ovirt_auth – Module to manage authentication to oVirt/RHV

New in version 2.2.

Synopsis

  • This module authenticates to oVirt/RHV engine and creates SSO token, which should be later used in all other oVirt/RHV modules, so all modules don’t need to perform login and logout. This module returns an Ansible fact called ovirt_auth. Every module can use this fact as auth parameter, to perform authentication.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.7
  • ovirt-engine-sdk-python >= 4.2.4

Parameters

Parameter Choices/Defaults Comments
ca_file
-
A PEM file containing the trusted CA certificates. The certificate presented by the server will be verified using these CA certificates. If ca_file parameter is not set, system wide CA certificate store is used. Default value is set by OVIRT_CAFILE environment variable.
compress
-
A boolean flag indicating if the SDK should ask the server to send compressed responses. The default is True. Note that this is a hint for the server, and that it may return uncompressed data even when this parameter is set to True.
headers
-
added in 2.4
A dictionary of HTTP headers to be added to each API call.
hostname
-
added in 2.6
A string containing the hostname of the server. For example: server.example.com. Default value is set by OVIRT_HOSTNAME environment variable.
Either url or hostname is required.
insecure
-
A boolean flag that indicates if the server TLS certificate and host name should be checked.
kerberos
-
A boolean flag indicating if Kerberos authentication should be used instead of the default basic authentication.
password
-
The password of the user. Default value is set by OVIRT_PASSWORD environment variable.
state
-
    Choices:
  • present ←
  • absent
Specifies if a token should be created or revoked.
timeout
-
The maximum total time to wait for the response, in seconds. A value of zero (the default) means wait forever. If the timeout expires before the response is received an exception will be raised.
token
-
added in 2.5
SSO token to be used instead of login with username/password. Default value is set by OVIRT_TOKEN environment variable.
url
-
A string containing the API URL of the server. For example: https://server.example.com/ovirt-engine/api. Default value is set by OVIRT_URL environment variable.
Either url or hostname is required.
username
-
The name of the user. For example: admin@internal Default value is set by OVIRT_USERNAME environment variable.

Notes

Note

  • Everytime you use ovirt_auth module to obtain ticket, you need to also revoke the ticket, when you no longer need it, otherwise the ticket would be revoked by engine when it expires. For an example of how to achieve that, please take a look at examples section.
  • In order to use this module you have to install oVirt/RHV Python SDK. To ensure it’s installed with correct version you can create the following task: pip: name=ovirt-engine-sdk-python version=4.2.4
  • Note that in oVirt/RHV 4.1 if you want to use a user which is not administrator you must enable the ENGINE_API_FILTER_BY_DEFAULT variable in engine. In oVirt/RHV 4.2 and later it’s enabled by default.

Examples

  - block:
       # Create a vault with `ovirt_password` variable which store your
       # oVirt/RHV user's password, and include that yaml file with variable:
       - include_vars: ovirt_password.yml

       - name: Obtain SSO token with using username/password credentials
         ovirt_auth:
           url: https://ovirt.example.com/ovirt-engine/api
           username: admin@internal
           ca_file: ca.pem
           password: "{{ ovirt_password }}"

       # Previous task generated I(ovirt_auth) fact, which you can later use
       # in different modules as follows:
       - ovirt_vms:
           auth: "{{ ovirt_auth }}"
           state: absent
           name: myvm

    always:
      - name: Always revoke the SSO token
        ovirt_auth:
          state: absent
          ovirt_auth: "{{ ovirt_auth }}"

# When user will set following environment variables:
#   OVIRT_URL = https://fqdn/ovirt-engine/api
#   OVIRT_USERNAME = admin@internal
#   OVIRT_PASSWORD = the_password
# User can login the oVirt using environment variable instead of variables
# in yaml file.
# This is mainly useful when using Ansible Tower or AWX, as it will work
# for Red Hat Virtualization creadentials type.
  - name: Obtain SSO token
    ovirt_auth:
      state: present
