At runtime, HAProxy uses the IP addresses provided by the nameserver directives. At configuration parsing time, HAProxy uses the libc, hence resolv.conf. The runtime resolver don't read the resolv.conf file. As a workaround, your init script may be able to update the cfg file quite easily. This gave me an idea, since you speak about automation :) We could improve the "resolvers" section parser with a couple of new features: - parsing a 'resolv.conf' file style (you provide a path to the file) to read the nameserver directives only (for now) - using environment variables Baptiste
