I have been fiddling with trying to build a Dockerfile and container for the following.

A Alpine Linix image with LFTP, cron, & openssh installed for use with my external server to sync folders.

I have a Alpine Linix VM that I connect with a external server using SSH keys, and a cron task running a LFTP script on schedule.

Any help or pointing me at a container you know of is appreciated.

I currently have a alpine linix VM where I had one time SSH'd into the remote server to exchange logon keys.

This means I can run my scripts without username and login credentials I just need to point to a key file instead.

I might be overthinking it like you said.

Though essentially I am trying to build a docker image of this same setup and can see I will need llfp and cron. Just not sure how to handle the key file at this point.

What do you mean by handling the keyfile?

You can generate your ssh keys outside of docker and make them available in the container through a mounted directory. You will need to manually copy the public key to your remote host authorized_keys file anyway.

Ahh yes that's what I was looking to do.

I was thinking if I already have a key file on the remote and local servers then I may not need shh installed on the docker container to do this setup.
