idRequired
  • Type: java.lang.String
metadataOptional

Metadata that all persisted resources must have, which includes all objects users must create.

automountServiceAccountTokenOptional
  • Type: java.lang.Boolean
  • Default: false

Indicates whether a service account token should be automatically mounted.

https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#use-the-default-service-account-to-access-the-api-server

containersOptional

List of containers belonging to the pod.

Containers cannot currently be added or removed. There must be at least one container in a Pod.

You can add additionnal containers using podSpec.addContainer()

dnsOptional

DNS settings for the pod.

https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/

dockerRegistryAuthOptional

A secret containing docker credentials for authenticating to a registry.

HostAlias holds the mapping between IP and hostnames that will be injected as an entry in the pod’s hosts file.

hostNetworkOptional
  • Type: java.lang.Boolean
  • Default: false

Host network for the pod.

initContainersOptional

List of initialization containers belonging to the pod.

Init containers are executed in order prior to containers being started. If any init container fails, the pod is considered to have failed and is handled according to its restartPolicy. The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion.

Init containers cannot currently be added ,removed or updated.

https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

isolateOptional

A service account provides an identity for processes that run in a Pod.

When you (a human) access the cluster (for example, using kubectl), you are authenticated by the apiserver as a particular User Account (currently this is usually admin, unless your cluster administrator has customized your cluster). Processes in containers inside pods can also contact the apiserver. When they do, they are authenticated as a particular Service Account (for example, default).

https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/

terminationGracePeriodOptional

podMetadataOptional

The pod metadata of this workload.

selectOptional
  • Type: java.lang.Boolean
  • Default: true

Automatically allocates a pod label selector for this workload and add it to the pod metadata.

This ensures this workload manages pods created by its pod template.

spreadOptional
  • Type: java.lang.Boolean
  • Default: false

Automatically spread pods across hostname and zones.

https://kubernetes.io/docs/concepts/scheduling-eviction/topology-spread-constraints/#internal-default-constraints

activeDeadlineOptional

Specifies the duration the job may be active before the system tries to terminate it.

backoffLimitOptional
  • Type: java.lang.Number
  • Default: If not set, system defaults to 6.

Specifies the number of retries before marking this job failed.

ttlAfterFinishedOptional
  • Type: org.cdk8s.Duration
  • Default: If this field is unset, the Job won’t be automatically deleted.

Limits the lifetime of a Job that has finished execution (either Complete or Failed).

If this field is set, after the Job finishes, it is eligible to be automatically deleted. When the Job is being deleted, its lifecycle guarantees (e.g. finalizers) will be honored. If this field is set to zero, the Job becomes eligible to be deleted immediately after it finishes. This field is alpha-level and is only honored by servers that enable the TTLAfterFinished feature.

Specifies the time in which the job would run again.

This is defined as a cron expression in the CronJob resource.

concurrencyPolicyOptional

Specifies the concurrency policy for the job.

failedJobsRetainedOptional
  • Type: java.lang.Number
  • Default: 1

Specifies the number of failed jobs history retained.

This would retain the Job and the associated Pod resource and can be useful for debugging.

startingDeadlineOptional

Kubernetes attempts to start cron jobs at its schedule time, but this is not guaranteed.

This deadline specifies how much time can pass after a schedule point, for which kubernetes can still start the job. For example, if this is set to 100 seconds, kubernetes is allowed to start the job at a maximum 100 seconds after the scheduled time.

Note that the Kubernetes CronJobController checks for things every 10 seconds, for this reason, a deadline below 10 seconds is not allowed, as it may cause your job to never be scheduled.

In addition, kubernetes will stop scheduling jobs if more than 100 schedules were missed (for any reason). This property also controls what time interval should kubernetes consider when counting for missed schedules.

For example, suppose a CronJob is set to schedule a new Job every one minute beginning at 08:30:00, and its startingDeadline field is not set. If the CronJob controller happens to be down from 08:29:00 to 10:21:00, the job will not start as the number of missed jobs which missed their schedule is greater than 100. However, if startingDeadline is set to 200 seconds, kubernetes will only count 3 missed schedules, and thus start a new execution at 10:22:00.

successfulJobsRetainedOptional
  • Type: java.lang.Number
  • Default: 3

Specifies the number of successful jobs history retained.

This would retain the Job and the associated Pod resource and can be useful for debugging.

DaemonSet

A DaemonSet ensures that all (or some) Nodes run a copy of a Pod.

As nodes are added to the cluster, Pods are added to them. As nodes are removed from the cluster, those Pods are garbage collected. Deleting a DaemonSet will clean up the Pods it created.

