SFTPGo on Fly.io - "/go.mod" not found: not found

[gnaffle]

I wanted to setup this sftpgo server on fly.io but face some issues.
I setup my account, created an app and used following docker file.

drakkan/sftpgo/blob/main/Dockerfile

Problem that I am facing now is that it does not want to build (I use the remote build machine)

Not really sure what I am doing wrong here?

Two questions:

1. Are you using Visual Studio?
2. What’s your .dockerignore look like?

I’m able to deploy this with no issue, if you’re using VS this may be your solution.

No just using the cmd line on Mac.
I am not using a .dockerignore

[gnaffle]

Seems I did something wrong with my dockerfile. If I use the dockerhub image all is working well!

@gnaffle

Would you mind sharing your Dockerfile? I’m setting up sftpgo now as well

[gnaffle]

@mhostetler I just started it with a simple docker command and slightly edited the toml file.
so the ports were correctly mapped

I used the only docker image

docker pull drakkan/sfpgo

Hope that helps?
