provisioner

Documentation

Overview

provisioner contains the low level provisioners for handling the IP provisioning.

Currently there are three strategies defined:

• 'aws' - the operator will call AWS for random IP assignement.
• 'ocp-static' - the operator will manage which IPs are configured on which node.
• 'ocp-dynamic' - the operator will add the CIDR range to all matching hosts and OpenShift will manage the host IP networking.

Types

type EgressIPProvisioner

type EgressIPProvisioner interface {
	// FindHostForNewIP searches for a host in the failure domain to add an IP to.
	// Will return the hostname or an error.
	FindHostForNewIP(ctx context.Context, failureDomain string) (string, error)
	// AddSpecifiedIP adds a predefined IP to the specified host.
	// It will return an error or nil.
	AddSpecifiedIP(ctx context.Context, ip *net.IP, hostName string) error
	// AddRandomIP adds a random IP to the specified host.
	// It will return the IP or the error.
	AddRandomIP(ctx context.Context, hostName string) (*net.IP, error)
	// RemoveIP will remove the given IP from the specified host.
	// It will return an error or nil.
	RemoveIP(ctx context.Context, ip *net.IP, hostName string) error
	// MoveIP will move the specified IP from oldHost to newHost.
	// It will return an error or nil.
	MoveIP(ctx context.Context, ip *net.IP, oldHostName string, newHostName string) error
	// CheckIP will check if the specified IP is assigned on the specified host.
	// it will return an error or nil.
	CheckIP(ctx context.Context, ip *net.IP, hostName string) error
	// AssignCIDR will assign the cidr range to a host.
	// Basically it is only needed by the provisioner 'ocp-dynamic'. The other provisioners will be no-ops.
	AssignCIDR(ctx context.Context, hostName string) error