Some typical uses of a DaemonSet are:

  • running a cluster storage daemon on every node
  • running a logs collection daemon on every node
  • running a node monitoring daemon on every node

In a simple case, one DaemonSet, covering all nodes, would be used for each type of daemon. A more complex setup might use multiple DaemonSets for a single type of daemon, but with different flags and/or different memory and cpu requests for different hardware types.

Deployment

A Deployment provides declarative updates for Pods and ReplicaSets.

You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. You can define Deployments to create new ReplicaSets, or to remove existing Deployments and adopt all their resources with new Deployments.

Note: Do not manage ReplicaSets owned by a Deployment. Consider opening an issue in the main Kubernetes repository if your use case is not covered below.

Use Case

The following are typical use cases for Deployments:

  • Create a Deployment to rollout a ReplicaSet. The ReplicaSet creates Pods in the background. Check the status of the rollout to see if it succeeds or not.
  • Declare the new state of the Pods by updating the PodTemplateSpec of the Deployment. A new ReplicaSet is created and the Deployment manages moving the Pods from the old ReplicaSet to the new one at a controlled rate. Each new ReplicaSet updates the revision of the Deployment.
  • Rollback to an earlier Deployment revision if the current state of the Deployment is not stable. Each rollback updates the revision of the Deployment.
  • Scale up the Deployment to facilitate more load.
  • Pause the Deployment to apply multiple fixes to its PodTemplateSpec and then resume it to start a new rollout.
  • Use the status of the Deployment as an indicator that a rollout has stuck.
  • Clean up older ReplicaSets that you don’t need anymore.

HorizontalPodAutoscaler

A HorizontalPodAutoscaler scales a workload up or down in response to a metric change.

This allows your services to scale up when demand is high and scale down when they are no longer needed.

Typical use cases for HorizontalPodAutoscaler:

  • When Memory usage is above 70%, scale up the number of replicas to meet the demand.
  • When CPU usage is below 30%, scale down the number of replicas to save resources.
  • When a service is experiencing a spike in traffic, scale up the number of replicas to meet the demand. Then, when the traffic subsides, scale down the number of replicas to save resources.

The autoscaler uses the following algorithm to determine the number of replicas to scale:

desiredReplicas = ceil[currentReplicas * ( currentMetricValue / desiredMetricValue )]

HorizontalPodAutoscaler’s can be used to with any Scalable workload:

  • Deployment
  • StatefulSet

Targets that already have a replica count defined:

Remove any replica counts from the target resource before associating with a HorizontalPodAutoscaler. If this isn’t done, then any time a change to that object is applied, Kubernetes will scale the current number of Pods to the value of the target.replicas key. This may not be desired and could lead to unexpected behavior.

This field is a reference to an IngressClass resource that contains additional Ingress configuration, including the name of the Ingress controller.

defaultBackendOptional

The default backend services requests that do not match any rule.

Using this option or the addDefaultBackend() method is equivalent to adding a rule with both path and host undefined.

rulesOptional

Routing rules for this ingress.

Each rule must define an IngressBackend that will receive the requests that match this rule. If both host and path are not specifiec, this backend will be used as the default backend of the ingress.

You can also add rules later using addRule(), addHostRule(), addDefaultBackend() and addHostDefaultBackend().

tlsOptional

TLS settings for this ingress.

Using this option tells the ingress controller to expose a TLS endpoint. Currently the Ingress only supports a single TLS port, 443. If multiple members of this list specify different hosts, they will be multiplexed on the same port according to the hostname specified through the SNI TLS extension, if the ingress controller fulfilling the ingress supports SNI.

Job

A Job creates one or more Pods and ensures that a specified number of them successfully terminate.

As pods successfully complete, the Job tracks the successful completions. When a specified number of successful completions is reached, the task (ie, Job) is complete. Deleting a Job will clean up the Pods it created. A simple case is to create one Job object in order to reliably run one Pod to completion. The Job object will start a new Pod if the first Pod fails or is deleted (for example due to a node hardware failure or a node reboot). You can also use a Job to run multiple Pods in parallel.

initContainersOptional

List of initialization containers belonging to the pod.

Init containers are executed in order prior to containers being started. If any init container fails, the pod is considered to have failed and is handled according to its restartPolicy. The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion.

Init containers cannot currently be added ,removed or updated.

https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

Namespace

In Kubernetes, namespaces provides a mechanism for isolating groups of resources within a single cluster.

Names of resources need to be unique within a namespace, but not across namespaces. Namespace-based scoping is applicable only for namespaced objects (e.g. Deployments, Services, etc) and not for cluster-wide objects (e.g. StorageClass, Nodes, PersistentVolumes, etc).

