Deploy Openstack using Openstack Helm Infra scripts

Readme is under construction. I just added small into about how to deploy Openstack infra as multi node using ansible playbook.

Before you start

Those playbooks can deploy:

• Airskiff with Minikube (export MINIKUBE=true)
• Airskiff with normall Kubernetes controller + additional node
• Openstack Helm + additional node using Openstack Helm + Openstack Helm Infra scripts
• Airship Armada on one host using Openstack Helm Infra script
• Execute Openstack Tempest test on this infra

IMPORTANT NOTE

Currently tempest tests uses FLAT network type. Please make sure, that network addressation in bridge_network role is same as prepare_tempest.sh script has.

Clone and install Ansible

NOTE: prefered system is Ubuntu 18.04.

sudo apt update
sudo apt install -y git python3-pip python3-dev
git clone https://github.com/danpawlik/openstack-helm-deployment
sudo pip install -r requirements.txt

Preparation

1. Create ssh id_rsa_ansible key in $HOME/.ssh/id_rsa_ansible location. This key will be used by Ansible to add that key into Openstack VMs.

NOTE: Please add also this key into authorized_keys on the Ansible server.

Example:

ssh-keygen -trsa -b 2048 -o $HOME/.ssh/id_rsa_ansible

2. Add into .ssh/config information, that Ansible can use the id_rsa_ansible key, e.g.:

Host *
    User ubuntu
    IdentityFile ~/.ssh/id_rsa_ansible

Example: how to deploy Airskiff with K8S controller + one node

1. Check "local inventory" in the playbook, how it is defined, e.g.:

  vars:
    k8s_hosts:
      k8s_contr:
        - some_contr
      k8s_minion:
        - some_minion
        - some_minion

2. You can also set more minions and contr (if you want) but 1 for each is a minimum value.

To set the name, you can just export variables:

export CONTR_NAME=airskiff_contr-1
export MINION_1_NAME=airskiff-minion-1
export MINION_2_NAME=airskiff-minion-2
export OPENSTACK_KEYPAIR_NAME=ansible_key

3. Now you need to read openrc file, because playbooks will read credentials ans spawn VMs.

source openrc

3 a). Additionaly spawn ssh-agent and export variable:

eval $(ssh-agent -s)
ssh-add <YOUR KEY>
export ANSIBLE_SSH_COMMON_ARGS="-o ForwardAgent=yes -o ControlMaster=auto -o ControlPersist=60s "

4. Now you just need to execute Ansible playbook:

• for Airskiff:

export ANSIBLE_HOST_KEY_CHECKING=False
export TREASUREMAP_OVERWRITE=true
export NAMESPACE=testns
export USE_SHIPYARD_ACTION=true # in this case, 100-custom-deploy-osh.sh will be used instead of 100-deploy-osh.sh
export SETUP_AIRSKIFF=true
export VRACK_NET_NAME=vrack     # If you use OVH public cloud, create vrack (optional - tempest can communicate with VMs)

• for Openstack Helm:

export ANSIBLE_HOST_KEY_CHECKING=False
export SETUP_OSH=true
# If you use OVH public cloud, create vrack (optional - tempest can communicate with VMs)
export VRACK_NET_NAME=vrack

Then execute ansible playbooks:

ansible-playbook playbooks/osh-deploy-cluster.yaml -vv
ansible-playbook playbooks/osh-deploy-openstack.yaml -vv

NOTE: Available export variables:

export OPENSTACK_KEYPAIR_NAME=ansible_key

export CONTR_NAME=bob_contr
export MINION_1_NAME=stevard_minion_1
export MINION_2_NAME=kevin_minion

export KUBE_VERSION=1.13.4 # it doesn't work when SETUP_MINIKUBE is true
export SETUP_MINIKUBE=false

export DOCKER_REPO_NAME=
export DOCKER_REPO_LOGIN=
export DOCKER_REPO_PASSWORD=

TREASUREMAP_OVERWRITE=true # overwrite airskiff site manifests

# if you want to add new SSH key to authorized_keys, set path to the pub key
export ADDITIONAL_SSH_KEY=

If you want to change images of Glance, Nova and Neutron to custom:

export TREASUREMAP_PARAMS="{
'NOVA_IMAGE':'docker.io/openstackhelm/nova:stein-ubuntu_bionic',
'NEUTRON_IMAGE':'docker.io/openstackhelm/neutron:stein-ubuntu_bionic',
'KEYSTONE_IMAGE':'docker.io/openstackhelm/keystone:stein-ubuntu_bionic',
'GLANCE_IMAGE': 'docker.io/openstackhelm/glance:stein-ubuntu_bionic',
'HEAT_IMAGE':'docker.io/openstackhelm/heat:stein-ubuntu_bionic',
'LIBVIRT_IMAGE': 'docker.io/openstackhelm/libvirt:latest-ubuntu_bionic',
'OPENSTACK_RELEASE': 'stein' }"

If you want to use OpenvSwitch with DPDK, just add into TREASUREMAP_PARAMS:

'OPENVSWITCH_IMAGE': 'docker.io/openstackhelm/openvswitch:latest-ubuntu_bionic-dpdk',

Just for Openstack Helm multinode playbook:

OSH_EXTRA_HELM_ARGS
OSH_EXTRA_HELM_ARGS_BARBICAN
OSH_EXTRA_HELM_ARGS_CEPH_DEPLOY
OSH_EXTRA_HELM_ARGS_CEPH_NS_ACTIVATE
OSH_EXTRA_HELM_ARGS_CINDER
OSH_EXTRA_HELM_ARGS_GLANCE
OSH_EXTRA_HELM_ARGS_HEAT
OSH_EXTRA_HELM_ARGS_INGRESS_KUBE_SYSTEM
OSH_EXTRA_HELM_ARGS_KEYSTONE
OSH_EXTRA_HELM_ARGS_LIBVIRT
OSH_EXTRA_HELM_ARGS_MARIADB
OSH_EXTRA_HELM_ARGS_MEMCACHED
OSH_EXTRA_HELM_ARGS_NEUTRON
OSH_EXTRA_HELM_ARGS_NOVA
OSH_EXTRA_HELM_ARGS_RABBITMQ

To run tempest tests:

OPENRC_PATH='/home/ubuntu/openrc'
ansible-playbook playbooks/tempest-run.yaml

Please note, that repo and scripts are still under construction.
