basic docker-compose cluster

[flourgaz]

Run docker-compose up in the base directory of the project, it should build two images and start two containers, one for the app, other for postgres db.

Find the IP of the app container with docker inspect invidious_invidious_1 | grep IPAddress and access that IP address with port 3000 in your browser.

To rebuild the images (after changing anything in the code/dockerfile) run docker-compose build or docker-compose build --no-cache.

The postgres data is in stored in a volume which is set up on first run. If you want to delete that and setup again, remove the volume with docker volume rm invidious_postgresdata (the name might be slightly different if you have the project in different directory, find it with docker volume ls.

Looks really good, I left a couple notes.

Currently the clock CAPTCHA looks like this:

Which I suspect is due to missing dependencies for imagemagick, but I'm having trouble tracking it down. I've tried using librsvg2-dev instead, unfortunately still encountering it.

[flourgaz]

I was playing around with the dependencies and extras for imagemagick, but nothing worked, until I tried building it from ubuntu:xenial, but I'm hesitant to go that far back. I'll try to check what's changed between xenial imagemagick and the current bionic

[flourgaz]

the issue with imagemagick / rsvg is still TODO

[omarroth]

The solution you mentioned with imagemagick actually reminded me that I encountered the same issue when attempting to setup Invidious on DigitalOcean. Using Bionic, I tried building from source, using imagemagick 6.9, installing various other libraries, and ended up using Xenial rather than investigate further.

For reference, here are two different machines that render the CAPTCHA as expected:

yes, I'm pretty sure it's because of the "rsvg" mentioned among the delegates, because the docker bionic version doesn't have it, but the xenial does. Unfortunately I haven't found any other means of getting it there, than compiling imagemagick from sources with a --with-rsvg parameter during the configuration. It seems like the bionic version of the package simply doesn't come with it. I could compile it, but I really wish I wouldn't have to. As far as I read in the tutorials, the build deps are 500MB+

[flourgaz]

Ok, I just found that the artful and bionic versions of imagemagick are explicitly built with --without-rsvg. But the arch linux package still has it. And this is the beauty of docker, I'll simply swap the base image and build it on arch linux ;-)

[flourgaz]

finally got it working on arch, there are couple of basic packages needed for the build and clock needed a font, but it works fine now. And I bound the port to localhost:3000 so now you don't need to look for the IPAddress of the container

[omarroth]

LGTM 👍

[omarroth]

Added instructions in the README, let me know if anything should be changed here or in a new PR.

[flourgaz]

Looks great.
Next step - production docker image automatically built on hub.docker.com. I'll look into it...
