* feat(infra): migrate pipeline and Grafana to HCP Terraform (PLAT-75)
Move apm-wo-analysis into seahaven-prod under workspace apm-wo-analysis-prod
with in-repo hcptf/githubdeploy IAM, stub Lambdas, and GitHub Actions zip CD.
* chore(iam): add Checkov skip comments for HCP IAM documents
Pre-push HIGH findings are the DLM snapshot describe, tagged EC2 creates,
exec boundary DescribeLogGroups star, and the drop-uploader user policy.
Grafana rejected the datasource with 'trying to use non-allowed auth method
ec2_iam_role: Failed to create client' — the plugin's allowed_auth_providers
defaults to default,keys,credentials and excludes ec2_iam_role. Switch authType
to 'default' (AWS SDK default chain), which on EC2 resolves to the instance role
via IMDS (still no static keys) and is allowed out of the box.
The one non-serverless piece — Grafana OSS on a t4g.small (AL2023, ARM64) in the
imported seahaven-vpc, fronted by an internet-facing ALB locked by SG to the
office CIDRs (no Client VPN exists, so "VPN-only" = office-IP restriction, the
syslog-server pattern). Instance in private subnets, reachable only from the ALB
SG, administered via SSM Session Manager (no SSH/key pair).
grafana_stack.py: ALB (HTTPS, *.seahaven.com cert, open=False so the SG office
rules aren't undone by an auto 0.0.0.0/0), instance role (Athena query + Glue
read + S3 analytics/athena-results, no static keys), Route53 grafana.seahaven.com
alias, gp3 root volume RETAINed, daily DLM snapshot of the tagged instance, and a
BucketDeployment that uploads grafana/ to the S3 config prefix.
grafana_userdata.sh: install Grafana OSS, pin the Athena datasource plugin, write
grafana.ini (root_url grafana.seahaven.com, kiosk embedding), sync provisioning +
dashboards from S3 on boot, and a systemd timer re-syncs every 15 min so repo
edits land without an instance rebuild.
Dashboard (grafana-author agent, grafana/dashboards/apm-work-orders.json, uid
apm-wo so the Slack 📊 button resolves): 7 panels — category distribution,
escalation summary, action/routine, escalations-by-site, trend time-series over
dt (the new capability), filterable WO table (5 template vars, escalation row
coloring, CSV export, no APM links), and the mismatch panel. Datasource uid
"athena" pinned in the provisioning yaml.
Tests: tests/test_grafana_synth.py — ALB admits only the office CIDRs on 443
(caught and fixed a default 0.0.0.0/0 listener rule), instance only-from-ALB,
no static keys, scoped instance role + SSM, gp3+retained root volume, daily DLM
backup, grafana.seahaven.com alias. 57/57 tests pass; full cdk synth green.
Stand up the Phase 0 CDK scaffold for the daily APM work-order
analysis pipeline: two-stack CDK app (pipeline + grafana), classifier
and slack-post Lambda packages, dashboards-as-code, the local
drop-folder uploader, and a classifier smoke-test placeholder.
Wire CI/CD to the org reusable workflows: ci.yaml -> ci-python-sam
(ruff + cdk synth) and deploy.yaml -> cd-cdk (OIDC, cdk deploy --all).
Pin aws-cdk-lib==2.253.1; Lambdas target Python 3.12 / arm64.
Rewrite .gitignore to the org Python-CDK standard so the source-of-
truth files (CLAUDE.md, docs/, .claude/agents) are tracked while build
artifacts (.venv, cdk.out, caches) stay ignored.
Domain logic, stack resources, and dashboards are stubbed and filled
in across Phases 1-5 (docs/BUILD.md). cdk synth is green for both
stacks; ruff check/format pass.
