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.

import { DaemonSet } from 'cdk8s-plus-27'

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.

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.

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.

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.

ServiceAccount

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).

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.

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

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 
public readonly isolate: boolean;
  • Type: boolean

serviceAccountOptional 
public readonly serviceAccount: IServiceAccount;

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 
public readonly terminationGracePeriod: Duration;

Grace period until the pod is terminated.

volumesOptional 
public readonly volumes: Volume[];

selectOptional 
public readonly select: boolean;
  • Type: 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

ttlAfterFinishedOptional 
public readonly ttlAfterFinished: Duration;
  • Type: 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 readonly schedule: Cron;

Specifies the time in which the job would run again.

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

concurrencyPolicyOptional

failedJobsRetainedOptional 
public readonly failedJobsRetained: number;
  • Type: 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 readonly startingDeadline: Duration;

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 readonly successfulJobsRetained: number;
  • Type: 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 readonly suspend: boolean;
  • Type: boolean
  • Default: false

Specifies if the cron job should be suspended.

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

timeZoneOptional 
public readonly timeZone: string;
  • Type: string
  • Default: Timezone of kube-controller-manager process.

Specifies the timezone for the job.

This helps aligining the schedule to follow the specified timezone.

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.

Example: when this is set to 30%, the old ReplicaSet can be scaled down to 70% of desired pods immediately when the rolling update starts. Once new pods are ready, old ReplicaSet can be scaled down further, followed by scaling up the new ReplicaSet, ensuring that the total number of pods available at all times during the update is at least 70% of desired pods.

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

rulesOptional 
public readonly rules: IngressRule[];

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 readonly tls: IngressTls[];

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.

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 readonly path: string;
  • Type: 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 readonly pathType: HttpIngressPathType;

Specify how the path is matched against request paths.

By default, path types will be matched by prefix.

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.

Constants

HOSTNAME

A hostname represents a single node in the cluster.

https://kubernetes.io/docs/reference/labels-annotations-taints/#kubernetesiohostname

REGION

A region represents a larger domain, made up of one or more zones.

It is uncommon for Kubernetes clusters to span multiple regions. While the exact definition of a zone or region is left to infrastructure implementations, common properties of a region include higher network latency between them than within them, non-zero cost for network traffic between them, and failure independence from other zones or regions.

For example, nodes within a region might share power infrastructure (e.g. a UPS or generator), but nodes in different regions typically would not.

https://kubernetes.io/docs/reference/labels-annotations-taints/#topologykubernetesioregion

ZONE

A zone represents a logical failure domain.

It is common for Kubernetes clusters to span multiple zones for increased availability. While the exact definition of a zone is left to infrastructure implementations, common properties of a zone include very low network latency within a zone, no-cost network traffic within a zone, and failure independence from other zones. For example, nodes within a zone might share a network switch, but nodes in different zones should not.

REPLACE

This policy replaces the currently running job if a new job is being scheduled.

ConnectionScheme

HTTP

Use HTTP request for connecting to host.

HTTPS

Use HTTPS request for connecting to host.

DnsPolicy

Pod DNS policies.

CLUSTER_FIRST

Any DNS query that does not match the configured cluster domain suffix, such as “www.kubernetes.io”, is forwarded to the upstream nameserver inherited from the node. Cluster administrators may have extra stub-domain and upstream DNS servers configured.

CLUSTER_FIRST_WITH_HOST_NET

For Pods running with hostNetwork, you should explicitly set its DNS policy “ClusterFirstWithHostNet”.

DEFAULT

The Pod inherits the name resolution configuration from the node that the pods run on.

NONE

It allows a Pod to ignore DNS settings from the Kubernetes environment.

All DNS settings are supposed to be provided using the dnsConfig field in the Pod Spec.

EmptyDirMedium

The medium on which to store the volume.

DEFAULT

The default volume of the backing node.

MEMORY

Mount a tmpfs (RAM-backed filesystem) for you instead.

While tmpfs is very fast, be aware that unlike disks, tmpfs is cleared on node reboot and any files you write will count against your Container’s memory limit.

EnvFieldPaths

POD_NAMESPACE

The namespace of the pod.

POD_UID

The uid of the pod.

POD_LABEL

SERVICE_ACCOUNT_NAME

The service account name of the pod.

NODE_NAME

The name of the node.

NODE_IP

The ipAddress of the node.

POD_IPS

The ipAddresess of the pod.

