kind string EMQX
metadata ObjectMeta Refer to Kubernetes API documentation for fields of metadata.
spec EMQXSpec Spec defines the desired identities of EMQX nodes in this set.

Field Description Default Validation
nodeSelector object (keys:string, values:string) NodeSelector is a selector which must be true for the pod to fit on a node. Selector which must match a node's labels for the pod to be scheduled on that node.
More info: https://kubernetes.io/docs/concepts/configuration/assign-pod-node/
nodeName string NodeName is a request to schedule this pod onto a specific node. If it is non-empty, the scheduler simply schedules this pod onto that node, assuming that it fits resource requirements.
affinity Affinity Affinity for pod assignment
ref: https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity
toleRations Toleration array If specified, the pod's tolerations.
The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator .
replicas integer Replicas is the desired number of replicas of the given Template.
These are replicas in the sense that they are instantiations of the
same Template, but individual replicas also have a consistent identity.
If unspecified, defaults to 3.
3
command string array Entrypoint array. Not executed within a shell.
The container image's ENTRYPOINT is used if this is not provided.
Variable references $(VAR_NAME) are expanded using the container's environment. If a variable
cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced
to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will
produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless
of whether the variable exists or not. Cannot be updated.
More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell
args string array Arguments to the entrypoint.
The container image's CMD is used if this is not provided.

More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell
ports ContainerPort array List of ports to expose from the container. Exposing a port here gives
the system additional information about the network connections a
container uses, but is primarily informational. Not specifying a port here
DOES NOT prevent that port from being exposed. Any port which is
listening on the default "0.0.0.0" address inside a container will be
accessible from the network.
Cannot be updated.
env EnvVar array List of environment variables to set in the container.
Cannot be updated.
envFrom EnvFromSource array List of sources to populate environment variables in the container.
The keys defined within a source must be a C_IDENTIFIER. All invalid keys
will be reported as an event when the container is starting. When a key exists in multiple
sources, the value associated with the last source will take precedence.
Values defined by an Env with a duplicate key will take precedence.
Cannot be updated.
resources ResourceRequirements Compute Resources required by this container.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
podSecurityContext PodSecurityContext SecurityContext holds pod-level security attributes and common container settings.
Optional: Defaults to empty. See type description for default values of each field.
containerSecurityContext SecurityContext SecurityContext defines the security options the container should be run with.
If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext.
More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/
initContainers Container array 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 or removed.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/
extraContainers Container array ExtraContainers represents extra containers to be added to the pod.
See emqx#252
extraVolumes Volume array See emqx#72
extraVolumeMounts VolumeMount array See emqx#72
livenessProbe Probe Periodic probe of container liveness.
Container will be restarted if the probe fails.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
readinessProbe Probe Periodic probe of container service readiness.
Container will be removed from service endpoints if the probe fails.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
startupProbe Probe StartupProbe indicates that the Pod has successfully initialized.
If specified, no other probes are executed until this completes successfully.
If this probe fails, the Pod will be restarted, just as if the livenessProbe failed.
This can be used to provide different probe parameters at the beginning of a Pod's lifecycle,
when it might take a long time to load data or warm a cache, than during steady-state operation.
This cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
lifecycle Lifecycle Actions that the management system should take in response to container lifecycle events.
Cannot be updated.
volumeClaimTemplates PersistentVolumeClaimSpec VolumeClaimTemplates is a list of claims that pods are allowed to reference.
The StatefulSet controller is responsible for mapping network identities to
claims in a way that maintains the identity of a pod. Every claim in
this list must have at least one matching (by name) volumeMount in one
container in the template. A claim in this list takes precedence over
any volumes in the template, with the same name.