NetworkPolicy

Control traffic flow at the IP address or port level (OSI layer 3 or 4), network policies are an application-centric construct which allow you to specify how a pod is allowed to communicate with various network peers.

  • Outgoing traffic is allowed if there are no network policies selecting the pod (and cluster policy otherwise allows the traffic), OR if the traffic matches at least one egress rule across all of the network policies that select the pod.
  • Incoming traffic is allowed to a pod if there are no network policies selecting the pod (and cluster policy otherwise allows the traffic), OR if the traffic source is the pod’s local node, OR if the traffic matches at least one ingress rule across all of the network policies that select the pod.

Network policies do not conflict; they are additive. If any policy or policies apply to a given pod for a given direction, the connections allowed in that direction from that pod is the union of what the applicable policies allow. Thus, order of evaluation does not affect the policy result.

For a connection from a source pod to a destination pod to be allowed, both the egress policy on the source pod and the ingress policy on the destination pod need to allow the connection. If either side does not allow the connection, it will not happen.

PersistentVolume

A PersistentVolume (PV) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using Storage Classes.

It is a resource in the cluster just like a node is a cluster resource. PVs are volume plugins like Volumes, but have a lifecycle independent of any individual Pod that uses the PV. This API object captures the details of the implementation of the storage, be that NFS, iSCSI, or a cloud-provider-specific storage system.

storageClassNameOptional
  • Type: java.lang.String
  • Default: Not set.

Name of the StorageClass required by the claim. When this property is not set, the behavior is as follows:.

  • If the admission plugin is turned on, the storage class marked as default will be used.
  • If the admission plugin is turned off, the pvc can only be bound to volumes without a storage class.

https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1

volumeOptional

The PersistentVolume backing this claim.

The control plane still checks that storage class, access modes, and requested storage size on the volume are valid.

Note that in order to guarantee a proper binding, the volume should also define a claimRef referring to this claim. Otherwise, the volume may be claimed be other pvc’s before it gets a chance to bind to this one.

If the volume is managed (i.e not imported), you can use pv.claim() to easily create a bi-directional bounded claim.

Service

An abstract way to expose an application running on a set of Pods as a network service.

With Kubernetes you don’t need to modify your application to use an unfamiliar service discovery mechanism. Kubernetes gives Pods their own IP addresses and a single DNS name for a set of Pods, and can load-balance across them.

For example, consider a stateless image-processing backend which is running with 3 replicas. Those replicas are fungible—frontends do not care which backend they use. While the actual Pods that compose the backend set may change, the frontend clients should not need to be aware of that, nor should they need to keep track of the set of backends themselves. The Service abstraction enables this decoupling.

If you’re able to use Kubernetes APIs for service discovery in your application, you can query the API server for Endpoints, that get updated whenever the set of Pods in a Service changes. For non-native applications, Kubernetes offers ways to place a network port or load balancer in between your application and the backend Pods.

StatefulSet

StatefulSet is the workload API object used to manage stateful applications.

Manages the deployment and scaling of a set of Pods, and provides guarantees about the ordering and uniqueness of these Pods.

Like a Deployment, a StatefulSet manages Pods that are based on an identical container spec. Unlike a Deployment, a StatefulSet maintains a sticky identity for each of their Pods. These pods are created from the same spec, but are not interchangeable: each has a persistent identifier that it maintains across any rescheduling.

If you want to use storage volumes to provide persistence for your workload, you can use a StatefulSet as part of the solution. Although individual Pods in a StatefulSet are susceptible to failure, the persistent Pod identifiers make it easier to match existing volumes to the new Pods that replace any that have failed.

Using StatefulSets

StatefulSets are valuable for applications that require one or more of the following.

  • Stable, unique network identifiers.
  • Stable, persistent storage.
  • Ordered, graceful deployment and scaling.
  • Ordered, automated rolling updates.

List of initialization containers belonging to the pod.

Init containers are executed in order prior to containers being started. If any init container fails, the pod is considered to have failed and is handled according to its restartPolicy. The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion.

Init containers cannot currently be added ,removed or updated.

Volume

Volume represents a named volume in a pod that may be accessed by any container in the pod.

Docker also has a concept of volumes, though it is somewhat looser and less managed. In Docker, a volume is simply a directory on disk or in another Container. Lifetimes are not managed and until very recently there were only local-disk-backed volumes. Docker now provides volume drivers, but the functionality is very limited for now (e.g. as of Docker 1.7 only one volume driver is allowed per Container and there is no way to pass parameters to volumes).

