# wacker
Like Docker, but for WASM.
## Installation
You can download binaries directly from the [Releases](https://github.com/wacker-dev/wacker/releases) page.
Or you can install it using `cargo`:
```
cargo install wacker-daemon
cargo install wacker-cli
```
## Getting started
Start the wacker daemon:
```
$ wackerd
[2023-11-22 07:25:31 INFO wackerd] server listening on "/Users/user/.wacker/wacker.sock"
```
Run a WebAssembly program:
```
$ wacker run hello.wasm
$ wacker run time.wasm
```
Where [hello.wasm](https://github.com/wacker-dev/wasi-examples/tree/main/hello) is a simple WASM program that prints out `Hello, world!` and exits, and [time.wasm](https://github.com/wacker-dev/wasi-examples/tree/main/time) is a long-running program that constantly prints out the current time.
> You can find more WASI program examples at https://github.com/wacker-dev/wasi-examples.
Serve an [HTTP WebAssembly program](https://github.com/wacker-dev/wasi-examples/tree/main/http):
```
$ wacker serve hello_wasi_http.wasm --addr 127.0.0.1:8081
```
The path can be a local file path or a URL, eg:
```
$ wacker run https://raw.githubusercontent.com/wacker-dev/wacker/main/wacker/tests/wasm/hello.wasm
```
List running programs:
```
$ 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
```
Fetch the logs:
```
$ wacker logs hello-w0AqXnf
Hello, world!
$ wacker logs -f --tail 5 time-xhQVmjU
current time: 2023-11-22 07:42:34
current time: 2023-11-22 07:42:35
current time: 2023-11-22 07:42:36
current time: 2023-11-22 07:42:37
current time: 2023-11-22 07:42:38
```
And you can also stop/restart/delete the program:
```
$ wacker stop time-xhQVmjU
$ wacker restart time-xhQVmjU
$ wacker delete/rm time-xhQVmjU
```
