21 | Environment | A JSON dictionary representing a Chef Environment object. If the VNF action requires loading or modifying Chef environment attributes associated with the VNF, all the relevant information must be provided in this JSON dictionary in a structure that conforms to a Chef Environment Object. | Optional | Depends on VNF action. |
22 +-------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------+-----------------------------------------------------------------------------------------------------------------------------------------+
23 | Node | A JSON dictionary representing a Chef Node Object. | Mandatory | |
25 | | The Node JSON dictionary must include the run list to be triggered for the desired VNF action by the push job. It should also include any attributes that need to be configured on the Node Object as part of the VNF action. | | |
26 +-------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------+-----------------------------------------------------------------------------------------------------------------------------------------+
27 | NodeList | Array of FQDNs that correspond to the endpoints (VMs) of a VNF registered with the Chef Server that need to trigger a chef-client run as part of the desired VNF action. | Mandatory | |
28 +-------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------+-----------------------------------------------------------------------------------------------------------------------------------------+
29 | PushJobFlag | This field indicates whether the VNF action requires a push Job. Push job object will be created by ONAP if required. | Mandatory | If set to “True”, ONAP will request a push job. Ignored otherwise. |
30 +-------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------+-----------------------------------------------------------------------------------------------------------------------------------------+
31 | CallbackCapable | This field indicates if the chef-client run invoked by push job corresponding to the VNF action is capable of posting results on a callback URL. | Optional | If Chef cookbook is callback capable, VNF owner is required to set it to “True”. Ignored otherwise. |
32 +-------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------+-----------------------------------------------------------------------------------------------------------------------------------------+
33 | GetOutputFlag | Flag which indicates whether ONAP should retrieve output generated in a chef-client run from Node object attribute node[‘PushJobOutput’] for this VNF action (e.g., in Audit). | Mandatory | ONAP will retrieve output from NodeObject attributes [‘PushJobOutput’] for all nodes in NodeList if set to “True”. Ignored otherwise. |

36 Chef Template example:
42 "description": "VNF Chef environment for HAR",
43 "json\_class": "Chef::Environment",
44 "chef\_type": "environment",
45 "default\_attributes": { },
46 "override\_attributes": {
49 “Database\_IP”:”10.10.1.5”
54 “name” : “signal.network.com “
56 "json\_class": "Chef::Node",
58 “IPAddress1”: “192.168.1.2”,
59 “IPAddress2”:”135.16.162.5”,
66 “chef\_environment” : “\_default”
67 "run\_list": [ "configure\_signal" ]
69 “NodeList”:[“node1.vnf\_a.onap.com”, “node2.vnf\_a.onap.com”],
71 “CallbackCapable”:True
72 “GetOutputFlag” : “False”
75 The example JSON file provided by the VNF provider for each VNF action will be
76 turned into a template by ONAP, that can be updated with instance
77 specific values at run-time.
79 Some points worth noting regarding the JSON fields:
81 a. The JSON file must be created for each action for each VNF.
83 b. If a VNF action involves multiple endpoints (VMs) of a VNF, ONAP will
84 replicate the “Node” JSON dictionary in the template and post it to
85 each FQDN (i.e., endpoint) in the NodeList after setting the “name”
86 field in the Node object to be the respective FQDN [1]_. Hence, it
87 is required that all end points (VMs) of a VNF involved in a VNF
88 action support the same set of Node Object attributes.
90 The following table describes the JSON dictionary to post in Callback.

275 1. Entitlement and License Key Limits
277 Limitations on the use of software entitlements and license keys may be
278 based on factors such as: features enabled in the product, the allowed
279 capacity of the product, number of installations, etc... The limits may
280 generally be categorized as:
292 Multiple limits may be applicable for an entitlement or license key.
293 Each limit may further be described by limit behavior, duration,
294 quantification, aggregation, aggregation interval, start date, end date,
297 When the limit is associated with a quantity, the quantity is relative
298 to an instance of the entitlement or license key. For example:
300 - Each entitlement grants the right to 50 concurrent users. If 10
301 entitlements are purchased, the total number of concurrent users
302 permitted would be 500. In this example, the limit category is
303 **amount**, the limit type is **users**, and the limit
304 **quantification** is **50.**
306 Each license key may be installed on 3 devices. If 5 license keys are
307 acquired, the total number of devices allowed would be 15. In this
308 example, the limit category is **usages**, the limit type is
309 **device**, and the limit **quantification** is **3.**
313 Locations may be logical or physical location (e.g., site, country). For
316 - use is allowed in Canada

1494 R-99771: The VNF **MUST** provide all code/configuration files in a “Locked down” or hardened state or with documented recommendations for such hardening. All unnecessary services will be disabled. VNF provider default credentials, community strings and other such artifacts will be removed or disclosed so that they can be modified or removed during provisioning.
