Salt 0.6.0 release notes
|
|
========================
|
|
|
|
The Salt remote execution manager has reached initial functionality! Salt is a
|
|
management application which can be used to execute commands on remote sets of
|
|
servers.
|
|
|
|
The whole idea behind Salt is to create a system where a group of servers can
|
|
be remotely controlled from a single master, not only can commands be executed
|
|
on remote systems, but salt can also be used to gather information about your
|
|
server environment.
|
|
|
|
Unlike similar systems, like Func and MCollective, Salt is extremely simple to
|
|
setup and use, the entire application is contained in a single package, and the
|
|
master and minion daemons require no running dependencies in the way that Func
|
|
requires Certmaster and MCollective requires activeMQ.
|
|
|
|
Salt also manages authentication and encryption. Rather than using ssl for
|
|
encryption, salt manages encryption on a payload level, so the data sent across
|
|
the network is encrypted with fast aes encryption, and authentication uses RSA
|
|
keys. This means that Salt is fast, secure, and very efficient.
|
|
|
|
Messaging in Salt is executed with zeromq, so the message passing interface is
|
|
built into salt and does not require an external MQ server. This also adds
|
|
speed to Salt since there is no additional bloat on the networking layer, and
|
|
zeromq has already proven itself as a very fast networking system.
|
|
|
|
The remote execution in Salt is "Lazy Execution", in that once the command is
|
|
sent the requesting network connection is closed. This makes it easier to
|
|
detach the execution from the calling process on the master, it also means that
|
|
replies are cached, so that information gathered from historic commands can be
|
|
queried in the future.
|
|
|
|
Salt also allows users to make execution modules in python. Writers of these
|
|
modules should also be pleased to know that they have access to the impressive
|
|
information gathered from PuppetLabs' Facter application, making Salt module
|
|
more flexible. In the future I hope to also allow Salt to group servers based
|
|
on facter information as well.
|
|
|
|
All in all Salt is fast, efficient and clean, can be used from a simple command
|
|
line client or through an api, uses message queue technology to make network
|
|
execution extremely fast, and encryption is handled in a very fast and
|
|
efficient manner. Salt is also VERY easy to use and VERY easy to extend.
|
|
|
|
You can find the source code for Salt on my github page, I have also set up a
|
|
few wiki pages explaining how to use and set up Salt. If you are using Arch
|
|
Linux there is a package available in the Arch Linux AUR.

I am very open to contributions, for instance I need packages for more Linux
|
|
distributions as well as BSD packages and testers.
|
|
|
|
Give Salt a try, this is the initial release and is not a 1.0 quality release,
|
|
but it has been working well for me! I am eager to get your feedback!
