`daytona.create()`） + +- **产物类型**：服务端按 Dockerfile 内容 + 上下文哈希计算的匿名快照（无名字、无 `id` 暴露给调用方） +- **存储位置**：Daytona 平台内部 Object Storage（S3 兼容），调用方不可直达底层 +- **管理 API**：**无**。调用方拿不到 ID，也不能 list/delete 这一层产物 +- **生命周期**：服务端自动缓存 **24 小时**，过期清理 +- **用户控制**：`Image.from_dockerfile(force_build=True)` 强制重建当次 + +#### B. 命名 Snapshot（`AsyncSnapshotService.create()`） + +- **产物类型**：注册到 Daytona 数据库的 Snapshot 对象（`id` / `name` / `state` / `image_name` / `size` / `cpu/gpu/mem/disk` 等字段）。**Snapshot 不是标准 Docker 镜像**，是平台专有快照格式 +- **存储位置**：同上，但产物在数据库中有名字、有状态、可查询 +- **管理 API**：完整的 CRUD 接口 + + ```python + class AsyncSnapshotService: + async def list(page=None, limit=None) -> PaginatedSnapshots + async def get(name: str) -> Snapshot + async def create(params: CreateSnapshotParams, *, on_logs=None, timeout=0) -> Snapshot + async def delete(snapshot: Snapshot) -> None + async def activate(snapshot: Snapshot) -> Snapshot # 激活归档态的 Snapshot + ``` +- **生命周期**：永久持有，需手动删除 +- **用户控制**：`snapshot.delete()` / Dashboard / CLI + +#### 构建上下文传输 + +`Image` 对象的 `_context_list`（`COPY` 引用的本地文件）通过 `AsyncObjectStorage.upload()` 上传，bucket 由服务端 `get_push_access()` 动态下发（SDK 的默认 fallback bucket 是 `daytona-volume-builds`，但生产环境通常不用 fallback）。上传产生 content hash 数组随 `CreateBuildInfo(context_hashes=..., dockerfile_content=...)` 提交给服务端。 + +--- + +### E2B — 命名 Template + +- **产物类型**：注册到 E2B 后端的 Template（暴露给调用方的标识是 `template_id` 或 `alias`）。底层是 Firecracker microVM 快照（rootfs/memfile/snapfile），但调用方不直接接触这一层 +- **存储位置**：E2B 平台云对象存储，元数据存数据库 +- **管理 API**： + + ```python + class AsyncTemplate: + @staticmethod + async def build(template, name=None, *, alias=None, cpu_count=2, memory_mb=1024, skip_cache=False) -> BuildInfo + @staticmethod + async def alias_exists(alias: str) -> bool # REST GET /templates/aliases/{alias} + # 删除走 CLI: `e2b template delete ` + ``` +- **生命周期**：永久保留，无自动清理；构建失败时服务端自动回收已上传对象 +- **用户控制**： + - 缓存复用：alias 相同则复用（Harbor 把 `dirhash[:8]` 嵌入 alias 实现内容寻址） + - 强制重建：`AsyncTemplate.build(skip_cache=True)` + - 删除：`e2b template delete` CLI / API + +#### 补充：服务端实现细节（如不关心可跳过） + +E2B 后端把 Dockerfile 拆成阶段流水线 `BaseBuilder → UserBuilder → StepBuilders(每条指令) → PostProcessing → Optimize`，每阶段计算 SHA-256 哈希作为缓存 key（输入含 `provision_version`、`disk_size`、`from_image`、`step_args`、`files_hash` 等），命中即跳过该阶段。每阶段产出 dirty-block 差异层(`rootfs.ext4.header`、`memfile.header`)。最终产物按 `buildID` 组织在 GCS/S3 (`TEMPLATE_BUCKET_NAME`)，构建缓存索引在另一个 bucket (`BUILD_CACHE_BUCKET_NAME`)。这部分对调用方完全不可见，仅决定缓存命中率。 + +--- + +### Modal — 隐式哈希缓存（无显式产物） + +- **产物类型**：文件系统快照，**调用方完全无法引用**——SDK 不返回 `image_id` 给用户代码持有，下次调用时按内容重新计算哈希查找缓存 +- **存储位置**：Modal 平台内部，完全抽象 +- **管理 API**：**无**列表 / 查询 / 删除 API。Image 只是一个声明式 `_Image` 对象，调用 `Sandbox.create(image=image)` 时通过 gRPC `ImageGetOrCreate(image_definition_pb, force_build=...)