Plenty of us are using Docker, Podman, Incus, chroot jails, etc to isolate services.
It has become good practice and it makes setting up yet another service, usually, so convenient.
Some services like YunoHost, StartOS, Cloudron and others try to facilitate the process.
What I haven’t seen though is a way to facilitate interoperability BETWEEN services we self-host. Sure there are plugins for each service, e.g. https://www.npmjs.com/package/peertube-plugin-livechat to provide XMPP chat for PeerTube, or anecdotal discussions e.g. https://github.com/jitsi/jitsi-meet/issues/7601 to embed PeerTube on Jitsi Meet.
So… how do YOU do it? How do you make on self-hosted service with another? Do you check after each one you install in the plugin category? Do you write your own plugins or extensions? Do you have a design pattern (e.g. Swagger API discovery with token generation per service, “cheat” via sockets, use a dedicate new service or even host) which you repeat?
I do ask because I bet most of you have a moment like this :
- Hey how about we start this new project together?
- Yes, let’s change the World!
- OK let’s write manifesto.md
- Where are we going to host it?
- Hmmm we could use my Cryptpad instance…
- OK but I don’t get notification on my GMail, could we use GoogleDocs instead?
So… I feel like FLOSS self-hosting is honestly on-par functionality-wise with proprietary solutions. I might be bias but it’s rare when I think “Damn… that’s cool, shame I can’t have it at home”. I can nearly always (in fact I have a hard time thinking of an example) self-host functional equivalent solutions myself. The ONE thing that I feel is often missing is integration which relies on interoperability.
How do YOU it?
PS: this isn’t about ntfy, PeerTube, HA or any specific service to a specific problem, it’s about HOW to facilitate, when one wants to, already great services work together.


Can’t say I’ve run into a need for such consideration yet. Excluding stacks explicitly meant to work together to some degree most of my services are an island to themselves and I like it that way. Then as far as notifications are concerned pretty much every supports at least email or ntfy.sh.
same
… well that’s the part I’m challenging. I was thinking like this but I’m wondering if that could be improved.
PS: I use ntfy and like it, that was just an example.
Do you have a specific use case for two containers that you want to talk to each other? There are some Docker containers that will cozy up, but as you point out, there are some that don’t. Maybe it would be worth the time to consult with the dev teams of said containers, and see if they have any suggestions or ways to go about it. It would seem to me that would be your best point to deviate from. Couldn’t hurt. I would create a defined road map of what you are trying to accomplish before hand, and run it by the dev teams. Just give them a little time to respond. They are real people with real lives too.
As I’m thinking about it, I wonder if your solution might be automation? Something like n8n might allow cross container exchanges. Of course, those data points have to be present for you to tap them tho.
Sure, for example once a Jitsi Meet meeting ends (more than 1 person in a room in, everybody gone), save the chat log to CopyParty e.g. WebDAV push to /meetingname_date.txt would be enough to be useful. It’s something we tend to do manually on a regular basis.
Yes no rush and I can code so I would be able to test before suggesting anything.
I don’t touch AI but I do think conventions, e.g. not “just” an API but SWAGGER, specific filesystem on mountpoints, etc could facilitate this.
