This repo contains the tooling that allows you to build and push WASM envoy filters, so they will be accessible to gloo.
To do so, first build the tool
go build .
The build the example filter (mostly copied from the envoy-wasm):
(cd example; bazel build :filter.wasm :filter_proto)
Push:
./wasme push gcr.io/solo-public/example-filter:v1 example/bazel-bin/filter.wasm example/bazel-bin/filter_proto-descriptor-set.proto.bin
load in to gloo:
kubectl edit -n gloo-system gateways.gateway.solo.io.v2 gateway-proxy-v2
set the httpGateway field like so:
