| A fair definition. If they're anything like mine, the hosts probably have unique hostnames but share the remaining 99% of the nginx config. Is that identical portion a "package" or "configuration"? I think there are a few more steps in there. Assuming identical OS and arch, you've probably got: * software packages that should be identical on all nodes in the cluster * a set of software packages that should be installed on all nodes * configuration that should be identical (e.g. 99% of an nginx config) * configuration that is unique to the host (e.g. a hostname) Or perhaps: * packages limited to a single OS (traditional software packages for Linux) * packages limited to a single organization (identical portions of configs) * packages limited to a single node (hostname) Anyway, I'm playing around with using Nix for all but the unique-per-host stuff. I see potential, but it may or may not pan out. I seem to always need a custom version of nginx, or ruby, and I find making custom Debian packages rather cumbersome, even with a fair amount of experience. |
