Types

type Cluster 

type Cluster struct {
	Waiter *wait.Waiter

	PortForwardOpts *PortForwardOptions
	// contains filtered or unexported fields
}

Cluster struct that models a k8s cluster for connect and disconnect commands.

func NewCluster 

func NewCluster(local, remote *factory.Factory) *Cluster

NewCluster returns a new cluster object. The cluster has to be initialized before being consumed.

func (*Cluster) CheckForeignCluster 

func (c *Cluster) CheckForeignCluster(ctx context.Context, remoteIdentity *discoveryv1alpha1.ClusterIdentity) (err error)

CheckForeignCluster retrieves the ForeignCluster resource associated with the remote cluster (if any), and stores it for later usage. Additionally, it performs the appropriate sanity checks, ensuring that the type of peering is not mutated.

func (*Cluster) DeleteForeignCluster 

func (c *Cluster) DeleteForeignCluster(ctx context.Context, remoteClusterID *discoveryv1alpha1.ClusterIdentity) error

DeleteForeignCluster deletes the foreignclusters instance for the given remote cluster.

func (*Cluster) DisablePeering 

func (c *Cluster) DisablePeering(ctx context.Context, remoteClusterID *discoveryv1alpha1.ClusterIdentity, incoming bool) (err error)

DisablePeering disables the peering for the remote cluster by patching the foreigncusters resource.

func (*Cluster) EnforceForeignCluster 

func (c *Cluster) EnforceForeignCluster(ctx context.Context, remoteClusterID *discoveryv1alpha1.ClusterIdentity,
	token, authURL, proxyURL string) error

EnforceForeignCluster enforces the presence of the foreignclusters instance for a given remote cluster. This function must be executed after CheckForeignCluster, which retrieves the ForeignCluster and performs the appropriate sanity checks. The newly created foreigncluster has the following fields set to:

  • ForeignAuthURL -> the remapped ip address for the local cluster of the auth service living in the remote cluster;
  • ForeignProxyURL -> the remapped ip address for the local cluster of the proxy service living in the remote cluster;
  • NetworkingEnabled -> No, we do not want the networking to be handled by the peering process. Networking is handled manually by the licoctl connect/disconnect commands.

func (*Cluster) EnforceIncomingPeeringFlag added in v0.10.2 

func (c *Cluster) EnforceIncomingPeeringFlag(ctx context.Context, remoteID *discoveryv1alpha1.ClusterIdentity, enabled bool) error

EnforceIncomingPeeringFlag sets the incoming peering flag for a given foreign cluster.

func (*Cluster) EnforceOutgoingPeeringFlag added in v0.7.0 

func (c *Cluster) EnforceOutgoingPeeringFlag(ctx context.Context, remoteID *discoveryv1alpha1.ClusterIdentity, enabled bool) error

EnforceOutgoingPeeringFlag sets the outgoing peering flag for a given foreign cluster.

func (*Cluster) ExchangeNetworkCfg 

func (c *Cluster) ExchangeNetworkCfg(ctx context.Context, remoteClusterID *discoveryv1alpha1.ClusterIdentity) error

ExchangeNetworkCfg creates the local networkconfigs resource for the remote cluster, replicates it into the remote cluster, waits for the remote cluster to populate the status of the resource and then sets the remote status in the local networkconfigs resource.

func (*Cluster) GetAuthToken 

func (c *Cluster) GetAuthToken() string

GetAuthToken returns the authentication token of the local cluster.

func (*Cluster) GetAuthURL 

func (c *Cluster) GetAuthURL() string

GetAuthURL returns the authentication URL of the local cluster.

func (*Cluster) GetClusterID 

func (c *Cluster) GetClusterID() *discoveryv1alpha1.ClusterIdentity

GetClusterID returns the cluster identity.

func (*Cluster) GetLocTenantNS 

func (c *Cluster) GetLocTenantNS() string

GetLocTenantNS returns the tenant namespace created for the remote cluster.

func (*Cluster) GetProxyURL 

func (c *Cluster) GetProxyURL() string

GetProxyURL returns the proxy URL of the local cluster.

func (*Cluster) Init 

func (c *Cluster) Init(ctx context.Context) error

Init initializes the cluster struct.

func (*Cluster) MapAuthIPForCluster 

func (c *Cluster) MapAuthIPForCluster(ctx context.Context, ipamClient ipam.IpamClient, remoteCluster *discoveryv1alpha1.ClusterIdentity) error

MapAuthIPForCluster maps the ClusterIP address of the local auth service on the local external CIDR as seen by the remote cluster.

func (*Cluster) MapProxyIPForCluster 

func (c *Cluster) MapProxyIPForCluster(ctx context.Context, ipamClient ipam.IpamClient, remoteCluster *discoveryv1alpha1.ClusterIdentity) error

MapProxyIPForCluster maps the ClusterIP address of the local proxy on the local external CIDR as seen by the remote cluster.

func (*Cluster) NewIPAMClient 

func (c *Cluster) NewIPAMClient(ctx context.Context) (ipam.IpamClient, error)

NewIPAMClient creates and returns a client to the IPAM service.

func (*Cluster) PortForwardIPAM 

func (c *Cluster) PortForwardIPAM(ctx context.Context) error

PortForwardIPAM starts the port forwarding for the IPAM service.

func (*Cluster) SetRemTenantNS 

func (c *Cluster) SetRemTenantNS(remTenantNamespace string)

SetRemTenantNS sets the tenant namespace of the local cluster created by the remote cluster.

func (*Cluster) SetUpTenantNamespace 

func (c *Cluster) SetUpTenantNamespace(ctx context.Context, remoteClusterID *discoveryv1alpha1.ClusterIdentity) error

SetUpTenantNamespace creates the tenant namespace in the local custer for the given remote cluster.

func (*Cluster) StopPortForwardIPAM 

func (c *Cluster) StopPortForwardIPAM()

StopPortForwardIPAM stops the port forwarding for the IPAM service.

func (*Cluster) TearDownTenantNamespace 

func (c *Cluster) TearDownTenantNamespace(ctx context.Context, remoteClusterID *discoveryv1alpha1.ClusterIdentity) error
