module: ansible_galaxy_install
author:
- "Alexei Znamensky (@russoz)"
short_description: Install Ansible roles or collections using ansible-galaxy
version_added: 3.5.0
description:
- This module allows the installation of Ansible collections or roles using C(ansible-galaxy).
notes:
- >
B(Ansible 2.9/2.10): The C(ansible-galaxy) command changed significantly between Ansible 2.9 and
ansible-base 2.10 (later ansible-core 2.11). See comments in the parameters.
requirements:
- Ansible 2.9, ansible-base 2.10, or ansible-core 2.11 or newer
options:
type:
description:
- The type of installation performed by C(ansible-galaxy).
- If I(type) is C(both), then I(requirements_file) must be passed and it may contain both roles and collections.
- "Note however that the opposite is not true: if using a I(requirements_file), then I(type) can be any of the three choices."
- "B(Ansible 2.9): The option C(both) will have the same effect as C(role)."
type: str
choices: [collection, role, both]
required: true
name:
description:
- Name of the collection or role being installed.
- >
Versions can be specified with C(ansible-galaxy) usual formats.
For example, the collection C(community.docker:1.6.1) or the role C(ansistrano.deploy,3.8.0).
- I(name) and I(requirements_file) are mutually exclusive.
type: str
requirements_file:
description:
- Path to a file containing a list of requirements to be installed.
- It works for I(type) equals to C(collection) and C(role).
- I(name) and I(requirements_file) are mutually exclusive.
- "B(Ansible 2.9): It can only be used to install either I(type=role) or I(type=collection), but not both at the same run."
type: path
dest:
description:
- The path to the directory containing your collections or roles, according to the value of I(type).
- >
Please notice that C(ansible-galaxy) will not install collections with I(type=both), when I(requirements_file)
contains both roles and collections and I(dest) is specified.
type: path
no_deps:
description:
- Refrain from installing dependencies.
version_added: 4.5.0
type: bool
default: false
force:
description:
- Force overwriting an existing role or collection.
- Using I(force=true) is mandatory when downgrading.
- "B(Ansible 2.9 and 2.10): Must be C(true) to upgrade roles and collections."
type: bool
default: false
ack_ansible29:
description:
- Acknowledge using Ansible 2.9 with its limitations, and prevents the module from generating warnings about them.
- This option is completely ignored if using a version of Ansible greater than C(2.9.x).
- Note that this option will be removed without any further deprecation warning once support
for Ansible 2.9 is removed from this module.
type: bool
default: false
ack_min_ansiblecore211:
description:
- Acknowledge the module is deprecating support for Ansible 2.9 and ansible-base 2.10.
- Support for those versions will be removed in community.general 8.0.0.
At the same time, this option will be removed without any deprecation warning!
- This option is completely ignored if using a version of ansible-core/ansible-base/Ansible greater than C(2.11).
- For the sake of conciseness, setting this parameter to C(true) implies I(ack_ansible29=true).
type: bool
default: false
