README
alb aws_lb + aws_lb_target_group + aws_lb_listener — Application Load Balancer README
ecr aws_ecr_repository — ECR container image repository README
cloudfront aws_cloudfront_distribution + aws_cloudfront_origin_access_control — CloudFront distribution with S3 origin via OAC README
waf aws_wafv2_web_acl — WAFv2 Web ACL (CloudFront-scoped) README

Modules

Module What it references README
microservice 6 primitives (vpc, cluster, ecr, iam-role, alb, ecs-service) README
static-assets 3 primitives (s3, cloudfront, waf) README

Registry

Module versions are tracked in registry.json. Both primitives and modules are registered.

Template

New modules should use README-TEMPLATE.md as their starting point.

Module patterns (roadmap)

The current composition.json mechanism is a thin pattern layer. A future redesign will let a consumer dynamically create a module directly from the contract file (an agentic "composition" flow). That is on the roadmap, not implemented today.
