Installation

Install from pip

If you have Python 3.6+ installed, you can run one of the following:

pip3 install pycons3rt3 python3 -m pip install pycons3rt3

Install from source

git clone https://github.com/cons3rt/pycons3rt3
cd pycons3rt3
python3 -m venv venv
source venv/bin/activate
python3 -m pip install build
python3 -m pip install .

Directories

When installed, pycons3rt determines and creates a system directory (pycons3rt_system_home) and a local user directory (pycons3rt_user_home).

The default locations for pycons3rt_system_home are here:

• Linux: ~/.cons3rt
• MacOS: ~/.cons3rt
• Windows: C:\cons3rt

The default locations for pycons3rt_user_home is: ~/.cons3rt on all OS types.

PYCONS3RT_HOME environment variable

To change the location of pycons3rt_system_home and pycons3rt_user_home, set the environment variable
PYCONS3RT_HOME to an existing directory. This directory will be used for both system and user home directories.

To do this on Linux or macOS, add the following to ~/.bash_profile:

export PYCONS3RT_HOME="/path/to/desired/directory"

On Windows, add the PYCONS3RT_HOME environment variable to the system settings.

The following directories are also created:

• Config: pycons3rt_system_home/conf/
• Logs: pycons3rt_user_home/log/
• Source: pycons3rt_user_home/src/

If installed from source via asset, the asset clones the pycons3rt source code here for installation:

• pycons3rt_user_home/src/pycons3rt

The logging configuration file is installed here:

• pycons3rt_system_home/conf/pycons3rt-logging.conf

By default, pycons3rt log files will output here:

• pycons3rt_user_home/log/pycons3rt-info.log
• pycons3rt_user_home/log/pycons3rt-warn.log
• pycons3rt_user_home/log/pycons3rt-debug.log

CONS3RT ReST API and CLI

pycons3rt3 provides a python3 SDK for using the CONS3RT ReST API.

To access the ReST API you will need:

• An active CONS3RT Account
• Access to a project
• A CONS3RT project-based ReST API token
• For sites that require Client Certificate Authentication you will need a valid PKI certificate (ECA)

pycons3rt3 does not support CAC authentication at this time

If you have an ECA certificate in p12 or pfx format, convert it to a password-less pem file:

openssl pkcs12 -in certfile.pfx -out certfile.pem -nodes

Configuration

To configure pycons3rt3 for the CONS3RT ReST API type:

cons3rt config

After entering your info, a config file is created here:

pycons3rt_user_home/conf/config.json

This configuration will automatically load for ReST API calls.

asset CLI

The asset CLI command helps you automatically create and import assets:

# Validate an asset structure
asset validate --asset_dir=/path/to/asset

# Create a valid asset zip file
asset create --asset_dir=/path/to/asset

• Creates an asset zip file AssetName.zip in your Downloads directory

Specify the destination directory:

asset create --asset_dir=/path/to/asset --dest_dir=/path/to/directory

• Creates an asset zip file AssetName.zip in the specified directory

Import an asset into CONS3RT:

asset import --asset_dir=/path/to/asset

• Creates an asset zip, and imports the zip file into CONS3RT
• Adds an asset.yml file to the asset directory with the site info and asset ID

Import an asset and set the visibility to the project-level:

asset import --asset_dir=/path/to/asset --visibility=OWNING_PROJECT

Update an existing asset in CONS3RT:

asset update --asset_dir=/path/to/asset

• Uses the asset ID in the asset.yml file
• Creates an asset zip, and updates the asset ID

Update an asset and set the visibility to the community-level:

asset update --asset_dir=/path/to/asset --visibility=COMMUNITY

Query for software assets:

asset query --asset_type=software

Query for the latest community container asset containing "nginx":

asset query --asset_type=containers --asset_subtype=DOCKER --expanded --community --name nginx --latest

Use the queryids command to query for just the latest asset ID for asset with name "nginx":

asset queryids --asset_type=containers --latest --name=nginx

cons3rt CLI

Usage:

cons3rt <command> <subcommands> <args>

Interactive command to create a config.json file:

cons3rt config

This creates a config file at the default location: ~/.cons3rt/conf/config.json

If PYCONS3RT_HOME environment variable is defined, config file location: ${PYCONS3RT_HOME}/conf/config.json

Specify a config file location:

cons3rt --config /path/to/config.json <command> <subcommands> <args>

Use pycons3rt3 in python

Logify

With the default configuration log files go to: pycons3rt_user_home/log/, and INFO level is printed to stdout. To customize pycons3rt logging, modify the logging configuration file.

