Types

type WzClient 

type WzClient struct {
	ID     int    `gorm:"primary_key"`
	Uid    string `gorm:"unique; not null"`
	Fqdn   string `gorm:"unique; not null"`
	RsaPk  string `gorm:"unique; not null"`
	RsaFp  string
	Status int `gorm:"not null"`
}

WzClient entity object for the database

func NewWzClient 

func NewWzClient() *WzClient

NewWzClient creates an instance of the WzClient

func NewWzClientFromPayload 

func NewWzClientFromPayload(payload map[string]interface{}) *WzClient

NewWzClientFromPayload creates an instance of the WzClient and fills-in with the payload

func (*WzClient) SetFingerprint 

func (wcl *WzClient) SetFingerprint() *WzClient

SetFingerprint calculates and sets the fingerprint from the RSA key

type WzControllerDbh 

type WzControllerDbh struct {
	// contains filtered or unexported fields
}

WzControllerDbh class bundle

func NewWzControllerDbh 

func NewWzControllerDbh() *WzControllerDbh

NewWzControllerDbh creates a new instances of the WzControllerDbh

func (*WzControllerDbh) GetClientsAPI 

func (wcd *WzControllerDbh) GetClientsAPI() *WzCtrlClientsAPI

GetClientsAPI returns an API bundle to access Client facility

func (*WzControllerDbh) GetKeysAPI 

func (wcd *WzControllerDbh) GetKeysAPI() *WzCtrlKeysAPI

GetKeysAPI returns an API bundle to store/retrieve/search for the PEM keys

func (*WzControllerDbh) SetDbh 

func (wcd *WzControllerDbh) SetDbh(dbh *gorm.DB)

SetDbh sets database handler to all the sub-objects

type WzCtrlClientsAPI 

type WzCtrlClientsAPI struct {
	wzlib_logger.WzLogger
	// contains filtered or unexported fields
}

Everything with client

func NewWzCtrlClientsAPI 

func NewWzCtrlClientsAPI() *WzCtrlClientsAPI

func (*WzCtrlClientsAPI) Accept 

func (wcc *WzCtrlClientsAPI) Accept(fingerprints ...string) (missing []string)

Accept that was already registered. Accepetation means flipping status and it will be "OK, now you are in". This makes client listable for the workers. But the reconciliation needs to be extra called elsewhere.

func (*WzCtrlClientsAPI) Delete 

func (wcc *WzCtrlClientsAPI) Delete(fingerprints ...string) (missing []string)

Delete just deletes everything of the client. This client is eligible to be registered again.

func (*WzCtrlClientsAPI) GetByFQDN 

func (wcc *WzCtrlClientsAPI) GetByFQDN()

GetByFQDN returns client data (struct?) by FQDN

func (*WzCtrlClientsAPI) GetByFp 

func (wcc *WzCtrlClientsAPI) GetByFp()

GetByFp returns client data (struct?) by RSA fingerprint

func (*WzCtrlClientsAPI) GetByUid 

func (wcc *WzCtrlClientsAPI) GetByUid()

GetByUid returns client data (struct?) by system ID

func (*WzCtrlClientsAPI) GetRegistered 

func (wcc *WzCtrlClientsAPI) GetRegistered() []*WzClient

GetRegistered returns a list of new clients

func (*WzCtrlClientsAPI) GetRegisteredAmount 

func (wcc *WzCtrlClientsAPI) GetRegisteredAmount() int64

GetRegisteredAmount returns an amout of registered clients

func (*WzCtrlClientsAPI) GetRejected 

func (wcc *WzCtrlClientsAPI) GetRejected() []*WzClient

GetRejected returns a list of new clients

func (*WzCtrlClientsAPI) Register 

func (wcc *WzCtrlClientsAPI) Register(client *WzClient) int

Register register a client that just appeared. Registration means "Your public RSA is in the database, now wait"

func (*WzCtrlClientsAPI) Reject 

func (wcc *WzCtrlClientsAPI) Reject(fingerprints ...string) (missing []string)

Reject sets its status as "rejected", but keeps in the database everything: FQDN, machine ID and RSA pubkey. Used for black-listing.

func (*WzCtrlClientsAPI) Search 

func (wcc *WzCtrlClientsAPI) Search(query string) []*WzClient

Search for clients based on specific query

func (*WzCtrlClientsAPI) Set 

func (wcc *WzCtrlClientsAPI) Set()

Set sets/updates/adds client's status (struct?). This does not include traits.