1496 R-58358: The VNF **MUST** implement the **:with-defaults** capability [RFC6243].

1500 R-84879: The VNF **MUST** have the capability of maintaining a primary and backup DNS name (URL) for connecting to ONAP collectors, with the ability to switch between addresses based on conditions defined by policy such as time-outs, and buffering to store messages until they can be delivered. At its discretion, the service provider may choose to populate only one collector address for a VNF. In this case, the network will promptly resolve connectivity problems caused by a collector or network failure transparently to the VNF.
1502 R-06413: The VNF **MUST** log the field “service or program used for access” in the security audit logs.
1504 R-51442: The VNF **SHOULD** use playbooks that are designed to automatically ‘rollback’ to the original state in case of any errors for actions that change state of the VNF (e.g., configure).
1506 R-98989: The VNF **SHOULD** utilize resource pooling (threads, connections, etc.) within the VNF application so that resources are not being created and destroyed resulting in resource management overhead.

1520 R-14025: The VNF **MUST** provide or support the Identity and Access Management (IDAM) based threat detection data for Session Hijacking.
1522 R-86835: The VNF **MUST** set the default settings for user access to sensitive commands and data to deny authorization.
1524 R-73583: The VNF **MUST** allow changes of configuration parameters to be consumed by the VNF without requiring the VNF or its sub-components to be bounced so that the VNF availability is not effected.
1526 R-73223: The VNF **MUST** support proactive monitoring to detect and report the attacks on resources so that the VNFs and associated VMs can be isolated, such as detection techniques for resource exhaustion, namely OS resource attacks, CPU attacks, consumption of kernel memory, local storage attacks.
1528 R-06668: The VNF **MUST** handle the start or restart of VNFC instances in any order with each VNFC instance establishing or re-establishing required connections or relationships with other VNFC instances and/or VNFs required to perform the VNF function/role without requiring VNFC instance(s) to be started/restarted in a particular order.
1530 R-41215: The VNF **MAY** have zero to many “incremental” modules.
1532 R-85991: The VNF provider **MUST** provide a universal license key per VNF to be used as needed by services (i.e., not tied to a VM instance) as the recommended solution. The VNF provider may provide pools of Unique VNF License Keys, where there is a unique key for each VNF instance as an alternate solution. Licensing issues should be resolved without interrupting in-service VNFs.
1534 R-52085: The VNF **MUST**, if not using the NCSP’s IDAM API, provide the ability to support Multi-Factor Authentication (e.g., 1st factor = Software token on device (RSA SecureID); 2nd factor = User Name+Password, etc.) for the users.
1536 R-29495: The VNF **MUST** support locking if a common object is being manipulated by two simultaneous NETCONF configuration operations on the same VNF within the context of the same writable running data store (e.g., if an interface parameter is being configured then it should be locked out for configuration by a simultaneous configuration operation on that same interface parameter).
1538 R-31751: The VNF **MUST** subject VNF provider VNF access to privilege reconciliation tools to prevent access creep and ensure correct enforcement of access policies.
1540 R-48698: The VNF **MUST** utilize information from key value pairs that will be provided by the Ansible Server as extra-vars during invocation to execute the desired VNF action. If the playbook requires files, they must also be supplied using the methodology detailed in the Ansible Server API.

1552 R-49945: The VNF **MUST** authorize VNF provider access through a client application API by the client application owner and the resource owner of the VNF before provisioning authorization through Role Based Access Control (RBAC), Attribute Based Access Control (ABAC), or other policy based mechanism.
1554 R-20912: The VNF **MUST** support alternative monitoring capabilities when VNFs do not expose data or control traffic or use proprietary and optimized protocols for inter VNF communication.
1557 Ansible Playbook Examples
1558 -----------------------------------------------
1560 The following sections contain examples of Ansible playbook contents
1561 which follow the guidelines.
1563 Guidelines for Playbooks to properly integrate with APPC
1564 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1566 NOTE: To support concurrent requests to multiple VNF instances of same
1567 or different type, VNF hosts and other files with VNF specific default
1568 values are kept or created in separate directories.
