The RuntimeClass is used to determine which container runtime is used to run all containers in a pod.
RuntimeClasses are manually defined by a user or cluster provisioner, and referenced in the PodSpec.
The Kubelet is responsible for resolving the RuntimeClassName reference before running the pod.
For more details, see https://kubernetes.io/docs/concepts/containers/runtime-class/
handler specifies the underlying runtime and configuration that the CRI implementation will use to handle pods of this class.
The possible values are specific to the node & CRI configuration.
It is assumed that all handlers are available on every node, and handlers of the same name are equivalent on every node.
For example, a handler called "runc" might specify that the runc OCI runtime (using native Linux containers) will be used to run the containers in a pod.
The Handler must be lowercase, conform to the DNS Label (RFC 1123) requirements, and is immutable.
Returns the relative, descendent directory path between this module and other.
Throws if no such path exists.
For example, if module mod1 has path /dir1/mod1.pkl, and module mod2 has path /dir1/dir2/dir3/mod2.pkl,
then mod1.relativePathTo(mod2) will return List("dir2", "dir3").
A common use case is to compute the directory path between a template located at the root of a hierarchy
(say rootModule.pkl) and the currently evaluated module (accessible via the module keyword):
FieldsV1 stores a set of fields in a data structure like a Trie, in JSON format.
Each key is either a '.' representing the field itself, and will always map to an empty set, or a string representing a sub-field or item.
The string will follow one of these four formats:
'f:', where is the name of a field in a struct, or key in a map
'v:', where is the exact json formatted value of a list item
'i:', where is position of a item in a list
'k:', where is a map of a list item's key fields to their unique values
If a key maps to an empty Fields value, the field that key represents is part of the set.
The exact format is defined in sigs.k8s.io/structured-merge-diff.
RuntimeClass defines a class of container runtime supported in the cluster.
