ownCloud docker compose installation raspi 4 failed: mariadb manifest

hardware: raspberry pi 4
os: Linux piwork 5.10.63-v7l+ #1496 SMP Wed Dec 1 15:58:56 GMT 2021 armv7l GNU/Linux
Raspbian GNU/Linux 10 (buster)

i struggle to install owncloud with docker based on the documentation.
(the quick evaluation works) It is an issue with the installation based on docker composer.
the installation fails for mariadb with the error-message: no matching manifest for linux/arm/v7 in the manifest list entries

when i change the image of mariadb in the yaml file to “linuxserver/mariadb” the installation works, but the container is restarting endless.

what can i do to fix this?

  • install raspberry pi os 64 bit version?
  • use a specific older version of mariadb?

thanks for your support

with the following changes in the yaml file it worked:

  • changed image to linuxserver/mariadb
  • removed command entry, as for some reasons those commands are not understood by that container

any comments? it that the right approach?
