If you have Python 2.7 installed, you can run:
pip install pycons3rt
Also you can install specific versions:
pip install pycons3rt==0.0.2
git clone https://github.com/cons3rt/pycons3rt
cd pycons3rt
python setup.py
Search for community pycons3rt
software assets in HmC or cons3rt.com to use.
To create your own pycons3rt assets, from the pycons3rt repo root directory, run:
$ ./scripts/make-assets.sh
This will create your own Linux and Windows pycons3rt assets for import:
./build/asset-pycons3rt-linux.zip
./build/asset-pycons3rt-windows.zip
Once installed, run the following command to set up pycons3rt:
pycons3rt_setup
- Git
- Python 2.7.x
- pip
- 0 - Success
- Non-zero - See log file in /var/log/cons3rt/ for additional details
- 0 - Success
- 1 - Asset install failed:
- pycons3rt install script not found, git clone may not have succeeded
- There was a problem setting up pycons3rt
- pycons3rt osutil not found
- There was a problem running osutil
When installed, pycons3rt creates a system directory (pycons3rt_system_home
) and
a local user directory (pycons3rt_user_home
).
The pycons3rt_system_home
directory is located on your system here:
- Linux:
/etc/pycons3rt
- MacOS:
~/.pycons3rt
- Windows:
C:\pycons3rt
The pycons3rt_user_home
directory is here on all OS types:
~/.pycons3rt
The following assets are also created:
- System pycons3rt config dir:
pycons3rt_system_home/conf/
- User log dir (default):
pycons3rt_user_home/log/
- Pycons3rt source dir:
pycons3rt_user_home/src/
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
With the default configuration log files go to: ~/.pycons3rt/log/
, and INFO
level is printed to stdout. To customize pycons3rt logging, modify the
pycons3rt-logging.conf
file.
import logging
from pycons3rt.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')
This module provides a set of useful utilities for accessing CONS3RT deployment related info. It is intended to be imported and used in other python-based CONS3RT assets.
from pycons3rt.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)
This module provides an interface for posting anything to Slack!
from pycons3rt.slack import SlackMessage
from pycons3rt.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()
This module provides simple method of fetching artifacts from a nexus repository.
from pycons3rt 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)
Executes commands on a Linux system. See the source code for specific available
commands but the most commonly used run_command
is shown below.
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 supressing 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 pycons3rt.bash import run_command
from pycons3rt.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)
