Use a public dns provider. Cloudflare, route53, dyndns (are they still around?), etc. Cheap, reliable, no worries about joining a ddos by accident. Some services are better left to experts until you really know what you’re doing.
And if you do really know what you’re doing you’ll use a dns provider rather than host your own.
FWIW I manage docker compose files with ansible. Allows me to centrally manage them without the need to go logging into multiple vms. I also create a systemd service file to start/stop the containers (also managed with ansible).
That said I’m starting to switch over to k8s as well (also with microk8s which has been the easiest to work with). Definitely overkill but I want to learn it.
I think you need to learn more about how databases work. They don’t typically reclaim deleted space automatically for performance reasons. Databases like to write to a single large file they can then index into. Re-writing those files is expensive so left to the DBA (you) to determine when it should be done.
And how are you backing up the database? Just backing up /var/lib/postgres? Or are you doing a pg_dump? If the former then it’s possible your backups won’t be coherent if you haven’t stopped your database and it will contain that full history of deleted stuff. pg_dump would give you just the current data in a way that will apply properly to a new database should you need to restore
You can also consider your backup retention policy. How many backups do you need for how long?
We’re getting well away from the topic now. It depends on what you mean by “replace”. Railways and canals exist side-by-side as different solutions to similar problems - sure. And some railways have replaced some canals. But the panama canal will not be replaced by a railroad for example. It couldn’t do the same job. The pros/cons of each option depends on many factors.
The analogy is poor for comparing software. Linux distros will likely replace X11 with Wayland over time. To do the same thing that X11 was doing. It will be replaced “in place”. The very same thing you were using with X11 will now need to work on Wayland. This would be like running your barges on the railroad? Maybe? Depending on how you squint?
I wouldn’t expect my barge to work on the railroad. I do expect that Firefox will run on Wayland after having used it on X11 for 20 years.
I didn’t say there was a problem. I’m saying it’s pretty disingenuous to act like Wayland isn’t intended as a replacement for X11. All of which you seem to agree with. As you say “nobody forces Wayland onto anyone yet” (emphasis mine).
Also - I just love how your comment is written like a politician would have written it. “Sure you can use the dirty old X11 if you really want to, or you can use the nice new God-fearing Wayland”.
Yes. And it’s a bad analogy. Nobody is expecting you to be able to take a barge on railways. But existing linux applications are being expected to run on Wayland. As I said - railways didn’t replace canals - they’re different types of things.
