I added a dockerhub image to the the Container Registry. Then, succesfully ran the image in Cloud Run. The image is https://hub.docker.com/r/atmoz/sftp. The thing is I'm unable to access the sftp server from FileZilla client.
Any thoughts on what could be going on? Any alternatives? I've considered running the image in a Compute Engine container so that I can actually generate a private key to use it to connect from the FileZilla client. Would appreciate to hear from your wisdom.