A Kubernetes volume, on the other hand, has an explicit lifetime - the same as the Pod that encloses it. Consequently, a volume outlives any Containers that run within the Pod, and data is preserved across Container restarts. Of course, when a Pod ceases to exist, the volume will cease to exist, too. Perhaps more importantly than this, Kubernetes supports many types of volumes, and a Pod can use any number of them simultaneously.

At its core, a volume is just a directory, possibly with some data in it, which is accessible to the Containers in a Pod. How that directory comes to be, the medium that backs it, and the contents of it are determined by the particular volume type used.

To use a volume, a Pod specifies what volumes to provide for the Pod (the .spec.volumes field) and where to mount those into Containers (the .spec.containers[*].volumeMounts field).

A process in a container sees a filesystem view composed from their Docker image and volumes. The Docker image is at the root of the filesystem hierarchy, and any volumes are mounted at the specified paths within the image. Volumes can not mount onto other volumes

Workload

A workload is an application running on Kubernetes.

Whether your workload is a single component or several that work together, on Kubernetes you run it inside a set of pods. In Kubernetes, a Pod represents a set of running containers on your cluster.

ContainerLifecycle

Container lifecycle properties.

Initializer 

import org.cdk8s.plus31.ContainerLifecycle;

ContainerLifecycle.builder()
//  .postStart(Handler)
//  .preStop(Handler)
    .build();
postStartOptional 
public Handler getPostStart();

This hook is executed immediately after a container is created.

However, there is no guarantee that the hook will execute before the container ENTRYPOINT.

preStopOptional 
public Handler getPreStop();

This hook is called immediately before a container is terminated due to an API request or management event such as a liveness/startup probe failure, preemption, resource contention and others.

A call to the PreStop hook fails if the container is already in a terminated or completed state and the hook must complete before the TERM signal to stop the container can be sent. The Pod’s termination grace period countdown begins before the PreStop hook is executed, so regardless of the outcome of the handler, the container will eventually terminate within the Pod’s termination grace period. No parameters are passed to the handler.

The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion.

public Duration getTtlAfterFinished();
  • Type: org.cdk8s.Duration
  • Default: If this field is unset, the Job won’t be automatically deleted.

Limits the lifetime of a Job that has finished execution (either Complete or Failed).

If this field is set, after the Job finishes, it is eligible to be automatically deleted. When the Job is being deleted, its lifecycle guarantees (e.g. finalizers) will be honored. If this field is set to zero, the Job becomes eligible to be deleted immediately after it finishes. This field is alpha-level and is only honored by servers that enable the TTLAfterFinished feature.

scheduleRequired 
public Cron getSchedule();

Specifies the time in which the job would run again.

This is defined as a cron expression in the CronJob resource.

concurrencyPolicyOptional 
public ConcurrencyPolicy getConcurrencyPolicy();

Specifies the concurrency policy for the job.

failedJobsRetainedOptional 
public java.lang.Number getFailedJobsRetained();
  • Type: java.lang.Number
  • Default: 1

Specifies the number of failed jobs history retained.

This would retain the Job and the associated Pod resource and can be useful for debugging.

startingDeadlineOptional 
public Duration getStartingDeadline();

Kubernetes attempts to start cron jobs at its schedule time, but this is not guaranteed.

This deadline specifies how much time can pass after a schedule point, for which kubernetes can still start the job. For example, if this is set to 100 seconds, kubernetes is allowed to start the job at a maximum 100 seconds after the scheduled time.

Note that the Kubernetes CronJobController checks for things every 10 seconds, for this reason, a deadline below 10 seconds is not allowed, as it may cause your job to never be scheduled.

In addition, kubernetes will stop scheduling jobs if more than 100 schedules were missed (for any reason). This property also controls what time interval should kubernetes consider when counting for missed schedules.

For example, suppose a CronJob is set to schedule a new Job every one minute beginning at 08:30:00, and its startingDeadline field is not set. If the CronJob controller happens to be down from 08:29:00 to 10:21:00, the job will not start as the number of missed jobs which missed their schedule is greater than 100. However, if startingDeadline is set to 200 seconds, kubernetes will only count 3 missed schedules, and thus start a new execution at 10:22:00.

successfulJobsRetainedOptional 
public java.lang.Number getSuccessfulJobsRetained();
  • Type: java.lang.Number
  • Default: 3

Specifies the number of successful jobs history retained.

This would retain the Job and the associated Pod resource and can be useful for debugging.

suspendOptional 
public java.lang.Boolean getSuspend();
  • Type: java.lang.Boolean
  • Default: false

Specifies if the cron job should be suspended.

