tweeeetyのぶろぐ的めも

アウトプットが少なかったダメな自分をアウトプット<br>\(^o^)/

【GAE】appengine(app-engine-go)をhomebrew経由で入れたgo1.6.3 (appengine-1.9.48)から、cloud sdk経由で入れるgo version 1.8.5 (appengine-1.9.68) にupdateするメモ

はじめに

GAE goな環境を使っています。

結構長いことgo1.6.3 (appengine-1.9.48)で困った事はなかったのですが、
goのversionの関係でtestingパッケージのt.Run()が使えなかったりとあったのでupdateしました。

以前は、homebrew経由でinstallおよびアップデートができたのですが、
いまはサポートされておらずcloud sdk経由に変わったとの事です。

その時の自分メモ

gcloud以外のcommponentsを確認

ついで程度ですが、componensまわりを確認してみます

$ which gsutil
/Users/tweeeety/google-cloud-sdk/bin/gsutil

$ goapp version
go version go1.6.3 (appengine-1.9.48) darwin/amd64

# goappはhomebrewで入れた?か忘れたがCellarに入っていた
# 新しく入れる方は/usr/local/Caskroom配下になる予定
$ which goapp
/usr/local/bin/goapp

$ ls -al /usr/local/bin/goapp
lrwxr-xr-x  1 tweeeety  admin  43  1 11  2017 /usr/local/bin/goapp -> ../Cellar/app-engine-go-64/1.9.48/bin/goapp

2. google-cloud-sdkをUPDATE

まず、以前にgoogle-cloud-sdkbrew caskにて入れていたようなのでその辺の確認から行います。

gcloudの再インストール

# versionを確認
$ brew cask --version
Homebrew-Cask 1.6.1
caskroom/homebrew-cask (git revision 385494; last commit 2018-04-23)

# caskで入れたlistを確認
$ brew cask list
google-cloud-sdk
vagrant

# そのままinstallしてみるが
# re-installしてねと言われる...まぁそうだね
$ brew cask install google-cloud-sdk

Warning: Cask 'google-cloud-sdk' is already installed.

To re-install google-cloud-sdk, run:

# すなおにreinstall
$ brew cask reinstall google-cloud-sdk

最後にビールの絵とともにgoogle-cloud-sdk was successfully installed!と言われます

gcloudコマンドの初期化(ログイン)

公式を参考に行いました
* Cloud SDK の初期化

公式には以下のように記載されています

通常、Cloud SDK をインストールした後、gcloud init コマンドを実行して初期設定を行います。
後で gcloud init を実行して設定を変更したり、新しい設定を作成したりすることもできます。
 

  • Cloud SDK ツールを承認して、現在のユーザー アカウントの認証情報を使用して Google Cloud Platform にアクセスできるようにします。すでにアクセスが承認されている場合はアカウントを選択できます。
  • Cloud SDK 構成をセットアップし、一連の基本プロパティを設定します。たとえば、上記のステップで設定した有効なアカウント、現在のプロジェクト、Google Compute Engine のデフォルトのリージョンとゾーン(該当する場合)などです。
gcloud init

初回の場合は、gcloud initを打ってセットアップします。
自分は既にセットアップ済みの内容を変えたくなかったのでloginのみにしました。

# そのまま打つだけ
$ gcloud init

# この後いろいろ聞かれるので設定に合わせて答える
gcloud auth login

セットアプップ構成を変えたくなかったので、
ユーザー アカウントを使用して承認だけをおこないました

# ブラウザが起動して認証を行う
$ gcloud auth login

3. Components(app-engine-go)のインストール

goappコマンドが使いたいので
app-engine-goというComponentsをインストールします。

以前にbrewで入れたものとバッティングしてうまくいかなかった編

Componentsのインストール状況を確認

念のためインストール状況を確認します

$ gcloud components list

brewで入れた方を消す

最初から消せば良かったのですが、ここでようやく消します。

# brewで入れか確認
$ brew list | grep app-engine
app-engine-go-64

# appengine系のコマンドも、きっとbrew経由のままだろうな、を確認
$ ls -al /usr/local/bin/appcfg.py

# 一応unlinkだけしてみる
$ brew unlink app-engine-go-64

# 思い切ってremove

Remove all versions with `brew uninstall --force app-engine-go-64`.

# ↑でRemove allしてよね、と言われてるが再度確認
# やっぱりまだいる
$ brew list | grep app-engine-
app-engine-go-64

# 再度消す
$ brew remove app-engine-go-64
Uninstalling /usr/local/Cellar/app-engine-go-64/1.9.38... (6,634 files, 225.0MB)

# gcloudコマンドもhomeに置いたままなので、この辺も消す
$ which gcloud
/Users/tweeeety/google-cloud-sdk/bin/gcloud

# 消す(いったん移動...)
$ mv ~/google-cloud-sdk .google-cloud-sdk

# 再度確認すると、Caskroomの方に切り替わってくれた模様
$ which gcloud 
/usr/local/bin/gcloud

$ ls -al /usr/local/bin/gcloud

再度、app-engine-goをインストールでうまくいった編
