debops.neurodebian default variables¶
Sections
General configuration¶
-
neurodebian__deploy_state
¶
What is the desired state which this role should achieve? Possible options:
present
- Default. Ensure that repositories and packages provided by NeuroDebian are installed and configured as requested.
absent
- Ensure that repositories and packages provided by NeuroDebian are absent.
neurodebian__deploy_state: 'present'
-
neurodebian__upstream
¶
When the upstream support is enabled, Ansible will configure NeuroDebian APT
repositories directly. When it's disabled, the role will install the
neurodebian
APT package included in Debian and let it configure the
repositories. The package is included since Debian Stretch.
neurodebian__upstream: '{{ True

[ "wheezy", "jessie", "trusty" ])

neurodebian__apt_mirror

neurodebian__apt_mirror: '{{ neurodebian__region_mirror_map[neurodebian__region]
| d("us-nh") }}'
-
neurodebian__apt_mirror_uri
¶

neurodebian__apt_mirror_uri: '{{ neurodebian__apt_mirror_map[neurodebian__apt_mirror] }}'
Configuration for other Ansible roles¶
-
neurodebian__apt_preferences__dependent_list
¶
APT pinning for packages from the NeuroDebian repository. By default (without this pinning), both the official Debian repositories and NeuroDebian have the same preference which would lead to APT picking the package with the highest version regardless from which repository it comes from.
As NeuroDebian provides many additional packages along with more recent versions of packages already available in official Debian releases, APT pinning is used to ensure that package versions available in official Debian releases are preferred even if NeuroDebian provides newer versions.
The job of setting up the APT pinning is offloaded to the debops.apt_preferences role which is instructed using this variable.
neurodebian__apt_preferences__dependent_list:
- package: '*'
reason: |-
Pin NeuroDebian with priority 80 which is lower then the official Debian backports (100).
This also works when `apt_preferences__preset_list` is set which increases
Debian backports to 400 and decreases Debian testing to 50.
by_role: 'debops.neurodebian'
pin: 'release o=NeuroDebian'
priority: '80'
state: '{{ "present" if (neurodebian__deploy_state == "present") else "absent" }}'
-
neurodebian__keyring__dependent_apt_keys
¶
Configuration for the debops.keyring Ansible role.
neurodebian__keyring__dependent_apt_keys:
# This is needed to avoid apt_key removing the GPG key from the
# 'neurodebian-archive-keyring' APT package
- id: '{{ neurodebian__apt_key_fingerprint if neurodebian__upstream|bool else "" }}'
state: '{{ "present"
if (neurodebian__deploy_state == "present" and
neurodebian__upstream|bool)
else "absent" }}'
