Wacker

类似于Docker，但针对WASM。

安装

您可以直接从发布页面下载二进制文件。

或者，您可以使用cargo安装它

cargo install wacker-daemon
cargo install wacker-cli

入门

启动wacker守护进程

$ wackerd
[2023-11-22 07:25:31 INFO wackerd] server listening on "/Users/user/.wacker/wacker.sock"

运行WebAssembly程序

$ wacker run hello.wasm
$ wacker run time.wasm

其中 hello.wasm 是一个简单的WASM程序，打印出Hello, world!并退出，而 time.wasm 是一个长时间运行的程序，不断打印当前时间。

您可以在https://github.com/wacker-dev/wasi-examples找到更多WASI程序示例。

提供HTTP WebAssembly程序

$ wacker serve hello_wasi_http.wasm --addr 127.0.0.1:8081

路径可以是本地文件路径或URL，例如

$ wacker run https://raw.githubusercontent.com/wacker-dev/wacker/main/wacker/tests/wasm/hello.wasm

列出运行中的程序

$ wacker list
ID                        PATH                   STATUS     ADDRESS
hello-w0AqXnf             hello.wasm             Finished
time-xhQVmjU              time.wasm              Running
hello_wasi_http-luf1vz6   hello_wasi_http.wasm   Running    127.0.0.1:8081

获取日志

$ wacker logs hello-w0AqXnf
Hello, world!

$ wacker logs -f --tail 5 time-xhQVmjU
