Execution module to work with etcd
:depends: - python-etcd
Configuration
-------------
To work with an etcd server you must configure an etcd profile. The etcd config
can be set in either the Salt Minion configuration file or in pillar:
.. code-block:: yaml
my_etd_config:
etcd.host: 127.0.0.1
etcd.port: 4001
It is technically possible to configure etcd without using a profile, but this
is not considered to be a best practice, especially when multiple etcd servers
or clusters are available.
.. code-block:: yaml
etcd.host: 127.0.0.1
etcd.port: 4001
.. note::
The etcd configuration can also be set in the Salt Master config file,
but in order to use any etcd configurations defined in the Salt Master
config, the :conf_master:`pillar_opts` must be set to ``True``.
Be aware that setting ``pillar_opts`` to ``True`` has security implications
as this makes all master configuration settings available in all minion's
pillars.

Get a value from etcd, by direct path. Returns None on failure.
CLI Examples:

Set a key in etcd by direct path. Optionally, create a directory
or set a TTL on the key. Returns None on failure.
CLI Example:
.. code-block:: bash
salt myminion etcd.set /path/to/key value
salt myminion etcd.set /path/to/key value profile=my_etcd_config
salt myminion etcd.set /path/to/key value host=127.0.0.1 port=2379
salt myminion etcd.set /path/to/dir '' directory=True
salt myminion etcd.set /path/to/key value ttl=5

.. versionadded:: 2016.3.0
Sets a dictionary of values in one call. Useful for large updates
in syndic environments. The dictionary can contain a mix of formats
such as:
.. code-block:: python
{
'/some/example/key': 'bar',
'/another/example/key': 'baz'
}
Or it may be a straight dictionary, which will be flattened to look
like the above format:
.. code-block:: python
{
'some': {
'example': {
'key': 'bar'
}
},
'another': {
'example': {
'key': 'baz'
}
}
}
You can even mix the two formats and it will be flattened to the first
format. Leading and trailing '/' will be removed.
Empty directories can be created by setting the value of the key to an
empty dictionary.
The 'path' parameter will optionally set the root of the path to use.
CLI Example:
.. code-block:: bash
salt myminion etcd.update "{'/path/to/key': 'baz', '/another/key': 'bar'}"
salt myminion etcd.update "{'/path/to/key': 'baz', '/another/key': 'bar'}" profile=my_etcd_config
salt myminion etcd.update "{'/path/to/key': 'baz', '/another/key': 'bar'}" host=127.0.0.1 port=2379
salt myminion etcd.update "{'/path/to/key': 'baz', '/another/key': 'bar'}" path='/some/root'

.. versionadded:: 2016.3.0
Makes a best effort to watch for a key or tree change in etcd.
Returns a dict containing the new key value ( or None if the key was
deleted ), the modifiedIndex of the key, whether the key changed or
not, the path to the key that changed and whether it is a directory or not.
If something catastrophic happens, returns {}
CLI Example:
.. code-block:: bash
salt myminion etcd.watch /path/to/key
salt myminion etcd.watch /path/to/key timeout=10
salt myminion etcd.watch /patch/to/key profile=my_etcd_config index=10

Return all keys and dirs inside a specific path. Returns an empty dict on
failure.
CLI Example:

salt myminion etcd.ls /path/to/dir/
salt myminion etcd.ls /path/to/dir/ profile=my_etcd_config
salt myminion etcd.ls /path/to/dir/ host=127.0.0.1 port=2379

.. versionadded:: 2014.7.0
Delete a key from etcd. Returns True if the key was deleted, False if it was
not and None if there was a failure.
CLI Example:
.. code-block:: bash
salt myminion etcd.rm /path/to/key
salt myminion etcd.rm /path/to/key profile=my_etcd_config
salt myminion etcd.rm /path/to/key host=127.0.0.1 port=2379