1570 Example of an Ansible command (after pwd) to run playbook again
1571 vfdb9904v VNF instance:
1573 .. code-block:: none
1576 /storage/vfdb/V16.1/ansible/configure
1577 $ ansible-playbook -i ../inventory/vfdb9904v/hosts site.yml --extra-vars "vnf_instance=vfdb9904v"
1579 Example of corresponding APPC API Call from ONAP – Ansible Server
1582 An example POST for requesting execution of configure Playbook:
1584 .. code-block:: none
1586 {"Id": "10", "PlaybookName":
1587 "/storage/vfdb/latest/ansible/configure/site.yml", "NodeList":
1588 ["vfdb9904v"], "Timeout": 60, "EnvParameters": {"Retry": 3, "Wait": 5},
1589 "LocalParameters": {"vfdb9904v": {"T_true": 10, "T_false": 5,
1594 - An ID number is assigned to each request. This ID number is used to
1595 track request down to completion and provide status to APPC when
1598 - Playbook Name provided in the request (full path in this case)
1600 - Playbook path (in this example provided as part of playbook name as
1601 full path) or, later in a separate variable, playbook root directory
1602 needs to be part of APPC template.
1604 Ansible Playbooks will use the VNF instance name (passed using
1605 --extra-vars "vnf\_instance=vfdb9904v") to identify other default values
1606 to run the playbook(s) against the target VNF instance. Same example as
1609 .. code-block:: none
1611 $ ansible-playbook -i ../inventory/vfdb9904v/hosts site.yml --extra-vars "vnf_instance=vfdb9904v"
1613 SSH key info (name/path), used to authenticate with the VNF VMs, is one
1614 of the attributes stored in the Ansible Server inventory hosts file for
1615 the VNF instance and later will be passed down by APPC, in the inventory
1616 hosts file, to the Ansible Server as part of the request. Here hosts
1617 file to run ansible-playbook listed in this example above (IP addresses
1620 .. code-block:: none
1622 $ more ../inventory/vfdb9904v/hosts
1624 localhost ansible_connection=local
1627 1xx.2yy.zzz.109 ansible_ssh_private_key_file=/storage/.ssh/Kilo-SSH-Key.pem
1628 1xx.2yy.zzz.110 ansible_ssh_private_key_file=/storage/.ssh/Kilo-SSH-Key.pem
1631 1xx.2yy.zzz.105 ansible_ssh_private_key_file=/storage/.ssh/Kilo-SSH-Key.pem
1632 1xx.2yy.zzz.106 ansible_ssh_private_key_file=/storage/.ssh/Kilo-SSH-Key.pem
1634 NOTE: APPC requests to run Playbooks/Cookbooks are specific to a VNF,
1635 but could be more limited to one VM or one type of VM by the request
1636 parameters. Actions that may impact a site (LCP), a service, or an
1637 entire platform must be orchestrated by MSO in order to execute requests
1638 via APPC which then invoke VNF level playbooks. Playbooks that impact
1639 more than a single VNF are not the current focus of these guidelines.
1641 And here the scrubbed default arguments for this VNF instance:
1643 .. code-block:: none
1645 vnf_instance=vfdb9904v
1647 $ more ../vars/vfdb9904v/default_args.yml
1648 vnf_provider_network_network: d69fea03-xxx-yyy-zzz-nnnnnnnnnnnn
1649 vnf_provider_network_subnet: a07f6a3d-xxxx-yyy-zzz-ssssssssssss
1650 vm_config_oam_vnfc_name: vfdb9904vm001oam001
1651 vm_config_oam_hostname: vfdb9904vm001
1652 vm_config_oam_provider_ip_address: 1xx.2yy.zzz.109
1655 IMPORTANT: The APPC and default file attribute name for
1656 vm\_config\_oam\_vnfc\_name, as an example, is derived from vm\_config
1657 array structure (list) in the CSAR package ENV file, with dots replaced
1660 .. code-block:: none
1664 oam: {vnfc_name: {{ vm_config_oam_vnfc_name }}, hostname: {{
1665 vm_config_oam_hostname }}, provider_ip_address: {{
1666 vm_config_oam_provider_ip_address }
1670 Parameters like VNF names, VNFC names, OA&M IP addresses, after
1671 February, 2018 ONAP release, will be extracted from A&AI by APPC and
1672 then passed down to Ansible Server, as part of APPC request through REST
1673 API. In the meantime, these VNF instance specific required values, will
1674 be stored on VNF instance directory, default arguments file and will be
1675 used as defaults. For parameterized playbooks attribute-value pairs
1676 passed down by APPC to Ansible Server always take precedence over
1677 template or VNF instance specific defaults stored in defaults file(s).
