Runtime Operator

Development

You will need a local Kind cluster, NATS, and a Wash host.

For NATS, use:

docker run --rm --name wasmcloud-nats -p 4222:4222 nats -js

For Wash Host, use:

wash host --http-addr 127.0.0.1:8000

or from the top git directory:

cargo run -- host --http-addr 127.0.0.1:8000

For local kind cluster, refer to wash/README.md.

Install the CRDs into the cluster:

make install

Run the Builder / Watcher:

make devlog

You can apply development samples from the config/sample:

kubectl apply -f config/samples

Verify the Wash Host registered correctly with:

kubectl get host

Example:

❯ kubectl get host
NAME               HOSTID                                 HOSTGROUP   READY   AGE
exotic-toes-5866   14b0a1df-3f91-441c-b304-2aa56e9bef6e   default     True    52s

If you applied the samples, check if they deployed correctly:

❯ kubectl get workloaddeployment
NAME     REPLICAS   READY
blobby   1          True
hello    1          True

❯ curl -i hello.localhost.direct:8000
HTTP/1.1 200 OK
