Container Apps 部署核心概念

Revision 策略

  • Single revision mode(默认):新版本上线,旧 revision 下线
  • Multiple revisions mode:蓝绿 / 金丝雀,老新并存,按流量权重分配
  • 生产推荐 single(简单);想做 A/B 用 multiple

Scaling

scale:
  minReplicas: 1    # 冷启接受度低 → ≥1;纯后台 / 非高可用 → 0
  maxReplicas: 10
  rules:
    - name: http-scaler
      http:
        metadata:
          concurrentRequests: "50"
    - name: cpu-scaler
      custom:
        type: cpu
        metadata:
          type: Utilization
          value: "70"

Ingress

ingress:
  external: true              # 外网可访问
  targetPort: 8000
  transport: auto             # 或 http2 / websocket
  allowInsecure: false        # 强制 HTTPS
  corsPolicy:
    allowedOrigins: ["https://lobechat.example.com"]
    allowedMethods: [GET, POST, PUT, DELETE, OPTIONS]
    allowCredentials: true
  ipSecurityRestrictions: []  # 白名单 IP(如果有)

Secrets 引用(推荐 Key Vault)

resource app 'Microsoft.App/containerApps@2024-03-01' = {
  properties: {
    configuration: {
      secrets: [
        {
          name: 'anthropic-key'
          keyVaultUrl: '${keyVault.properties.vaultUri}secrets/anthropic-api-key'
          identity: managedIdentity.id
        }
      ]
    }
    template: {
      containers: [{
        env: [
          { name: 'ANTHROPIC_API_KEY', secretRef: 'anthropic-key' }
        ]
      }]
    }
  }
}

永远不要用 value: 'xxx' 硬编码 secret。永远走 Key Vault + User-Assigned Managed Identity。

Celery Worker / Beat 的部署模式(CloudCostbrank 特有)

CloudCost 有 3 种进程:

  1. Web API → 普通 Container App(HTTP ingress)
  2. Celery Worker → Container App with no ingress + command: ["celery", "-A", "tasks", "worker"]
  3. Celery Beat → Container App Job(schedule trigger)或独立 Container App

建议用 Container App Job 跑 Beat:

resource beatJob 'Microsoft.App/jobs@2024-03-01' = {
  properties: {
    configuration: {
      triggerType: 'Schedule'
      scheduleTriggerConfig: {
        cronExpression: '0 2 * * *'
      }
    }
    template: {
      containers: [{
        image: 'acr.azurecr.io/cloudcost:latest'
        command: ['celery', '-A', 'tasks.celery_app', 'call', 'tasks.cloud_sync.sync_all_accounts']
      }]
    }
  }
}

部署失败排查路径

1. revision not active / 新 revision 不启动

az containerapp revision list -n <app> -g <rg> --query '[].{name:name,active:properties.active,reason:properties.provisioningState}'
az containerapp logs show -n <app> -g <rg> --tail 100 --revision <rev-name>

常见原因:

  • 启动命令 exit 非 0(看日志找 Python/Node 异常)
  • Liveness probe 失败(端口/路径不对)
  • 镜像 pull 失败(ACR 权限 or 网络)

2. Managed Identity 访问 Key Vault 失败

# 确认 Identity 有 Key Vault 的访问策略
az keyvault show -n <kv-name> --query 'properties.accessPolicies'
# 确认 Container App 绑定了 Identity
az containerapp identity show -n <app> -g <rg>

3. Ingress 502 / 503

  • App 启动成功但 502 → targetPort 不对
  • 持续 503 → replicas=0 且没收到流量,或健康检查失败

4. ACR 推送失败

az acr login --name <acr>
# 或:
docker login <acr>.azurecr.io -u <sp-id> -p <sp-secret>

与其它 Azure 服务的集成

Azure PostgreSQL

  • 用 private endpoint 连(不走公网)
  • 连接串走 Key Vault
  • SSL 必须 on(sslmode=require)
  • casdoor-internal 的 conf/app.conf 里有 PG 连接串,skip-worktree 保护

Azure Redis Cache

  • 和 ACA 在同 VNet 或 private endpoint
  • Persistence 按需开
  • chat-gw 用 LISTEN/NOTIFY 模式,确认 Redis 版本 ≥ 6

Azure Blob Storage

  • xiaoshou 存合同,gongdan 存工单附件
  • 用 SAS URL 上传(前端直传,不过后端)
  • SAS 过期时间 ≤ 15 分钟

Azure Service Bus

  • gongdan 的通知走 Service Bus Topic
  • subscriber 在 Container App worker 里

Azure Static Web Apps

  • xiaoshou 和 gongdan 的前端
  • Build 和 deploy 同一个 workflow
  • API routes 可以指向 ACA 的 Container App

成本优化

1. 合理设置 minReplicas

  • 高可用业务(chat-gw / casdoor) → minReplicas=2
  • 内部工具(CloudCost worker) → minReplicas=0(有流量再拉起)

2. 用 Consumption plan vs Dedicated

  • 流量稳定 + 预算有限 → Dedicated
  • 突发流量 → Consumption

3. 共享 Container Apps Environment

  • 同一个 Environment 下的多个 App 共享 VNet
  • 6 个业务 App 都放在同一个 Environment 降低运维复杂度

4. 日志成本

  • Log Analytics 保留 < 30 天(除非合规要求)
  • 日志级别 production 用 INFO,不要 DEBUG

工作流(改部署配置时)

1. 找到对应的部署 workflow

ls /workspace/<repo>/.github/workflows/*deploy*

2. 改 Bicep / workflow 时,验证 bicep 语法

az bicep build --file deploy/main.bicep

3. dry-run 看会改什么

az deployment group what-if \
  --resource-group <rg> \
  --template-file deploy/main.bicep \
  --parameters @deploy/main.parameters.json

4. 改 conf/app.conf(casdoor-internal)

  • 它 skip-worktree,不能通过 git push 改到服务器
  • 必须手动 SSH 到 runner 或走 az containerapp exec 改
  • 强烈建议改成用环境变量 + Key Vault 引用替代

红线

  • ❌ 不要把 secret 写到 Bicep 的 value 字段
  • ❌ 不要在生产 Container App 上直接 az containerapp update --image ... 手动改(应走 CI/CD)
  • ❌ 不要删除 revisions(保留历史便于回滚)
  • ❌ 不要给 Container App 开 --external-enabled 除非真要外网访问
  • ❌ 不要 skip deployment smoke test(post-deploy-smoke.yml 的存在是有原因的)

输出

汇报:改了哪个 Bicep / workflow、期望的 ACA 资源变化、Key Vault 新引用、预计对运行中服务的影响、回滚方法。
