gcloudでprojectを簡単にswitchする方法

需要があるならちゃんとしてGolangで作ります

1.追加したいプロジェクトの箱を作成する

$ gcloud config configurations create oreno-project-dev
Created [oreno-project-dev].
Activated [oreno-project-dev].

2.プロジェクトの設定を行う

$ gcloud config set compute/region us-central1
$ gcloud config set compute/zone us-central1-a
$ gcloud config set core/account [e-mail]
$ gcloud config set core/project oreno-project-dev

$ gcloud config list
[compute]
region = us-central1
zone = us-central1-a
[core]
account = [e-mail]
disable_usage_reporting = False
project = oreno-project-dev

Your active configuration is: [oreno-project-dev]

3. 切り替え用スクリプトを .bashrc or .zshrc に登録する

cat <<'EOF' >> ~/.bashrc

# gcloud profile switcher
function gx () {
  if test $# -eq 0; then
    gcloud config configurations list
  else
    gcloud config configurations activate $1
  fi
}
EOF

source ~/.bashrc

4.切り替えてみる

$ gx list
NAME                IS_ACTIVE  ACCOUNT                     PROJECT             DEFAULT_ZONE       DEFAULT_REGION
oreno-project-dev  True       [e-mail]  oreno-project-dev  us-central1-a      us-central1
default             False      [e-mail]  oreno-project      asia-northeast1-a  asia-northeast1

$ gx default
Activated [default].

$ gx list
NAME                IS_ACTIVE  ACCOUNT                     PROJECT             DEFAULT_ZONE       DEFAULT_REGION
oreno-project-dev  False      [e-mail]  oreno-project-dev  us-central1-a      us-central1
default             True       [e-mail]  oreno-project      asia-northeast1-a  asia-northeast1
