Headless Version

[tekicat]

Due to the fact PowderWeb is dependent on xdg/gui for intial login. Containerising such and amazing tool had become a nightmare. Is there any plan on releasing a docker container ?

[tekicat]

This may help with head start

FROM ubuntu:18.04

RUN apt update && \
    apt install -y git curl && \ 
    curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash && \
    . ~/.bashrc && \
    nvm install 8.10.0 && \
    . ~/.profile && \
    git clone https://github.com/jaruba/PowderWeb.git && \
    cd PowderWeb && \
    npm install && \
    cd public && \
    npm install -g bower && \
    bower install --allow-root

WORKDIR /PowderWeb/public


ENTRYPOINT ["/bin/bash", "-c"]

CMD ["npm", "start"]

A docker container would be cool. The UI could work as Web only, so a version of Powder Web without Electron should be possible.

But there is a big drawback with this, Electron isn't used just for the Windowed App, it's also used for select folder / file boxes (which Node.js has absolutely no native method for). But selecting folder / file can only be done locally anyway, so it could be changed to a string input that should point to folders / files..

My biggest limitation right now is finding the required time to work on this..

I've renamed this to "Headless Version" and tagging it as a priority task. There might be many other good reasons to have a headless version. It will stay as a priority task unless I can find good enough reasons why Powder Web would dependent on Electron.

[jaruba]

@tekicat I've made a separate branch for the headless version. And did get a version of Powder Web to work completely without Electron.

I never tested it with Docker though, it would sure help if you could test it..

If the lines you previously posted are correct, to use the headless branch you should use:

FROM ubuntu:18.04

RUN apt update && \
    apt install -y git curl && \ 
    curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash && \
    . ~/.bashrc && \
    nvm install 8.10.0 && \
    . ~/.profile && \
    git clone -b headless git@github.com:jaruba/PowderWeb.git && \
    cd PowderWeb && \
    npm install && \
    cd public && \
    npm install -g bower && \
    bower install --allow-root

WORKDIR /PowderWeb/public


ENTRYPOINT ["/bin/bash", "-c"]

CMD ["npm", "run", "start-headless"]

[tekicat]

@jaruba With the below docker file

FROM node:8-alpine3.10

RUN apk add git && \
    npm install -g bower && \
    addgroup -S powderweb && adduser -S powderweb -G powderweb  && \
    mkdir /app && \
    chown -R powderweb:powderweb /app/ 

USER powderweb

WORKDIR /app/

RUN git clone -b headless https://www.github.com/jaruba/PowderWeb.git && \
    cd PowderWeb && \
    npm install && \
    cd public && \
    bower install

WORKDIR /app/PowderWeb/public

ENTRYPOINT ["/bin/sh", "-c"]

CMD ["npm run start-headless"]

I get a 404 on opening http://localhost:3000/auth?token=<master key>

workspace/PowderWeb/docker# docker run -p 3000:3000 powderweb:18.04

> powder-web@0.8.5 start-headless /app/PowderWeb
> node main.js

[ '/usr/local/bin/node', '/app/PowderWeb/main.js' ]
master key: b1b506746eb647bdee953b35fe1abe13
connect ECONNREFUSED 127.0.0.1:80

Am I missing something here ?

[jaruba]

connect ECONNREFUSED 127.0.0.1:80

This seems to be the only error, and it says that something is trying to connect to localhost:80, everything should work on port 3000 so maybe this docker command is wrong somehow?

docker run -p 3000:3000 powderweb:18.04

You could also try using the LAN IP instead of localhost..

Same here, even before trying to open any browser. Just launching "npm run start-headless" get those 2 lines of output (master key + connect ECONNREFUSED 127.0.0.1:80)

Then if I try to open a browser (through internet in my case), I get "404 File Not Found" in the browser and on the server I get something like:
(node:249) TimeoutOverflowWarning: 9007199254740991 does not fit into a 32-bit signed integer.
Timer duration was truncated to 2147483647.
(Use node --trace-warnings ... to show where the warning was created)
(node:249) TimeoutOverflowWarning: 9007199254740991 does not fit into a 32-bit signed integer.
Timer duration was truncated to 2147483647.

I used a totally different DockerFile (to test) I doubt this is linked to Docker

[Tekka90]

FYI, I fiigured out this issue...
After the npm install, I had to run a "npm run build" to build the dist folder....

[Tekka90]

Coming back again for updates on the topic...
So after the build + removing this warning which was annoying (but not an issue)
There was an issue with video-js.
The version present in 0.9 (which is basically commenting some code) is working fine with this headless version.

So now I confirm, that the headless is working in docker. Need to merge all the new changes, and try to keep this version up to date in the future :)

[jaruba]

@Tekka90 Wow, I'm glad to hear u got it working, but the headless branch still needs to be updated to the latest version, and I should release it separately too.

Sorry for the late response, I was on vacation. I'll look into it a bit more too when I have some time, and I always wanted to make an official release of the headless version available.

[jaruba]

@Tekka90 I updated the headless branch to the latest version, but did not test it much, please test it if possible, and also paste the Dockerfile you used that worked for you so I can look into making an official Docker image for Powder Web.

[jaruba]

@Tekka90 if all that was needed was the dist folder, then we should also be able to use npm run build-front instead of npm run build, which is much more lightweight.
