Implementation example

package p
import (
    "context"

    "github.com/BrunoReboul/ram/services/upload2gcs"
    "github.com/BrunoReboul/ram/utilities/ram"
)
var global upload2gcs.Global
var ctx = context.Background()

// EntryPoint is the function to be executed for each cloud function occurence
func EntryPoint(ctxEvent context.Context, PubSubMessage gps.PubSubMessage) error {
    return upload2gcs.EntryPoint(ctxEvent, PubSubMessage, &global)
}

func init() {
    upload2gcs.Initialize(ctx, &global)
}

Functions

func EntryPoint

func EntryPoint(ctxEvent context.Context, PubSubMessage gps.PubSubMessage, global *Global) error

EntryPoint is the function to be executed for each cloud function occurence

func Initialize

func Initialize(ctx context.Context, global *Global) (err error)

Initialize is to be executed in the init() function of the cloud function to optimize the cold start

Types

type Global

type Global struct {
	PubSubID string
	// contains filtered or unexported fields
}

Global structure for global variables to optimize the cloud function performances

type InstanceDeployment

type InstanceDeployment struct {
	DumpTimestamp time.Time `yaml:"dumpTimestamp"`
	Core          *deploy.Core
	Settings      struct {
		Service struct {
			GSU gsu.Parameters
			IAM iamgt.Parameters
			GCB gcb.Parameters
			GCF gcf.Parameters
		}
		Instance struct {
			GCF gcf.Event
		}
	}
}

InstanceDeployment settings and artifacts structure

func NewInstanceDeployment

func NewInstanceDeployment() *InstanceDeployment

NewInstanceDeployment create deployment structure with default settings set

func (*InstanceDeployment) Deploy

func (instanceDeployment *InstanceDeployment) Deploy() (err error)

Deploy a service instance

func (*InstanceDeployment) ReadValidate

func (instanceDeployment *InstanceDeployment) ReadValidate() (err error)

ReadValidate reads and validates service and instance settings

func (*InstanceDeployment) Situate

func (instanceDeployment *InstanceDeployment) Situate() (err error)

Situate complement settings taking in account the situation for service and instance settings
