Cloudron Forum

@girish Thank you .. you've had a busy morning

@doodlemania2 That's a nice thing to do - helps a lot in the early days of a new instance

Thanks for looking into this and apologies for not following up - need to check my notification settings. (also work has been really busy so no mental energy for looking at my outside interests!)

I'm getting errors about the Java heap space fairly regularly (see sample below). They appear to take the Metabase app down. I had previously pushed the memory up on <my cloudron>/#/app/d00ef8b7-e3a6-43e3-8c3c-73d822c1fded/resources to 3GB but the container doesn't appear to hit that. A quick scan of Metabase docs seems to indicate there's an assumption the JVM will sensibly allocate memory but I'm wondering if it's not doing that under Docker operating conditions? I can't see an obvious way of passing in a Java option to explicitly set the heap size. Anyone else hit an issue like this? (I don't think I'm running anything too heavy in Metabase)

If there's nothing private in it; could you post your /etc/hosts file?

@mehdi I was thinking of nginx as the reverse proxy talking to the high ports. I have something similar in play for my docker containers at home with traefik: A request comes in for https://site.example.com (on 443) and it gets served from a docker container at 172.x.y.z:40000 or some high port number like that

@malvim What comes to mind for me is a reverse proxy - maybe you could get a cheap VPS and run nginx as a reverse proxy (or maybe Caddy). You can probably do it with AWS CloudFront as well

(Edit: I had suggested Cloudflare but when I double checked, I realised you can't set a port in their free products)

Yes, I'm effectively looking for a managed DB on the cheap (CouchDB may come onto my horizon too @atrilahiji - this is an area I'm getting into a bit more lately)

I'll definitely look at your suggestion @girish and I like your lines of thought @nebulon

Nice suggestion @marcusquinn but it's not quite what I'm looking for this time around.

I was having a look at some of the previous questions/discussions around using the mongodb instance that Cloudron itself makes use of. My take away understanding is that there's no intention to expose that instance to end-users. Which I can appreciate.

Having an instance I can access as an end-user came to mind recently. I've returned to my Cloudron instance with the intention of making better use of it: This has led to installing Metabase for a poke around and to access data I have in Atlas. In turn, I've then thought if I start to scale up my Atlas usage I need to start looking at cost and deciding if I should self-host mongodb. I can see why Cloudron wouldn't want to slot into the hosted DB type of role but interested in other folks views.

I'm wondering if there have been any thoughts after a year and a bit on how this has turned out? For example is $30 the right entry price point? (I'm grandfathered into $15 and wouldn't have joined at $30 fwiw). I'm genuinely curious as it's interesting from a startup pricing perspective.

When/If you get a chance I'd love to read more about what you have in mind for the docker addon. Seems like an area with a lot of potential.
