Hi, thank you for writing this article. I was wondering how you made sure that the elasticsearch is not unprotected (unprotected elastic searches are a common occurence of data leakage)

[FarisZR]

You are correct, it's not secure. I made this for mainly for local use, but since elastic search is only exposed to the docker network, without any port forwarding it shouldn't be an issue, unless Nextcloud or the server itself gets hacked of course.

Hi,

I have Nextcloud AIO but cant get OCR on Images not working.

workflow_pdf_converter could not convert /admin/files/Documents/bbn3.docx, reason: [] 2023-11-02T12:30:41+0100
workflow_pdf_converter Can not find office path. Please make sure to configure "preview_libreoffice_path" in your config file.

[FarisZR]

This shouldn't be too hard to fix.
you need to add libreoffice to the command sub-element for the container in compose.
they don't do this by default because installing libreoffice requires a lot of dependencies.

Hi, i dont understand "add libreoffice command"

[FarisZR]

the command element in docker compose for Nextcloud and cron.
it may be command: sh -c "apt update && apt-get install -y --no-install-recommends tesseract-ocr tesseract-ocr-eng tesseract-ocr-$(YOUR_THREE_LETTER_LANGUAGE_CODE) && /entrypoint.sh apache2-foreground" if you use debian
you just have to add libreoffice to the package list:

command: sh -c "apt update && apt-get install -y --no-install-recommends tesseract-ocr tesseract-ocr-eng tesseract-ocr-$(YOUR_THREE_LETTER_LANGUAGE_CODE) libreoffice && /entrypoint.sh apache2-foreground"