func (*WzCtrlClientsAPI) UpdateClientTraits 

func (wcc *WzCtrlClientsAPI) UpdateClientTraits()

UpdateTraits adds/sets/updates client's traits

type WzCtrlKeysAPI 

type WzCtrlKeysAPI struct {
	wzlib_logger.WzLogger
	// contains filtered or unexported fields
}

func NewWzCtrlKeysAPI 

func NewWzCtrlKeysAPI() *WzCtrlKeysAPI

func (*WzCtrlKeysAPI) AddRSAKeypairPEM 

func (wck *WzCtrlKeysAPI) AddRSAKeypairPEM(pub []byte, priv []byte, machineid string, fqdn string, owner string) error

func (*WzCtrlKeysAPI) AddRSAPublicPEM 

func (wck *WzCtrlKeysAPI) AddRSAPublicPEM(keypem []byte, machineid string, fqdn string, owner string) error

AddRSAPublicPEM returns client's RSA public key in PEM format, queried by the machine ID. the fqdn is to merely indicate what machine is holding it, but the key is tied up to the machine ID.

func (*WzCtrlKeysAPI) GetRSAPublicPEMByFingerprint 

func (wck *WzCtrlKeysAPI) GetRSAPublicPEMByFingerprint(fingerprint string) []byte

GetRSAPublicPEMByFingerprint returns a public key body

func (*WzCtrlKeysAPI) ListRSAPublicPEMByOwner 

func (wck *WzCtrlKeysAPI) ListRSAPublicPEMByOwner(owner string) []*WzPEMKeyEntity

ListRSAPublicPEM returns a list of registered public RSA keys, filtered by owner app.

func (*WzCtrlKeysAPI) RemoveRSAKeyPEM 

func (wck *WzCtrlKeysAPI) RemoveRSAKeyPEM(fingerprint string) error

RemoveRSAKeyPEM from the database by full fingerprint

type WzCtrlWorkersAPI 

type WzCtrlWorkersAPI struct {
	// contains filtered or unexported fields
}

func NewWzCtrlWorkersAPI 

func NewWzCtrlWorkersAPI() *WzCtrlWorkersAPI

func (*WzCtrlWorkersAPI) Activate 

func (cwa *WzCtrlWorkersAPI) Activate()

Activate a worker. This should return a reasonable timeout after which Reconcile() is called. If Activate is called again (new worker is in), then the previous timeout for the entire reconciliation is updated with this one

func (*WzCtrlWorkersAPI) Add 

func (cwa *WzCtrlWorkersAPI) Add()

Add worker to the cluster (keeps empty, needs reconciliation)

func (*WzCtrlWorkersAPI) AssignClients 

func (cwa *WzCtrlWorkersAPI) AssignClients()

AssignClients will assign clients to the worker

func (*WzCtrlWorkersAPI) Deactivate 

func (cwa *WzCtrlWorkersAPI) Deactivate()

Deactivate a worker (reconciles the cluster)

func (*WzCtrlWorkersAPI) GetAll 

func (cwa *WzCtrlWorkersAPI) GetAll()

GetAll workers

func (*WzCtrlWorkersAPI) GetAssignedClients 

func (cwa *WzCtrlWorkersAPI) GetAssignedClients()

GetAssignedClients per a worker

func (*WzCtrlWorkersAPI) Reconcile 

func (cwa *WzCtrlWorkersAPI) Reconcile()

Reconcile the whole cluster. This gets to each worker and reassigns clients to work with. Each worker works only with assigned clients and every time there might be a new clients, it never met before. Worker, essentially, a job proxy.

The reconsiliation algorithm is to shift as little as possible of clients, so only necessary machines are re-assigned to another worker.

func (*WzCtrlWorkersAPI) Remove 

func (cwa *WzCtrlWorkersAPI) Remove()

Remove worker from the cluster (unassign everything)

func (*WzCtrlWorkersAPI) UnassignClients 

func (cwa *WzCtrlWorkersAPI) UnassignClients()

UnassignClients from the worker

type WzPEMKeyEntity 

type WzPEMKeyEntity struct {
	ID         int    `gorm:"primary_key"`
	RsaFp      string `gorm:"unique; not null"`
	RsaPk      []byte `gorm:"unique; not null"`
	RsaPrivKey []byte
	MachineId  string `gorm:"unique"`
	Fqdn       string `gorm:"unique"`
	Owner      string `gorm:"not null"`
	Type       string `gorm:"not null"`
}
