serve-svn

Very simple container to run WebSVN viewer and provide access to svn utilities and protocol.

Docker Hub

I am using this container on my Synology NAS to have access to old code - recently DSM 7.0 dropped svn support and I am to lazy to move old code to git.

Normally I run it in read only mode, viewer is fully functional and you could use svn:// protocol to list things:

    sudo docker run -d --name svn -p 4000:80 -p 3690:3690 \
            -e SRV_HOST_PORT=192.168.50.10:4000 \
            -v /volume/docker/svn/data:/home/svn:ro \
            rupor/serve-svn

Since svnadmin does not care about access control lists you could always add more repositories:

	sudo docker exec -t svn svnadmin create /home/svn/<another repo>
	sudo docker exec -t svn svnadmin load /home/svn/<another repo> < dump

It is easy however to get a full access:

    sudo docker run -d --name svn -p 4000:80 -p 3690:3690 \
            -e SRV_HOST_PORT=192.168.50.10:4000 \
            -v /volume4/docker/svn/data:/home/svn \
            -v /volume4/docker/svn/svn/subversion-access-control:/etc/subversion/subversion-access-control \
            -v /volume4/docker/svn/svn/passwd:/etc/subversion/passwd \
            rupor/serve-svn

In this case you may want to change SVN access control lists and add users:

    sudo docker exec -t svn htpasswd -b /etc/subversion/passwd <username> <password>

Technicalities

For some reason Alpine's build of subversion does not have svntools and without svnauthz WebSVN refuses to work. So I had to build my own. Setting up build environment is very simple. I used this to install Alpine 3.14 under WSL2 in Windows 10 (you could use Hyper-V or VirtualBox too) and then followed the official guide. Takes about 3 minutes to complete.

Building Subversion with svnauthz requires a simple patch:

    diff --git a/main/subversion/APKBUILD b/main/subversion/APKBUILD
    index 6eb16766a2..3c20964d76 100644
