Edgee

Edgee

The full-stack edge platform for your edge-oriented applications.

Edgee Docker Edgee Docs

⚠️ Edgee OSS Edition (v0.4.X) is in Development

Edgee OSS is currently in version 0.4.X and is considered unstable as we continue to enhance and refine the platform. We're actively working towards a stable v1.0.0 release, which will be available in the coming months.

We welcome feedback and contributions during this development phase, and appreciate your patience as we work hard to bring you a robust edge computing solution.

Documentation

Contacts

Check out the official docs to dive into Edgee's main concepts and architecture.

Running Edgee

Once you have a valid configuration file (see next section), you can run Edgee in different ways, using the installer, Docker or running as a Rust crate.

⚠️ Note: all the examples below assume that TLS certificates and WebAssembly components can be found in /var/edgee/cert and /var/edgee/wasm respectively. Feel free to use /local/cert and /local/wasm for local development.

Using the installer

You can install and run edgee locally using the installer script:

$ curl https://install.edgee.cloud | sh
[...]
$ ./edgee

Using docker

You can run it using the CLI:

docker run \
  -v $PWD/edgee.toml:/app/edgee.toml \
  -v $PWD/cert:/var/edgee/cert \
  -v $PWD/wasm:/var/edgee/wasm \
  -p80:80 \
  -p443:443 \
  edgeecloud/edgee

Or as part of a docker-compose.yml:

service:
  edgee:
    image: edgeecloud/edgee
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "./edgee.toml:/app/edgee.toml"
      - "./cert:/var/edgee/cert"
      - "./wasm:/var/edgee/wasm"

Building from source

Edgee is built in Rust and can be installed using Cargo:

cargo build --release

Then you can run it:

cargo run --release

Configuration

Edgee proxy is customized through the edgee.toml file (or edgee.yaml), which is expected in the same directory where edgee is running from.

You can get started by coping the existing edgee.sample.toml file:

cp edgee.sample.toml edgee.toml

Here's a minimal configuration sample that sets Edgee to work as a regular reverse proxy. Later we'll see how to enable edge components.

# edgee.toml
[log]
level = "info"

[http]
address = "0.0.0.0:80"
force_https = true

[https]
address = "0.0.0.0:443"
cert = "/var/edgee/cert/server.pem"
key = "/var/edgee/cert/edgee.key"

[[routing]]
domain = "demo.edgee.dev"

[[routing.backends]]
name = "demo"
default = true
address = "192.168.0.10"
enable_ssl = true

Log levels

Edgee allows you to control the granularity of logs you want to be displayed. The possible values are: trace, debug, info, warn, error, and fatal. This setting defines the minimal level to be displayed, so setting it to warn will show warn, error, and fatal messages while hidding the others.

Routing

The example above sets up one backend called "demo". As the default backend, it will receive all traffic directed to demo.edgee.dev. Additionaly, projects can have a number of backends and use routing rules to distribute traffic among them.

For example, we could add a second backend called "api" to handle all requests to demo.edgee.dev/api:

# edgee.toml
[[routing.rules]]
path_prefix = "/api/"
backend = "api"

[[routing.backends]]
name = "api"
enable_ssl = true
address = "192.168.0.30"

The supported matchers are:

  • path: the path matches exactly the provided value
  • path_prefix: the path starts with the provided value
  • path_regexp: the path matches the provided regexp

In addition to proxying the request, you could also rewrite the path:

# edgee.toml

[[routing.rules]]
path_prefix = "/api/"
rewrite = "/v1/"
backend = "api"

This way, calling /api/test on port 80 will result in calling /v1/test on the API backend.

Integrating with edgee components

Check out the official components docs to dive into the components architecture.

The Edgee proxy is designed for performance and extensibility, so you can easily integrate open source components based on the platforms you need. Here's a list of the components we've built so far:

You just need point to the WebAssembly implementation in your proxy configuration. You may also build your own components for integrations we don't provide yet.

Example

Let's see how to implement data collection using the amplitude component.

You simply need to add a new session to your configuration pointing to the WebAssembly component that implements the data collection protocol:

# edgee.toml
[[components.data_collection]]
name = "amplitude"
component = "/var/edgee/wasm/amplitude.wasm"
credentials.amplitude_api_key = "YOUR-API-KEY"

Debugging a component

You can enable debug logs for a specific component by setting the debug flag to true:

./edgee --debug-component amplitude