Logging example:

import logging
from pycons3rt3.logify import Logify

mod_logger = Logify.get_name() + '.your_module'
    
    # Then use in a function or class:
    
    class MyClass(object):
        def __init__(self, dep=None):
            self.cls_logger = mod_logger + '.MyCLass'
    	def class_method(self):
    		log = logging.getLogger(self.cls_logger + '.class_method')
    		log.info('Class Method Logging')
    
    def main():
        log = logging.getLogger(mod_logger + '.main')
        log.debug('DEBUG')
    	log.info('INFO')
    	log.warn('WARN')
    	log.error('ERROR')

Deployment

This module provides a set of useful utilities for accessing deployment related info on deployment run hosts.

from pycons3rt3.deployment import Deployment
    
# Create a new Deployment object
dep = new Deployment()
    
# Deployment name
print(dep.deployment_name)
    
# Get the role name
print(dep.cons3rt_role_name)
    
# Deployment properties
print(dep.properties)
    
# Get a specific deployment property value by name
my_value = dep.get_value('cons3rt.user')
    
# Scenario network info
print(dep.scenario_network_info)

# ASSET_DIR
print(dep.asset_dir)

Slack

This module provides an interface for posting anything to Slack!

from pycons3rt3.slack import SlackMessage
from pycons3rt3.slack import SlackAttachments

# Create a message
slack_msg = SlackMessage(
                my_webhook_url, 
                channel='#DevOps', 
                icon_url='http://cool-icon-url',
                text='This is a Slack message',
                user='@sender_username')

# Create and add an attachment
slack_attachment = SlackAttachment(
                       fallback='This is the fallback text', 
                       color='green', 
                       pretext='Pretext', 
                       text='Moar text!')

slack_msg.add_attachment(slack_attachment)

# Send a message
slack_msg.send()

Nexus

This module provides simple method of fetching artifacts from a nexus repository.

from pycons3rt3 import nexus

nexus.get_artifact(
    username=nexus_username,
    password=nexus_password,
    suppress_status=True,
    nexus_url=nexus_url,
    timeout_sec=45,
    overwrite=False,
    group_id='com.cons3rt',
    artifact_id='cons3rt-backend-install',
    version=`18.11.1`,
    packaging='zip',
    classifier='package-otto',
    destination_dir=dest_dir)

Bash (Linux only)

Executes commands on a Linux system. See the source code for specific available commands but the most commonly used run_command is shown below.

run_command(command, timeout_sec=3600.0, output=True)

Parameters

• command: List containing the command and any additional args
• timeout_sec: (optional) Float specifying how long to wait before terminating the command. Default is 3600.0.
• output: (boolean) True collects the output of the command. In some cases suppressing the command output improves stability.

Returns:

• A dictionary containing "code", the numeric exit code from the command, and "output" which captures the stdout/strerrif output was set True. Sample output:

Raises: CommandError when there is a problem running the command.

{
    "code": "0",
    "output": "stdout/stderr from the command"
}

Example Usage:

from pycons3rt3.bash import run_command
from pycons3rt3.bash import CommandError
command = ['ls', '/root']
try:
    result = run_command(command, timeout_sec=60.0)
    code = result['code']
    output = result['output']
except CommandError:
    raise
if code == 0:
    log.info('Successfully executed command {c}'.format(s=command))
else:
    msg = 'There was a problem running command returned code {c} and produced output: {o}'.format(
                    c=code, o=output)
            log.error(msg)
            raise CommandError(msg)
