nf-core/configs: googlebatch
Google Cloud Batch API Profile
nf-core/configs: googlebatch Configuration
To be used with the googlebatch profile by specifying the -profile googlebatch when running nf-core pipelines.
project id and workdir bucket need to be supplied with params.project_id, params.workdir_bucket .
Required Parameters
--project_id
Project id of the project where compute resources will be created
--workdir_bucket
Cloud Storage Bucket to be used for the workdir
Optional Parameters
--location
The region where compute resources will be provisioned. If not specified, it will default to us-central1.
--use_spot
Defines which provisioning model to be used. When set to false, standard VM instances will be used. Defaults to true.
--boot_disk
Defines the size of boot disk on compute instances. Defaults to 100GB.
--workers_service_account
Defines which service account will be used by Compute instances running the pipeline. If not specified, the default compute service account of the project will be used.
--use_private_ip
Defines whether real IP addresses will be assigned to compute instance runningn the pipeline. Defaults to false. If set to true a Cloud NAT needs to be provisioned on the same VPC to enable workers to access the Internet to download any necessary artifacts such as container images or communicate with Tower if it is configured. It is recommeneded to use private IP addresses.
--custom_vpc
If you don’t want to use the default VPC network or if it is not available, you need to specify both the custom_vpc and the custom_subnet. Custom VPC should be in this format global/networks/[custom_VPC].
--custom_subnet
When custom_vpc is specified, you must also specify the custom_subnet. Custom subnet should be in this format regions/[GCP_Region]/subnetworks/[custom_subnet].
Gogole Batch Setup
Please refer to the Nextflow documentation which describe how to setup the Google Cloud environment.
