Overview ¶
This package was generated from the schema defined at /references/worker-manager/v1/api.json This service manages workers, including provisioning for dynamic worker pools.
Methods interacting with a provider may return a 503 response if that provider has not been able to start up, such as if the service to which it interfaces has an outage. Such requests can be retried as for any other 5xx response.
See:
How to use this package ¶
First create a WorkerManager object:
workerManager := tcworkermanager.New(nil)
and then call one or more of workerManager's methods, e.g.:
err := workerManager.Ping(.....)
handling any errors...
if err != nil { // handle error... }

Actions provide a generic mechanism to expose additional features of a provisioner, worker type, or worker to Taskcluster clients.
An action is comprised of metadata describing the feature it exposes, together with a webhook for triggering it.
The Taskcluster tools site, for example, retrieves actions when displaying provisioners, worker types and workers. It presents the provisioner/worker type/worker specific actions to the user. When the user triggers an action, the web client takes the registered webhook, substitutes parameters into the URL (see `url`), signs the requests with the Taskcluster credentials of the user operating the web interface, and issues the HTTP request.
The level to which the action relates (provisioner, worker type, worker) is called the action context. All actions, regardless of the action contexts, are registered against the provisioner when calling `queue.declareProvisioner`.
The action context is used by the web client to determine where in the web interface to present the action to the user as follows:
| `context` | Tool where action is displayed | |-------------|--------------------------------| | provisioner | Provisioner Explorer | | worker-type | Workers Explorer | | worker | Worker Explorer |
See [actions docs](/docs/reference/platform/taskcluster-queue/docs/actions) for more information.

type WorkerManager ¶
func New ¶
func New(credentials *tcclient.Credentials, rootURL string) *WorkerManager
New returns a WorkerManager client, configured to run against production. Pass in nil credentials to create a client without authentication. The returned client is mutable, so returned settings can be altered.
workerManager := tcworkermanager.New( nil, // client without authentication "http://localhost:1234/my/taskcluster", // taskcluster hosted at this root URL on local machine ) err := workerManager.Ping(.....) // for example, call the Ping(.....)

func (*WorkerManager) ListWorkers ¶
func (workerManager *WorkerManager) ListWorkers(provisionerId, workerType, continuationToken, limit, quarantined, workerState string) (*ListWorkersResponse, error)
Stability: *** EXPERIMENTAL ***
Get a list of all active workers of a workerType.
`listWorkers` allows a response to be filtered by quarantined and non quarantined workers, as well as the current state of the worker. To filter the query, you should call the end-point with one of [`quarantined`, `workerState`] as a query-string option with a true or false value.
The response is paged. If this end-point returns a `continuationToken`, you should call the end-point again with the `continuationToken` as a query-string option. By default this end-point will list up to 1000 workers in a single page. You may limit this with the query-string parameter `limit`.
Required scopes:
worker-manager:list-workers:<provisionerId>/<workerType>
See #listWorkers
func (*WorkerManager) ListWorkersForWorkerGroup ¶
func (workerManager *WorkerManager) ListWorkersForWorkerGroup(workerPoolId, workerGroup, continuationToken, limit string) (*WorkerListInAGivenWorkerPool, error)

func (*WorkerManager) Ping ¶
func (workerManager *WorkerManager) Ping() error
Respond without doing anything. This endpoint is used to check that the service is up.
See #ping
func (*WorkerManager) RegisterWorker ¶
func (workerManager *WorkerManager) RegisterWorker(payload *RegisterWorkerRequest) (*RegisterWorkerResponse, error)
Register a running worker. Workers call this method on worker start-up.
This call both marks the worker as running and returns the credentials the worker will require to perform its work. The worker must provide some proof of its identity, and that proof varies by provider type.
See #registerWorker
func (*WorkerManager) RemoveWorker ¶
func (workerManager *WorkerManager) RemoveWorker(workerPoolId, workerGroup, workerId string) error
Remove an existing worker. The precise behavior of this method depends on the provider implementing the given worker. Some providers do not support removing workers at all, and will return a 400 error. Others may begin removing the worker, but it may remain available via the API (perhaps even in state RUNNING) afterward.
Required scopes:
worker-manager:remove-worker:<workerPoolId>/<workerGroup>/<workerId>
See #removeWorker
func (*WorkerManager) ReportWorkerError ¶
func (workerManager *WorkerManager) ReportWorkerError(workerPoolId string, payload *WorkerErrorReport) (*WorkerPoolError, error)
Report an error that occurred on a worker. This error will be included with the other errors in `listWorkerPoolErrors(workerPoolId)`.
Workers can use this endpoint to report startup or configuration errors that might be associated with the worker pool configuration and thus of interest to a worker-pool administrator.
NOTE: errors are publicly visible. Ensure that none of the content contains secrets or other sensitive information.
Required scopes:
All of: * assume:worker-pool:<workerPoolId> * assume:worker-id:<workerGroup>/<workerId>
See #reportWorkerError
func (*WorkerManager) ReregisterWorker ¶
func (workerManager *WorkerManager) ReregisterWorker(payload *ReregisterWorkerRequest) (*ReregisterWorkerResponse, error)
Stability: *** EXPERIMENTAL ***
Reregister a running worker.
This will generate and return new Taskcluster credentials for the worker on that instance to use. The credentials will not live longer the `registrationTimeout` for that worker. The endpoint will update `terminateAfter` for the worker so that worker-manager does not terminate the instance.
Required scopes:
worker-manager:reregister-worker:<workerPoolId>/<workerGroup>/<workerId>
See #reregisterWorker
func (*WorkerManager) UpdateWorker ¶
func (workerManager *WorkerManager) UpdateWorker(workerPoolId, workerGroup, workerId string, payload *WorkerCreationUpdateRequest) (*WorkerFullDefinition, error)
Update an existing worker in-place. Like `createWorker`, this is only useful for worker pools where the provider does not create workers automatically. This method allows updating all fields in the schema unless otherwise indicated in the provider documentation. See the documentation for the individual providers, and in particular the [static provider](https://docs.taskcluster.net/docs/reference/core/worker-manager/) for more information.
Required scopes:
worker-manager:update-worker:<workerPoolId>/<workerGroup>/<workerId>
See #updateWorker
func (*WorkerManager) UpdateWorkerPool ¶
func (workerManager *WorkerManager) UpdateWorkerPool(workerPoolId string, payload *WorkerPoolDefinition1) (*WorkerPoolFullDefinition, error)
Stability: *** EXPERIMENTAL ***
Given an existing worker pool definition, this will modify it and return the new definition.
To delete a worker pool, set its `providerId` to `"null-provider"`. After any existing workers have exited, a cleanup job will remove the worker pool. During that time, the worker pool can be updated again, such as to set its `providerId` to a real provider.
Required scopes:
All of: * worker-manager:manage-worker-pool:<workerPoolId> * worker-manager:provider:<providerId>
See #updateWorkerPool

Fields that are defined by a user for a worker pool. Used to create worker-pool definitions. There is a larger set of fields for viewing since some parts are generated by the service.
type WorkerPoolDefinition1 ¶
type WorkerPoolDefinition1 struct { // Additional properties allowed Config json.RawMessage `json:"config"` // Ignored on update Created tcclient.Time `json:"created,omitempty"` // A description of this worker pool. // // Max length: 10240 Description string `json:"description"` // If true, the owner should be emailed on provisioning errors EmailOnError bool `json:"emailOnError"` // Ignored on update LastModified tcclient.Time `json:"lastModified,omitempty"` // An email address to notify when there are provisioning errors for this // worker pool.
