The Resilient Python Client (resilient module) contains tools helpful in calling
the Resilient REST API and Action Module.
It provides a SimpleClient class that you use to call the Resilient REST API. This class manages an authenticated connection to the Resilient server, and simple helper methods for accessing REST resources.
The module also provides an ArgumentParser (which extends argparse.ArgumentParser)
to simplify the writing of command line utilities. This provides support for
standard arguments such as --host and --email that Resilient-oriented
command line tools will generally need. The ArgumentParser can read defaults
from a configuration file, and override them from the command line.
Configuration parameters for the server URLs, user credentials and so on should be provided using a configuration file. They can optionally also be provided on the command-line.
If the environment variable APP_CONFIG_FILE is set, it defines the path
to your configuration file. The default location for this file is
app.config in a directory named .resilient under the user's home directory.
The configuration file is a text file, with a [resilient] section containing:
[resilient]
host=resilient.example.com
port=443
email=api@example.com
password=passw0rd
org=Culture
Configuration Values From Keystore
Values in the config file can be pulled from a compatible keystore system
on your OS. To retrieve a value named yourkey from a keystore, set it to ^yourkey.
Example from app.confg:
[resilient]
password=^resilient_password
Adding the Values to Keystore
The resilient package includes a utility to add all of the keystore-based values from
your app.config file to your system's compatible keystore system. Once you have
referenced the keys in your app.config file, run res-keyring and you will be
prompted for the secure values to store.
$ res-keyring
Configuration file: /Users/example/.resilient/app.config
Secrets are stored with 'keyring.backends.OS_X'
[resilient] password: <not set>
Enter new value (or <ENTER> to leave unchanged):
Configuration Values From Environment
Values in your config file can also be pulled from environment variables.
To retrieve a value from the environment, set it to $YOUR_ENV_VAR.
Example from app.confg:
[resilient]
password=$resilient_password
A standard way to initialize a SimpleClient with this configuration is,
# Read the standard Resilient APIs configuration file
# - default location is ~/.resilient/app.config
# - or the location set in $APP_CONFIG_FILE
# and any other arguments specified on the command line
parser = resilient.ArgumentParser(config_file=resilient.get_config_file())
opts = parser.parse_args()
# Initialize a SimpleClient with these options
client = resilient.get_client(opts)
Current versions of the release package are available on
PyPi and
GitHub.
Install using pip:
pip install resilient
If you have downloaded a package file, install it using pip
(the filename will vary according to the current version of this repository):
pip install resilient-x.x.x.tar.gz
You can build release package files locally, by
bash ./buildall.sh <version_number>
where <version_number> is a full version number ("29.0.123", etc).
The resilient package includes command-line utilities:
res-keyring, described above.finfo, to read and display metadata about the fields in your Resilient organization.gadget, for general-purpose command line access to Resilient REST API.
The Resilient-Circuits Application Framework (resilient_circuits module)
is a lightweight framework for rapid development of Resilient Action Module
event processors in Python.
It provides an extensible "application" class that loads any Python files
in the application's components directory as well as any installed
compatible packages. For each of these components, it automatically subscribes
to the appropriate Action Module message destination (queue or topic), and
dispatches messages to the relevant method.
The framework manages the connection to the Action Module, including any reconnection after a network outage. It also manages acknowledgement of action messages and sending action status back to the server.
To develop a component, you simply subclass the ResilientComponent class.
This superclass includes several utility functions that provide convenient
access to the REST API and action message data.
Current versions of the release package are available on
PyPi and
GitHub.
Install using pip:
pip install resilient-circuits
If you have downloaded a package file, install it using pip
(the filename will vary according to the current version of this repository):
pip install resilient_circuits-x.x.x.tar.gz
In order to connect to the Resilient server, if the server
doesn't have a trusted TLS certificate, you must provide the server's
certificate in a file (e.g. "cacerts.pem"). The quickest way to do this
is to use either openssl or the Java keytool command line utilities.
Using openssl to create the cacerts.pem file (using Linux or Mac OS):
openssl s_client -connect SERVER:443 -showcerts -tls1 < /dev/null > cacerts.pem 2> /dev/null
Using keytool to create the cacerts.pem file (Linux, Mac OS or Windows):
keytool -printcert -rfc -sslserver SERVER:443 > cacerts.pem
WARNING: In a production setting, you should take care to get the certificate from a trusted source and confirm its fingerprint.
When connecting to a Resilient server with the Python libraries, the hostname you specify must match exactly the name in the server certificate. If there is a mismatch, the permanent solution is to either change your DNS server or change the server certificate so it matches. It is also possible to modify your 'hosts' file temporarily, but that is not a permanent solution.
