Wasmer Edge Configuration

Wasmer Edge's configuration is stored in a app.yaml file in the root of your project.

Example

For a basic static site this file contains the following information:

kind: wasmer.io/App.v0
name: my-sample-site
description: A sample site for demonstration (optional)
package: wasmer/my-sample-site
 
# Specify environment variables
env:
  MY_VAR: "my-value123"

Fields

kind

The kind field is used to identify the type of configuration file. It is required and is a constant set to wasmer.io/App.v0.

name

The name field is used to identify the name of the application. It is required and must be unique.

• Required: true
• Required format: ^[a-z0-9]([-a-z0-9]*[a-z0-9])?$

The package field is used to specify the name of the package to deploy. It is required and must specify a package published to the Wasmer registry.

Note: if you have a wasmer.toml in the same directory as the app.yaml, wasmer deploy will automatically prompt you to publish a new version of the package.
