When starting up Envoy, it will log:

[2019-08-14 17:54:50.092][1][info][main] [source/server/server.cc:438] runtime: layers:
  - name: base
    static_layer:
      {}
  - name: admin
    admin_layer:
      {}
[2019-08-14 17:54:50.092][1][warning][runtime] [source/common/runtime/runtime_impl.cc:497] Skipping unsupported runtime layer: name: "base"
static_layer {
}

This is causing some confusion. What does this mean?

It seems like Envoy is trying to create some runtime layer "base" that it doesn't even support?

It seems to me, having no knowledge of runtime layers, that either

• Envoy shouldn't create this "base" layer
• Envoy should "support" this "base" layer
• Envoy should not warn about not supporting the base layer

Reproduce by running docker run --rm -p 10000:10000 envoyproxy/envoy-dev:e1d713efc1342790208a86b7ba795d692b47f443
