.. _salt-cloud-config:
==================
Core Configuration
==================
A number of core configuration options and some options that are global to the
VM profiles can be set in the cloud configuration file. By default this file is
located at ``/etc/salt/cloud``.
Thread Pool Size
================
When salt cloud is operating in parallel mode via the ``-P`` argument, you can
control the thread pool size by specifying the ``pool_size`` parameter with
a positive integer value.
By default, the thread pool size will be set to the number of VMs that salt
cloud is operating on.
.. code-block:: yaml
pool_size: 10
Minion Configuration
====================
The default minion configuration is set up in this file. Minions created by
salt-cloud derive their configuration from this file. Almost all parameters
found in :ref:`Configuring the Salt Minion <configuration-salt-minion>` can
be used here.
.. code-block:: yaml
minion:
master: saltmaster.example.com
In particular, this is the location to specify the location of the salt master
and its listening port, if the port is not set to the default.
Similar to most other settings, Minion configuration settings are inherited
across configuration files. For example, the master setting might be contained
in the main ``cloud`` configuration file as demonstrated above, but additional
settings can be placed in the provider or profile:
.. code-block:: yaml
ec2-web:
size: t1.micro
minion:
environment: test
startup_states: sls
sls_list:
- web
Cloud Configuration Syntax
==========================
The data specific to interacting with public clouds is set up :ref:`here
<cloud-provider-specifics>`.
Cloud provider configuration settings can live in several places. The first is in
``/etc/salt/cloud``:
.. code-block:: yaml
# /etc/salt/cloud
providers:
my-aws-migrated-config:
id: HJGRYCILJLKJYG
key: 'kdjgfsgm;woormgl/aserigjksjdhasdfgn'
keyname: test
securitygroup: quick-start
private_key: /root/test.pem
driver: ec2
Cloud provider configuration data can also be housed in ``/etc/salt/cloud.providers``
or any file matching ``/etc/salt/cloud.providers.d/*.conf``. All files in any of these
locations will be parsed for cloud provider data.
Using the example configuration above:
.. code-block:: yaml
# /etc/salt/cloud.providers
# or could be /etc/salt/cloud.providers.d/*.conf
my-aws-config:
id: HJGRYCILJLKJYG
key: 'kdjgfsgm;woormgl/aserigjksjdhasdfgn'
keyname: test
securitygroup: quick-start
private_key: /root/test.pem
driver: ec2
.. note::
Salt Cloud provider configurations within ``/etc/cloud.provider.d/`` should not
specify the ``providers`` starting key.
It is also possible to have multiple cloud configuration blocks within the same alias block.
For example:
.. code-block:: yaml
production-config:
- id: HJGRYCILJLKJYG
key: 'kdjgfsgm;woormgl/aserigjksjdhasdfgn'
keyname: test
securitygroup: quick-start
private_key: /root/test.pem
driver: ec2
- user: example_user
apikey: 123984bjjas87034
driver: rackspace
However, using this configuration method requires a change with profile configuration blocks.
The provider alias needs to have the provider key value appended as in the following example:
.. code-block:: yaml
rhel_aws_dev:
provider: production-config:ec2
image: ami-e565ba8c
size: t1.micro
rhel_aws_prod:
provider: production-config:ec2
image: ami-e565ba8c
size: High-CPU Extra Large Instance
database_prod:
provider: production-config:rackspace
image: Ubuntu 12.04 LTS
size: 256 server
Notice that because of the multiple entries, one has to be explicit about the provider alias and
name, from the above example, ``production-config: ec2``.
This data interactions with the ``salt-cloud`` binary regarding its ``--list-location``,
``--list-images``, and ``--list-sizes`` which needs a cloud provider as an argument. The argument
used should be the configured cloud provider alias. If the provider alias has multiple entries,
``<provider-alias>: <provider-name>`` should be used.
To allow for a more extensible configuration, ``--providers-config``, which defaults to
``/etc/salt/cloud.providers``, was added to the cli parser. It allows for the providers'
configuration to be added on a per-file basis.
