The settings of the ConfigMap-and-YAML deployment have to become objects before
the mechanisms that held them can go. The command reads what the old console
wrote (the zone--<apex>.zone keys of the zones ConfigMap and the
address-overrides RPZ), and optionally the resolver's config.yaml, and converts:
zone master files -> DNSZone
address-overrides RPZ -> AddressOverride, one per name
URL blocklists -> BlockList
allow_entries/block_entries -> DomainRule inline-allow / inline-block
acl.groups -> ClientGroup
By default it only prints manifests, which can be reviewed or committed; -apply
creates or updates the objects. It never deletes or edits the ConfigMaps or the
config. Each conversion is validated with the code the resolver uses to read the
objects, and anything it cannot represent faithfully is listed and left alone:
a zone with a record type the API does not write, a list that is a file on the
pod, a name that is not a legal object name, an RPZ line that is not an A or
AAAA override. Tests apply a conversion of the live data to a fake cluster and
read it back through the resolver's source, and run the command against fake
ConfigMaps, offline from files, and with the ConfigMaps missing.

The address redirects page rewrote an RPZ ConfigMap through the resolver's own
service account, and the domains page rewrote allow_entries/block_entries in the
config file. Both become cluster objects like the rest.
AddressOverride is one name answered with fixed addresses (the name and
everything under it), exactly what an RPZ "name A address" line did. DomainRule
is a block or allow list of inline names. The resolver reads both with the
existing watch: overrides are rendered into the managed RPZ source the blocklist
manager already has, and rule names join the config's inline entries in the
merged overlay, so the file's config is never written to.
Names are checked to be DNS names or wildcard patterns before they are used,
because they are joined into line-oriented parser input and a newline or a
comment character in one would otherwise add a rule of its own.
The console edits both: the address-overrides and domains endpoints now write
objects. The console keeps its added rules in one DomainRule per action
(inline-block, inline-allow) instead of an object per name, and removes a name
from whichever DomainRule holds it, wildcard or not. An end-to-end test drives
the pages' endpoints and checks the resolver's answers.

fancy-dns-console is a second binary holding the web UI, authentication and
every edit. It writes ClientGroup, BlockList and DNSZone objects through the new
kubeedit package and forwards all other /api routes to a running resolver
with its own key, dropping the browser's credentials, so it can run in the
cluster or on a workstation with a kubeconfig and nothing about the resolver's
placement matters. The resolver never imports kubeedit and the console is not on
the DNS path.
kubeedit validates every spec with the runtime's own converters
(kubesource.CheckGroup/CheckList/CheckZone) before writing, so the console
cannot store an object the resolver would reject. Zone edits keep the
file-based writer's behaviour: duplicate and below-a-delegation records are
refused, a delegation in a new zone also gives the zone its servers, and a
zone with no apex NS is never stored. Each object records the editing user in
an annotation; updates retry on conflict.
The resolver reports groups from ClientGroup objects as source "kubernetes" and
counter-only rows (the "(default)" bucket, or a group removed since) as
"history", and lists DNSZone zones as the editable ones. The console uses that
to leave the YAML's groups alone and to drop history rows, which the UI would
otherwise send back on save. Its GET /api/clients overlays the cluster's
current objects on the resolver's list, because the resolver only sees an edit
after its watch fires and a save made just after another would delete the
first.
An end-to-end test runs both halves against one fake apiserver: a group saved
through the console refuses queries, a zone built record by record answers
authoritatively, and a request with the resolver's own key is rejected by the
console.
