RemoteFS-GlusterFS+BatchPool

This recipe shows how to provision and link a Batch Pool with a GlusterFS storage cluster.

Configuration

Please see refer to this set of sample configuration files for this recipe.

Credentials Configuration

The credentials configuration should have management Azure Active Directory credentials defined along with a valid storage account. The management section can be supplied through environment variables instead if preferred.

Additionally, valid batch Azure Active Directory credentials should be supplied.

FS Configuration and GlusterFS storage cluster creation

Please follow the explanations as presented in vanilla RemoteFS-GlusterFS recipe. The RemoteFS storage cluster should be created first prior to creating the Batch pool.

Pool Configuration

Pool configuration would follow like most other standard non-linked pools except you will need a virtual network specification which would be the same virtual network hosting the RemoteFS file servers. The virtual_network property will require:

• name is the name of the virtual network to use
• resource_group is the resource group name containing the virtual network
• address_space is the address space of the virtual network
• subnet is the subnet for the compute nodes of this pool
  • name is the subnet name
  • address_prefix is the set of addresses for the batch nodes. This subnet space must be large enough to accommodate the number of compute nodes being allocated. Do not share subnets between RemoteFS storage clusters and Batch compute nodes.

Global Configuration

The global configuration is where the RemoteFS storage cluster is linked to the Batch pool through shared_data_volumes in volumes under global_resources. shared_data_volumes dictionary would have a key that is the storage cluster id key in FS configuration. For this example, this would be mystoragecluster. This property contains the following members:

• volume_driver should be set to storage_cluster to link the RemoteFS storage cluster to our Batch pool
• container_path is the container path to map the storage cluster mountpoint
• mount_options are any additional mount options to pass and can be empty or unspecified

Batch Shipyard Commands

After you have created your RemoteFS GlusterFS storage cluster via fs cluster add, then you can issue pool add with the above config which will create a Batch pool and automatically link your GlusterFS storage cluster against your Batch pool. You can then use data placed on the storage cluster in your containerized workloads.