Pillar Configuration
====================
It is possible to configure cloud providers using pillars. This is only used when inside the cloud
module. You can setup a variable called ``cloud`` that contains your profile and provider to pass
that information to the cloud servers instead of having to copy the full configuration to every
minion. In your pillar file, you would use something like this:
.. code-block:: yaml
cloud:
ssh_key_name: saltstack
ssh_key_file: /root/.ssh/id_rsa
update_cachedir: True
diff_cache_events: True
change_password: True
providers:
my-nova:
identity_url: https://identity.api.rackspacecloud.com/v2.0/
compute_region: IAD
user: myuser
api_key: apikey
tenant: 123456
driver: nova
my-openstack:
identity_url: https://identity.api.rackspacecloud.com/v2.0/tokens
user: user2
apikey: apikey2
tenant: 654321
compute_region: DFW
driver: openstack
compute_name: cloudServersOpenStack
profiles:
ubuntu-nova:
provider: my-nova
size: performance1-8
image: bb02b1a3-bc77-4d17-ab5b-421d89850fca
script_args: git develop
ubuntu-openstack:
provider: my-openstack
size: performance1-8
image: bb02b1a3-bc77-4d17-ab5b-421d89850fca
script_args: git develop
Cloud Configurations
====================
Scaleway
--------
To use Salt Cloud with Scaleway, you need to get an ``access key`` and an ``API token``. ``API tokens`` are unique identifiers associated with your Scaleway account.
To retrieve your ``access key`` and ``API token``, log-in to the Scaleway control panel, open the pull-down menu on your account name and click on "My Credentials" link.
If you do not have ``API token`` you can create one by clicking the "Create New Token" button on the right corner.
.. code-block:: yaml
my-scaleway-config:
access_key: 15cf404d-4560-41b1-9a0c-21c3d5c4ff1f
token: a7347ec8-5de1-4024-a5e3-24b77d1ba91d
driver: scaleway
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: my-scaleway-config``.
Rackspace
---------
Rackspace cloud requires two configuration options; a ``user`` and an ``apikey``:
.. code-block:: yaml
my-rackspace-config:
user: example_user
apikey: 123984bjjas87034
driver: rackspace
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: my-rackspace-config``.
Amazon AWS
----------
A number of configuration options are required for Amazon AWS including ``id``,
``key``, ``keyname``, ``securitygroup``, and ``private_key``:
.. code-block:: yaml
my-aws-quick-start:
id: HJGRYCILJLKJYG
key: 'kdjgfsgm;woormgl/aserigjksjdhasdfgn'
keyname: test
securitygroup: quick-start
private_key: /root/test.pem
driver: ec2
my-aws-default:
id: HJGRYCILJLKJYG
key: 'kdjgfsgm;woormgl/aserigjksjdhasdfgn'
keyname: test
securitygroup: default
private_key: /root/test.pem
driver: ec2
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be either ``provider: my-aws-quick-start``
or ``provider: my-aws-default``.
Linode
------
Linode requires a single API key, but the default root password also needs to
be set:
.. code-block:: yaml
my-linode-config:
apikey: asldkgfakl;sdfjsjaslfjaklsdjf;askldjfaaklsjdfhasldsadfghdkf
password: F00barbaz
ssh_pubkey: ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIKHEOLLbeXgaqRQT9NBAopVz366SdYc0KKX33vAnq+2R user@host
ssh_key_file: ~/.ssh/id_ed25519
driver: linode
The password needs to be 8 characters and contain lowercase, uppercase, and
numbers.
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: my-linode-config``
Joyent Cloud
------------
The Joyent cloud requires three configuration parameters: The username and
password that are used to log into the Joyent system, as well as the location
of the private SSH key associated with the Joyent account. The SSH key is needed
to send the provisioning commands up to the freshly created virtual machine.
.. code-block:: yaml
my-joyent-config:
user: fred
password: saltybacon
private_key: /root/joyent.pem
driver: joyent
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: my-joyent-config``
GoGrid
------
To use Salt Cloud with GoGrid, log into the GoGrid web interface and create an
API key. Do this by clicking on "My Account" and then going to the API Keys
tab.
The ``apikey`` and the ``sharedsecret`` configuration parameters need to
be set in the configuration file to enable interfacing with GoGrid:
.. code-block:: yaml
my-gogrid-config:
apikey: asdff7896asdh789
sharedsecret: saltybacon
driver: gogrid
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: my-gogrid-config``.
