Apache NuGet Repository Hosting

These scripts and xsl transforms, enable hosting of a simple NuGet repository under Apache (on Linux).

Installation (on Fedora)

• If you don't already have Apache:

    # install apache
    sudo dnf install -y httpd
    # start apache
    sudo service httpd start
    # make apache start on system boot
    sudo chkconfig httpd on
  

• If you don't already have incron:

    # install incron
    sudo dnf install -y incron
    # start incron
    sudo service incrond start
    # make incron start on system boot
    sudo chkconfig incrond on
  

• Create your repository:

    sudo mkdir -p /data/repos && sudo chown -R $(whoami):$(whoami) /data
    # clone this tool as your repository root
    git clone https://github.com/grenade/apache-nuget-repo.git /data/repos/nuget
    # create your packages folder
    mkdir /data/repos/nuget/nupkg
    # make generate-manifest executable
    chmod u+x generate-manifest.sh
  

• Configure Apache to host your NuGet repo:

    # if running `getenforce` returns 'Enforcing',
    # run the following command to tell selinux to allow serving up the /data directory
    sudo chcon -R -t httpd_sys_content_t /data
    # modify /data/repos/nuget/misc/data.conf to your liking, then:
    sudo cp /data/repos/nuget/misc/data.conf /etc/httpd/conf.d/
    sudo ln -s /data/repos /var/www/html/
    service httpd restart
  

• Configure incron to regenerate the manifest when changes are detected

    # create an incron user table for your user account:
    sudo cp misc/incron-nuget-repo.conf /var/spool/incron/$(whoami)
    sudo chown root:$(whoami) /var/spool/incron/$(whoami)
    sudo chmod 600 /var/spool/incron/$(whoami)
    # grant permission to run incron jobs to your user account:
    echo $(whoami)> incron.allow
    sudo mv incron.allow /etc/
    sudo service incrond restart
  

• Populate your repo and manifest:

    cd /data/repos/nuget
    # download some packages
    # (optional, but useful for testing, otherwise put your own packages in the nupkg folder)
    chmod u+x /data/repos/nuget/misc/download-some-packages.sh
    ./misc/download-some-packages.sh        
  

Usage

generate-manifest.sh should run (under incron) whenever a package is added or removed from the packages folder. After running the installation instructions above, you should be able to browse packages at http://localhost/repos/nuget/html/

Explanation

The generate-manifest script does the following things (in pretty much the order listed):

• locks execution so that only a single instance of the script can run at a given moment
• changes the current working directory to the folder containing the script
• extracts the .nuspec file from the .nupkg files
• moves the extracted .nuspec file from repo_root/pkg_id.nuspec to repo_root/nuspec/pkg_id.pkg_ver.nuspec
• performs an XSL transform on each .nuspec file to generate an html description of the package at repo_root/html/pkg_id.pkg_ver.html
• creates an array of distinct package ids (package name without the version)
• performs an XSL transform on all .nuspec files to generate an xml manifest of all packages at: repo_root/Packages (file without extension, NuGet convention)
• creates a repo_root/.htaccess file, containing 302 redirects from repo_root/package/pkg_id to the latest version of the package at repo_root/nupkg/pkg_id.pkg_ver.nupkg (NuGet convention for package downloads)
• copies the .nuspec file for the latest version of each package to repo_root/latest/
• performs an xsl transform on all latest version .nuspec files to generate an html index of all latest versions of packages at repo_root/html/index.html
