Creating QoS policies

Prerequisites

A clear understanding of QoS policy rules, which are explained in QoS policy rules.
To create a QoS policy as a system administrator, ensure that the environment file for this user is created, as described in Connecting to OpenStack command-line interface.
To create a QoS policy as a domain administrator, ensure that the environment file for this user is created, as instructed in Creating and assigning the quota manager role.

To create a QoS policy with rules

Create a QoS policy:
- If you are creating a policy as a system administrator
  1. Use the environment file for the system administrator:
    # source /etc/kolla/admin-openrc.sh
  2. Create a QoS policy within a project it will be applied to. For example:
    # openstack --insecure network qos policy create --project 3823a2d908ea4dd6909a8f93a6f66018 policy1
- If you are creating a policy as a domain administrator
  1. Use the environment file for the domain administrator. For example:
    # source domain-admin.sh
  2. Use the project name variable for the project where you want to create a QoS policy. For example:
    # export OS_PROJECT_NAME=testproject
  3. Create a QoS policy. For example:
    # openstack --insecure network qos policy create policy1

Create a rule for the QoS policy:

To create a bandwidth limit, specify bandwidth-limit for the --type option and specify rule parameters. For example, to limit the egress traffic to 3 Mbps, run:

# openstack --insecure network qos rule create --type bandwidth-limit \
--max-kbps 3000 --max-burst-kbits 2400 --egress policy1

To create a minimum bandwidth guarantee, specify minimum-bandwidth for the --type option and specify rule parameters. For example, to guarantee the minimum of 100 Kbps to the ingress traffic, run:

# openstack --insecure network qos rule create --type minimum-bandwidth \
--min-kbps 1000 --ingress policy1
