Realms-wiki docker container doesn't work due to missing cleancss

[webpigeon]

Hello,

The docker instance now boots, which is good news :), however, upon visiting the page in the browser (http://servername:5000) I am greeted with a 500 error.

docker logs realms-wiki shows the following:

The steps used to create the docker container are:

docker pull realms/realms-wiki
docker run --name realms-wiki -p 5000:5000 -d realms/realms-wiki

[webpigeon]

short term fix: Remote into the docker container as root: docker exec -u 0 -it realms-wiki /bin/bash

install clean-css from npm npm install -g clean-css

Refreshing the page in the web browser then results in the realms wiki page (all be it without icons) and some javascript errors - it seems to be trying to load stuff from file paths rather than relative to the url in the stylesheet:

@font-face {
    font-family:'Glyphicons Halflings';
    src:url(/home/wiki/realms-wiki/realms/static/vendor/bootswatch-dist/fonts/glyphicons-halflings-regular.eot);
    src:url(/home/wiki/realms-wiki/realms/static/vendor/bootswatch-dist/fonts/glyphicons-halflings-regular.eot?#iefix) format('embedded-opentype'),url(/home/wiki/realms-wiki/realms/static/vendor/bootswatch-dist/fonts/glyphicons-halflings-regular.woff2) format('woff2'),url(/home/wiki/realms-wiki/realms/static/vendor/bootswatch-dist/fonts/glyphicons-halflings-regular.woff) format('woff'),url(/home/wiki/realms-wiki/realms/static/vendor/bootswatch-dist/fonts/glyphicons-halflings-regular.ttf) format('truetype'),url(/home/wiki/realms-wiki/realms/static/vendor/bootswatch-dist/fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular) format('svg')
}

I'm guessing that chaging line 9 of the dockerfile from: npm install -g bower to npm install -g bower clean-css

might fix the missing cleancss problem

[uxDaniel]

Indeed, I had the same issue and went ahead to solve it: PR #175

[scragg0x]

pulled #175

[RheaUN]

I can confim. The issue is still present and can be reproduced by:

docker run --name realms-wiki -p 5000:5000 -d realms/realms-wiki

[bhavicp]

This is still happening.

[scragg0x]

Sorry about this. I am confirming the docker image is busted. I have done some work on a new one that will be automatically updated on commit. There is an issue that requires some code changes as well.

[RheaUN]

Hello scragg0x, THX for the short info. It is definitively a nice piece of code. Thumbs up!

[roycepope]

Was this ever resolved? I am still running into the Internal Server Error message even after trying the steps listed above.

Here is my output:

[roycepope:~]$ docker exec -u 0 -it realms-wiki /bin/bash

[chjohnst]

that did the trick!

[eric-schleicher]

Is it possible to get a push of the docker image? the fix from the recent commits don't appear to have been updates in the docker repo.

[scragg0x]

Should be resolved, try the latest docker image