FsGroupChangePolicy

ON_ROOT_MISMATCH

Only change permissions and ownership if permission and ownership of root directory does not match with expected permissions of the volume.

This could help shorten the time it takes to change ownership and permission of a volume

ALWAYS

Always change permission and ownership of the volume when volume is mounted.

HostPathVolumeType

Host path types.

DEFAULT

Empty string (default) is for backward compatibility, which means that no checks will be performed before mounting the hostPath volume.

DIRECTORY_OR_CREATE

If nothing exists at the given path, an empty directory will be created there as needed with permission set to 0755, having the same group and ownership with Kubelet.

DIRECTORY

A directory must exist at the given path.

FILE_OR_CREATE

If nothing exists at the given path, an empty file will be created there as needed with permission set to 0644, having the same group and ownership with Kubelet.

FILE

A file must exist at the given path.

SOCKET

A UNIX socket must exist at the given path.

CHAR_DEVICE

A character device must exist at the given path.

BLOCK_DEVICE

A block device must exist at the given path.

HttpIngressPathType

Specify how the path is matched against request paths.

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

PREFIX

Matches the URL path exactly.

EXACT

Matches based on a URL path prefix split by ‘/’.

IMPLEMENTATION_SPECIFIC

Matching is specified by the underlying IngressClass.

ImagePullPolicy

ALWAYS

Every time the kubelet launches a container, the kubelet queries the container image registry to resolve the name to an image digest.

If the kubelet has a container image with that exact digest cached locally, the kubelet uses its cached image; otherwise, the kubelet downloads (pulls) the image with the resolved digest, and uses that image to launch the container.

Default is Always if ImagePullPolicy is omitted and either the image tag is :latest or the image tag is omitted.

IF_NOT_PRESENT

The image is pulled only if it is not already present locally.

Default is IfNotPresent if ImagePullPolicy is omitted and the image tag is present but not :latest

NEVER

The image is assumed to exist locally.

No attempt is made to pull the image.

MountPropagation

NONE

This volume mount will not receive any subsequent mounts that are mounted to this volume or any of its subdirectories by the host.

In similar fashion, no mounts created by the Container will be visible on the host.

This is the default mode.

This mode is equal to private mount propagation as described in the Linux kernel documentation

HOST_TO_CONTAINER

This volume mount will receive all subsequent mounts that are mounted to this volume or any of its subdirectories.

In other words, if the host mounts anything inside the volume mount, the Container will see it mounted there.

Similarly, if any Pod with Bidirectional mount propagation to the same volume mounts anything there, the Container with HostToContainer mount propagation will see it.

This mode is equal to rslave mount propagation as described in the Linux kernel documentation

BIDIRECTIONAL

This volume mount behaves the same the HostToContainer mount.

In addition, all volume mounts created by the Container will be propagated back to the host and to all Containers of all Pods that use the same volume

A typical use case for this mode is a Pod with a FlexVolume or CSI driver or a Pod that needs to mount something on the host using a hostPath volume.

This mode is equal to rshared mount propagation as described in the Linux kernel documentation

Caution: Bidirectional mount propagation can be dangerous. It can damage the host operating system and therefore it is allowed only in privileged Containers. Familiarity with Linux kernel behavior is strongly recommended. In addition, any volume mounts created by Containers in Pods must be destroyed (unmounted) by the Containers on termination.

NetworkPolicyTrafficDefault

Default behaviors of network traffic in policies.

DENY

The policy denies all traffic.

Since rules are additive, additional rules or policies can allow specific traffic.

ALLOW

The policy allows all traffic (either ingress or egress).

Since rules are additive, no additional rule or policies can subsequently deny the traffic.

NetworkProtocol

Network protocols.

TCP

TCP.

UDP

UDP.

SCTP

SCTP.

PersistentVolumeAccessMode

Access Modes.

READ_WRITE_ONCE

The volume can be mounted as read-write by a single node.

ReadWriteOnce access mode still can allow multiple pods to access the volume when the pods are running on the same node.

READ_ONLY_MANY

The volume can be mounted as read-only by many nodes.

READ_WRITE_MANY

The volume can be mounted as read-write by many nodes.

READ_WRITE_ONCE_POD

The volume can be mounted as read-write by a single Pod.

Use ReadWriteOncePod access mode if you want to ensure that only one pod across whole cluster can read that PVC or write to it. This is only supported for CSI volumes and Kubernetes version 1.22+.

PersistentVolumeMode

Volume Modes.