1679 .. code-block:: none

1708 vm_config_rdb4_provider_ip_address: 1xx.2yy.zzz.yyy
1710 One of the first tasks on the Ansible Playbooks is to combine the VNF
1711 type generic template, derived from ENV files in CSAR or other files,
1712 with these default values stored on the Ansible Server, together with
1713 the overriding parameters passed down from APPC, to create the VNF
1714 instance specific set of attribute-value pairs to be used for the run in
1715 YAML format. Here is an excerpt from such a file that should look
1716 somewhat similar to ENV files:
1718 .. code-block:: none

1751 NOTE: Arguments passed by APPC to Ansible Server to run a playbook take
1752 precedence over any defaults stored in Ansible Server.
1754 Ansible Playbooks – Notes On Artifacts Required to Run Playbooks
1755 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1757 Inventory hosts file: should be VNF instance specific.
1759 Default variables: should be VNF instance specific/
1761 NOTE: Some playbooks may rely on inventory directory contents to target
1762 the collection of VNFs in the Services Platform supported through
1765 Playbooks and paths to referenced files: Playbooks shall not use
1766 absolute paths for file include entries (variables or playbooks) or
1767 other types of references.
1769 For this to work properly when running playbooks, the directory where
1770 the playbook resides shall be the current directory.
1772 Playbook includes use paths relative to the main playbook directory when
1775 Root directory named ansible - Any files provided with playbooks,
1776 included or referenced by playbooks, shall reside under the ansible
1777 playbooks (root) directory, containing all playbook subdirectories, or
1778 below that ansible root directory, in other subdirectories to support
1779 on-boarding and portability of VNF collection of playbooks and related
1782 Designing for a shared environment, concurrently running playbooks,
1783 targeting multiple VNF instances – inventory hosts file:
1785 To avoid inventory hosts file overwrites or collisions between multiple
1786 concurrently running VNF instance requests, chosen approach is for each
1787 VNF instance hosts file, to be stored under the Ansible Server Playbooks
1788 root directory, under the inventory subdirectory, and under a directory
1789 for each VNF instance, named after the VNF instance, as follows:
1791 ansible/inventory/<VNF\_instance\_name>/hosts
1793 Example of inventory hosts file path, relative to ansible playbooks root
1794 directory (playbooks\_dir): ansible/inventory/vnfx0001v/hosts
1796 Designing for a shared environment, concurrently running playbooks,
1797 targeting multiple VNF instances – default argument variables for
1798 specific VNF instances:
1800 Files containing attribute name value pairs (variable name and default
1801 values), referenced/included by playbooks – Files containing VNF
1802 instance specific default values – in a later APPC release, some or all
1803 the default attribute value pairs contained in the defaults file, may be
1804 passed down by APPC, to the Ansible Server, overriding these defaults:
1806 Following the same approach for inventory hosts files, files
1807 referenced/included by playbooks containing default values,
1808 default\_args.yml, shall be stored under a directory with VNF instance
1813 ansible/vars/<VNF\_instance\_name>/default\_args.yml
1815 Files containing attribute name value pairs (variable name and default
1816 values), referenced/included by playbooks – created dynamically by
1819 Following the same approach for inventory hosts files, to avoid
1820 overwrites or collisions of multiple concurrently running VNF instance
1821 requests, files created dynamically by playbooks, based on VNF generic
1822 templates, combined with default values and arguments passed down by
1823 APPC (as part of the request), shall be stored under a directory with
1824 VNF instance name on the path.
1828 tmp/<VNF\_instance\_name>/all.yml
1830 Files containing site specific (Openstack location non-instance
1831 specific) attribute name value pairs, like NTP server and DNS server’s
1832 IP addresses and other parameters, referenced/included by playbooks, not
1833 VNF specific – Could/should be stored under vars directory, in a
1834 subdirectory named after the string used to identify the site (nyc1,

1845 \ **Ansible Server Design - Directory Structure**
1847 To help understanding the contents of this section, here are few basic
1850 **VNF type a.k.a VNF Function Code** - Based on current Services
1851 Platform naming convention, each Virtual Network Function is assigned a
1852 4 character string (example vfdb), they are the first 4 characters on
1853 the VNF instance name, which is 9 characters long. VNF instance name in
1854 some cases corresponds to the stack name for the VNF when VNF instance
1855 is built based on a single module, single stack. Example of VNF instance
1856 name: vfdb9904v. All VNF performing this function, running the same
1857 software, coming from the same VNF provider will start with the same 4
1858 characters, in this example, vfdb.
