Salt Formula
============
Salt is a new approach to infrastructure management. Easy enough to get
running in minutes, scalable enough to manage tens of thousands of servers,
and fast enough to communicate with them in seconds.
Salt delivers a dynamic communication bus for infrastructures that can be used
for orchestration, remote execution, configuration management and much more.
Sample Metadata
===============
Salt master
-----------
Salt master with base formulas and pillar metadata backend
.. literalinclude:: tests/pillar/master_single_pillar.sls
:language: yaml
Salt master with reclass ENC metadata backend
.. literalinclude:: tests/pillar/master_single_reclass.sls
:language: yaml
Salt master with API
.. literalinclude:: tests/pillar/master_api.sls
:language: yaml
Salt master with defined user ACLs
.. literalinclude:: tests/pillar/master_acl.sls
:language: yaml
Salt master with preset minions
.. code-block:: yaml
salt:
master:
enabled: true
minions:
- name: 'node1.system.location.domain.com'
Salt master with pip based installation (optional)
.. code-block:: yaml
salt:
master:
enabled: true
...
source:
engine: pip
version: 2016.3.0rc2
Install formula through system package management
.. code-block:: yaml
salt:
master:
enabled: true
...
environment:
prd:
keystone:
source: pkg
name: salt-formula-keystone
nova:
source: pkg
name: salt-formula-keystone
version: 0.1+0~20160818133412.24~1.gbp6e1ebb
postresql:
source: pkg
name: salt-formula-postgresql
version: purged
Formula keystone is installed latest version and the formulas without version are installed in one call to aptpkg module.
If the version attribute is present sls iterates over formulas and take action to install specific version or remove it.
The version attribute may have these values ``[latest|purged|removed|<VERSION>]``.
Clone master branch of keystone formula as local feature branch
.. code-block:: yaml
salt:
master:
enabled: true
...
environment:
dev:
formula:
keystone:
source: git
address: git@github.com:openstack/salt-formula-keystone.git
revision: master
branch: feature

.. code-block:: yaml
salt:
master:
enabled: true
...
environment:
dev:
formula:
keystone:
source: git
address: https://git.openstack.org/openstack/salt-formula-keystone
revision: refs/changes/56/123456/1
Salt master with logging handlers
.. code-block:: yaml
salt:
master:
enabled: true
handler:
handler01:
engine: udp
bind:
host: 127.0.0.1
port: 9999
minion:
handler:
handler01:
engine: udp
bind:
host: 127.0.0.1
port: 9999
handler02:
engine: zmq
bind:
host: 127.0.0.1
port: 9999
Salt master peer setup for remote certificate signing
.. code-block:: yaml
salt:
master:
peer:
".*":
- x509.sign_remote_certificate
Configure verbosity of state output (used for `salt` command)
.. code-block:: yaml
salt:
master:
state_output: changes
Salt synchronise node pillar and modules after start
.. code-block:: yaml
salt:
master:
reactor:
salt/minion/*/start:
- salt://salt/reactor/node_start.sls
Trigger basic node install
.. code-block:: yaml
salt:
master:
reactor:
salt/minion/install:
- salt://salt/reactor/node_install.sls
Sample event to trigger the node installation
.. code-block:: bash
salt-call event.send 'salt/minion/install'
Run any defined orchestration pipeline
.. code-block:: yaml
salt:
master:
reactor:
salt/orchestrate/start:
- salt://salt/reactor/orchestrate_start.sls
Event to trigger the orchestration pipeline
.. code-block:: bash
salt-call event.send 'salt/orchestrate/start' "{'orchestrate': 'salt/orchestrate/infra_install.sls'}"
Add and/or remove the minion key
.. code-block:: yaml
salt:
master:
reactor:
salt/key/create:
- salt://salt/reactor/key_create.sls
salt/key/remove:
- salt://salt/reactor/key_remove.sls
Event to trigger the key creation
.. code-block:: bash
salt-call event.send 'salt/key/create' "{'node_name': 'id-of-minion', 'orch_post_create': 'kubernetes/orchestrate/compute_install.sls'}"
.. note::
You can add pass additional `orch_pre_create`, `orch_post_create`,
`orch_pre_remove` or `orch_post_remove` parameters to the event to call
extra orchestrate files. This can be useful for example for
registering/unregistering nodes from the monitoring alarms or dashboards.
The key creation event needs to be run from other machine than the one
being registered.
Event to trigger the key removal
.. code-block:: bash
salt-call event.send 'salt/key/remove'
