vbond/docker-etcd-registrator repository overview

https://github.com/vlad-x/docker-etcd-registrator⁠

This is a fork of psi-4ward/docker-etcd-registrator⁠ with built-in DNS server for simplier setup. Adds two parameters BUILTIN_DNS_PROXY (e.g. BUILTIN_DNS_PROXY=8.8.8.8) which enables the built-in DNS server (and disables the rest of the backend), and ETCD_PREFIX (default ETCD_PREFIX='/dockerdns') which is also used as the base domain for the DNS entries. Each docker container gets multiple domain names to be used for discovery in different scenarios:

• <docker-image-name>.<base-domain>
• <parent-host>.<docker-image-name>.<base-domain>
• <docker-container-name>.<base-domain>
• <parent-host>.<docker-container-name>.<base-domain>

e.g. the following DNS entries will be created for a container running RethinkDB started with --name rethinkdb-main on host production1:

• rethinkdb.dockerdns
• production1.rethinkdb.dockerdns
• rethinkdb-main.dockerdns
• production1.rethinkdb-main.dockerdns