1860 VNF type, determined through these 4 characters, is also known as VNF
1861 Function Code and is assigned by inventory team. All Services Platform
1862 VNF Function Codes can be found in inventory database and/or A&AI as
1863 well as Services Platform Network Design Documents.
1865 NOTE: Current Services Platform naming convention is undergoing changes
1866 to include geographical location to the VNF names.
1868 Version – As in VNF software version is the release of the software
1869 running on the VNF for which the playbooks were developed. VNF
1870 configuration steps may change from release to release and this
1871 <Version> in the path will allow the Ansible Server to host playbooks
1872 associated with each software release. And run the playbooks that match
1873 the software release running on each VNF instance. APPC initially will
1874 not support playbook versioning only latest playbook is supported.
1876 Playbook Function - Is a name associated with a life cycle management
1877 task(s) performed by the playbook(s) stored in this directory. It should
1878 clearly identify the type of action(s) performed by the main playbook
1879 and possibly other playbooks stored in this same directory. Ideally,
1880 playbook function would match APPC corresponding function that executes
1881 the main playbook in this directory. Following Ansible Naming standards
1882 main playbook is usually named site.yml. There can be other playbooks on
1883 the same directory that use a subset of the roles used by the main
1884 playbook site.yml. Examples of Playbook Function directory names:
1886 - configure – Contains post-instantiation (bulk) configuration
1889 - healthcheck – Contains VNF health check playbook(s), roles,…
1891 - stop – Contains VNF application stop playbook(s), roles,…
1893 - start – Contains VNF application start playbook(s), roles,…
1895 Directory structure to allow hosting multiple version sets of playbooks,
1896 for the same VNF type, to be hosted in the runtime environment on the
1897 Ansible Servers. Generic directory structure:
1899 Ansible Playbooks – Function directory and main playbook:
1901 .. code-block:: none
1903 /storage/<VNF type>/<Version>/ansible/<Playbook Function>/site.yml
1905 Example – Post-instantiation (bulk) configuration –APPC Function -
1908 .. code-block:: none
1910 /storage/<VNF type>/<Version>/ansible/configure/site.yml
1912 Example – Health-check –APPC Function - HealthCheck:
1914 .. code-block:: none
1916 /storage/<VNF type>/<Version>/ansible/healthcheck/site.yml
1918 OR (Function directory name does not need to match APPC function name)
1920 .. code-block:: none
1922 /storage/<VNF type>/<Version>/ansible/check/site.yml
1924 Ansible Directories for other artifacts – VNF inventory hosts file -
1927 .. code-block:: none
1929 /storage/<VNF type>/<Version>/ansible/inventory/<VNF instance name>/hosts
1931 Ansible Directories for other artifacts – VNF inventory hosts file –
1934 .. code-block:: none
1936 /storage/<VNF type>/<Version>/ansible/vars/<VNF instance name>/default\_args.yml
1938 NOTE: This requirement is expected to be deprecated in part in the
1939 future, for automated actions, once APPC can pass down all VNF specific
1940 arguments for each action. Requirement remains while manual actions are
1941 to be supported. Other automated inventory management mechanisms may be
1942 considered in the future, Ansible supports many automated inventory
1943 management mechanisms/tools/solutions.
1945 Ansible Directories for other artifacts – VNF (special) groups –
1948 .. code-block:: none
1950 /storage/<VNF type>/<Version>/ansible/groups/<VNF instance name>/common\_groups.yml
1952 NOTE: Default groups will be created based on VNFC type, 3 characters,
1953 on VNFC name. Example: “oam”, “rdb”, “dbs”, “man”, “iox”, “app”,…
1955 Ansible Directories for other artifacts – VNF (special) other files –
1956 Optional – Example – License file:
1958 .. code-block:: none
1960 /storage/<VNF type>/<Version>/ansible/<Other directory(s)>
1962 CAUTION: On referenced files used/required by playbooks.
1964 - To avoid missing files, during on-boarding or uploading of Ansible
1965 Playbooks and related artifacts, all permanent files (not generated
1966 by playbooks as part of execution), required to run any playbook,
1967 shall reside under the ansible root directory or below on other
1970 - Any references to files, on includes or other playbook entries, shall
1973 - This is the ansible (root directory) directory referenced on this
1976 .. code-block:: none
1978 /storage/<VNF type>/<Version>/ansible/
1980 There will be a soft link to the latest set of Ansible Playbooks for
1981 each VNF type and this is the default set of playbooks that are executed
1982 unless a different release is specified in APPC request.
