From f420773b0e882e08cb44fee7ed0bb0422cd06e10 Mon Sep 17 00:00:00 2001 From: Austin Zhai Date: Fri, 3 Apr 2026 09:25:47 +0800 Subject: [PATCH] Feat/container multi os (#98) * Add comprehensive in-process test framework Add unit tests for exchange layer, E2E integration tests, security tests (race + fuzz), and Go benchmark tests replacing the old shell-script-based bench programs. All tests run in-process without requiring an external frontier process. Suppress klog and armorigo log noise in all test files. Co-Authored-By: Claude Sonnet 4.6 * Update build configs, Dockerfiles and dependencies Update Makefile with new targets, consolidate frontier_all.yaml config, bump base image versions in Dockerfiles, and update go.mod/go.sum.

Use it when brand colors or style guidelines, visual formatting, or company design standards apply. +global + + + +canvas-design +Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations. +global + + + +doc-coauthoring +Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks. +global + + + +docx +"Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of \"Word doc\", \"word document\", \".docx\", or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a \"report\", \"memo\", \"letter\", \"template\", or similar deliverable as a Word or .docx file, use this skill.

This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in my downloads\") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved." +global + + + + + + diff --git a/Makefile b/Makefile index afc2826..aa5b45f 100644 --- a/Makefile +++ b/Makefile @@ -52,6 +52,12 @@ help: @echo " make frontier-windows-amd64 - Build frontier for Windows amd64" @echo " make frontier-windows-arm64 - Build frontier for Windows arm64" @echo "" + @echo "Docker images (REGISTRY=, VERSION=):" + @echo " make image-frontier - Build frontier image (current platform)" + @echo " make image-frontier-linux - Build frontier image for linux/amd64" + @echo " make image-frontlas - Build frontlas image (current platform)" + @echo " make image-frontlas-linux - Build frontlas image for linux/amd64" + @echo "" @echo "Other targets:" @echo " make clean - Clean local build artifacts" @echo " make clean-dist - Clean cross-compilation artifacts" @@ -419,10 +425,18 @@ uninstall-systemd: image-frontier: docker buildx build -t ${REGISTRY}/frontier:${VERSION} -f images/Dockerfile.frontier . +.PHONY: image-frontier-linux +image-frontier-linux: + docker buildx build --platform linux/amd64 -t ${REGISTRY}/frontier:${VERSION} -f images/Dockerfile.frontier . + .PHONY: image-frontlas image-frontlas: docker buildx build -t ${REGISTRY}/frontlas:${VERSION} -f images/Dockerfile.frontlas . +.PHONY: image-frontlas-linux +image-frontlas-linux: + docker buildx build --platform linux/amd64 -t ${REGISTRY}/frontlas:${VERSION} -f images/Dockerfile.frontlas . + .PHONY: image-gen-api image-gen-api: docker buildx build -t image-gen-api:${VERSION} -f images/Dockerfile.controlplane-api . diff --git a/docs/frontier-technical.md b/docs/frontier-technical.md new file mode 100644 index 0000000..8b8a7f9 --- /dev/null +++ b/docs/frontier-technical.md @@ -0,0 +1,1876 @@ +# Frontier 技术原理 + +## 目录 + +1.

资源的创建、更新、删除 +2. **Reconcile 触发**: 当 CRD 变更时，触发 Reconcile 函数 +3. **状态对比**: 对比期望状态（Spec）和实际状态（Status） +4. **资源创建/更新**: 创建或更新 Deployment、Service 等资源 +5. **状态更新**: 更新 CRD 的 Status 字段 + +**时序图：** + +```

+``` + +#### 资源管理 + +**Deployment 创建：** + +Controller 根据 CRD Spec 创建 Frontier 和 Frontlas 的 Deployment。 + +**关键配置：** + +1. **环境变量注入**: + - Frontier 地址和端口 + - Frontlas 地址 + - Redis 配置 + +2. **Pod 反亲和性**: + - 确保 Frontier Pod 分布在不同节点 + - 提高可用性 + +3. **资源限制**: + - 可配置 CPU 和内存限制 + +**关键代码：** + +```go +func (r *FrontierClusterReconciler) ensureFrontierDeployment(ctx context.Context, fc v1alpha1.FrontierCluster) error { + // 构建容器配置 + container := container.Builder(). + SetName("frontier"). + SetImage(image). + SetEnvs([]corev1.EnvVar{ + {Name: FrontierServiceboundPortEnv, Value:

}) + + // 创建 Deployment + deploy := deployment.Builder(). + SetReplicas(fc.FrontierReplicas()). + SetPodTemplateSpec(podTemplateSpec). + Build() + + deployment.CreateOrUpdate(ctx, r.client, deploy) +} +``` + +#### 自动扩缩容 + +**水平扩缩容：** + +1. **修改 Replicas**: 用户修改 CRD 中的 `replicas` 字段 +2. **Controller 检测**: Controller 检测到 Spec 变更 +3. **更新 Deployment**: 更新 Deployment 的 Replicas +4. **K8s 调度**: Kubernetes 自动创建或删除 Pod +5. **状态同步**: Controller 更新 CRD Status + +**垂直扩缩容：** + +- 通过修改 Deployment 的资源限制实现 +- 需要重启 Pod，影响较大 + +#### CRD Status 管理 + +**Status 字段：** + +```go +type FrontierClusterStatus struct { + Phase Phase `json:"phase"` // Running, Failed, Pending + Message string `json:"message"` // 状态描述 +} +``` + +**状态转换：** + +- **Pending**: Deployment 未就绪 +- **Running**: 所有 Deployment 就绪 +- **Failed**: 创建或更新资源失败 + +**关键代码：** + +```go +func (r *FrontierClusterReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error) { + // 检查 Deployment 就绪状态 + frontierIsReady := deployment.IsReady(currentFrontierDeployment, fc.FrontierReplicas()) + frontlasIsReady := deployment.IsReady(currentFrontlasDeployment, fc.FrontlasReplicas()) + + if !frontierIsReady ||

Frontier + - 支持连接漂移和自动重连 + +3. **高可用性** + - 多 Frontier 实例提供冗余 + - Frontlas 支持多实例部署 + - Redis 支持高可用模式 + +4. **声明式管理** + - 通过 CRD 声明集群配置 + - Controller 自动管理资源 + - 支持自动扩缩容 + +--- + +## 总结 + +Frontier 通过以下机制实现了高效的客户端管理和消息转发： + +1. **灵活的认证机制**：支持 Meta 信息传递和灵活的 ID 分配策略 +2. **可靠的上下线管理**：保证数据一致性和并发安全 +3. **高效的 Exchange 转发**：实现 Service 和 Edge 的解耦，支持消息、RPC 和 Stream 的透明转发 +4. **集群模式支持**：通过 Frontlas 实现多 Frontier 实例的协调管理，支持水平扩展和高可用 + +这些设计使得 Frontier 能够支持大规模、高并发的边缘计算场景。 diff --git a/etc/frontlas.yaml b/etc/frontlas.yaml index b563d0a..247a4cc 100644 --- a/etc/frontlas.yaml +++ b/etc/frontlas.yaml @@
