Galacteek on Cloudron

[LoudLemur]

@micmc The maintainer, @cipres, has a channel on LBRY and intends to start uploading some short, explainer videos on how to use some of Galacteek's many useful functions.

@cipres I am not sure specifically, but there are some tips about reducing the number of layers, using a smaller base image size (Alpine) and a dockerignore file might help:

It is great you are here, @cipres ! Please give this amazing developer a big welcome, Cloudron!

@micmc : me too +1
IPFS is interesting but my knowledge needs improving.
Getting hands on is good for that

Welcome @cipres !

dapps is so cool! I am an ex-Qt developer, btw. I wrote among other things Qt style sheets, QCompleter, QLabel etc Good to see QML going strong -

[cipres]

@girish Thank you ! Cool, 2011 talk, i'll watch it.

Yeah i think writing dapps in QML has some potential (or it could be a complete dead-end :D), i wrote the necessary interfaces so that from the QML code you can use IPFS functions like pubsub, to broadcast messages efficiently to all the peers. Also it integrates with QtWebEngine so you can load a JS-based ipfs page from your dapp ..

Most people working with ipfs write dapps in NodeJS, it's the classic approach. Ideally we could mix both ... but QML won't let you do async so i write the complex code in python and call that from the QML side.

@girish Qt is so beautiful!

Indeed!

Some documentation on how to use SparQL and IPFS from a QML dapp

New shapshots and docker image. Now when you search for things on the dweb it's automatically cached as RDF so it's way faster to lookup things later on even being offline.

There's also a bash script now to run the latest AppImage snapshot automatically:

curl -L https://galacteek.gitlab.io/galacteek-snapshot-install.sh | bash

[LoudLemur]

@cipres Thank you!

I hope that Galacteek can be packaged for Cloudron. You have kindly created a fresh Docker. Perhaps somebody will now volunteer to package it.

[cipres]

@LoudLemur Managed to get the Docker image down to ~820Mb, based on python:3.7-slim. It can be reduced even more but not that much, i'm surprised by the space the xorg packages take on a debian ...

[LoudLemur]

@cipres Well done! Could somebody take a crack at putting this on Cloudron?

[cipres]

@LoudLemur I've read the packaging tutorial, i can write and publish the CloudronManifest.json file in the galacteek repo if that helps. It seems that the docker image url/ref is not specified in the manifest but rather that you need to pass it when you run "cloudron install --image ..." ?

[timconsidine]

@cipres
Yes you need :

• CloudronManifest.json ( can be simple )
• Dockerfile
• source code

Then :

• docker build -t <reponame>/<appname>:<tag> .
• docker push <reponame>/<appname>:<tag>
• cloudron install --image <reponame>/<appname>:<tag>

[cipres]

@timconsidine Thank you ! The docker image is already automatically built from gitlab ci and pushed to gitlab's container registry here:

registry.gitlab.com/galacteek/galacteek:pimp-my-dweb-latest-x11vnc

So apart from the manifest there isn't much else that needs to be done it seems ?

[timconsidine]

@cipres generally nothing else needed BUT I think the Dockerfile may need to be custom to Cloudron. Depends on how complex the Dockerfile is.

• Generally advised to use latest base build
  FROM cloudron/base:3.2.0@sha256:ba1d566164a67c266782545ea9809dc611c4152e27686fd14060332dd88263ea
  Although I am not entirely sure about whether this is essential.

• May need to consider passing some Cloudron-specific variables for DB connection etc.

• Generally Cloudron deployments are 'static' in terms of system code under /app/code and changeable config and data under /app/data. But again not sure if this is essential.

Someone with more technical knowledge and better packaging experience may be able to explain / advise better than me.

[cipres]

@timconsidine Thanks a lot for your help.The Dockerfile is pretty simple. I don't want to have to maintain 2 different docker images.

Given that the password to access the UI via VNC is printed on the console when the container is started, won't be that be a problem when running it from cloudron ?

[timconsidine]

@cipres Understood about different images
All you can do is try ! Maybe stock image deploys fine on Cloudron

About password, it is possible to view the runtime logs on install.
You just need to tell people to do that.

I can try if you want.
But http://registry.gitlab.com/galacteek/galacteek:pimp-my-dweb-latest-x11vnc comes up as 404 (I will try again)

I don't know how VNC is going to work, but would be interested to find out.

[timconsidine]

@cipres if you have a stock image, I guess it could just be

cloudron install --image http://registry.gitlab.com/galacteek/galacteek:pimp-my-dweb-latest-x11vnc

... providing there is a CloudronManifest.json
Have you made this yet ? Can you share it ?

I tried.
But got this :

$ cloudron install --image http://registry.gitlab.com/galacteek/galacteek:pimp-my-dweb-latest-x11vnc
Location: 3.appx.uk    
Failed to install app: 400 message: Manifest error: Invalid docker image name

Maybe related to that 404 I mentioned
Or something else I don't understand !

EDIT : I don't understand about IPFS or what Galacteek is doing : sorry