1984 VNF type directories use A&AI inventory VNF function code. Ansible
1985 Playbooks will be stored on a Cinder Volume mounted on the Ansible
1986 Servers as /storage. Example:
1988 /storage/vfdb/latest/ansible – This soft link point to the latest set of
1989 playbooks (or the only set)
1991 /storage/vfdb/V16.1/ansible – Root directory for database VNF Ansible
1992 Playbooks for release 16.1
1994 CAUTION: To support this directory structure as the repository to store
1995 Ansible Playbooks run by APPC, APPC API in the Ansible Server side needs
1996 to be configured to run playbooks from directory, not MySQL database.
1998 Ansible Server HTTP will be configured to support APPC REST API requests
1999 to run playbooks as needed, against specific VNF instances, or specific
2000 VM(s) as specified in the request.
2002 ONAP APPC REST API to Ansible Server is documented separately and can be
2003 found under ONAP (onap.org).
2005 \ **Ansible Server – On-boarding Ansible Playbooks **
2007 Once playbooks are developed following the guidelines listed in prior
2008 section(s), playbooks need to be on-boarded onto Ansible Server(s). In
2009 the future, they’ll be on-boarded and distributed through ONAP, at least
2010 that is the proposed plan, but for now they need to be uploaded
2013 These are the basic steps to on-board playbooks manually onto the
2016 1. Upload CSAR, zip, or tar file containing VNF playbooks and related
2019 2. Create full directory (using –p option below) to store Ansible
2020 Playbooks and other artifacts under /storage file system.
2022 a. Includes VNF type using VNF function code 4 characters under
2025 b. Includes VNF “Version” directory as part of the path to store
2026 playbooks for this VNF version.
2028 c. Include generic ansible root directory. Creating full directory
2031 .. code-block:: none
2033 $ mkdir –p /storage/vfdb/V16.1/ansible**/**
2035 3. Make this directory (VNF ansible root directory) current directory
2038 .. code-block:: none
2040 cd /storage/vfdb/V16.1/ansible/
2042 4. Extract Ansible Playbooks and other Ansible artifacts associated with
2043 the playbooks onto the ansible directory. Command depends on the type
2044 of file uploaded, examples would be:
2046 .. code-block:: none
2052 5. Create directory for VNF (VMs) inventory hosts file with all VMs and
2053 OA&M IP addresses for all VNF instances with known OA&M IP addresses
2054 for respective VMs, example:
2056 .. code-block:: none
2058 $ mkdir –p inventory/vfdb9904v
2060 $ touch inventory/vfdb9904v/hosts
2062 $ cat inventory/vfdb9904v/hosts
2065 localhost ansible\_connection=local
2068 1xx.2yy.zzz.109 ansible\_ssh\_private\_key\_file=/storage/.ssh/Kilo-SSH-Key.pem
2069 1xx.2yy.zzz.110 ansible\_ssh\_private\_key\_file=/storage/.ssh/Kilo-SSH-Key.pem
2072 1xx.2yy.zzz.105 ansible\_ssh\_private\_key\_file=/storage/.ssh/Kilo-SSH-Key.pem
2073 1xx.2yy.zzz.106 ansible\_ssh\_private\_key\_file=/storage/.ssh/Kilo-SSH-Key.pem
2075 6. Create directory to hold default arguments for each VNF instance,
2078 .. code-block:: none
2080 $ mkdir –p vars/vfdb9904v
2081 $ touch vars/vfdb9904v/default\_args.yml
2082 $ cat vars/vfdb9904v/default\_args.yml

2110 7. Perform some basic playbook validation running with “--check” option,
2111 running dummy playbooks or other.
2113 8. Upload any SSH keys referenced on hosts file to appropriate
2116 NOTE: HOT templates used by Heat to instantiate VNF configured by these
2117 playbooks shall include the same SSH key to be installed as part of
2120 Other non-VNF provider specific playbook tasks need to be incorporated on
