About

A Varnish master VMOD to query MaxMind GeoIP2 DB files.

For Varnish 6.0, 7.4 and 7.5 refer to main branch. Older Varnish versions are no longer supported.

Requirements

To build this VMOD you will need:

• make
• a C compiler, e.g. GCC or clang
• pkg-config
• python3-docutils or docutils in macOS [1]
• Varnish master built from sources
• libmaxminddb-dev in recent Debian/Ubuntu releases, maxminddb in macOS [1]. See also https://github.com/maxmind/libmaxminddb

If you are building from Git, you will also need:

• autoconf
• automake
• libtool

You will also need to set PKG_CONFIG_PATH to the directory where varnishapi.pc is located before running autogen.sh and configure. For example:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

Finally, to use it you will need one or more GeoIP2 or GeoLite2 binary databases. See https://dev.maxmind.com/.
