- run nginx as non-root uid 101 and move container, service target, and target-group traffic from port 80 to 8080 - keep public ALB listeners on port 80 - note that the target-group port change replaces target groups on the next Pulumi update
- satisfy container hardening and code-scanning checks with an explicit runtime user - retain port 8080 target-group and container mappings for non-root nginx
- keep deployment guidance aligned with the hardened container base - document the frontend container's port 8080 target

Both nginx images now use
nginxinc/nginx-unprivileged:alpine(runs asnginx, uid 101) instead ofnginx:alpine(root). It's built from the same official entrypoint scripts, so the/etc/nginx/templates/*.templateenvsubst machinery the frontend relies on keeps working. Non-root can't bind port 80, so nginx moves to 8080, updated across every layer:deploy/config/nginx.conf.template+deploy/config/marketing-nginx.conf—listen 8080containerPort/portMappingsinalb.ts,per-pr-stack.ts,services.ts. The public ALB HTTP listener and ALB security group stay on 80/443.servicesSgalready allows TCP 0–65535 from the ALB SG, so no SG change was needed.containerPort, readiness-probe port and explicit ServicetargetPort: 8080infrontend.yaml/marketing.yaml(external Service ports unchanged).deploy/docker-compose.yml— host mapping now targets8080(external port unchanged,${FRONTEND_PORT:-3000}).deploy/README.md,deploy/docker/README.md,docs/self-hosting/docker-compose.md).Deploy note
Changing a TargetGroup's port forces replacement;
namePrefixgives create-before-destroy, but existing stacks will briefly re-register targets on their nextpulumi up. Per-PR preview stacks are ephemeral, so impact there is minimal. This PR's own preview deploy exercises the new port wiring end to end.Validation
