Problem description

Using komodo's Deployments to deploy the paradedb image, I need to map the /var/lib/postgresql/data in the container to the /home/www/komodo-data/data/postgresql on the host. In the Volumes item, I configure /home/www/komodo-data/data/postgresql:/var/lib/postgresql/data. The /home/www/komodo-data/data/postgresql folder will be created by itself, but the container cannot run.
How to configure postgresql:/var/lib/postgresql/data to run normally, but I need to map the data to an absolute path.

Komodo 1.18.1 komodo-periphery latest version, I have checked the documentation and searched for the problem, but no solution was found, or the keywords I searched were wrong?

@mbecker20 commented on GitHub (Aug 28, 2025):

The absolute mount is correct, however if you run Periphery in container, Periphery also needs to be given 1:1 mount inside and outside container in order to work correctly, like is documented for PERIPHERY_ROOT_DIRECTORY. If you can switch to systemd Periphery, it would also fix the issue.
