Your project default Compute Engine zone has been set to [{作成したタイムゾーン}].
You can change it by running [gcloud config set compute/zone NAME].

Your project default Compute Engine region has been set to [{作成したタイムゾーン}].
You can change it by running [gcloud config set compute/region NAME].

Created a default .boto configuration file at [{保存先}]. See this file and
[https://cloud.google.com/storage/docs/gsutil/commands/config] for more
information about configuring Google Cloud Storage.
Your Google Cloud SDK is configured and ready to use!

* Commands that require authentication will use {作成済みアカウント} by default
* Commands will reference project `{作成済みProject}` by default
* Compute Engine commands will use region `{作成したタイムゾーン}` by default
* Compute Engine commands will use zone `{作成したタイムゾーン}` by default

Run `gcloud help config` to learn how to change individual settings

This gcloud configuration is called [default]. You can create additional configurations if you work with multiple accounts and/or projects.
Run `gcloud topic configurations` to learn more.

Some things to try next:

* Run `gcloud --help` to see the Cloud Platform services you can interact with. And run `gcloud help COMMAND` to get help on any gcloud command.
* Run `gcloud topic -h` to learn about advanced features of the SDK like arg files and output formatting

認証が完了すると下記コマンドにて認証情報が確認できる

$ gcloud auth list
    Credentialed Accounts
ACTIVE  ACCOUNT
*        {作成済みアカウント}

To set the active account, run:
    $ gcloud config set account `ACCOUNT`

SSH接続

初回のみ下記コマンドで鍵を生成する

$ ssh-keygen -t rsa -C "{作成済みアカウント}"
Generating public/private rsa key pair.
Enter file in which to save the key ({HOME}.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in {HOME}.ssh/id_rsa.
Your public key has been saved in {HOME}.ssh/id_rsa.pub

GCEのVMインスタンス詳細画面→SSHキー→項目の追加を選択し、
先ほど生成したpublickeyの内容を設定する

スクリーンショット 2018-10-07 17.37.35.png

上記の手順が全て完了したら、下記コマンドからSSHログインを行う

$ ssh -i ~/.ssh/id_rsa {作成済みアカウント}@{作成済みインスタンスの外部IP}

感想

インスタンス作成〜SSHログインまで10分少々で出来ちゃいます:joy:
無料期間もあるので是非利用してみてください!
