class avionix.kube.core.ServiceSpec(ports, cluster_ip=None, external_ips=None, external_name=None, external_traffic_policy=None, health_check_node_port=None, ip_family=None, load_balancer_ip=None, load_balancer_source_ranges=None, publish_not_ready_addresses=None, selector=None, session_affinity=None, session_affinity_config=None, topology_keys=None, type=None)
Parameters

  • ports (List[ServicePort]) – The list of ports that are exposed by this service. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies # noqa

  • cluster_ip (Optional[str]) – clusterIP is the IP address of the service and is usually assigned randomly by the master. If an address is specified manually and is not in use by others, it will be allocated to the service; otherwise, creation of the service will fail. This field can not be changed through updates. Valid values are “None”, empty string (“”), or a valid IP address. “None” can be specified for headless services when proxying is not required. Only applies to types ClusterIP, NodePort, and LoadBalancer. Ignored if type is ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies # noqa

  • external_ips (Optional[List[str]]) – externalIPs is a list of IP addresses for which nodes in the cluster will also accept traffic for this service. These IPs are not managed by Kubernetes. The user is responsible for ensuring that traffic arrives at a node with this IP. A common example is external load-balancers that are not part of the Kubernetes system.

  • external_name (Optional[str]) – externalName is the external reference that kubedns or equivalent will return as a CNAME record for this service. No proxying will be involved. Must be a valid RFC-1123 hostname (https://tools.ietf.org/html/rfc1123) and requires Type to be ExternalName.

  • external_traffic_policy (Optional[str]) – externalTrafficPolicy denotes if this Service desires to route external traffic to node-local or cluster-wide endpoints. “Local” preserves the client source IP and avoids a second hop for LoadBalancer and Nodeport type services, but risks potentially imbalanced traffic spreading. “Cluster” obscures the client source IP and may cause a second hop to another node, but should have good overall load-spreading.

  • health_check_node_port (Optional[int]) – healthCheckNodePort specifies the healthcheck nodePort for the service. If not specified, HealthCheckNodePort is created by the service api backend with the allocated nodePort. Will use user-specified nodePort value if specified by the client. Only effects when Type is set to LoadBalancer and ExternalTrafficPolicy is set to Local.

  • ip_family (Optional[str]) – ipFamily specifies whether this Service has a preference for a particular IP family (e.g. IPv4 vs. IPv6). If a specific IP family is requested, the clusterIP field will be allocated from that family, if it is available in the cluster. If no IP family is requested, the cluster’s primary IP family will be used. Other IP fields (loadBalancerIP, loadBalancerSourceRanges, externalIPs) and controllers which allocate external load-balancers should use the same IP family. Endpoints for this Service will be of this family. This field is immutable after creation. Assigning a ServiceIPFamily not available in the cluster (e.g. IPv6 in IPv4 only cluster) is an error condition and will fail during clusterIP assignment.

  • load_balancer_ip (Optional[str]) – Only applies to Service Type: LoadBalancer LoadBalancer will get created with the IP specified in this field. This feature depends on whether the underlying cloud-provider supports specifying the loadBalancerIP when a load balancer is created. This field will be ignored if the cloud-provider does not support the feature.

  • load_balancer_source_ranges (Optional[List[str]]) – If specified and supported by the platform, this will restrict traffic through the cloud-provider load-balancer will be restricted to the specified client IPs. This field will be ignored if the cloud-provider does not support the feature.” More info: https://kubernetes.io/docs/tasks/access-application-cluster/configure-cloud-provider-firewall/ # noqa

  • publish_not_ready_addresses (Optional[bool]) – publishNotReadyAddresses, when set to true, indicates that DNS implementations must publish the notReadyAddresses of subsets for the Endpoints associated with the Service. The default value is false. The primary use case for setting this field is to use a StatefulSet’s Headless Service to propagate SRV records for its Pods without respect to their readiness for purpose of peer discovery.

  • selector (Optional[dict]) – Route service traffic to pods with label keys and values matching this selector. If empty or not present, the service is assumed to have an external process managing its endpoints, which Kubernetes will not modify. Only applies to types ClusterIP, NodePort, and LoadBalancer. Ignored if type is ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/

  • session_affinity (Optional[str]) – Supports “ClientIP” and “None”. Used to maintain session affinity. Enable client IP based session affinity. Must be ClientIP or None. Defaults to None. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies # noqa

  • session_affinity_config (Optional[SessionAffinityConfig]) – sessionAffinityConfig contains the configurations of session affinity.

  • topology_keys (Optional[List[str]]) – topologyKeys is a preference-order list of topology keys which implementations of services should use to preferentially sort endpoints when accessing this Service, it can not be used at the same time as externalTrafficPolicy=Local. Topology keys must be valid label keys and at most 16 keys may be specified. Endpoints are chosen based on the first topology key with available backends. If this field is specified and all entries have no backends that match the topology of the client, the service has no backends for that client and connections should fail. The special value “*” may be used to mean “any topology”. This catch-all value, if used, only makes sense as the last value in the list. If this is not specified or empty, no topology constraints will be applied.

