Using Object Storage for Cloudron Docker and Cloudron Backup?

I much prefer Cloudron putting everything an app needs into one image.

This is not advised because you will not need everything every time, which will use your space, increasing security issues, because, after all, it's harder to realize updates into a monolithic base image.

This is an example if a server was hosting just a single WordPress, if we can optimize the same cloudron base image, this is how many unused dependencies and packages are included that we don't use.

With just WordPress, we have to have the light base image + some debug tools + MySQL and the wordpress image itself that is base on apache + PHP (just the selected version that you are interested in) + wordpress core.

This will reduce by a reasonable amount of the space used by the cloudron base image.

And to conclude, I think that you can't store in an easy and reliable way images on an s3 server, because images are stored just once, even if you start multiple containers.

@MooCloud_Matt I like the diagram. Did you make it?
Also, isn't this exactly what Cloudron does though?

yes, I did =D

Nope, its not, cloudron includes everything, you always have:
Node 18.12.1
Go 1.19.3
Ruby 3.0
PHP 8.1
Python 3.10
Redis
Mysql
Mongo
pSQL

This for version 4.
If you want to keep compatibility with an older WordPress version because your plugin will not support 8.1.
you have to keep all it's included in cloudron base image v3

@MooCloud_Matt I didn't realize this! So my WP app, my Vaultwarden, Matrix, Mastodon, Github, Grav, Jellyfin, Navidrome, Nextcloud, Vikunja, Umami, OpenVPN, LAMP app, etc. has ALL of those in the image that is installed when I click Install X app in the app store?? Why are all of those needed? I have 52 apps installed... so each of those apps has ALL of that software in its image?? Wow.

I assumed that, for example with the LAMP app, that the image would include Apache, MySQL, and PHP. No node, no Go, no Ruby, etc. This is quite eye-opening.

@scooke
Not exactly; the image is stored once and used multiple times.
1 image multiple containers.
That means that you will not be impacted by a more optimized image because any way you use all its components.

But it will impact those who rent a 10 or 20 gb VPS because they will most likely use just part of that image, maybe just wordpres, or just a small nextcloud.
and they don't need ruby or node

You can if you attach remote storage via things like rclone.

[MooCloud_Matt]

@robi
yes, but then your image is used to run all your apps, which means that all those apps to run will have to get data from s3.

Remember that that image is not replicated anywhere else in the Filesystem, the container read their dependency from that file.
It would be like booting your server from s3, not a good idea, but that doesn't mean that storage footprint optimization is not possible in another way.

@MooCloud_Matt agreed, yet once it's loaded into RAM, there isn't much access to the filesystem at that layer. "Streaming" apps from S3 will have an impact on startup times and performance, but saves a lot of space.

A hybrid mode could be where long term layers are cached in RAM, short term offloaded remotely and essential app data kept locally which CL backups take care of.

On that, I don't have the data or experience to talk.
But 100% sure you can't use wasabi latency, I think smb or better NFS should be a better option, but I'm not an expert.
and Using so much ram for it, im not big fun about it, but I would have to try it before to have a real feedback
