Hi Railway Team,

I hope you are doing well.

I am currently using Railway's Object Storage service and I have a few questions regarding file access and public URLs:

Note - Previously I was using cloudflare R2, I decided to switch to Newly launched S3 bucket on Railway platform, cloudflare R2 has custom domain option, does railway?

  1. How can I obtain a public URL for the files stored in my Object Storage bucket?
    At the moment, I am only able to access files using the internal S3-compatible API, but direct public access results in AccessDenied.

  2. Is there a way to enable public file access for a specific bucket or folder?
    For example, I want to make my uploaded media files publicly accessible via a URL.

  3. Does Railway support configuring a custom domain for object storage?
    I would like to serve my files from:
    media.qloto.net

  4. If custom domains are supported, could you please guide me through the setup process?
    I am specifically looking to understand:

Required DNS records

Any CNAME target or special endpoint

Whether SSL certificates are provided automatically

My goal is to allow users to access media files without needing signed URLs, using a clean and readable custom domain.

If possible, I would appreciate it if you could help me configure my storage to use:

https://media.qloto.net

Thank you for your assistance. Please let me know if you need any additional details from my side.

Best Regards,
Ritik Raj

IIRC custom URLs aren't supported for buckets just yet.
The public URL can be found in bucket > credentials tab.
If you're not able to access it, I would make sure bucket name, access keys (ID & secret) and endpoint URL are copied correctly.

public urls dont exist the same way with r2, you have to generate a presigned url

Mb misread.

I guess presigned urls are temporary and expire after sometime, i need permanent URL

Is there any solution available with the Railway S2 bucket?

https://railway.com/deploy/public-bucket-image-proxy this might work for you, but youll likely be incurring egress fees as its a proxy

https://railway.com/deploy/public-bucket-urls might also want to take a look at this, it says no egress incurred
