while fixing #87, noticed a couple lines down that if the containers
spec has more than 1 container, the code probably intends to set
Spec.Containers to a list with a single container, but is instead
setting it to an empty list. The very next lines are trying to access
the 1st element of this empty list, which will result in a panic
Pod labels are being set in line 242, and the`podLabels` variable
already contains the extra `"app.kubernetes.io/name": "netbird-router"`
label, so lines 244-246 are effectively just overwriting any labels that
have been set in the crd.
This is blocking us from using this crd because we need a label
disabling istio injection for the peer to work correctly.

Changes:
* Split kubernetes-operator Chart to operator only chart
(kubernetes-operator) and configuration chart (netbird-operator-config)
* Remove delete validation webhooks for non-needed resources
* Allow abandoning Groups when still linked to a resource for over a
minute after deletion
* Fix duplciate Network Resource retrying heavily
* Fix SetupKey creation duplication
* Skip deleting routing peer since deleting network automatically
deletes it anyway
# Fix: NetBird extra-dns-labels not being applied to pods
## Problem
The `netbird.io/extra-dns-labels` annotation was not working when
applied to pods. Despite the webhook detecting the annotation and adding
it to the NetBird container configuration, the extra DNS labels were not
appearing in the NetBird UI or being applied to registered peers.
## Root Cause
The pod webhook had two issues:
1. **Invalid setup key argument**: The webhook was passing
`--setup-key-file /etc/nbkey` to the NetBird client, but this file path
was never created. The setup key was already being passed via the
`NB_SETUP_KEY` environment variable, making the file-based approach
unnecessary and causing confusion in the client startup.
2. **NetBird CLI flag bug**: The webhook was using the
`--extra-dns-labels` command line flag, but NetBird has a known issue
([netbirdio/netbird#4282](https://github.com/netbirdio/netbird/issues/4282))
where this flag is not properly processed. The workaround is to use the
`NB_EXTRA_DNS_LABELS` environment variable instead.
## Solution
- Removed the `--setup-key-file` argument entirely since the setup key
is provided via environment variable
- Removed all command line arguments from the NetBird container
- Added `NB_EXTRA_DNS_LABELS` environment variable when the
`netbird.io/extra-dns-labels` annotation is present
- NetBird client now uses only environment variables for configuration,
which is more reliable and matches the pattern used by the NBRoutingPeer
controller
## Changes
**Before:**
```go
args := []string{
"--setup-key-file", "/etc/nbkey",
"-m", managementURL,
}
// ... add extra-dns-labels to args
```
**After:**
```go
envVars := []corev1.EnvVar{
{Name: "NB_SETUP_KEY", ValueFrom: ...},
{Name: "NB_MANAGEMENT_URL", Value: managementURL},
}
// ... conditionally add NB_EXTRA_DNS_LABELS to envVars
```
## Testing
1. Create a deployment with the `netbird.io/setup-key` and
`netbird.io/extra-dns-labels` annotations:
```yaml
annotations:
netbird.io/setup-key: my-setup-key
netbird.io/extra-dns-labels: "my-label,another-label"
```
2. Verify the environment variable is set:
```bash
kubectl get pod <pod-name> -o jsonpath='{.spec.containers[?(@.name=="netbird")].env[*]}' | jq .
```
3. Check the NetBird UI to confirm the extra DNS labels appear on the
registered peer
4. Verify the NetBird container logs show successful registration
without errors

This fix ensures that the `netbird.io/extra-dns-labels` annotation works
as documented and provides a more robust configuration method by using
environment variables consistently across all NetBird deployments in the
operator.
The reason for this PR is that currently if the secret doesn’t have the
key NB_API_KEY yet at deployment time, the deployment will still run and
pull in an env list that doesn’t include NB_API_KEY since the envFrom
will just pull any and all keys it finds in the secret and makes env
vars out of them. then at a later point, once the NB_API_KEY key is
populated in the secret, one has to bounce the pod to get the key to be
picked up.
if you use the env: valueFrom syntax using a named key, if that named
key doesn’t exist, the deployment should give an error and retry until
the secret key is available
Operator checks for existence of NetBird API key to create controllers
for Service, NBResource, NBPolicy ...etc, while the Helm chart checks
for Values.ingress.enabled, this causes crashes if NetBird API Key is
provided but ingress.enabled is set to `false`.
This fixes this discrepancy by checking NetBird API key in Helm instead
of ingress enabled value.

Goreleaser was causing issues when helm chart action created releases
for packaged helm chart, this PR replaces goreleaser with a much simpler
build and push model, and returns packaged helm charts to normal.
- It adds a helm chart that will be hosted in the Github pages URL of this repository
- an admission controller operator
- Basic documentation for installing the operator, configuring CRDs and example pod configuration
