- ========================
- 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 ZeroMQ 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.
- GitHub page: |saltrepo|
- Wiki: https://github.com/saltstack/salt/wiki
- Arch Linux Package: https://aur.archlinux.org/packages/salt-git/
- 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!
