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.
|
||||

|
||||
|
||||
* Boot order and deploy sequencing:
|
||||
[Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md)
|
||||
|
||||
* Circular dependency in rollout pipelines:

||||
|
||||
* First call failure after deploy:

|
||||
|
||||
* Schema and payload contracts:
|
||||
[Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
|
||||
|
||||
* Live monitoring and rollback:

||||

|
||||
|
||||

|
||||
|
||||
## 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.

|
||||
|
||||
---
|
||||
|
||||
* **Pipeline deadlocks waiting for services**
|
||||
|
||||
Deploy order incorrect or circular dependency exists.

|
||||
|
||||
* **Migration and deploy run simultaneously**
|
||||
|
||||
Application reads partially migrated schema.

|
||||
|
||||
* **Canary passes but full rollout fails**
|
||||
|
||||
Canary environment differs from production configuration.

## 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.
