Cilium's init containers run as UID 0 with capabilities (including
CAP_DAC_OVERRIDE) dropped, so host paths it writes to (e.g. /opt/cni/bin)
must be owned by root or it will fail with a permission error.
Add a pre-flight assert that fails fast with a clear message when
kube_network_plugin == cilium and kube_owner != root, instead of
changing CNI bin ownership defaults for all network plugins.
Remove the Flatcar/Fedora CoreOS exclusion from the wait handler
and unify the Flatcar-specific notify channel into the shared
"propagate resolvconf to k8s components" channel.
* Remove tag master
Following it's deprecation in 4b324cb0f (Rename master to control plane
- non-breaking changes only (#11394), 2024-09-06)
* Add fail fast path when using removed tags
- Used for the master tag, but this could be used for other things in
the future
The preinstall assert cover a number of things, many of which depends
only on the inventory, and can be run without any ansible_facts
collected.
Split them off to simplify re-ordering.
The versions which are by default derived from `kube_version` can break
the assert if kube_version start with `v`, because they use the start of
`kube_version` as dict key.
By putting them in their own assert, the first assert should trigger on
`kube_version`, with a more explicit error.
This has been deprecated for a long time, time to pull the plug.
We leave an assert for one release to have a straightforward failure if
some users were still using the variable.
Since 'none' can be, for instance, a manual calico deployment, don't
check whether there is enough ip for pods on a node, because the plugin
can use another mechanism than the podCIDR to allocate IPs.
When the etcd group is not specified we assume it's kube_control_plane.
In that case, etcd still can't be even, so instead of only checking the
etcd group we need to default to kube_control_plane
This avoids spurious failure with 'localhost'.
It should also be more correct the inventory contains uncached hosts
which are not in `k8s_cluster` and therefore should not be Kubespray
business.
(We still use hostvars for uncached hosts, because it's easier to select
on 'ansible_default_ipv4' that way and does not change the end result)
We use a lot of facts where variables are enough, and format too early,
which prevent reusing the variables in different contexts.
- Moves set_fact variables to the vars directory, remove unnecessary
intermediate variables, and render them at usage sites to only do logic
on native Ansible/Jinja lists.
- Use defaults/ rather than default filters for several variables.
- Lookup was not returning a list, making the difference filter spit out
garbage -> query always return a list
- hostvars is a dictionnary, so convert to list before selectattr and
map back to only get keys