  • options are ExternalName, ClusterIP, NodePort, and LoadBalancer. "ExternalName" maps to the specified externalName. "ClusterIP" allocates a cluster-internal IP address for load-balancing to endpoints. Endpoints are determined by the selector or if that is not specified, by manual construction of an Endpoints object. If clusterIP is "None", no virtual IP is allocated and the endpoints are published as a set of endpoints rather than a stable IP. "NodePort" builds on ClusterIP and allocates a port on every node which routes to the clusterIP. "LoadBalancer" builds on NodePort and creates an external load-balancer (if supported in the current cloud) which routes to the clusterIP. More info (typeValid) – https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types # noqa

class avionix.kube.core.SessionAffinityConfig(client_ip)
Parameters

client_ip (ClientIPConfig) – clientIP contains the configurations of Client IP based session affinity.

class avionix.kube.core.StorageOSPersistentVolumeSource(fs_type, volume_name, volume_namespace, read_only=None, secret_ref=None)
Parameters

  • fs_type (str) – Filesystem type to mount. Must be a filesystem type supported by the host operating system. Ex. “ext4”, “xfs”, “ntfs”. Implicitly inferred to be “ext4” if unspecified.

  • volume_name (str) – VolumeName is the human-readable name of the StorageOS volume. Volume names are only unique within a namespace.

  • volume_namespace (str) – VolumeNamespace specifies the scope of the volume within StorageOS. If no namespace is specified then the Pod’s namespace will be used. This allows the Kubernetes name scoping to be mirrored within StorageOS for tighter integration. Set VolumeName to any name to override the default behaviour. Set to “default” if you are not using namespaces within StorageOS. Namespaces that do not pre-exist within StorageOS will be created.

  • read_only (Optional[bool]) – Defaults to false (read/write). ReadOnly here will force the ReadOnly setting in VolumeMounts.

  • secret_ref (Optional[ObjectReference]) – SecretRef specifies the secret to use for obtaining the StorageOS API credentials. If not specified, default values will be attempted.

  • volume_namespace (str) – VolumeNamespace specifies the scope of the volume within StorageOS. If no namespace is specified then the Pod’s namespace will be used. This allows the Kubernetes name scoping to be mirrored within StorageOS for tighter integration. Set VolumeName to any name to override the default behaviour. Set to “default” if you are not using namespaces within StorageOS. Namespaces that do not pre-exist within StorageOS will be created.

  • value (str) – Value of a property to set

class avionix.kube.core.TCPSocketAction(port, host=None)
Parameters

  • port (int) – Number or name of the port to access on the container. Number must be in the range 1 to 65535. Name must be an IANA_SVC_NAME.

  • host (Optional[str]) – Optional: Host name to connect to, defaults to the pod IP.

class avionix.kube.core.Taint(effect, key, time_added=None, value=None)
Parameters

  • effect (str) – Required. The effect of the taint on pods that do not tolerate the taint. Valid effects are NoSchedule, PreferNoSchedule and NoExecute.

  • key (str) – Required. The taint key to be applied to a node.

  • time_added (Optional[datetime]) – TimeAdded represents the time at which the taint was added. It is only written for NoExecute taints.

  • value (Optional[str]) – The taint value corresponding to the taint key.

class avionix.kube.core.Toleration(effect=None, key=None, toleration_seconds=None, value=None, operator=None)
Parameters

  • effect (Optional[str]) – Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.

  • key (Optional[str]) – Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.

  • toleration_seconds (Optional[int]) – TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.

  • value (Optional[str]) – Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.

  • operator (Optional[str]) – Operator represents a key’s relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.

class avionix.kube.core.TopologySelectorLabelRequirement(key, values)
Parameters

  • key (str) – The label key that the selector applies to.

  • values (List[str]) – An array of string values. One value must match the label to be selected. Each entry in Values is ORed.

class avionix.kube.core.TopologySelectorTerm(match_label_expressions)
Parameters

match_label_expressions (List[TopologySelectorLabelRequirement]) – A list of topology selector requirements by labels.

class avionix.kube.core.TopologySpreadConstraint(max_skew, topology_key, when_unsatisfiable, label_selector=None)
Parameters

  • max_skew (int) – MaxSkew describes the degree to which pods may be unevenly distributed. It’s the maximum permitted difference between the number of matching pods in any two topology domains of a given topology type. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 1/1/0: | zone1 | zone2 | zone3 | | P | P | | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 1/1/1; scheduling it onto zone1(zone2) would make the ActualSkew(2-0) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. It’s a required field. Default value is 1 and 0 is not allowed.

  • topology_key (str) – TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a “bucket”, and try to put balanced number of pods into each bucket. It’s a required field.

  • when_unsatisfiable (str) –

    WhenUnsatisfiable indicates how to deal with a pod if it doesn’t satisfy the spread constraint.

    • DoNotSchedule (default) tells the scheduler not to schedule it

    • ScheduleAnyway tells the scheduler to still schedule it It’s considered as
      ”Unsatisfiable” if and only if placing incoming pod on any topology

      violates “MaxSkew”. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P |

    If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won’t make it more imbalanced. It’s a required field.

  • label_selector (Optional[LabelSelector]) – LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain.

class avionix.kube.core.TypedLocalObjectReference(name, api_group=None)
Parameters

  • name (str) – Name is the name of resource being referenced

  • api_group (Optional[str]) – APIGroup is the group for the resource being referenced. If APIGroup is not specified, the specified Kind must be in the core API group. For any other third-party types, APIGroup is required.

  • read_only (Optional[bool]) – Mounted read-only if true, read-write otherwise (false or unspecified). Defaults to false.

  • sub_path (Optional[str]) – Path within the volume from which the container’s volume should be mounted. Defaults to “” (volume’s root).

  • sub_path_expr (Optional[str]) – Expanded path within the volume from which the container’s volume should be mounted. Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container’s environment. Defaults to “” (volume’s root). SubPathExpr and SubPath are mutually exclusive.
