Is it possible to install a docker image direct from docker hub?

[eddowding]

..rather than download > build > push?

eg https://hub.docker.com/r/ctadeu/calendso and not https://github.com/calendso/docker

@eddowding running upstream docker images usually does not work, since Cloudron will put various bits of the filesystem into read-only mode for security and consistency reasons. So to have a reliable app instance, you would have to adjust the upstream Dockerfile and make sure all data ends up in either /app/data and/or the addon database Cloudron provides. Otherwise the backups and restore features will not work.

@nebulon ... but presumably pulling a built-for-cloudron app direct from docker hub would work to avoid the build / push steps ?

e.g. if I do a custom build for myself, but make my repo on docker hub available to others

yes, that definitely works. all the appstore app images are stored in docker hub as well.

[eddowding]

Interesting. So with that in mind, is there / could there be a 'community' list of images somewhere?

[timconsidine]

@eddowding By chance I discovered some custom apps I built were listed as public. Wasn't my intention but no problem. So I will find 2 or 3 ones I have done and share their links later. Just in case it saves someone some time or stress.

Not sure this the right place to post this, but it's kinda on topic, and don't know where else (tell me where or feel free to move it).
These are a couple of custom packages I built.
I take zero credit for them : they are the work of other talented people. I just built them.

Any dates in the 'tags' are the date I built them, not the the date of the underlying package. They may not be latest available

My understanding is they can be installed in your cloudron instance - without building / pushing first - by :
cloudron install --image <repo-name>:<tag-name>

(haven't got this configured yet, but it installs)

Thanks, TIm!

When I try this I get:

$ cloudron install --image tcmbp132021/paperless-ng:derek210709
> No CloudronManifest.json found

[timconsidine]

@eddowding errrr ...
I'll have to look into it, apologies

@eddowding I think you have to pull the git repo and do it from there. There has to be a CloudronManifest.json in the local directory when you do this.

[eddowding]

Thank you all.

I guess.. I think this is "all a bit complicated" to learn in the time available. I may revisit later, but for now I think some feedback / an output is that it would be useful to:

• be able to install just by giving a github repository
• provide a simple / guided Manifest creator form (with some best-guess defaults)

I appreciate that these things are easier said than done, and may for all I know be entirely impossible / wrong thing to ask for.
