(https://qiita.com/ynozue/items/1564f957b6a644b24d62)で作成した、[ソースコード](https://github.com/ynozue/hello-gae-go/tree/echo)を元に利用している、golang の バージョンを v1.8 から v1.9 にバージョンアップする。
まずは、Cloud SDK のバージョンアップから開始する。
Cloud SDK のバージョンを確認

全てのコンポーネントが最新の状態にアップデートされていることを確認
ソースコードを修正
GAE の仕様が変わって、「application」「version」は削除しないとdeployできないので削除
gae_echo/app-engine.yaml
runtime: go
api_version: go1.9 // ← go1.8 から go1.9 に変更
handlers:
- url: /.*
script: _go_app
動作確認

WARNING 2018-08-21 00:10:39,055 devappserver2.py:124] *** Notice ***
In a few weeks dev_appserver will default to using the Cloud Datastore Emulator. We strongly recommend you to enable this change earlier.
To opt-in, run dev_appserver with the flag --support_datastore_emulator=True
Read the documentation: https://cloud.google.com/appengine/docs/standard/python/tools/migrate-cloud-datastore-emulator

でも、GAE にアップロードできなくなってる
ほんと意味ない。。。
次回その記事について記載します。
このブログによると V2 から V3 へバージョンアップされたからっぽいですね。
とりあえず、他の Web フレームワークを利用して試して見ます。
