### Graceful Shutdown
1. Pod marked for deletion → removed from Service endpoints
2. `preStop` hook runs (e.g., `sleep 5` to drain connections)
3. `SIGTERM` sent to PID 1
4. `terminationGracePeriodSeconds` countdown (default 30s)
5. `SIGKILL` if still running
### Init Containers
Run sequentially before app containers start. Use for: waiting on dependencies, database migrations, config generation, permission setup.
### Sidecar Containers (v1.29+)
```
### Cilium (21 CRDs)
`IO::K8s::Cilium` covers `cilium.io/v2` and `cilium.io/v2alpha1` (upstream v1.19.2):
```perl
my $k8s = IO::K8s->new(with => ['IO::K8s::Cilium']);
my $cnp = $k8s->new_object('CiliumNetworkPolicy',
metadata => { name => 'allow-dns', namespace => 'kube-system' },
spec => { endpointSelector => {} },
);
```
### Traefik (10 CRDs)
`IO::K8s::Traefik` covers `traefik.io/v1alpha1`:
```perl
my $k8s = IO::K8s->new(with => ['IO::K8s::Traefik']);
my $ir = $k8s->new_object('IngressRoute',
```
### pk8s DSL
In `.pk8s` manifest files, Cilium kinds work directly:
```perl
CiliumNetworkPolicy {
name => 'allow-dns',
namespace => 'kube-system',
spec => { endpointSelector => {} },
};
CiliumNode {
name => 'worker-1',
spec => { addresses => [{ type => 'InternalIP', ip => '10.0.0.1' }] },
};
```
## Custom Resource Definitions (CRDs)
lib/IO/K8s.pm view on Meta::CPAN
=head1 CILIUM CRD SUPPORT
IO::K8s includes L<IO::K8s::Cilium> with 23 Cilium CRD classes covering
C<cilium.io/v2> (12 CRDs) and C<cilium.io/v2alpha1> (11 CRDs). These are
not loaded by default -- opt in at construction:
my $k8s = IO::K8s->new(with => ['IO::K8s::Cilium']);
my $cnp = $k8s->new_object('CiliumNetworkPolicy',
metadata => { name => 'allow-dns', namespace => 'kube-system' },
spec => { endpointSelector => { matchLabels => { app => 'dns' } } },
);
print $cnp->to_yaml;
All Cilium kinds are C<Cilium>-prefixed, so there are no collisions with
core Kubernetes kind names.

lib/IO/K8s/Api/Certificates/V1/CertificateSigningRequest.pm view on Meta::CPAN
=head1 VERSION
version 1.100
=head1 DESCRIPTION
CertificateSigningRequest objects provide a mechanism to obtain x509 certificates by submitting a certificate signing request, and having it asynchronously approved and issued.
Kubelets use this API to obtain:
1. client certificates to authenticate to kube-apiserver (with the "kubernetes.io/kube-apiserver-client-kubelet" signerName).
2. serving certificates for TLS endpoints kube-apiserver can connect to securely (with the "kubernetes.io/kubelet-serving" signerName).
This API can be used to request client certificates to authenticate to kube-apiserver (with the "kubernetes.io/kube-apiserver-client" signerName), or to obtain certificates from custom non-Kubernetes signers.
This is a Kubernetes API object. See L<IO::K8s::Role::APIObject> for
C<metadata>, C<api_version()>, and C<kind()>.
=head2 spec
spec contains the certificate request, and is immutable after creation. Only the request, signerName, expirationSeconds, and usages fields can be set on creation. Other fields are derived by Kubernetes and cannot be modified by users.
lib/IO/K8s/Api/Certificates/V1/CertificateSigningRequestSpec.pm view on Meta::CPAN
signerName indicates the requested signer, and is a qualified name.
List/watch requests for CertificateSigningRequests can filter on this field using a "spec.signerName=NAME" fieldSelector.
Well-known Kubernetes signers are:
1. "kubernetes.io/kube-apiserver-client": issues client certificates that can be used to authenticate to kube-apiserver.
Requests for this signer are never auto-approved by kube-controller-manager, can be issued by the "csrsigning" controller in kube-controller-manager.
2. "kubernetes.io/kube-apiserver-client-kubelet": issues client certificates that kubelets use to authenticate to kube-apiserver.
Requests for this signer can be auto-approved by the "csrapproving" controller in kube-controller-manager, and can be issued by the "csrsigning" controller in kube-controller-manager.
3. "kubernetes.io/kubelet-serving" issues serving certificates that kubelets use to serve TLS endpoints, which kube-apiserver can connect to securely.
Requests for this signer are never auto-approved by kube-controller-manager, and can be issued by the "csrsigning" controller in kube-controller-manager.
More details are available at https://k8s.io/docs/reference/access-authn-authz/certificate-signing-requests/#kubernetes-signers
Custom signerNames can also be specified. The signer defines:
1. Trust distribution: how trust (CA bundles) are distributed.
2. Permitted subjects: and behavior when a disallowed subject is requested.
3. Required, permitted, or forbidden x509 extensions in the request (including whether subjectAltNames are allowed, which types, restrictions on allowed values) and behavior when a disallowed extension is requested.
4. Required, permitted, or forbidden key usages / extended key usages.
5. Expiration/certificate lifetime: whether it is fixed by the signer, configurable by the admin.

IO::K8s::Api::Discovery::V1::EndpointConditions - EndpointConditions represents the current condition of an endpoint.
=head1 VERSION
version 1.100
=head2 ready
ready indicates that this endpoint is prepared to receive traffic, according to whatever system is managing the endpoint. A nil value indicates an unknown state. In most cases consumers should interpret this unknown state as ready. For compatibility ...
=head2 serving
serving is identical to ready except that it is set regardless of the terminating state of endpoints. This condition should be set to true for a ready endpoint that is terminating. If nil, consumers should defer to the ready condition.
=head2 terminating
terminating indicates that this endpoint is terminating. A nil value indicates an unknown state. Consumers should interpret this unknown state to mean that the endpoint is not terminating.

EndpointSlice represents a subset of the endpoints that implement a service. For a given service there may be multiple EndpointSlice objects, selected by labels, which must be joined to produce the full set of endpoints.

=head2 backend
backend defines the referenced service endpoint to which the traffic will be forwarded to.

path is matched against the path of an incoming request. Currently it can contain characters disallowed from the conventional "path" part of a URL as defined by RFC 3986. Paths must begin with a '/' and must be present when using PathType with value ...

pathType determines the interpretation of the path matching. PathType can be one of the following values: * Exact: Matches the URL path exactly. * Prefix: Matches based on a URL path prefix split by '/'. Matching is done on a path element by element ...
