Use Network-Manager and Netplan as default renderers for RHEL and Fedora (#1465)
|
|
|
1160f5 |
|
|
|
1160f5 |
This is adapted from Neal Gompa's PR:
|
|
|
1160f5 |
https://github.com/canonical/cloud-init/pull/1435
|
|
|
1160f5 |
|
|
|
1160f5 |
The only difference is that we are not modifying renderers.py (thus
|
|
|
1160f5 |
modifying the priority of all distros), but just tweaking cloud.cfg to
|
|
|
1160f5 |
apply this change to Fedora and RHEL. Other distros can optionally
|
|
|
1160f5 |
add themselves afterwards.
|

net: Prefer Netplan and NetworkManager renderers by default
|
|
|
1160f5 |
|
|
|
1160f5 |
NetworkManager is used by default on a variety of Linux distributions,
|
|
|
1160f5 |
and exists as a cross-distribution network management service.
|
|
|
1160f5 |
|
|
|
1160f5 |
Additionally, add information about the NetworkManager renderer to
|
|
|
1160f5 |
the cloud-init documentation.
|
|
|
1160f5 |
|
|
|
1160f5 |
Because Netplan can be explicitly used to manage NetworkManager,
|
|
|
1160f5 |
it needs to be preferred before NetworkManager.
|
|
|
1160f5 |
|
|
|
1160f5 |
This change is a follow-up to #1224, which added the native
|
|
|
1160f5 |
NetworkManager renderer.
|
|
|
1160f5 |
This patch has been deployed on Fedora's cloud-init package throughout
|
|
|
1160f5 |
the development of Fedora Linux 36 to verify that it works.
|
|
|
1160f5 |
|
|
|
1160f5 |
This should also make it tremendously easier for Linux distributions
|
|
|
1160f5 |
to use cloud-init because now a standard configuration is supported
|
|
|
1160f5 |
by default.
