Radicale doesn't include 'radicale_auth_matrix' python module

[igogold]

I've enabled Radicale and configure to auth via matrix like in defaults/main.yaml:

radicale_enabled: true

radicale_hostname: 'mash.mydomain.com'
radicale_path_prefix: '/radicale'

radicale_auth_type: 'radicale_auth_matrix'
radicale_auth_matrix_server: 'matrix.mydomain.com'

But got in the journal:

How to add module 'radicale_auth_matrix' to Radicale docker image? I think an image already has it but it doesn't.

[etkecc]

it's a custom module we've developed, and it's not included within the default docker image
you can use the https://gitlab.com/etke.cc/radicale docker image instead (registry.gitlab.com/etke.cc/radicale:3.1.8.3)
