Serverless platforms simplify infrastructure but often hide **deployment complexity** behind CI/CD pipelines. When build steps, environment configuration, and rollout order are not carefully controlled, deployments can appear successful while services fail at runtime. This page provides guardrails to make serverless CI/CD pipelines predictable, observable, and safe to roll out across regions. --- ## When to use this page * Deployments succeed but the first requests fail. * New releases break environment variables or secrets. * Serverless functions deploy but cannot reach dependencies. * CI pipelines run migrations and application rollout simultaneously. * Canary deployment passes but full rollout causes failures. --- ## Open these first * Boot order and deploy sequencing: [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) * Circular dependency in rollout pipelines: [Deployment Deadlock](https://github.com/onestardao/WFGY/blob/main/ProblemMap/deployment-deadlock.md) * First call failure after deploy: [Pre-Deploy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md) * Schema and payload contracts: [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) * Live monitoring and rollback: [Debug Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/debug_playbook.md) --- ## Acceptance targets * CI pipeline completes without manual intervention. * Deployment artifacts reproducible across environments. * No increase in error rate after rollout. * Environment variables and secrets consistent across revisions. * Canary deployment accurately predicts full rollout behavior. For RAG pipelines: * ΔS(question, retrieved) drift ≤ 0.03 after deploy. * Index versions identical across environments before traffic. --- ## Fix in 60 seconds 1. **Separate build, migration, and deploy stages** CI pipelines must isolate artifact build, schema migration, and application rollout. 2. **Version artifacts explicitly** Every deploy should carry: * `release_id` * `schema_rev` * `index_hash` 3. **Use canary deployments** Roll out to a small percentage of traffic before global rollout. 4. **Gate deploy on health probes** Services should not receive traffic until environment variables, secrets, and dependencies verify successfully. 5. **Enable automated rollback** If error rate or latency spikes, pipeline must revert automatically. --- ## Patterns that work * **Immutable build artifacts** Build once and promote the same artifact across staging and production. * **Pipeline stage contracts** Each stage verifies artifacts, migrations, and health before continuing. * **Canary plus gradual rollout** Deploy first to a small subset of users or a single region. * **Deployment freeze windows** Prevent simultaneous deploys across services that share dependencies. --- ## Typical breakpoints → exact fix * **Deploy succeeds but service crashes immediately** Environment variables missing or incompatible. Open: [Pre-Deploy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md) --- * **Pipeline deadlocks waiting for services** Deploy order incorrect or circular dependency exists. Open: [Deployment Deadlock](https://github.com/onestardao/WFGY/blob/main/ProblemMap/deployment-deadlock.md) --- * **Migration and deploy run simultaneously** Application reads partially migrated schema. Open: [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) --- * **Canary passes but full rollout fails** Canary environment differs from production configuration. Open: [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) --- ## Minimal recipes you can copy ### A) CI pipeline stages ```txt Pipeline stages 1. Build artifact 2. Run tests 3. Execute migrations 4. Deploy canary revision 5. Verify health probes 6. Gradual rollout 7. Promote release ```` --- ### B) Deployment contract ```txt Deployment metadata release_id = r2025-08-30 schema_rev = sc-21 index_hash = a1b2c3 Services start only if versions match expected values. ``` --- ### C) Rollback rule ```txt Rollback trigger If error_rate > baseline + 2% or latency > SLO threshold Then: - revert to previous revision - pause pipeline - alert operator ``` --- ## Observability you must add * Deployment success and rollback metrics. * Error rate by revision. * Environment variable mismatch detection. * CI pipeline duration and stage failure counts. * Canary vs production performance comparison. --- ## Verification * Deployment completes with no service restarts. * Canary and full rollout metrics match expected behavior. * Environment variables consistent across revisions. * No schema mismatches or runtime configuration errors. --- ## When to escalate * CI pipeline repeatedly fails in the same stage. * Deployments succeed but services remain unhealthy. * Canary behavior diverges significantly from production. * Rollback fails or leaves system in inconsistent state. Investigate environment configuration, pipeline orchestration, and dependency readiness before retrying deploy. --- ### 🔗 Quick-Start Downloads (60 sec) | Tool | Link | 3-Step Setup | | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------- | | **WFGY 1.0 PDF** | [Engine Paper](https://github.com/onestardao/WFGY/blob/main/I_am_not_lizardman/WFGY_All_Principles_Return_to_One_v1.0_PSBigBig_Public.pdf) | 1️⃣ Download · 2️⃣ Upload to your LLM · 3️⃣ Ask “Answer using WFGY + ” | | **TXT OS (plain-text OS)** | [TXTOS.txt](https://github.com/onestardao/WFGY/blob/main/OS/TXTOS.txt) | 1️⃣ Download · 2️⃣ Paste into any LLM chat · 3️⃣ Type “hello world” — OS boots instantly | --- ### Explore More | Layer | Page | What it’s for | | ------------- | --------------------------------------------------------------------------- | ----------------------------------------------------- | | ⭐ Proof | [WFGY Recognition Map](/recognition/README.md) | External citations, integrations, and ecosystem proof | | ⚙️ Engine | [WFGY 1.0](/legacy/README.md) | Original PDF tension engine and early logic sketch | | ⚙️ Engine | [WFGY 2.0](/core/README.md) | Production tension kernel for RAG and agent systems | | ⚙️ Engine | [WFGY 3.0](/TensionUniverse/EventHorizon/README.md) | TXT based Singularity tension engine | | 🗺️ Map | [Problem Map 1.0](/ProblemMap/README.md) | Flagship 16 problem RAG failure taxonomy | | 🗺️ Map | [Problem Map 2.0](/ProblemMap/wfgy-rag-16-problem-map-global-debug-card.md) | Global Debug Card | | 🗺️ Map | [Problem Map 3.0](/ProblemMap/wfgy-ai-problem-map-troubleshooting-atlas.md) | AI troubleshooting atlas | | 🧰 App | [TXT OS](/OS/README.md) | .txt semantic OS | | 🧰 App | [Blah Blah Blah](/OS/BlahBlahBlah/README.md) | Abstract Q&A | | 🧰 App | [Blur Blur Blur](/OS/BlurBlurBlur/README.md) | Text-to-image generation | | 🏡 Onboarding | [Starter Village](/StarterVillage/README.md) | Guided entry | If this repository helped, starring it improves discovery so more builders can find the docs and tools.
