IPRuleSet

Scope: Cluster
Version: v1alpha1

This resource describes a set of rules (ip rule) that will be created on nodes with the appropriate labels.
  • spec
    object
    • spec.nodeSelector
      object

      Required value

      A set of labels that define the nodes on which these rules must be applied.
    • spec.rules
      array of objects

      Required value

      The desired set of rules (ip rule).
      • spec.rules.actions
        object
        A set of actions that must be performed with a packet that has the attributes described in the `selectors’ section.
        • spec.rules.actions.lookup
          object

          Required value

          Define the routing table in which the gateway address will be searched.
          • spec.rules.actions.lookup.ipRoutingTableID
            integer
            ID of the routing table on the node

            Allowed values: 1 <= X <= 4294967295

          • spec.rules.actions.lookup.routingTableName
            string
            The name of kubernetes resource RoutingTable in which the routing table ID will be searched.
      • spec.rules.priority
        integer

        The priority of the rule (the order of application depends on it).

        When choosing a number, it is worth considering several nuances:

        • All rules are sorted by node’s Linux network subsystem in order of priority (from lesser to greater) until a match is found.
        • If the packet falls under some rule, and the corresponding action has been successfully performed, then the search for rules termitated.
        • The default rule for searching the main routing table is 32766. In this case, if you specify a higher value, the rule will never be processed.

        Allowed values: 0 <= X <= 4294967295

      • spec.rules.selectors
        object

        A set of package attributes.

        If the package has the attributes described in the selectors section, then actions from the actions section will be applied to it.

        • spec.rules.selectors.dportRange
          object

          The range of destination ports.

          If there is only one port, then you can either fill in only the start field, or specify the same value in the start and end fields.

          • spec.rules.selectors.dportRange.end
            integer
            The end of the range.

            Allowed values: 0 <= X <= 65535

          • spec.rules.selectors.dportRange.start
            integer

            Required value

            The beginning of the range.

            Allowed values: 0 <= X <= 65535

        • spec.rules.selectors.from
          array of strings
          An array of subnets of the source.
          • spec.rules.selectors.from.Element of the array
            string
            The subnet of the source.
        • spec.rules.selectors.fwMark
          string
          The traffic label exists only inside the Linux network subsystem on the node.

          Pattern: ^0[xX][0-9a-fA-F]{1,8}(/0[xX][0-9a-fA-F]{1,8})?$

        • spec.rules.selectors.iif
          string
          The name of the incoming interface for the packet.
        • spec.rules.selectors.ipProto
          integer

          The number of the L4 protocol that is encapsulated in the IP in packet. The numbers of the most popular protocols are:

        • spec.rules.selectors.not
          boolean
          If this flag is specified, the rule will be inverted, that is, all packets that do not have the specified attributes will fall under it.

          Default: false

        • spec.rules.selectors.oif
          string
          The name of the outgoing interface for the packet.
        • spec.rules.selectors.sportRange
          object

          The range of source ports.

          If there is only one port, then you can either fill in only the start field, or specify the same value in the start and end fields.

          QOS traffic label (TOS, diffserv, dscp) transmitted over the network in the IP headers of the packet. Available values stored in the file /etc/iproute2/rt_dsfield.

          Pattern: ^0[xX][0-9a-fA-F]{1,2}$

        • spec.rules.selectors.uidRange
          object

          The range of UIDs (UserID) of applications that transmitting traffic.
