[FIX] LibGL Import Error on docker-compose up

[tezansahu]

Describe the bug

Tried to follow the steps mentioned in 1A. Install Method 1: Docker. Copied the docker-compose.yml file from GitHub & updated the KHOJ_ADMIN_EMAIL & KHOJ_ADMIN_PASSWORD, as mentioned & proceeded to perform docker-compose up.

On performing docker-compose up, the database container (khoj-database-1) starts & keeps running, however the server container (khoj-server-1) tries to starts & exits with the following error: ImportError: libGL.so.1: cannot open shared object file: No such file or directory

Here is the stack trace:

server-1    | Traceback (most recent call last):

server-1    | ImportError: libGL.so.1: cannot open shared object file: No such file or directory

I do see this warning on entering docker-compose up though:

time="2024-07-12T07:07:06+05:30" level=warning msg="C:\\Users\\tezan\\source\\khoj\\docker-compose.yml: `version` is obsolete"`

To Reproduce

Follow the exact steps mentioned in "1A. Install Method 1: Docker" of the Khoj AI docs

Warning is irrelevant.
Seems related to this. Based on comment under linked answer I can assume cv2 requires this. Based on error message I'm assuming rapidOCR needed it.
Putting specified RUN apt-get update && apt-get install ffmpeg libsm6 libxext6 -y under the

# Install RapidOCR dependencies
RUN apt -y install libgl1 libgl1-mesa-glx libglib2.0-0

part and rebuilding image seems to fix the issue. To rebuild, you'll need to comment this line out and uncomment these two.

Cheers.

Hey @tezansahu thanks for raising an issue for this. It was fixed in this PR. You can build from source, like @AnkushMalaker mentioned or update the docker-compose.yml to use the pre tagged docker images.

The latest tagged docker images tracks the latest Khoj release. The fix was done after the previous release. We should have a new release out in a few days as well, in case you want to wait.

Closing this issue as it should be fixed now in the latest release (0.17.0)
