Is it possible to host Cloudron on a Jelastic-powered cloud like Hidora?

The tech here is from Jelastic.

@girish I have set JitsiMeet up to scale both vertically and horizontally; the search starts from tomorrow to find enough users to load it and actually make it scale!!! But I know people who have started with a similar small instance of Jisti and scaled it vertically - on demand - to 40+ users with great success. No need to start with a 4CPU/32GB RAM VPS to achieve this.

And here is another business using the same underlying Jelastic tech to offer Jitsi and BigBlueButton meetings - of varying sizes - by the hour! It follows logically!

There is a large overlap between the important Cloudron apps and their "easy-to-install, autoscaling" apps: Nextcloud, Gitlab, Mattermost, Jitsi, BigBlueButton, Redmine, WP, Ghost, etc

From these two screenshots, its clear they clearly scale WP very well:

@oj looks interesting, thanks. I think to run Cloudron on something like this though we'd need to find a provider who offers a Jelastic VPS with full Ubuntu that Cloudron could be installed on... Have you found any?

[girish]

I could be wrong but those look like PaaS templates (sort of like docker compose files or even the newer k8s helm templates). Installing things with lots of interconnected components only gets you 20% though. Someone has to understand what it installed, maintain this, have a backup system, periodically update this, apply patches etc. This is why I think they target devops and are selling infrastructure (as in, they are not selling "scalable wordpress").

Of course, if they do all that, then it's a very good solution for hosting scalable apps. At least with Cloudron, our goal is not to install jitsi for 500 users or wordpress for million hits per day. Those products have to be priced very differently and have very different solution/architecture as well.

@jdaviescoates I currently use MirHosting and you can create Ubuntu VPS from their Jelastic platform, so I am (almost) sure you can do the same with your current Jelastic provider.

@alejandrolengua Do you mean you are using it for a Cloudron install?

[alejandrolengua]

@scooke Today I spent almost 4 hours trying to install Cloudron but got several error messages.
If you want to see them you can check these Dropbox folder where I uploaded several screenshots

@alejandrolengua Hmmm. I guess it has Ubuntu 18 installed on that Jelastic?

[girish]

@alejandrolengua It seems that the installation process got stuck because some package required manual yes/no. Can you try this on a fresh Ubuntu 18.04:

apt update
apt upgrade

Then install cloudron. I am guessing that one of the commands below will ask you a blocking yes/no question.

[scooke]

@alejandrolengua Which service are you using at Mirhosting?

I'll be honest with you, that is one complicated looking Dashboard! I managed to figure out how to generate a plain old Ubuntu 18.04 environment, but on the free trial I can't have an IP4 address. So I will just continue and see how this goes.

Well, I was trying to install Cloudron on both Mirhosting, and Ultime Hosting (france), but both do not provide IP4 addresses for the free trials. And I don't really want to add funds to these either, sorry. But I can say that it is definitively getting stuck at

=> Installing software-properties-common

and tails tells me specifically:

Configuration file '/etc/resolvconf/resolv.conf.d/base'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** base (Y/I/N/O/D/Z) [default=N] ? Y

It just hangs here. EDIT: I spoke too soon, after about 20 minutes it resumed.

It seemed to fail again starting Docker.

storage_driver=$(docker info | grep "Storage Driver" | sed 's/.*: //')
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

I suspect that, according to the Dashboard, the environment I picked was Docker, and then I chose Ubuntu 18, whatever this jelastic is it already installed Docker in this service. Anyway, I ran systemctl start docker and systemctl daemon-reload, in one Terminal window, then reran the cloudron install script, and this time it resumed downloading all the various docker images. So, progress maybe?

EDIT: FINAL UPDATE
There was another fail, during the openjdk install. I wonder, I had to choose 8 "cloudlets" in order to get 1GB of ram for Cloudron, so I wonder if this is affecting the install. It doesn't sound like it is a physical instance, like a KVM VPS, so I suspect it is having trouble connecting everything and making it work. Maybe you should consider a plain old KVM? Good luck.
(The setup before openjdk was nginx, which completed, but there was a warning :

cat: /home/yellowtent/box/VERSION: No such file or directory

Jelastic seams to be a close source version of Harvester on steroid.

From what I understand, Jelastic and Harvester are kind of MetaOrchestror in the sense they can manage VM, Container, Docker Image/Swarm and Kubernetes Cluster.

So in a sense; it is possible to install Cloudron inside Jelastic, or Harvester, since these can emulate an Ubuntu VM inside a Container (introduced by Rancher years ago).

What Jelastic seams to bring on top of this MetaOrchestror Concept is few important points, that I would be please to see in Cloudron.

Jelastic provide a billing and fencing concept called pay what you use, let's do an example ::
Let's say we deploy Nextcloud for a client.

In Jelastic you will be able to reserve elastically resources (CPU, MEM, HD) such as having a minimum and a maximum which help you to figure how much it will cost you at the end of the month.

I mean Cloudron have something similar, but it is a little more abstract when it comes time to money.

Also Jelastic will lets you build bloc by bloc your application such as
Nextcloud is the application
but you could choose MariaDB or PostgreSQL as DB
and MemCache or Redis for caching
and add or not Varnish
and choose between Apache, Nginx or HaProxy

Where in Cloudron developers make that choice for you which obviously have PROS and CONS in both world.

So anyway, yes it is possible to run Cloudron inside Jelastic by deploying an Elastic-VPS with Ubuntu
