Switches for resource constrained VPS?

Installation
1

I don’t want a swap. I will risk OOM. Are there command line switches implied here to constrain RAM under 2gigs?

This instance will have at most 10 users. That’s right. TEN. Likely a frequent THREE users.

  • The default of 1 GB RAM works fine for small Discourse communities. We recommend 2 GB RAM for larger communities.

So I provisioned a non-refundable 1c2r. That’s it. No upgrades. Swap takes too much space. So pass.

You probably can’t build a container without swap. You could try creating the swap, building the container, shutting down the container, and removing the swap.

Swap had been a requirement for almost ten years.

You’re really on your own with this. I would advise highly against trying to circumvent the SWAP requirement. You should contact your cloud provider to provision a larger disk for you.

I tried the next best thing with two SSH windows. create swap, run launcher, other ssh window delete swap, launcher continued. And this might work on a better provisioned VPS. On my next spare I will try it. I have an instance now running on 4c12r

Given: cannot increase resources

Suggestion: increase resources

Typically you need more memory (RAM+swap) for an update than you do for normal service.

If you have no space for swap, it’s because your forum data (database+uploads) is using the space you need.

It’s just possible that you could follow the strategy

  • never update

or the strategy

  • migrate your data each time to a fresh up to date installation

But I’ve done my own struggling with a minimal sized instance, using my many decades of sysadmin experience. Eventually, it was preferable to use a bigger machine. In fact, very preferable, because the bigger machine was cheaper. This is because different providers charge different amounts - I moved from Digital Ocean to Hetzner.

The other possibility, which would require a bunch of work, would be to build the new image on another machine, put it to some repo, and then launch it on the low-resource machine.

But that’s beyond the kind of help it’s feasible to provide on a forum.

I guess the key takeaway was

and not

which was merely a suggestion to a path forward.
