short_description: Ensure packages exist in a RHEL for Edge rpm-ostree based system
|

description:
|
|
- Compatibility layer for using the "package" module for RHEL for Edge systems utilizing the RHEL System Roles.

requirements:

|
|
- A package name or package specifier with version, like C(name-1.0).
|
|
- Comparison operators for package version are valid here C(>), C(<), C(>=), C(<=). Example - C(name>=1.0)
|
|
- If a previous version is specified, the task also needs to turn C(allow_downgrade) on.
|
|
See the C(allow_downgrade) documentation for caveats with downgrading packages.
|
|
- When using state=latest, this can be C('*') which means run C(yum -y update).
|
|
- You can also pass a url or a local path to a rpm file (using state=present).
|
|
To operate on several packages this can accept a comma separated string of packages or (as of 2.0) a list of packages.

description:
|
|
- Whether to install (C(present) or C(installed), C(latest)), or remove (C(absent) or C(removed)) a package.
|
|
- C(present) and C(installed) will simply ensure that a desired package is installed.
|
|
- C(latest) will update the specified package if it's not of the latest available version.
|
|
- C(absent) and C(removed) will remove the specified package.
|
|
- Default is C(None), however in effect the default action is C(present) unless the C(autoremove) option is
|
|
enabled for this module, then C(absent) is inferred.
|
|
type: str
|
|
choices: [ absent, installed, latest, present, removed ]
|
|
notes:
|
|
- This module does not support installing or removing packages to/from an overlay as this is not supported
|
|
by RHEL for Edge, packages needed should be defined in the osbuild Blueprint and provided to Image Builder
|
|
at build time. This module exists only for C(package) module compatibility.
