AWS SDK または CLI PutObjectで使用する

オブジェクトをアップロードするには

次のput-object例では、指定されたコンテナにオブジェクトをアップロードします。オブジェクトがコンテナ内に保存されるフォルダパスを指定できます。フォルダがすでに存在する場合、 AWS Elemental MediaStore はオブジェクトをフォルダに保存します。フォルダが存在しない場合、サービスはフォルダを作成し、オブジェクトをフォルダに保存します。

aws mediastore-data put-object \
    --endpoint https://aaabbbcccdddee.data.mediastore.us-west-2.amazonaws.com \
    --body README.md \
    --path /folder_name/README.md \
    --cache-control "max-age=6, public" \
    --content-type binary/octet-stream