OpenStack
---------
OpenStack configuration differs between providers, and at the moment several
options need to be specified. This module has been officially tested against
the HP and the Rackspace implementations, and some examples are provided for
both.
.. code-block:: yaml
# For HP
my-openstack-hp-config:
identity_url:
'https://region-a.geo-1.identity.hpcloudsvc.com:35357/v2.0/'
compute_name: Compute
compute_region: 'az-1.region-a.geo-1'
tenant: myuser-tenant1
user: myuser
ssh_key_name: mykey
ssh_key_file: '/etc/salt/hpcloud/mykey.pem'
password: mypass
driver: openstack
# For Rackspace
my-openstack-rackspace-config:
identity_url: 'https://identity.api.rackspacecloud.com/v2.0/tokens'
compute_name: cloudServersOpenStack
protocol: ipv4
compute_region: DFW
user: myuser
tenant: 5555555
password: mypass
driver: openstack
If you have an API key for your provider, it may be specified instead of a
password:
.. code-block:: yaml
my-openstack-hp-config:
apikey: 901d3f579h23c8v73q9
my-openstack-rackspace-config:
apikey: 901d3f579h23c8v73q9
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be either ``provider: my-openstack-hp-config``
or ``provider: my-openstack-rackspace-config``.
You will certainly need to configure the ``user``, ``tenant``, and either
``password`` or ``apikey``.
If your OpenStack instances only have private IP addresses and a CIDR range of
private addresses are not reachable from the salt-master, you may set your
preference to have Salt ignore it:
.. code-block:: yaml
my-openstack-config:
ignore_cidr: 192.168.0.0/16
For in-house OpenStack Essex installation, libcloud needs the service_type :
.. code-block:: yaml
my-openstack-config:
identity_url: 'http://control.openstack.example.org:5000/v2.0/'
compute_name : Compute Service
service_type : compute
DigitalOcean
------------
Using Salt for DigitalOcean requires a ``client_key`` and an ``api_key``. These
can be found in the DigitalOcean web interface, in the "My Settings" section,
under the API Access tab.
.. code-block:: yaml
my-digitalocean-config:
driver: digital_ocean
personal_access_token: xxx
location: New York 1
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: my-digital-ocean-config``.
Parallels
---------
Using Salt with Parallels requires a ``user``, ``password`` and ``URL``. These
can be obtained from your cloud provider.
.. code-block:: yaml
my-parallels-config:
user: myuser
password: xyzzy
url: https://api.cloud.xmission.com:4465/paci/v1.0/
driver: parallels
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: my-parallels-config``.
Proxmox
-------
Using Salt with Proxmox requires a ``user``, ``password``, and ``URL``. These can be
obtained from your cloud host. Both PAM and PVE users can be used.
.. code-block:: yaml
my-proxmox-config:
driver: proxmox
user: saltcloud@pve
password: xyzzy
url: your.proxmox.host
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: my-proxmox-config``.
LXC
---
The lxc driver uses saltify to install salt and attach the lxc container as a new lxc
minion. As soon as we can, we manage baremetal operation over SSH. You can also destroy
those containers via this driver.
.. code-block:: yaml
devhost10-lxc:
target: devhost10
driver: lxc
And in the map file:
.. code-block:: yaml
devhost10-lxc:
provider: devhost10-lxc
from_container: ubuntu
backing: lvm
sudo: True
size: 3g
ip: 10.0.3.9
minion:
master: 10.5.0.1
master_port: 4506
lxc_conf:
- lxc.utsname: superlxc
.. note::
In the cloud profile that uses this provider configuration, the syntax for the
``provider`` required field would be ``provider: devhost10-lxc``.
.. _config_saltify:
Saltify
-------
The Saltify driver is a new, experimental driver designed to install Salt on a remote
machine, virtual or bare metal, using SSH. This driver is useful for provisioning
machines which are already installed, but not Salted. For more information about using
this driver and for configuration examples, please see the
:ref:`Gettting Started with Saltify <getting-started-with-saltify>` documentation.
