Red Hat OpenStack Platform 15 standalone

thumbnail for this post

If you need to deploy quickly a testing Red Hat Openstack Platform environment, you can use standalone deployment available since Red Hat OpenStack Platform 14.

Thanks to containers, this deployment will consume only one physical baremetal node. This standalone server will handle the control plane services and qemu/KVM compute services. This architecture is not using any nested virtualization and we can keep good Virtual Machine performance.

Official doc: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/15/html-single/quick_start_guide/index

Summary:

Prerequisites

Because we will deploy all the cluster on only one node, it's good to have at least 128GB of RAM and a SSD with enough IOPS.

For this deployment, we will use one Dell PowerEdge R740 with these specifications:

Dell PowerEdge R740

We can start by installing one default RHEL 8.1. Pick this ISO file “Red Hat Enterprise Linux 8.1 Binary DVD” here: https://access.redhat.com/downloads/content/479/ver=/rhel---8/8.1/x86_64/product-software

We will not describe how to install a standard RHEL 8.1 operating system, you can review the documentation if needed: https://access.redhat.com/documentation/fr-fr/red_hat_enterprise_linux/8/html/performing_a_standard_rhel_installation/index

We have now a running RHEL 8.1:

[root@stand0 ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux release 8.1 (Ootpa)

Prepare the environment

Create a stack user:

[root@stand0 ~]# useradd stack
[root@stand0 ~]# usermod -aG wheel stack
[root@stand0 ~]# echo "stack ALL=(root) NOPASSWD:ALL" | tee -a /etc/sudoers.d/stack
[root@stand0 ~]# chmod 0440 /etc/sudoers.d/stack

Register the node:

[stack@stand0 ~]$ sudo subscription-manager register --username myrhnaccount
Registering to: subscription.rhsm.redhat.com:443/subscription
Password: 
The system has been registered with ID: XXXXX-XXXXX-XXXX-XXXXX-XXXXXXX
The registered system name is: stand0.lan.redhat.com

[stack@stand0 ~]$ sudo subscription-manager attach --pool=XXXXXXXXXXXXXXXXXXXXX
Successfully attached a subscription for: RHN

[stack@stand0 ~]$ sudo subscription-manager repos --disable=*

Repository 'fast-datapath-for-rhel-8-x86_64-rpms' is enabled for this system.

Install the director command line interface:

[stack@stand0 ~]$ sudo yum install -y python3-tripleoclient

Prepare yaml configuration

Generate the containers-prepare-parameters.yaml file that contains the default ContainerImagePrepare parameters:

[stack@stand0 ~]$ openstack tripleo container image prepare default --output-env-file $HOME/containers-prepare-parameters.yaml

Add authentification information:

[stack@stand0 ~]$ sudo tee -a $HOME/containers-prepare-parameters.yaml << EOF 
  ContainerImageRegistryCredentials:
    registry.redhat.io:
      rhn_user: 'rhn_password'
EOF

Replace “rhn_user” by your user and “rhn_password” by your password:

[stack@stand0 ~]$ sed -i 's/rhn_user/myrhnaccount/' $HOME/containers-prepare-parameters.yaml
[stack@stand0 ~]$ sed -i 's/rhn_password/XXXXXXXXXXX/' $HOME/containers-prepare-parameters.yaml

Check the network configuration:

Use OpenStack client

Instead of sourcing an overcloudrc file, you just need to export an OS_CLOUD variable:

[stack@stand0 ~]$ export OS_CLOUD=standalone"

You can try ask for a token, OpenStack client is working \o/:

Boot an instance with the CLI

You can download a RHEL 8.1 KVM qcow2 guest image called “Red Hat Enterprise Linux 8.1 KVM Guest Image” here: https://access.redhat.com/downloads/content/479/ver=/rhel---8/8.1/x86_64/product-software :

[stack@stand0 ~]$ wget "https://access.cdn.redhat.com/content/origin/files/sha256/30/XXXXXXXXXX/rhel-8.1-x86_64-kvm.qcow2?user=XXXXXXXX&_auth_XXXXXXXX"

Create the RHEL 8.1 image in Glance:

[stack@stand0 ~]$ openstack image create rhel81 --file rhel-8.1-x86_64-kvm.qcow2 --disk-format qcow2 --container-format bare --public

You can get you overcloud password here:

[stack@stand0 ~]$ cat $HOME/undercloud-passwords.conf | grep undercloud_admin_password 
undercloud_admin_password: J0XXXXXXXX12abcdef

Prepare overcloudrc credential file (you can also download a RC file in Hozizon)

[stack@stand0 ~]$ cat <<EOF > $HOME/overcloudrc