Only applies to future executions, current ones are remained untouched.

timeZoneOptional 
public java.lang.String getTimeZone();
  • Type: java.lang.String
  • Default: Timezone of kube-controller-manager process.

Specifies the timezone for the job.

This helps aligining the schedule to follow the specified timezone.

{@link https://en.wikipedia.org/wiki/List_of_tz_database_time_zones} for list of valid timezone values.

Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). Absolute number is calculated from percentage by rounding up. This can not be 0 if maxUnavailable is 0.

Example: when this is set to 30%, the new ReplicaSet can be scaled up immediately when the rolling update starts, such that the total number of old and new pods do not exceed 130% of desired pods. Once old pods have been killed, new ReplicaSet can be scaled up further, ensuring that total number of pods running at any time during the update is at most 130% of desired pods.

//  .metadata(ApiObjectMetadata)
//  .className(java.lang.String)
//  .defaultBackend(IngressBackend)
//  .rules(java.util.List<IngressRule>)
//  .tls(java.util.List<IngressTls>)
    .build();
metadataOptional 
public ApiObjectMetadata getMetadata();

Metadata that all persisted resources must have, which includes all objects users must create.

classNameOptional 
public java.lang.String getClassName();

Class Name for this ingress.

This field is a reference to an IngressClass resource that contains additional Ingress configuration, including the name of the Ingress controller.

defaultBackendOptional 
public IngressBackend getDefaultBackend();

The default backend services requests that do not match any rule.

Using this option or the addDefaultBackend() method is equivalent to adding a rule with both path and host undefined.

rulesOptional 
public java.util.List<IngressRule> getRules();

Routing rules for this ingress.

Each rule must define an IngressBackend that will receive the requests that match this rule. If both host and path are not specifiec, this backend will be used as the default backend of the ingress.

You can also add rules later using addRule(), addHostRule(), addDefaultBackend() and addHostDefaultBackend().

tlsOptional 
public java.util.List<IngressTls> getTls();

TLS settings for this ingress.

Using this option tells the ingress controller to expose a TLS endpoint. Currently the Ingress only supports a single TLS port, 443. If multiple members of this list specify different hosts, they will be multiplexed on the same port according to the hostname specified through the SNI TLS extension, if the ingress controller fulfilling the ingress supports SNI.

IngressRule

Represents the rules mapping the paths under a specified host to the related backend services.

Incoming requests are first evaluated for a host match, then routed to the backend associated with the matching path.

Initializer 

import org.cdk8s.plus31.IngressRule;

IngressRule.builder()
    .backend(IngressBackend)
//  .host(java.lang.String)
//  .path(java.lang.String)

public IngressBackend getBackend();

Backend defines the referenced service endpoint to which the traffic will be forwarded to.

hostOptional 
public java.lang.String getHost();
  • Type: java.lang.String
  • Default: If the host is unspecified, the Ingress routes all traffic based on the specified IngressRuleValue.

Host is the fully qualified domain name of a network host, as defined by RFC 3986.

Note the following deviations from the “host” part of the URI as defined in the RFC: 1. IPs are not allowed. Currently an IngressRuleValue can only apply to the IP in the Spec of the parent Ingress. 2. The : delimiter is not respected because ports are not allowed. Currently the port of an Ingress is implicitly :80 for http and :443 for https. Both these may change in the future. Incoming requests are matched against the host before the IngressRuleValue.

pathOptional 
public java.lang.String getPath();
  • Type: java.lang.String
  • Default: If unspecified, the path defaults to a catch all sending traffic to the backend.

Path is an extended POSIX regex as defined by IEEE Std 1003.1, (i.e this follows the egrep/unix syntax, not the perl syntax) 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 ‘/’.

pathTypeOptional 
public HttpIngressPathType getPathType();

Specify how the path is matched against request paths.

By default, path types will be matched by prefix.

https://kubernetes.io/docs/concepts/services-networking/ingress/#path-types

public java.util.List<java.lang.String> getHosts();
  • Type: java.util.List<java.lang.String>
  • Default: If unspecified, it defaults to the wildcard host setting for the loadbalancer controller fulfilling this Ingress.

Hosts are a list of hosts included in the TLS certificate.

The values in this list must match the name/s used in the TLS Secret.

secretOptional 
public ISecret getSecret();

Secret is the secret that contains the certificate and key used to terminate SSL traffic on 443.

If the SNI host in a listener conflicts with the “Host” header field used by an IngressRule, the SNI host is used for termination and value of the Host header is used for routing.

The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion.

Init containers cannot currently be added ,removed or updated.
