How do I enable TLS for Seaweedfs S3 API?

Question

My local development consists of a SPA, an ASP.NET Core backend with Seaweedfs S3 API to store some images uploaded from the client. At first I was using S3 with HTTP and it was temporarily okay, everything works perfectly without the need of TLS. But I was wondering if enabling TLS on my localhost was possible. And how would that work in a production environment.

I have tried 2 ways:

1. Created self signed CA certificate and signed a certificate for S3, and configured it like this inside my docker-compose:

version: '3.9'

services:
  master:
    image: chrislusf/seaweedfs:dev # use a remote dev image
    ports:
      - 9333:9333
      - 19333:19333
    command: "master -ip=master"
  volume:
    image: chrislusf/seaweedfs:dev # use a remote dev image
    ports:
      - 8080:8080
      - 18080:18080
    command: 'volume -mserver="master:9333" -port=8080 -ip=volume'
    depends_on:
      - master
  filer:
    image: chrislusf/seaweedfs:dev # use a remote dev image
    ports:
      - 8888:8888
      - 18888:18888
    command: 'filer -master="master:9333" -ip.bind=0.0.0.0'
    depends_on:
      - master
      - volume
  s3:
    image: chrislusf/seaweedfs:dev # use a remote dev image
    ports:
      - 8333:8333
    command: 's3 -filer="filer:8888" -ip.bind=0.0.0.0 -key.file=/etc/seaweed/server-key.pem -cert.file=/etc/seaweed/server-cert.pem'
    depends_on:
      - master
      - volume
      - filer
    volumes:
      - ./server-key.pem:/etc/seaweed/server-key.pem
      - ./server-cert.pem:/etc/seaweed/server-cert.pem
      - ./ca.pem:/etc/seaweed/ca.pem

but the logs when I try to access the port through HTTPS:

2. put a reverse proxy (YARP in this case) before the S3 to handle TLS termination, the GET request works fine, but if I call method AmazonS3Util.DoesS3BucketExistV2Async in .NET it returns a 403 saying the signature is wrong, meanwhile if I turn off HTTPS it works. I think that this is more of an S3/Seaweed problem than TLS.

any idea how do you guys do it in the real world? I may need to be enlightened on TLS/SSL so any help would be appreciated.

Answer 1

Per https://github.com/seaweedfs/seaweedfs/discussions/5345#discussioncomment-8606445

there 3 options are required:

-s3.port.https=8334 -s3.cert.file=/etc/seaweedfs/certs/s3.crt -s3.key.file=/etc/seaweedfs/certs/s3.key
