Hi,

I’m looking for a way to upload artifacts **directly to S3** , without passing through the Mender API.  
Anyone knows if this is possible? I tried uploading an artifact directly to minio, and obviously it didn’t show up in `artifacts list`. I suppose that there’s additional metadata required and it is stored in mongodb?

My use case:  
I got multiple Google Kubernetes clusters, and each cluster hosts its own Mender Server.  
I also have a build system that builds `mender artifacts` which need to be uploaded to all (or some of) the Mender Servers.  
I was thinking that if the build system could just upload the artifact directly to S3, I could use a single Minio which will serve all Mender Servers across all of my GKE clusters.

Unfortunately, I cannot use just a single Mender Server deployment for all my GKE clusters.  
Any suggestions/ideas are welcome.

I’m using v3.4.0

Thanks,  
Roman

Unfortunately, there currently is no way of uploading/registering artifacts without going through the Mender server. The backend needs to validate the artifact format and the payload and header checksums. The only reliable way I can think of is uploading the artifact to all your server instances.
