Misconfiguration of Runner

ansible_runner.interface module

ansible_runner.interface.init_runner(**kwargs)[source]

This function will properly initialize both run() and run_async() functions in the same way and return a value instance of Runner.

See parameters given to ansible_runner.interface.run()

ansible_runner.interface.run(**kwargs)[source]

Run an Ansible Runner task in the foreground and return a Runner object when complete.

Parameters:
  • private_data_dir (str) – The directory containing all runner metadata needed to invoke the runner module. Output artifacts will also be stored here for later consumption.
  • ident (str) – The run identifier for this invocation of Runner. Will be used to create and name the artifact directory holding the results of the invocation.
  • json_mode (bool) – Store event data in place of stdout on the console and in the stdout file
  • playbook (str or filename or list) – The playbook (either supplied here as a list or string… or as a path relative to private_data_dir/project) that will be invoked by runner when executing Ansible.

Bases: object

A Runner configuration object that’s meant to encapsulate the configuration used by the ansible_runner.runner.Runner object to launch and manage the invocation of ansible and ansible-playbook

Typically this object is initialized for you when using the standard run interfaces in ansible_runner.interface but can be used to construct the Runner configuration to be invoked elsewhere. It can also be overridden to provide different functionality to the Runner object.

Example:
>>> rc = RunnerConfig(...)
>>> r = Runner(config=rc)
>>> r.run()
build_process_isolation_temp_dir()[source]

Create a temporary directory for process isolation to use.

generate_ansible_command()[source]

Given that the RunnerConfig preparation methods have been run to gather the inputs this method will generate the ansible or ansible-playbook command that will be used by the ansible_runner.runner.Runner object to start the process

prepare()[source]

Performs basic checks and then properly invokes

  • prepare_inventory
  • prepare_env
  • prepare_command

It’s also responsible for wrapping the command with the proper ssh agent invocation and setting early ANSIBLE_ environment variables.

prepare_command()[source]

Determines if the literal ansible or ansible-playbook commands are given and if not calls ansible_runner.runner_config.RunnerConfig.generate_ansible_command()

prepare_env()[source]

Manages reading environment metadata files under private_data_dir and merging/updating with existing values so the ansible_runner.runner.Runner object can read and use them easily

prepare_inventory()[source]

Prepares the inventory default under private_data_dir if it’s not overridden by the constructor.

wrap_args_with_cgexec(args)[source]

Wrap existing command line with cgexec in order to profile resource usage

wrap_args_with_process_isolation(args)[source]
Wrap existing command line with bwrap to restrict access to:
  • self.process_isolation_path (generally, /tmp) (except for own /tmp files)
wrap_args_with_ssh_agent(args, ssh_key_path, ssh_auth_sock=None, silence_ssh_add=False)[source]

Given an existing command line and parameterization this will return the same command line wrapped with the necessary calls to ssh-agent

ansible_runner.utils module

class ansible_runner.utils.Bunch(**kwargs)[source]

Bases: object

Collect a bunch of variables together in an object. This is a slight modification of Alex Martelli’s and Doug Hudgeon’s Bunch pattern.

update(**kwargs)[source]
class ansible_runner.utils.OutputEventFilter(handle, event_callback, suppress_ansible_output=False, output_json=False)[source]

Bases: object

File-like object that looks for encoded job events in stdout data.

close()[source]
flush()[source]
write(data)[source]
ansible_runner.utils.args2cmdline(*args)[source]
ansible_runner.utils.check_isolation_executable_installed(isolation_executable)[source]

ansible_runner.utils.cleanup_artifact_dir(path, num_keep=0)[source]
ansible_runner.utils.collect_new_events(event_path, old_events)[source]

Collect new events for the ‘events’ generator property

ansible_runner.utils.dump_artifact(obj, path, filename=None)[source]

Write the artifact to disk at the specified path

Args:
obj (string): The string object to be dumped to disk in the specified
path. The artifact filename will be automatically created

path (string): The full path to the artifacts data directory.

filename (string, optional): The name of file to write the artifact to.
If the filename is not provided, then one will be generated.
Returns:
string: The full path filename for the artifact that was generated

ansible_runner.utils.ensure_str(s, encoding='utf-8', errors='strict')[source]

Coerce s to str. For Python 2:

  • unicode -> encoded to str
  • str -> str
For Python 3:
  • str -> str
  • bytes -> decoded to str
ansible_runner.utils.isinventory(obj)[source]

Inspects the object and returns if it is an inventory

Args:
obj (object): The object to be inspected by this function
Returns:
boolean: True if the object is an inventory dict and False if it is not
ansible_runner.utils.isplaybook(obj)[source]

Inspects the object and returns if it is a playbook

Args:
obj (object): The object to be inspected by this function
Returns:
boolean: True if the object is a list and False if it is not
ansible_runner.utils.open_fifo_write(path, data)[source]

open_fifo_write opens the fifo named pipe in a new thread. This blocks the thread until an external process (such as ssh-agent) reads data from the pipe.
