Starting with salt -- hello world

[Jeff Abrahamson]

I'm trying to get started with salt after lots of reading of docs.  I'm clearly missing something.  The goal at the moment is to get a minimal masterless example running to convince myself that I can do anything.  I'm doing this on a vagrant instance.  Once I have this working, I'll convince myself I can deploy to a real (linode vps) host.  Once that's working, the plan is to start using a salt master.  One thing at a time.  I'm moving our infra from puppet, so the plan is to move responsibilities one at a time from puppet to salt.

Let's start by creating a file.

In both /etc/salt/{master,minion}, I've added these lines:

    file_roots:
      base:
    - /srv/salt

And I have created these files:

    ubuntu@tyne1:~$ find /srv
    /srv
    /srv/salt
    /srv/salt/jeff
    /srv/salt/jeff/jeff
    /srv/salt/jeff/init.cls
    /srv/salt/top.cls
    ubuntu@tyne1:~$

== top.cls ==
base:
  '*':
    - jeff

== jeff/init.cls ==
/tmp/jeff:
  file.managed:
    - source: salt://jeff/jeff
    - user: ubuntu
    - group: ubuntu
    - mode: 400

== jeff/jeff ==
Hello, world!

So now I'd like to get salt to create that little file in /tmp/.

Any pointers to what I'm missing or not understanding?

Hi Jeff,

state files are .sls not .cls

Jeff,

Welcome to saltstack! I like your approach of beginning with salt
masterless, the gradually refactoring your setup into saltstack; I
started the same way!

As for your issue, I noticed a typo in your file names:

You're using the '.cls' extension; salt will be looking for '.sls' as
you can see in the output:

> [DEBUG ] Could not find file 'salt://top.sls' in saltenv 'base'

Hope this helps. Happy Friday!

Thanks for the validation on that one, the near absence of that advice
in the docs and blogs has had me worried that I was really confused.

D'oh!  Thanks!  That also sorts out the problem that emacs keeps
thinking that latex mode would be appropriate. ;-)
