Dockerコンテナに環境変数を渡す

やりたいこと

コンテナにAWSのアクセスキーIDと秘密アクセスキーを渡したい

直接runするとき

docker run -e AWS_ACCESS_KEY_ID=xxxx -e AWS_SECRET_ACCESS_KEY=yyyy [tag]

composeファイルに書くとき

environment:
    - AWS_ACCESS_KEY_ID: xxxx
    - AWS_SECRET_ACCESS_KEY: yyyy

とかする

ファイルに埋めたくないとき

environment:
    - AWS_ACCESS_KEY_ID
    - AWS_SECRET_ACCESS_KEY

ってやっておくとホストの環境変数が参照されるようなのでこちらがベターでしょう。
