initializeCloudProvider: Initialize the service provider

In DockerParallel: Using the Docker Container to Create R Workers on Local or Cloud Platform

Description

Initialize the service provider. This function will be called prior to runDockerServer and runDockerWorkers. It is used to initialize the cloud-specific settings(e.g. Initialize the cloud network). The function might be called many times. Developers can cache the cloud status and speed up the initialization process.

Usage

initializeCloudProvider(provider, cluster, verbose)

## S4 method for signature 'ANY'
initializeCloudProvider(provider, cluster, verbose = 0L)

Arguments

provider	S4 CloudProvider object. The service provider.
cluster	S4 DockerCluster object.
verbose	Integer. The verbose level, default 1.

Details

Based on the cloud nature, an initialization process might be required before deploying the container on the cloud. This function will be called by the DockerCluster object before running the server and workers. The default method will do nothing.

Besides initializing the cloud settings, if the server container will be deployed by the cloud provider. The function should call .setServerWorkerSameLAN to inform the DockerCluster object whether the server and the workers are under the same router. If .getServerWorkerSameLAN returns TRUE(default), the worker will connect to the server using the server's private IP. Otherwise, the server's public IP will be used.

Although it is possible to change any settings in the cluster object in this function, the best practice is to only initialize provider and the value serverWorkerSameLAN.

Value

No return value

Functions
