ansible-dynamic-launcher

When you want to run roles on a dynamic range of hosts, use this - it passes through commands and hooks into ansible.cfg

Simply download this as a submodule and run it (Might need to check deps).

Download options

• clone this repo as a submodule
• build_packages.sh and install with dpkg
• wget -O ansible-dynamic-launcher.py https://raw.githubusercontent.com/AlexsJones/ansible-dynamic-launcher/master/executor.py
• curl -o ansible-dynamic-launcher.py https://raw.githubusercontent.com/AlexsJones/ansible-dynamic-launcher/master/executor.py

Example

python executor.py --range 192.168.1-20 --module shell --args 'ls -la' --workingdir ../

Or run a playbook

python executor.py --name 'boot.yml' --range 10.0.0.1-40 --workingdir ../ --args "role=clean_disk"

Note you can make far more complex range scans by just editing the nmap args in the config.

Configuration

Usage: executor.py [options]

Options:
  -h, --help            show this help message and exit
  -m MODULE, --module=MODULE
                        Name of ansible module to run
  -a ARGS, --args=ARGS  Argument of module running
  -r RANGE, --range=RANGE
                        an nmap friendly host range to scan e.g. 127.0.0.1-100
  -n NAME, --name=NAME  name of the playbook to run e.g. boot.yml
  -w WORKINGDIR, --workingdir=WORKINGDIR
                        working dir with ansible.cfg in the root

As long as the --workingdir points to your ansible.cfg directory and --name is the name (not path) of your playbook yml in that file, you're ready to go...

And add this to your ansible.cfg

scan_args='-sP'  #nmap arguments
syntax=False
private_key_file= #required for passwordless SSH
