EMQXCoreTemplateSpec

Appears in:

• EMQXCoreTemplate

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/config/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/config/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 . TODO: should use tolerations instead, this field just for compatible with old version, will delete in future.
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 .
topologySpreadConstraints TopologySpreadConstraint array	// TopologySpreadConstraint specifies how to spread matching pods among the given topology.
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. Defaults to 2.	2
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. 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
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/config/manage-resources-containers/
podSecurityContext PodSecurityContext	SecurityContext holds pod-level security attributes and common container settings.	{ fsGroup:1000 fsGroupChangePolicy:Always runAsGroup:1000 runAsUser:1000 supplementalGroups:[1000] }
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/	{ runAsGroup:1000 runAsNonRoot:true runAsUser:1000 }
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 https://github.com/emqx/emqx-operator/issues/252
extraVolumes Volume array	See https://github.com/emqx/emqx-operator/pull/72
extraVolumeMounts VolumeMount array	See https://github.com/emqx/emqx-operator/pull/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	{ failureThreshold:3 httpGet:map[path:/status port:dashboard] initialDelaySeconds:60 periodSeconds:30 }
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	{ failureThreshold:12 httpGet:map[path:/status port:dashboard] initialDelaySeconds:10 periodSeconds:5 }
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. More than EMQXReplicantTemplateSpec
