Walkthrough

Thêm pipeline Tekton “db-migrate” và trigger, mở rộng Operator để sinh PGRST_DB_URI và inject DATABASE_URL/DB_NAME, cập nhật schema/CRD/inputs, nâng cấp portal backend/actions/config, bổ sung template PostgREST/Hasura/.NET/Spring Boot, và thêm các script thiết lập cùng Taskfile.

Operator database secret/URI formatting, env injection, and reconciliation apps/operator/internal/controller/database/*, tests	Generates PGRST_DB_URI, formats Postgres URI, injects DB_NAME/DATABASE_URL, centralizes dbType, computes effective DB name/port, bumps default Postgres 18.3; updates tests.
Tekton tasks/pipelines/triggers and CUE builder integration cue/definitions/tekton/*, cue/engine/tekton_builder.cue, apps/operator/tekton/pipeline.yaml, tests, docs	Adds db-migrate pipeline, db-migrate/postgrest-reload tasks, trigger bundles and URL rewrites, manifest yq updates, default images to node:24; wires builder and tests; adds testing guide.
Portal backend actions, router improvements, and app config apps/portal/packages/backend/*, apps/portal/plugins/helios-backend/src/service/router.ts, apps/portal/app-config.yaml	Adds kubernetes:create-secret, extends kubernetes:apply, registers actions; improves /info to iterate secret/labels; updates CORS, Gitea, ArgoCD target, catalog locations, kubectl proxy locator.
Example templates: PostgREST, Hasura, .NET, Spring Boot, and related catalog/org apps/portal/examples/*	Introduces full Backstage templates and content for PostgREST/Hasura/.NET/Spring Boot; updates advanced example comment; tweaks NestJS description; adds org alias.
Setup scripts, Taskfile wiring, CI lint bump, and environment samples Taskfile.yml, scripts/*, .env.example, .gitignore, apps/operator/.github/workflows/lint.yml, apps/operator/Makefile	Adds CoreDNS setup, externalizes Windows steps, credential scripts, start/test scripts, prereq checks; updates env/gitignore; bumps golangci-lint; minor dev:portal change.

Poem

Tai thỏ rung rinh trước gió pipeline,
Git đẩy là Tekton chạy thẳng một line.
Migrate xong, pgrst nghe “ding!” rồi reload,
Operator rót URI, env vào pod.
Template nảy mầm: .NET, Spring, Hasura, REST—
Thỏ gõ “deploy!”—cỏ xanh khắp commit fest. 🐇✨
