[vpc]
section
Topics
Specifies Amazon VPC configuration settings.
The format is [vpc
. vpc-name
]vpc-name
must
start with a letter, contain no more than 30 characters, and only contain letters,
numbers, hyphens (-), and
underscores (_).
[vpc public] vpc_id =
vpc-xxxxxx
master_subnet_id =subnet-xxxxxx
additional_sg
(Optional) Provides an additional Amazon VPC security group Id for all instances.
There is no default value.
additional_sg =
sg-xxxxxx
compute_subnet_cidr
(Optional) Specifies a Classless Inter-Domain Routing (CIDR) block. Use this parameter if you want AWS ParallelCluster to create a compute subnet.
compute_subnet_cidr = 10.0.100.0/24
Update policy: If this setting is changed, the update is not allowed.
compute_subnet_id
(Optional) Specifies the ID of an existing subnet in which to provision the compute nodes.
If not specified, compute_subnet_id uses the value of master_subnet_id.
If the subnet is private, you must set up NAT for web access.
compute_subnet_id =
subnet-xxxxxx
Update policy: The compute fleet must be stopped for this setting to be changed for an update.
master_subnet_id
(Required) Specifies the ID of an existing subnet in which to provision the head node.
master_subnet_id =
subnet-xxxxxx
Update policy: If this setting is changed, the update is not allowed.
ssh_from
(Optional) Specifies a CIDR-formatted IP range to allow SSH access from.
This parameter is used only when AWS ParallelCluster creates the security group.
The default value is 0.0.0.0/0
.
ssh_from = 0.0.0.0/0
Update policy: This setting can be changed during an update.
use_public_ips
(Optional) Defines whether to assign public IP addresses to compute instances.
If set to true
, an Elastic IP address is associated to the head node.
If set to false
, the head node has a public IP (or not) according to the value of the "Auto-assign
Public IP" subnet configuration parameter.
For examples, see networking configuration.
The default value is true
.
use_public_ips = true
By default, all AWS accounts are limited to five (5) Elastic IP addresses for each Region. For more information, see Elastic IP address limit in Amazon EC2 User Guide for Linux Instances.
Update policy: The compute fleet must be stopped for this setting to be changed for an update.
vpc_id
(Required) Specifies the ID of the Amazon VPC in which to provision the cluster.
vpc_id =
vpc-xxxxxx
Update policy: If this setting is changed, the update is not allowed.
vpc_security_group_id
(Optional) Specifies the use of an existing security group for all instances.
There is no default value.
vpc_security_group_id =
sg-xxxxxx
The security group created by AWS ParallelCluster allows SSH access using port 22
from the addresses specified in
the ssh_from setting, or all IPv4 addresses (0.0.0.0/0
) if
the ssh_from setting isn't specified. If NICE DCV is enabled, then the
security group allows access to NICE DCV using port 8443 (or whatever the port setting specifies) from the addresses specified in the access_from setting, or all IPv4 addresses
(0.0.0.0/0
) if the access_from
setting isn't specified.
Update policy: This setting can be changed during an update.
