Execution module to work with etcd

  • python-etcd


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:

  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.
etcd.port: 4001


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 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.

salt.modules.etcd_mod.get(key, recurse=False, profile=None)

New in version 2014.7.0.

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

CLI Examples:

salt myminion etcd.get /path/to/key
salt myminion etcd.get /path/to/key profile=my_etcd_config
salt myminion etcd.get /path/to/key recurse=True profile=my_etcd_config'/', profile=None)

New in version 2014.7.0.

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

CLI Example:

salt myminion /path/to/dir/
salt myminion /path/to/dir/ profile=my_etcd_config
salt.modules.etcd_mod.rm(key, recurse=False, profile=None)

New in version 2014.7.0.

Delete a key from etcd. Returns True if the key was deleted, False if it wasn not and None if there was a failure.

CLI Example:

salt myminion etcd.rm /path/to/key
salt myminion etcd.rm /path/to/key profile=my_etcd_config
salt myminion etcd.rm /path/to/dir recurse=True profile=my_etcd_config
salt.modules.etcd_mod.set(key, value, profile=None, ttl=None, directory=False)

New in version 2014.7.0.

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:

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/dir '' directory=True
salt myminion etcd.set /path/to/key value ttl=5
salt.modules.etcd_mod.tree(path='/', profile=None)

New in version 2014.7.0.

Recurse through etcd and return all values. Returns None on failure.

CLI Example:

salt myminion etcd.tree
salt myminion etcd.tree profile=my_etcd_config
salt myminion etcd.tree /path/to/keys profile=my_etcd_config
salt.modules.etcd_mod.update(fields, path='', profile=None)

New in version 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:

  '/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:

    '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:

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'}" path='/some/root', recurse=False, profile=None, timeout=0, index=None)

New in version 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:

salt myminion /path/to/key
salt myminion /path/to/key timeout=10
salt myminion /patch/to/key profile=my_etcd_config index=10
