I followed the steps of the manual but unfortunately the freshly downloaded container won't stay up for more than a few seconds.

docker logs planka-planka-1 prints the following:

Node.js v18.19.0
/app/node_modules/.pnpm/sharp@0.33.2/node_modules/sharp/lib/sharp.js:114
  throw new Error(help.join('\n'));
        ^

Error: Could not load the "sharp" module using the linuxmusl-arm runtime
Possible solutions:
- Manually install libvips >= 8.15.1
- Add experimental WebAssembly-based dependencies:
    npm install --cpu=wasm32 sharp
    npm install @img/sharp-wasm32
- Consult the installation documentation:
    See https://sharp.pixelplumbing.com/install

    at Module._extensions..js (node:internal/modules/cjs/loader:1414:10)

I also wasn't able to manually install the needed packages because of the restart of the container.

Solved the issue:
The problem was the unsupported 32 bit kernel.
I upgraded (reinstalled) Raspbian and the container starts normally.
Unfortunately, the web interface does not show any content. Just the following error message appears in the brwoser console:

Hi Marvin,

are you opening Planka on the Pi itself, or from a remote Computer?

If you want to access Planka from a remote Computer, you have to put the Ip of the Pi into the BASE_URL variable
Something like this http://192.168.0.100:16900

I have the same problem. My base URL says: - BASE_URL=http://planka.local I am using port 80.
This then runs for a few hours and then it constantly restarts.

How do I get a log file from Planka? The file /app/logs/planka.log in the container is empty.
