Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.

Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

I get LFTP and somewhat cron, but why OpenSSH? You can also SSH to the host and get into the container from there.
ITry to keep containers minimal, meaning only add what you absolutely need. Also I advise you to keep/consider the content of the container as immutable. If something's wrong, throw it away and restart with aa clean container. Data that you download should reside on a volume mapped to the container and this can usually also be accessed from the host. Same for any LFTP/cron config, etc.
So, what exactly is you plan why you need to SSH into the container itself? This post smells a bit like a XY Problem.
A quick google reveals that there are ready to go docker images with LFTP (which weighs about 7.5MB), which might be completely suitable for your need depending on your use case? https://hub.docker.com/r/minidocks/lftp/
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_keysfile 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.
I'd never heard of the XY Problem before.
I get it - big opportunity to waste lots of time.
However, while I've never posted a question on stack overflow or similar, a common complaint is that it's a toxic community because of responses related to this problem - a user asks about X and is accused of asking about Y and most responses undermine the premise being question Z.
