Saltstack Workshop

Introduction

Saltstack is a configuration management platform for managing large infrastructure. This workshop sets you up with a small cluster on your laptop and then walks through key concepts with explanations and hands on code & demo. You can follow along the tutorial trail and learn Saltstack. All you need is a laptop with sufficient resources to run a few VMs.

saltstack-cluster's Issues

salt '*' state.highstate fails with current salt ver. 2017.7.2

Thank you so much for this nice mini cluster setup.

But something seems to be broken with current version of salt --version 2017.7.2 ?

When I run sudo salt '*' state.highstate

sudo salt '*' state.highstate
smaster.learn.com:
----------
          ID: states
    Function: no.None
      Result: False
     Comment: No Top file or master_tops data matches found.

Also the /vagrant/salt/srv/salt/top.sls file contains:

base:
  'G@roles:apache':
    - apache
  'G@roles:redis':
    - redis.server

But a sudo salt '*' state.show_top shows empty or non-exixstent top file?

sudo salt '*' state.show_top
0.sagent.learn.com:
    ----------
1.sagent.learn.com:
    ----------
smaster.learn.com:
    ----------

Which explains why the highstate fails? But I don't know why it doesn't find and run the highstate under this version? Is this a salt version regression?

The active salt master config file is:
sudo cat -tve /etc/salt/master | egrep -v '^#|^\$'

 file_roots:$
   base:$
     - /srv/salt$
     - /vagrant/salt/srv/salt$
 pillar_roots:$
   base:$
     - /srv/pillar$
     - /vagrant/salt/srv/pillar$

all the required (and un-edited) files from your git repo are there ls -R /vagrant/salt/srv/salt/

/vagrant/salt/srv/salt/:
apache  orch  redis  redis_key_check.sls  top.sls

/vagrant/salt/srv/salt/apache:
apache_down.sls  files  init.sls

/vagrant/salt/srv/salt/apache/files:
index.html.jinja

/vagrant/salt/srv/salt/orch:
flow1.sls

/vagrant/salt/srv/salt/redis:
common.sls  files  init.sls  map.jinja  server.sls

/vagrant/salt/srv/salt/redis/files:
redis-2.4.conf.jinja  redis-2.8.conf.jinja  redis-3.2.conf.jinja  upstart.conf.jinja
redis-2.6.conf.jinja  redis-3.0.conf.jinja  redis_initd.jinja

And I had added the apache role grain

sudo salt '*' cmd.run 'cat /etc/salt/grains'

1.sagent.learn.com:
    role:
    - apache
0.sagent.learn.com:
    role:
    - apache
smaster.learn.com:
    role:
    - apache

Any idea what is going on here?
