d2g
d2g is a go library for converting legacy Docker Worker tasks into native Generic Worker tasks.
This library is used internally by Generic Worker, in order to run tasks that were originally intended for Docker Worker. On detecting that a claimed task has a Docker Worker payload, Generic Worker will first convert it to its own native format before validating and executing the task.
For users wishing to convert Docker Worker tasks to Generic Worker tasks at
source, please see the taskcluster d2g
cli subcommand.

Functions ¶
func ConvertScopes ¶
func ConvertScopes( dwScopes []string, dwPayload *dockerworker.DockerWorkerPayload, taskQueueID string, scopeExpander scopes.ScopeExpander, ) (gwScopes []string, err error)
ConvertScopes takes a slice of Docker Worker task scopes and returns a slice of equivalent Generic Worker scopes. These scopes should be used together with a converted Docker Worker task payload (see d2g.Convert function) to run Docker Worker tasks under Generic Worker.
func ConvertTaskDefinition ¶
func ConvertTaskDefinition( dwTaskDef json.RawMessage, config map[string]any, scopeExpander scopes.ScopeExpander, directoryReader func(string) ([]os.DirEntry, error), ) (json.RawMessage, error)
Types ¶
type ConversionInfo ¶
type ConversionInfo struct {
ContainerName string
CopyArtifacts []CopyArtifact
Image Image
}
func ConvertPayload ¶
func ConvertPayload( dwPayload *dockerworker.DockerWorkerPayload, config map[string]any, directoryReader func(string) ([]os.DirEntry, error), ) (gwPayload *genericworker.GenericWorkerPayload, conversionInfo ConversionInfo, err error)
ConvertPayload transforms a Docker Worker task payload into an equivalent Generic Worker Multiuser POSIX task payload. The resulting Generic Worker payload is a BASH script which uses Docker (by default) to contain the Docker Worker payload. Since scopes fall outside of the payload in a task definition, scopes need to be converted separately (see d2g.ConvertScopes function).
