cmd/k8s-operator,k8s-operator: allow users to configure proxy env vars via ProxyClass (#11743)
Adds new ProxyClass.spec.statefulSet.pod.{tailscaleContainer,tailscaleInitContainer}.Env field
that allow users to provide key, value pairs that will be set as env vars for the respective containers.
Allow overriding all containerboot env vars,
but warn that this is not supported and might break (in docs + a warning when validating ProxyClass).

    Name Type Description Required
    type string type indicates which kind of seccomp profile will be applied. Valid options are: Localhost - a profile defined in a file on the node should be used. RuntimeDefault - the container runtime default profile should be used. Unconfined - no profile should be applied.
    true
    localhostProfile string localhostProfile indicates a profile defined in a file on the node should be used. The profile must be preconfigured on the node to work. Must be a descending path, relative to the kubelet's configured seccomp profile location. Must be set if type is "Localhost". Must NOT be set for any other type.

    ProxyClass.spec.statefulSet.pod.tolerations[index]

    ↩ Parent

    The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator .

    Name Type Description Required
    effect string Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.
    false
    key string 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.
    false
    operator string 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.
    false
    tolerationSeconds integer 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.

    false
    observedGeneration integer If set, this represents the .metadata.generation that the condition was set based upon.
