Tripleo Standalone deployment

Steps

Provision VM

$ git clone -b centos8 https://gitlab.cee.redhat.com/akahat/ansible-kvm-vm.git
$ sudo dnf install virt-manager qemu-kvm virt-install libguestfs-tools-c -y
$ sudo dnf update -y
$ sudo reboot
$ virtualenv ~/.venv
$ . ~/.venv/bin/activate
$ pip install ansible
$ ansible-playbook ~/ansible-kvm-vm/playbooks/standalone_centos8_dual_nic_playbook.yml

Or
Create new vm using ISO.

wget  http://mirrors.piconets.webwerks.in/centos-mirror/8.1.1911/isos/x86_64/CentOS-8.1.1911-x86_64-dvd1.iso
sudo virt-install -n CentOS8_tripleo --os-type=Linux --os-variant="centos7.0" --ram=8192 --vcpus=5 --disk path=/var/lib/libvirt/images/CentOS8_Tripleo.qcow2,bus=virtio,size=50 --graphics none --cdrom /root/CentOS-8.1.1911-x86_64-dvd1.iso --network network=default,network=management --print-xml > centos8.xml
virsh define --file /root/centos8.xml

Inside VM

dnf install -y libibverbs.so.1 libmlx5 vim  mod_http2
useradd stack
echo "redhat" | passwd stack --stdin
echo "stack ALL=(root) NOPASSWD:ALL" | tee -a /etc/sudoers.d/stack
rm -rf /etc/sysconfg/network-scripts/ifcfg-ens3
sudo systemctl restart network

Add containers_prepare_parameters.yaml

$ cat containers-prepare-parameters.yaml

Add standalone_parameters.yaml

$ cat standalone_parameters.yaml

Run openstack tripleo deploy command
Order of the parameters matters.

sudo openstack  tripleo deploy \
--templates /usr/share/openstack-tripleo-heat-templates/ \
--standalone --yes --output-dir /home/stack/logs/ \
--standalone-role Standalone --timeout 90 \
-e /usr/share/openstack-tripleo-heat-templates/environments/standalone/standalone-tripleo.yaml \
-e /home/stack/containers_prepare_parameters.yaml \
-e /home/stack/standalone_parameters.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/low-memory-usage.yaml \
-e /usr/share/openstack-tripleo-heat-templates/ci/environments/scenario012-standalone.yaml \
-r /usr/share/openstack-tripleo-heat-templates/roles/Standalone.yaml \
--deployment-user stack \
--local-ip 192.168.24.1/24 2>&1 | tee -a /home/stack/standalone_deploy.log

If needed to deploy with some scenario files you can add the following parameters:

-e /usr/share/openstack-tripleo-heat-templates/ci/environments/scenario012-standalone.yaml

Deploy standalone using tripleo-operator-ansible

Install tripleo-operator-ansible and ansible in the vm

sudo dnf -y install tripleo-operator-ansible ansible

copy the following playbook in the vm

        tripleo_deploy_output_dir: "{{ ansible_env.HOME }}"

Note: Include vm ip in the standalone_dns and make sure you run all operations in tmux

Run the above playbook

$ ansible-playbook standalone.yaml

It will fail after installing and configuring tripleo-repos and system update. We need to re-run the above playbook

you can view the standalone deploy log in

$ tail -f ~/standalone_deploy.log

You can view the tripleo-container-image-prepare.log

$ tail -f /var/log/tripleo-container-image-prepare.log

Note it will get stuck as connectivity giving no new service error to outer world gets lost, all traffic needs to go through eth0 network interface. so we need to restart the network server and make sure ping to outside is working

$ sudo systemctl restart network
$ ping google.com

Let's re-run the deployment, you can find the playbooks generated via config_download in ~/standalone-ansible-<hash> dir and re-run it

$ cd ~/standalone-ansible-<hash>
$ ansible-playbook --become -i inventory.yaml config-download/deploy_steps_playbook.yaml

It will restart the deployment and you are done.

Once deployment finishes, we can verify the deployment

$ sudo su
# export OS_CLOUD=standalone
