# Wasmeld Console
|
|||
|
|
|
|||
|
|
`wasmeld-console` 是 `wasmeld-runtime` 的本地 HTTP 管理适配器。它负责：
|
|||
|
|
|
|||
|
|
- 接收 `.wasmpkg`，校验并保存 `component.wasm` 与运行时 manifest
|
|||
|
|
- 发布、查询和下载不可变的二进制 WIT Package
|
|||
|
|
- 启动、停止和重启内嵌的 `wasmeld-runtime`
|
|||
|
|
- 启动、停止和重启常驻 Actor
|
|||
|
|
- 转发二进制调用
|
|||
|
|
- 暴露调用计数、状态和最近事件
|
|||
|
|
|
|||
|
|
Wasm 制品保存在本地文件系统。服务 manifest、调用计数和最近 256 条事件通过
|
|||
|
|
[Toasty](https://github.com/tokio-rs/toasty) 写入本地 libSQL 数据库，默认路径是
|
|||
|
|
`var/wasmeld/console.db`。
|
|||
|
|
|
|||
|
|
`wasmeld-console` 启动时会在同一进程内创建 `wasmeld-runtime`、加载 Wasmtime Engine，
|
|||
|
|
并重新注册已保存的 Component。Runtime 停止后 Console HTTP 和数据库仍然在线；
|
|||
|
|
再次启动 Runtime 会重新注册 Component，但 Actor 内存不做快照，服务运行状态统一
|
|||
|
|
恢复为 `stopped`。
|
|||
|
|
|
|||
|
|
## 启动
|
|||
|
|
|
|||
|
|
`wasmeld-console` 需要 Rust 1.95 或更高版本；Wasm 组件继续使用项目约定的 Rust 1.90
|
|||
|
|
工具链构建。
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
cargo +stable run -p wasmeld-console
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
默认监听 `127.0.0.1:8080`。
|
|||
|
|
|
|||
|
|
可用环境变量：
|
|||
|
|
|
|||
|
|
- `WASMELD_ADDR`
|
|||
|
|
- `WASMELD_ARTIFACT_DIR`
|
|||
|
|
- `WASMELD_DATABASE_PATH`
|
|||
|
|
- `WASMELD_WIT_REGISTRY_DIR`
|
|||
|
|
- `WASMELD_ALLOWED_ORIGINS`，多个 Origin 使用逗号分隔
|
|||
|
|
- `RUST_LOG`
|
|||
|
|
|
|||
|
|
