module: vertica_role
short_description: Adds or removes Vertica database roles and assigns roles to them.
description:
- Adds or removes Vertica database role and, optionally, assign other roles.
options:
role:
description:
- Name of the role to add or remove.
required: true
type: str
aliases: ['name']
assigned_roles:
description:
- Comma separated list of roles to assign to the role.
aliases: ['assigned_role']
type: str
state:
description:
- Whether to create C(present), drop C(absent) or lock C(locked) a role.
choices: ['present', 'absent']
default: present
type: str
db:
description:
- Name of the Vertica database.
type: str
cluster:
description:
- Name of the Vertica cluster.
default: localhost
type: str
port:
description:
- Vertica cluster port to connect to.
default: 5433
type: str
login_user:
description:
- The username used to authenticate with.
default: dbadmin
type: str
login_password:
description:
- The password used to authenticate with.
type: str
notes:
- The default authentication assumes that you are either logging in as or sudo'ing
to the C(dbadmin) account on the host.
- This module uses C(pyodbc), a Python ODBC database adapter. You must ensure
that C(unixODBC) and C(pyodbc) is installed on the host and properly configured.
- Configuring C(unixODBC) for Vertica requires C(Driver = /opt/vertica/lib64/libverticaodbc.so)
to be added to the C(Vertica) section of either C(/etc/odbcinst.ini) or C($HOME/.odbcinst.ini)
and both C(ErrorMessagesPath = /opt/vertica/lib64) and C(DriverManagerEncoding = UTF-16)
to be added to the C(Driver) section of either C(/etc/vertica.ini) or C($HOME/.vertica.ini).
requirements: [ 'unixODBC', 'pyodbc' ]