` 提交给服务端，服务端按内容哈希返回已有或触发新构建 +- **生命周期**：随镜像定义自动缓存；定义变化（Dockerfile 内容、build_args、context_files、`force_build`）即触发重建 +- **用户控制**： + - 强制重建：`Image.from_dockerfile(force_build=True)` 或 `MODAL_FORCE_BUILD=1` 环境变量 + - 无手动删除入口（旧产物由平台按使用情况和容量策略自行回收） + +--- + +### Runloop — 命名 Blueprint + 独立的 build context 对象 + +- **产物类型**：Blueprint（平台托管的容器镜像），独立有 `id` / `name` / `status`(`queued`/`provisioning`/`building`/`failed`/`build_complete`) / `create_time_ms`。同名 Blueprint 可共存多个版本 +- **存储位置**：Runloop 平台内部 +- **管理 API**： + + ```python + client.api.blueprints.list(name=...) # 私有列表 + client.api.blueprints.list_public(name=...) # 公开列表 + client.blueprint.create(name=..., dockerfile=..., build_context=BuildContext(object_id=...)) + client.blueprint.delete(blueprint_id) + ``` +- **特殊：构建上下文是独立托管对象** + + ```python + storage_object = await sdk.storage_object.upload_from_dir( + dir_path=Path, name=str, ttl=timedelta, # 上下文有自己的 TTL + ) -> StorageObject + ``` + Blueprint 创建请求引用 `BuildContext(object_id=storage_object.id, type="object")`，因此构建上下文与 Blueprint 解耦：上下文短命（TTL 1h 即可），Blueprint 永久。 +- **生命周期**：Blueprint **永久保留并持续计费**（官方文档明确提醒）；StorageObject 按 TTL 自动过期 +- **用户控制**： + - 缓存复用：按 `name` 查 list，取最新 `build_complete`；**无内容哈希**，同名同 dockerfile 改了内容也不会触发重建 + - 强制重建：调用 `blueprint.create()` 不复用旧 ID 即产生新 Blueprint + - 删除：`blueprint.delete()`（官方建议主动清理旧版本控制成本） + +--- + +### GKE — 用户自管 Artifact Registry + +- **产物类型**：标准 OCI/Docker 镜像（这是六个平台中唯一让用户拿到原生 Docker 镜像的） +- **存储位置**：**用户自有的** Google Artifact Registry，按 region 存储。Daytona/E2B/Modal/Runloop 都是平台托管，GKE 是用户托管 +- **管理 API**： + + ```bash + gcloud builds submit --tag /:latest # 构建并推送 + gcloud artifacts docker images describe # 检查存在 + gcloud artifacts docker images delete # 删除 + ``` + Repository 也支持 cleanup policy（按 tag 状态、版本数、镜像年龄自动清理） +- **生命周期**：用户完全自管,Cloud Build 缓存层由 GCP 自动管理 +- **用户控制**： + - 缓存复用:tag 固定为 `{environment_name}:latest`,**无内容哈希**,内容变化但 tag 不变会静默复用旧镜像 + - 强制重建：`force_build=True` 走 `gcloud builds submit` 覆盖 `:latest` + - 删除：CLI / Console / cleanup policy +- **费用**：用户 Artifact Registry 按 GB/月计费 + 跨 region 拉取的出网费用 + +--- + +### Docker — 本地 Docker daemon（无远端存储） + +- **产物类型**：标准 Docker 镜像 +- **存储位置**：**宿主机本地磁盘**(无 push 到 registry) +- **管理 API**：原生 Docker CLI + + ```bash + docker images # 列表 + docker rmi # 删除 + docker image prune # 清理悬挂镜像 + docker compose down --rmi all # 一并删除 compose 镜像 + ``` +- **生命周期**：持久存在直到显式 `docker rmi` 或 `docuum` 等清理工具 +- **用户控制**： + - 缓存复用：Docker daemon 自动按 layer cache,Dockerfile 指令或文件内容变化即触发对应层及其后所有层重建（**自动内容感知**） + - 进程内并发去重：Harbor 通过类级别 `_image_build_locks: dict[name, asyncio.Lock]` 串行化同名镜像的并发构建,跨进程不生效 + - 强制重建：`docker compose build --no-cache` + +--- + +## 对比 + +### 接口与缓存 + +| 平台 | 接口模式 | 缓存 key | 内容变更检测 | +|------|---------|---------|------------| +| Daytona | 热路径
