Overview

Package secgroups provides the ability to manage security groups through the Nova API.

This API has been deprecated and will be removed from a future release of the Nova API service.

For environments that support this extension, this package can be used regardless of if either Neutron or nova-network is used as the cloud's network service.

Example to List Security Groups 

allPages, err := secroups.List(computeClient).AllPages()
if err != nil {
	panic(err)
}

allSecurityGroups, err := secgroups.ExtractSecurityGroups(allPages)
if err != nil {
	panic(err)
}

for _, sg := range allSecurityGroups {
	fmt.Printf("%+v\n", sg)
}

Example to List Security Groups by Server

	// FromGroupID represents another security group to allow access.
	// This is ONLY required if CIDR is blank. This value represents the ID of a
	// group that forwards traffic to the parent group. So, instead of accepting
	// network traffic from an entire IP range, you can instead refine the
	// inbound source by an existing security group.
