Salt Proxy Minion End-to-End Example
|
|
====================================
|
|
|
|
The following is walkthrough that documents how to run a sample REST service
|
|
and configure one or more proxy minions to talk to and control it.
|
|
|
|
1. Ideally, create a Python virtualenv in which to run the REST service. This
|
|
is not strictly required, but without a virtualenv you will need to install
|
|
``bottle`` via pip globally on your system
|
|
|
|
2. Clone https://github.com/saltstack/salt-contrib
|
|
and copy the contents of the directory ``proxyminion_rest_example``
|
|
somewhere on a machine that is reachable from the machine on which you want to
|
|
run the salt-proxy. This machine needs Python 2.7 or later.
|
|
|
|
3. Install bottle version 0.12.8 via pip or easy_install
|
|
|
|
.. code-block:: bash
|
|
|
|
pip install bottle==0.12.8
|
|
|
|
4. Run ``python rest.py --help`` for usage
|
|
|
|
5. Start the REST API on an appropriate port and IP.
|
|
|
|
6. Load the REST service's status page in your browser by going to the IP/port
|
|
combination (e.g. http://127.0.0.1:8000)
|
|
|
|
7. You should see a page entitled "Salt Proxy Minion" with two sections,
|
|
one for "services" and one for "packages" and you should see a log entry in
|
|
the terminal where you started the REST process indicating that the index
|
|
page was retrieved.
|
|
|
|
|
|

|
|
|
|
Now, configure your salt-proxy.
|
|
|
|
1. Edit ``/etc/salt/proxy`` and add an entry for your master's location
|
|
|
|
.. code-block:: yaml
|
|
|
|
master: localhost
|
|
|
|
2. On your salt-master, ensure that pillar is configured properly. Select an ID
|
|
for your proxy (in this example we will name the proxy with the letter 'p'
|
|
followed by the port the proxy is answering on). In your pillar topfile,
|
|
place an entry for your proxy:
|
|
|
|
.. code-block:: yaml
|
|
|
|
base:
|
|
'p8000':
|
|
- p8000
|
|
|
|
|
|
This says that Salt's pillar should load some values for the proxy ``p8000``
|
|
from the file /srv/pillar/p8000.sls (if you have not changed your default pillar_roots)
|
|
|
|
3. In the pillar root for your base environment, create this file:
|
|
|
|
|
|
.. code-block:: yaml
|
|
|
|
p8000.sls
|
|
---------
|
|
|
|
proxy:
|
|
proxytype: rest_sample
|
|
url: http://<IP your REST listens on>:port
|
|
|
|
In other words, if your REST service is listening on port 8000 on 127.0.0.1
|
|
the 'url' key above should say ``url: http://127.0.0.1:8000``
|
|
|
|
4. Make sure your salt-master is running.
|
|
|
|
5. Start the salt-proxy in debug mode
|
|
|
|
.. code-block:: bash
|
|
|
|
salt-proxy --proxyid=p8000 -l debug
|
|
|
|
6. Accept your proxy's key on your salt-master
|
|
|
|
.. code-block:: bash
|
|
|
|
salt-key -y -a p8000
|
|
The following keys are going to be accepted:
|
|
Unaccepted Keys:
|
|
p8000
|
|
Key for minion p8000 accepted.
|
|
|
|
7. Now you should be able to ping your proxy. When you ping, you should see
|
|
a log entry in the terminal where the REST service is running.
|
|
|
|
.. code-block:: bash
|
|
|
|
salt p8000 test.ping
|
|
|
|
8. The REST service implements a degenerately simple pkg and service provider as
|
|
well as a small set of grains. To "install" a package, use a standard
|
|
``pkg.install``. If you pass '==' and a verrsion number after the package
|
|
name then the service will parse that and accept that as the package's
|
|
version.
|
|
|
|
9. Try running ``salt p8000 grains.items`` to see what grains are available. You
|
|
can target proxies via grains if you like.
|
|
|
|
10. You can also start and stop the available services (apache, redbull, and
|
|
postgresql with ``service.start``, etc.
|
|
|
|
11. States can be written to target the proxy. Feel free to experiment with
|
|
them.