Extending Profiles and Cloud Providers Configuration
====================================================
As of 0.8.7, the option to extend both the profiles and cloud providers
configuration and avoid duplication was added. The extends feature works on the
current profiles configuration, but, regarding the cloud providers
configuration, **only** works in the new syntax and respective configuration
files, i.e. ``/etc/salt/salt/cloud.providers`` or
``/etc/salt/cloud.providers.d/*.conf``.
.. note::
Extending cloud profiles and providers is not recursive. For example, a
profile that is extended by a second profile is possible, but the second
profile cannot be extended by a third profile.
Also, if a profile (or provider) is extending another profile and each
contains a list of values, the lists from the extending profile will
override the list from the original profile. The lists are not merged
together.
Extending Profiles
------------------
Some example usage on how to use ``extends`` with profiles. Consider
``/etc/salt/salt/cloud.profiles`` containing:
.. code-block:: yaml
development-instances:
provider: my-ec2-config
size: t1.micro
ssh_username: ec2_user
securitygroup:
- default
deploy: False
Amazon-Linux-AMI-2012.09-64bit:
image: ami-54cf5c3d
extends: development-instances
Fedora-17:
image: ami-08d97e61
extends: development-instances
CentOS-5:
provider: my-aws-config
image: ami-09b61d60
extends: development-instances
The above configuration, once parsed would generate the following profiles
data:
.. code-block:: python
[{'deploy': False,
'image': 'ami-08d97e61',
'profile': 'Fedora-17',
'provider': 'my-ec2-config',
'securitygroup': ['default'],
'size': 't1.micro',
'ssh_username': 'ec2_user'},
{'deploy': False,
'image': 'ami-09b61d60',
'profile': 'CentOS-5',
'provider': 'my-aws-config',
'securitygroup': ['default'],
'size': 't1.micro',
'ssh_username': 'ec2_user'},
{'deploy': False,
'image': 'ami-54cf5c3d',
'profile': 'Amazon-Linux-AMI-2012.09-64bit',
'provider': 'my-ec2-config',
'securitygroup': ['default'],
'size': 't1.micro',
'ssh_username': 'ec2_user'},
{'deploy': False,
'profile': 'development-instances',
'provider': 'my-ec2-config',
'securitygroup': ['default'],
'size': 't1.micro',
'ssh_username': 'ec2_user'}]
Pretty cool right?
Extending Providers
-------------------
Some example usage on how to use ``extends`` within the cloud providers
configuration. Consider ``/etc/salt/salt/cloud.providers`` containing:
.. code-block:: yaml
my-develop-envs:
- id: HJGRYCILJLKJYG
key: 'kdjgfsgm;woormgl/aserigjksjdhasdfgn'
keyname: test
securitygroup: quick-start
private_key: /root/test.pem
location: ap-southeast-1
availability_zone: ap-southeast-1b
driver: ec2
- user: myuser@mycorp.com
password: mypass
ssh_key_name: mykey
ssh_key_file: '/etc/salt/ibm/mykey.pem'
location: Raleigh
driver: ibmsce
my-productions-envs:
- extends: my-develop-envs:ibmsce
user: my-production-user@mycorp.com
location: us-east-1
availability_zone: us-east-1
The above configuration, once parsed would generate the following providers
data:
.. code-block:: python
'providers': {
'my-develop-envs': [
{'availability_zone': 'ap-southeast-1b',
'id': 'HJGRYCILJLKJYG',
'key': 'kdjgfsgm;woormgl/aserigjksjdhasdfgn',
'keyname': 'test',
'location': 'ap-southeast-1',
'private_key': '/root/test.pem',
'driver': 'aws',
'securitygroup': 'quick-start'
},
{'location': 'Raleigh',
'password': 'mypass',
'driver': 'ibmsce',
'ssh_key_file': '/etc/salt/ibm/mykey.pem',
'ssh_key_name': 'mykey',
'user': 'myuser@mycorp.com'
}
],
'my-productions-envs': [
{'availability_zone': 'us-east-1',
'location': 'us-east-1',
'password': 'mypass',
'driver': 'ibmsce',
'ssh_key_file': '/etc/salt/ibm/mykey.pem',
'ssh_key_name': 'mykey',
'user': 'my-production-user@mycorp.com'
}
]
}
