wasmo
A MAIF opensource project
Wasmo CLI brings WASM to your architecture
Wasmo CLI can be combined with the power of Docker Wasmo server images to build locally and remotely WASM binaries.
Installation
This project can be installed and compiled from source with this Cargo command:
$ cargo install wasmo
or
$ brew tap maif/wasmo
$ brew install wasmo
Additionally there are precompiled artifacts built on CI which are available for download as well.
Installation can be confirmed with:
$ wasmo --version
Subcommands can be explored with:
$ wasmo help
Core commands
The wasmo
CLI internally contains a number of subcommands for working
with wasm modules:
Tool | Arguments | Description |
---|---|---|
wasmo config set |
path | server | clientId | clientSecret | Globally configure the CLI with the path where the configuration file will be stored and the server to reach during the build. These parameters are optional and can be passed when running the build command. |
wasmo config get |
Get the configuration from the configured path file or from $HOME/.wasmo |
|
wasmo config reset |
Clean configuration and reset to default settings. The default file path configuration will be $HOME/.wasmo |
|
wasmo init |
template | name | path | Initialize a WASM plugin to the specific path. You can choose between many templates, javascript/typescript (js/ts), Open Policy Agent (opa), Rust or Golang (go). |
wasmo build |
path | host | server | clientId | clientSecret | Build the plugin by sending the contents to the remote or local Wasmo server. As soon as the build is complete, the WASM binary is donwloaded and saved in the plugin folder. |
Quick start
wasmo init --name=my-first-plugin --template=js
wasmo build --host=OneShotDocker --path=my-first-plugin
Then open the content of your my-first-plugin
folder. You should find the generated WASM binary named my-first-plugin-1.0.0.wasm
.
Selecting a template
You can now optionally start a new plugin from a template by appending --template=[template-name]
to the creation command.
If you don't pass a template, Wasmo will list the available templates: js
, ts
, opa
, go
and rust
.
wasmo init --name=my-first-plugin --template=[template-name] --path=[output-directory]
Running this command with any of theses templates will create a directory called my-first-plugin
inside the specified output directory (or the current if omitted). Inside that directory, it will generate the initial project structure with the metadata file pre-filled with the name of your plugin.
Creating a production WASM binary
wasmo build
starts the process to build a WASM binary of your plugin. Inside the plugin directory will be your WASM binary and sources.
You have two ways to build your plugin:
- locally with Docker
- remotely by deploying a Wasmo server
Assuming we want to build our my-first-plugin
locally. Enter wasmo build --host=OneShotDocker --path=my-first-plugin
to start the build.
Let's explain these 3 parameters:
- the
path
parameter is explicitly used to indicate the plugin to build - the
host
indicates which kind of Wasmo server used. The pratical way is to useDocker
orOneShotDocker
because it prevents to install a Wasmo server by deploying, inside your locally Docker, a new Wasmo container. The last possible value isRemote
and can be used to specify with a URI the remote Wasmo server used.
Configure your configuration file
wasmo config get
wasmo config reset
wasmo config set <key>=<value>
Note: This command is unaware of workspaces.
Description
wasmo gets its config from the command line, environment variables, .wasmo
files, and in some cases, directly from the build command.
The wasmo config
command can be used to update and edit the contents of the user and global wasmo files.
Sub-commands
set
wasmo config set <key>=<value>
Sets each of the config keys to the value provided.
If value is omitted, then it sets it to an empty string.
The available keys are:
path
: configure the path where the wasmo configuration will be storedserver
: the Wasmo server to build your plugins (an URL format value is expected)clientId
: the client id used in Basic and Otoroshi AuthclientSecret
: the client secret used in Basic and Otoroshi Auth
You can also edit the configuration file manually. In this case, the following values are :
path
= WASMO_PATHserver
= WASMO_SERVER
get
wasmo config get
Show all the config settings.
reset
wasmo config get
Reset the configuration file with the default settings. The custom user .wasmo
files will not be deleted.
