Re: JNS: Juju Name Server

It would need additional work, too, because JNS requires the Juju client credentials to exist (though I think there's a charm layer for things that need that).

Re: JNS: Juju Name Server
That's an awesome idea and tool Andrew thanks for sharing. Any plans for turning it into a charm?

JNS: Juju Name Server
Hi, A little while ago, I found myself wanting to address a service by its Juju name, but outside of Juju. I didn't want to be tied to an IP/host name, because they might change; I didn't want to be tied to any one cloud provider; and I wanted it to work across environments. So I wrote a little DNS server that resolves Juju entity names to IP addresses. It's called "jns", Juju Name Server. You can find it here: https://github.com/axw/jns (go get github.com/axw/jns) Names take one of the following forms: 0.juju# machine 0 machine-0-lxc-0.juju # machine 0/lxc/0 mysql.juju # IP address of a random unit of the mysql service unit-mysql-0.juju # IP address of mysql/0 In the above forms, the entity is within the current environment. If you want to resolve the address of an entity in another environment, you can precede ".juju" with the name of the environment. e.g. mysql.prod.juju mysql.dev.juju etc. Enjoy.
