Running in a container

For convenience we have published a container image that contains Wasm Workers Server. It is available at ghcr.io/vmware-labs/wws:latest. Any container that runs it will get the wws binary, running and:

  • Looking for workers in the /app folder
  • Listening on 0.0.0.0:8080 inside the container

The image is built from scratch. It only includes the wws binary. The container supports multiple architectures: linux/amd64 and linux/arm64 platforms. The image size is just 27MiB.

Running a local container​

A typical one-liner to run a local container for development purposes would look like:

docker run -v /path/to/workers/on/host:/app -p 8080:8080 \
 ghcr.io/vmware-labs/wws:latest

Other usages​

Wasm Workers Server is stateless as far as the loaded handers are stateless (i.e. when they don't use the Key / Value store). This makes the image very useful if you want to setup your own auto-scaling deployment.
