Setting Up the Undercloud
Install the Undercloud
Use this example procedure to install the undercloud.
- Log in to the undercloud VM from the undercloud KVM host.
ssh ${undercloud_ip} - Configure the hostname.
undercloud_name=`hostname -s` undercloud_suffix=`hostname -d` hostnamectl set-hostname ${undercloud_name}.${undercloud_suffix} hostnamectl set-hostname --transient ${undercloud_name}.${undercloud_suffix} - Add the hostname to the /etc/hosts file. The following example assumes the management interface is
eth0.
undercloud_ip=`ip addr sh dev eth0 | grep "inet " | awk '{print $2}' | awk -F"/" '{print $1}'` echo ${undercloud_ip} ${undercloud_name}.${undercloud_suffix} ${undercloud_name} >> /etc/hosts - Set up the repositories.
CentOS
tripleo_repos=`python -c 'import requests;r = requests.get("https://trunk.rdoproject.org/centos7-queens/current"); print r.text ' | grep python2-tripleo-repos|awk -F"href=\"" '{print $2}' | awk -F"\"" '{print $1}'` yum install -y https://trunk.rdoproject.org/centos7-queens/current/${tripleo_repos} tripleo-repos -b queens currentRHEL
#Register with Satellite (can be done with CDN as well) satellite_fqdn=device.example.net act_key=xxx org=example yum localinstall -y http://${satellite_fqdn}/pub/katello-ca-consumer-latest.noarch.rpm subscription-manager register --activationkey=${act_key} --org=${org}
- Install the Tripleo client.
yum install -y python-tripleoclient tmux
- Copy the undercloud configuration file sample and modify
the configuration as required. See Red Hat documentation for information on how to modify that
file.
su - stack cp /usr/share/instack-undercloud/undercloud.conf.sample ~/undercloud.conf vi ~/undercloud.conf
- Install the undercloud.
openstack undercloud install source stackrc
Perform Post-Install Configuration
- Configure a forwarding path between the provisioning network
and the external network:
sudo iptables -A FORWARD -i br-ctlplane -o eth0 -j ACCEPT sudo iptables -A FORWARD -i eth0 -o br-ctlplane -m state --state RELATED,ESTABLISHED -j ACCEPT sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
- Add the external API interface:
sudo ip link add name vlan720 link br-ctlplane type vlan id 720 sudo ip addr add 10.2.0.254/24 dev vlan720 sudo ip link set dev vlan720 up
- Add the
stackuser to the docker group:newgrp docker exit su - stack source stackrc
- Change admin password for overcloud.
(undercloud) [stack@queensa contrail]$ pwd /home/stack/tripleo-heat-templates/environments/contrail (undercloud) [stack@queensa contrail]$ vi contrail-services.yaml parameter_defaults: AdminPassword: <password>
- Add contrail-subcluster.yaml, contrail-ips-from-pool-all.yaml
and contrail-scheduler-hints.yaml to the OpenStack deploy command:
openstack overcloud deploy --templates ~/tripleo-heat-templates \ -e ~/overcloud_images.yaml \ -e ~/tripleo-heat-templates/environments/network-isolation.yaml \ -e ~/tripleo-heat-templates/environments/contrail/contrail-plugins.yaml \ -e ~/tripleo-heat-templates/environments/contrail/contrail-services.yaml \ -e ~/tripleo-heat-templates/environments/contrail/contrail-net.yaml \ -e ~/tripleo-heat-templates/environments/contrail/contrail-subcluster.yaml \ -e ~/tripleo-heat-templates/environments/contrail/contrail-ips-from-pool-all.yaml \ -e ~/tripleo-heat-templates/environments/contrail/contrail-scheduler-hints.yaml \ --roles-file ~/tripleo-heat-templates/roles_data_contrail_aio.yaml