FILE_SYSTEM

Volume is ounted into Pods into a directory.

If the volume is backed by a block device and the device is empty, Kubernetes creates a filesystem on the device before mounting it for the first time.

BLOCK

Use a volume as a raw block device.

Such volume is presented into a Pod as a block device, without any filesystem on it. This mode is useful to provide a Pod the fastest possible way to access a volume, without any filesystem layer between the Pod and the volume. On the other hand, the application running in the Pod must know how to handle a raw block device

PersistentVolumeReclaimPolicy

Reclaim Policies.

RETAIN

The Retain reclaim policy allows for manual reclamation of the resource.

When the PersistentVolumeClaim is deleted, the PersistentVolume still exists and the volume is considered “released”. But it is not yet available for another claim because the previous claimant’s data remains on the volume. An administrator can manually reclaim the volume with the following steps:

  1. Delete the PersistentVolume. The associated storage asset in external infrastructure (such as an AWS EBS, GCE PD, Azure Disk, or Cinder volume) still exists after the PV is deleted.
  2. Manually clean up the data on the associated storage asset accordingly.
  3. Manually delete the associated storage asset.

If you want to reuse the same storage asset, create a new PersistentVolume with the same storage asset definition.

DELETE

For volume plugins that support the Delete reclaim policy, deletion removes both the PersistentVolume object from Kubernetes, as well as the associated storage asset in the external infrastructure, such as an AWS EBS, GCE PD, Azure Disk, or Cinder volume.

Volumes that were dynamically provisioned inherit the reclaim policy of their StorageClass, which defaults to Delete. The administrator should configure the StorageClass according to users’ expectations; otherwise, the PV must be edited or patched after it is created

PodConnectionsIsolation

Isolation determines which policies are created when allowing connections from a a pod / workload to peers.

POD

Only creates network policies that select the pod.

PEER

Only creates network policies that select the peer.

PodManagementPolicy

Controls how pods are created during initial scale up, when replacing pods on nodes, or when scaling down.

The default policy is OrderedReady, where pods are created in increasing order (pod-0, then pod-1, etc) and the controller will wait until each pod is ready before continuing. When scaling down, the pods are removed in the opposite order.

The alternative policy is Parallel which will create pods in parallel to match the desired scale without waiting, and on scale down will delete all pods at once.

RestartPolicy

Restart policy for all containers within the pod.

ALWAYS

Always restart the pod after it exits.

ON_FAILURE

Only restart if the pod exits with a non-zero exit code.

NEVER

Never restart the pod.

ScalingStrategy

MAX_CHANGE

Use the policy that provisions the most changes.

MIN_CHANGE

Use the policy that provisions the least amount of changes.

~~DISABLED~~

  • Deprecated: - Omit the ScalingRule instead

Disables scaling in this direction.

ServiceType

For some parts of your application (for example, frontends) you may want to expose a Service onto an external IP address, that’s outside of your cluster.

Kubernetes ServiceTypes allow you to specify what kind of Service you want. The default is ClusterIP.

CLUSTER_IP

Exposes the Service on a cluster-internal IP.

Choosing this value makes the Service only reachable from within the cluster. This is the default ServiceType

NODE_PORT

Exposes the Service on each Node’s IP at a static port (the NodePort).

A ClusterIP Service, to which the NodePort Service routes, is automatically created. You’ll be able to contact the NodePort Service, from outside the cluster, by requesting :.

LOAD_BALANCER

Exposes the Service externally using a cloud provider’s load balancer.

NodePort and ClusterIP Services, to which the external load balancer routes, are automatically created.

EXTERNAL_NAME

Maps the Service to the contents of the externalName field (e.g. foo.bar.example.com), by returning a CNAME record with its value. No proxying of any kind is set up.

Note: You need either kube-dns version 1.7 or CoreDNS version 0.0.8 or higher to use the ExternalName type.

TaintEffect

Taint effects.

NO_SCHEDULE

This means that no pod will be able to schedule onto the node unless it has a matching toleration.

PREFER_NO_SCHEDULE

This is a “preference” or “soft” version of NO_SCHEDULE – the system will try to avoid placing a pod that does not tolerate the taint on the node, but it is not required.

NO_EXECUTE

This affects pods that are already running on the node as follows:.

Pods that do not tolerate the taint are evicted immediately. - Pods that tolerate the taint without specifying duration remain bound forever. - Pods that tolerate the taint with a specified duration remain bound for the specified amount of time.
