wasmCloud

Wasm components linked at runtime (via wRPC) and running in wasmCloud.

Deploy locally

Setup

wasmCloud

Install wash with brew install wasmcloud/wasmcloud/wash.

wash --version
# wash          v0.38.0
# ├ nats-server v2.10.20
# ├ wadm        v0.19.0
# └ wasmcloud   v1.4.2

Docker

We use docker to start a local registry, so you will need to have it installed.

run

1. Start up a running environment.

   Starts:

   • a local redis server
   • a local postgres server
   • a local OCI registry
   • a single wasmCloud host, with NATS and wadm running
   • the wash UI (http://localhost:3030/)

   ./local/up.fish

2. Build (and sign) the components, pushing them to the local registry

   ./build_and_push.fish

3. Deploy the components with wadm

   ./start.fish

4. Redeploy the components with wadm

   ./restart.fish

5. Delete the application with wadm

   ./stop.fish

6. Stop the wasmCloud host

   ./local/down.fish

7. Test

   # create order (fish shell)
   curl localhost:8080/orders -d '
