Docker installation broken

[Rafiot]

First of all, I never used Django before, so the issue I encountered might sound obvious, sorry for that.

I tried to install pretalx from the docker documentation (https://docs.pretalx.org/en/latest/administrator/simple_docker.html)

Expected Behavior

Loading https://<url>/ and seeing a page with content.

Current Behavior

Blank page.

Error log:

I never tried to open https://<url>/orga (btw, maybe redirecting to /orga when there are no CFP defined)

Possible Solution

Recommend a tagged version of pretalx (i.e. v0.2.2) in the documentation instead of master.

Your Environment

• Version used: 53491c0
• Server: Ubuntu 16.04 & Docker version 17.09.1-ce, build 19e2cf6

[loelkes]

Seems like the same issue, so i would like to provide additional information.

Expected Behavior

Loading https://<url>/ and seeing a page with content.

Current Behavior

Steps to Reproduce (for bugs)

1. Pull the current git, build the docker and run it (update procedure from the manual).

Context

Installation using the Simple installation using Docker manual by the letter.

Your Environment

• Version used: e9eb4a5
• Server: Linux eventvm 4.9.0-4-amd64 #1 SMP Debian 4.9.65-3 (2017-12-03) x86_64 GNU/Linux

[rixx]

I'm not sure why this started happening now, to be honest. I changed mkdir /data into mkdir /data/logs /data/media in the dockerfile, which might fix the issue, but I don't think so. Investigating.

[rixx]

I have updated the Dockerfile again, and it ought to be fixed. I'll also update the documentation to show that installation via pip is much better supported than installation via Docker. Please reopen this issue if you still encounter the same issue, or create a new one if other things are broken.
Thanks for your reports, both!

[loelkes]

I checked out the release v0.4.1.

There is an immense amount of error message if i try to access the images:

This is from the docker:

During handling of the above exception, another exception occurred:

This is from the nginx (addresses redacted):

Same setup as in the previous issue.

[loelkes]

During docker build i get these weird errors:

docker build --no-cache -t pretalx/pretalx .

Failed building wheel for pretalx

[Janfred]

I've encountered the same issue when deploying with docker.

I only see a page with "Internal Server Error"

[loelkes]

I got it working with ade00e8

Please also see the updated documentation.

[rixx]

Since both @loelkes and I got the docker setup to work independently, I'll close this as fixed.

[Janfred]

I've tried it again with the current master. I still have the same problem.

Is there a public docker container which I could use?

[rixx]

No, there is no public docker container.

If this issue persists, I'll probably rather withdraw the Dockerfiles and installation guide. I'm not familiar enough with Docker to remotely debug other peoples' issues with it, and I won't pretend to offer an installation method I can't/won't support.

[Janfred]

I also tried installation with pip, but I'm on a debian stable and afaik python3.6 is not yet available in the main repositories.
Installing python3.6 from the testing repository broke many things on my server (and I had to manually unistall some packets with things like "force ignore dependencies")
