The commands must be the exact same commands as found in the device running-config. Be sure to note the configuration command syntanx as some commands are automatically modified by the device config parser. required: true before: description: - The ordered set of commands to push on to the command stack if a change needs to be made. This allows the playbook designer the opportunity to perform configuration commands prior to pushing any changes without affecting how the set of commands are matched against the system required: false default: null after: description: - The ordered set of commands to append to the end of the command stack if a changed needs to be made. Just like with I(before) this allows the playbook designer to append a set of commands to be executed after the command set. required: false default: null match: description: - Instructs the module on the way to perform the matching of the set of commands against the current device config. If match is set to I(line), commands are matched line by line. If match is set to I(strict), command lines are matched with respect to position. Finally if match is set to I(exact), command lines must be an equal match. required: false default: line choices: ['line', 'strict', 'exact'] replace: description: - Instructs the module on the way to perform the configuration on the device. If the replace argument is set to I(line) then the modified lines are pushed to the device in configuration mode. If the replace argument is set to I(block) then the entire command block is pushed to the device in configuration mode if any line is not correct required: false default: line choices: ['line', 'block'] force: description: - The force argument instructs the module to not consider the current devices running-config. When set to true, this will cause the module to push the contents of I(src) into the device without first checking if already configured. required: false default: false choices: ['yes', 'no'] config: description: - The module, by default, will connect to the remote device and retrieve the current running-config to use as a base for comparing against the contents of source. There are times when it is not desirable to have the task get the current running-config for every task in a playbook. The I(config) argument allows the implementer to pass in the configuruation to use as the base config for comparision. required: false default: null """ EXAMPLES = """ - asa_acl: lines: - access-list ACL-ANSIBLE extended permit tcp any any eq 82 - access-list ACL-ANSIBLE extended permit tcp any any eq www - access-list ACL-ANSIBLE extended permit tcp any any eq 97 - access-list ACL-ANSIBLE extended permit tcp any any eq 98 - access-list ACL-ANSIBLE extended permit tcp any any eq 99 before: clear configure access-list ACL-ANSIBLE match: strict replace: block - asa_acl: lines: - access-list ACL-OUTSIDE extended permit tcp any any eq www - access-list ACL-OUTSIDE extended permit tcp any any eq https context: customer_a """ RETURN = """ updates: description: The set of commands that will be pushed to the remote device returned: always type: list sample: ['...', '...'] responses: description: The set of responses from issuing the commands on the device retured: when not check_mode type: list sample: ['...', '...'] """ def get_config(module): config = module.params['config'] or dict() if not config and not module.params['force']: config = module.config return config def check_input_acl(lines, module): first_line = True for line in lines: ace = line.split() if ace[0] != 'access-list': module.fail_json(msg='All lines/commands must begin with "access-list" %s is not permitted' % ace[0]) if len(ace) <= 1: module.fail_json(msg='All lines/commainds must contain the name of the access-list') if first_line: acl_name = ace[1] else: if acl_name != ace[1]: module.fail_json(msg='All lines/commands must use the same access-list %s is not %s' % (ace[1], acl_name)) first_line = False return 'access-list %s' % acl_name def main(): argument_spec = dict( lines=dict(aliases=['commands'], required=True, type='list'), before=dict(type='list'), after=dict(type='list'), match=dict(default='line', choices=['line', 'strict', 'exact']), replace=dict(default='line', choices=['line', 'block']), force=dict(default=False, type='bool'), config=dict() ) module = get_module(argument_spec=argument_spec, supports_check_mode=True) lines = module.params['lines'] before = module.params['before'] after = module.params['after'] match = module.params['match'] replace = module.params['replace'] module.filter = check_input_acl(lines, module) if not module.params['force']: contents = get_config(module) config = NetworkConfig(contents=contents, indent=1) candidate = NetworkConfig(indent=1) candidate.add(lines) commands = candidate.difference(config, match=match, replace=replace) else: commands = [] commands.extend(lines) result = dict(changed=False) if commands: if before: commands[:0] = before if after: commands.extend(after) if not module.check_mode: commands = [str(c).strip() for c in commands] response = module.configure(commands) result['responses'] = response result['changed'] = True result['updates'] = commands module.exit_json(**result) from ansible.module_utils.basic import * from ansible.module_utils.shell import * from ansible.module_utils.netcfg import * from ansible.module_utils.asa import * if __name__ == '__main__': main()
