はじめに

gcloud コマンドで key を取得しようとした際、The Application Default Credentials are not available.と出た時の対処法についてまとめます。

原因と対処

default のkeyが読み込めていないことが濃厚です。
対処法としては、環境変数でgcp の key の場所を定義するだけでパスすることができます。

詳細

% curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \

`gcloud auth application-default print-access-token`  がうまく動いていないようですね。

gcloud auth application-default print-access-token

ERROR: (gcloud.auth.application-default.print-access-token) The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

環境変数 `GOOGLE_APPLICATION_CREDENTIALS` に gcp の key を登録します。

export GOOGLE_APPLICATION_CREDENTIALS=~/.ssh/gcp.json

 再度 `gcloud auth application-default print-access-token` を叩くとtoken を取得することができます。
