short_description: Add and remove YUM repositories

description:
|
|
- Add or remove YUM repositories in RPM-based Linux distributions.

options:
|

async:
|
|
required: false

|
choices: ['yes', 'no']
|
|
default: 'yes'

|
- If set to C(yes) Yum will download packages and metadata from this
|
|
repo in parallel, if possible.
|
|
bandwidth:
|
|
required: false
|
|
default: 0
|
|
description:
|
|
- Maximum available network bandwidth in bytes/second. Used with the
|
|
I(throttle) option.
|
|
- If I(throttle) is a percentage and bandwidth is C(0) then bandwidth
|
|
throttling will be disabled. If I(throttle) is expressed as a data rate
|
|
(bytes/sec) then this option is ignored. Default is C(0) (no bandwidth
|
|
throttling).
|
|
baseurl:
|
|
required: false
|
|
default: null
|
|
description:
|
|
- URL to the directory where the yum repository's 'repodata' directory

deltarpm_metadata_percentage:

required: false
|
|
default: 100
|
|
description:
|
|
- When the relative size of deltarpm metadata vs pkgs is larger than
|
|
this, deltarpm metadata is not downloaded from the repo. Note that you
|
|
can give values over C(100), so C(200) means that the metadata is
|
|
required to be half the size of the packages. Use C(0) to turn off
|
|
this check, and always download metadata.
|
|
deltarpm_percentage:
|
|
required: false
|
|
default: 75
|
|
description:
|
|
- When the relative size of delta vs pkg is larger than this, delta is
|
|
not used. Use C(0) to turn off delta rpm processing. Local repositories
|
|
(with file:// I(baseurl)) have delta rpms turned off by default.

default: 'read-only:present'
|
|
description:
|
|
- Filter the I(metadata_expire) time, allowing a trade of speed for
|
|
accuracy if a command doesn't require it. Each yum command can specify
|
|
that it requires a certain level of timeliness quality from the remote
|
|
repos. from "I'm about to install/upgrade, so this better be current"
|
|
to "Anything that's available is good enough".
|
|
- C(never) - Nothing is filtered, always obey I(metadata_expire).
|
|
- C(read-only:past) - Commands that only care about past information are
|
|
filtered from metadata expiring. Eg. I(yum history) info (if history

needs to lookup anything about a previous transaction, then by

definition the remote package was available in the past).

|
|
future. Eg. I(yum list yum).
