envoy-1.yaml

static_resources:
  listeners:
  - name: listener_0
    address:
      socket_address:
        address: 0.0.0.0
        port_value: 10000    
    filter_chains:
    - filters:
      - name: envoy.filters.network.http_connection_manager
        typed_config:
          "@type": type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager
          stat_prefix: edge
          http_filters:
          - name: envoy.filters.http.router
          route_config: {}

the http_filter needs type config as envoyproxy/envoy#21464

    filter_chains:
    - filters:
      - name: envoy.filters.network.http_connection_manager
        typed_config:
          "@type": type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager
          stat_prefix: edge
          http_filters:
          - name: envoy.filters.http.router
            typed_config:
              "@type": type.googleapis.com/envoy.extensions.filters.http.router.v3.Router
          route_config: {}

Hi @peterj
This gist is used at https://tetrate.io/blog/get-started-with-envoy-in-5-minutes/# and without typed_config, it fails to work with Envoy v1.28.0
Appreciate if you can update the gist so it will reflect correctly on the blog as well.
