a docker container, base on latest ubuntu docker (20.04), with subversion (svn-server) 1.13, with https support (no certificat management) and interface for management iF.SvnAdmin
download and extract in ./build/iF.SvnAdmin/ https://svnadmin.insanefactory.com/

I use docker container with jwilder/nginx-proxy with the jrcs/letsencrypt-nginx-proxy-companion/ to manage letsencrypt certificat. https://registry.hub.docker.com/r/jwilder/nginx-proxy/ https://registry.hub.docker.com/r/jrcs/letsencrypt-nginx-proxy-companion/
inspire from https://github.com/MarvAmBass/docker-subversion but limited to svn 1.9 so I decided to restart from 0 to be able to make update
for configuration exemple, follow the screen capture from this webpage https://kb.synology.com/en-my/DSM/tutorial/How_to_launch_an_SVN_server_based_on_Docker_on_your_Synology_NAS
#Install tips //Copy everything in one folder cd build //svn-server will be the name of the image from wich you can launch several containers if needed docker build -t svn-server .
