Google Well Known Types
They are embedded in the image and are included by protoc automatically.
They accessible via google/protobuf/:
syntax = "proto3";
import "google/protobuf/timestamp.proto";
import "google/protobuf/duration.proto";Gogo
gogo.proto is embedded in the image and can be included with:
syntax = "proto3";
import "github.com/gogo/protobuf/gogoproto/gogo.proto";Image Size
The current image is about ~130mb and one layer. Most the space is spent on Go tools. All the binaries are UPX'ed. Including the Swift stdlib.
