如何利用 AWS Lambda 从 S3 读取文件并将其写入 AWS EFS

Question

I want to read a csv file from S3 and write it to AWS EFS using AWS Lambda. How can I achieve this? Please advice.

Answer 1

You can use ECS / Fargate to read a file from S3 and write to EFS. For your case, you can create a lambda to run ECS Task which would read from S3 and write to EFS and have that triggered by S3.

Using Lambda alone you can't use EFS because to use EFS you would need to mount as a device, hence you would need either ECS or EC2. As of April 8, 2020, ECS and Fargate support EFS generally available [Link] .
