Multinode¶

Overview¶

In order to drive towards a production-ready OpenStack solution, our goal is to provide containerized, yet stable persistent volumes that Kubernetes can use to schedule applications that require state, such as MariaDB (Galera). Although we assume that the project should provide a „batteries included“ approach towards persistent storage, we want to allow operators to define their own solution as well. Examples of this work will be documented in another section, however evidence of this is found throughout the project. If you find any issues or gaps, please create a story to track what can be done to improve our documentation.

Bemerkung

Please see the supported application versions outlined in the source variable file.

Other versions and considerations (such as other CNI SDN providers), config map data, and value overrides will be included in other documentation as we explore these options further.

The installation procedures below, will take an administrator from a new kubeadm installation to OpenStack-Helm deployment.

Bemerkung

Many of the default container images that are referenced across OpenStack-Helm charts are not intended for production use; for example, while LOCI and Kolla can be used to produce production-grade images, their public reference images are not prod-grade. In addition, some of the default images use latest or master tags, which are moving targets and can lead to unpredictable behavior. For production-like deployments, we recommend building custom images, or at minimum caching a set of known images, and incorporating them into OpenStack-Helm via values overrides.

Warnung

Until the Ubuntu kernel shipped with 16.04 supports CephFS subvolume mounts by default the HWE Kernel is required to use CephFS.

Kubernetes Preparation¶

You can use any Kubernetes deployment tool to bring up a working Kubernetes cluster for use with OpenStack-Helm. For production deployments, please choose (and tune appropriately) a highly-resilient Kubernetes distribution, e.g.:

Airship, a declarative open cloud infrastructure platform
KubeADM, the foundation of a number of Kubernetes installation solutions

For a lab or proof-of-concept environment, the OpenStack-Helm gate scripts can be used to quickly deploy a multinode Kubernetes cluster using KubeADM and Ansible. Please refer to the deployment guide here.

Managing and configuring a Kubernetes cluster is beyond the scope of OpenStack-Helm and this guide.

Deploy OpenStack-Helm¶

Bemerkung

The following commands all assume that they are run from the /opt/openstack-helm directory.

Setup Clients on the host and assemble the charts¶

The OpenStack clients and Kubernetes RBAC rules, along with assembly of the charts can be performed by running the following commands:

#!/bin/bash
sudo -H -E pip3 install \
  -c${UPPER_CONSTRAINTS_FILE:=https://releases.openstack.org/constraints/upper/${OPENSTACK_RELEASE:-stein}} \
  cmd2 python-openstackclient python-heatclient --ignore-installed

sudo -H mkdir -p /etc/openstack
sudo -H chown -R $(id -un): /etc/openstack
FEATURE_GATE="tls"; if [[ ${FEATURE_GATES//,/ } =~ (^|[[:space:]])${FEATURE_GATE}($|[[:space:]]) ]]; then
  tee /etc/openstack/clouds.yaml << EOF
  clouds:
    openstack_helm:
      region_name: RegionOne
      identity_api_version: 3
      cacert: /etc/openstack-helm/certs/ca/ca.pem
      auth:
        username: 'admin'
        password: 'password'
        project_name: 'admin'
        project_domain_name: 'default'
        user_domain_name: 'default'
        auth_url: 'https://keystone.openstack.svc.cluster.local/v3'
EOF
else
  tee /etc/openstack/clouds.yaml << EOF
  clouds:
    openstack_helm:

        user_domain_name: 'default'
        auth_url: 'http://keystone.openstack.svc.cluster.local/v3'
EOF
fi

#NOTE: Build helm-toolkit, most charts depend on helm-toolkit
make helm-toolkit

Alternatively, this step can be performed by running the script directly:

./tools/deployment/multinode/010-setup-client.sh

#NOTE: Display info

Alternatively, this step can be performed by running the script directly:

OSH_DEPLOY_MULTINODE=True ./tools/deployment/component/common/ingress.sh

Create loopback devices for CEPH¶

Create two loopback devices for ceph as one disk for OSD data and other disk for block DB and block WAL. If loop0 and loop1 devices are busy in your case , feel free to change them in parameters by using –ceph-osd-data and –ceph-osd-dbwal options.

ansible all -i /opt/openstack-helm-infra/tools/gate/devel/multinode-inventory.yaml -m shell -s -a "/opt/openstack-helm/tools/deployment/common/setup-ceph-loopback-device.sh --ceph-osd-data /dev/loop0 --ceph-osd-dbwal /dev/loop1"

Deploy Ceph¶

The script below configures Ceph to use loopback devices created in previous step as backend for ceph osds. To configure a custom block device-based backend, please refer to the ceph-osd values.yaml.

Additional information on Kubernetes Ceph-based integration can be found in the documentation for the CephFS and RBD storage provisioners, as well as for the alternative NFS provisioner.

Warnung

The upstream Ceph image repository does not currently pin tags to specific Ceph point releases. This can lead to unpredictable results in long-lived deployments. In production scenarios, we strongly recommend overriding the Ceph images to use either custom built images or controlled, cached images.

Bemerkung

The ./tools/deployment/multinode/kube-node-subnet.sh script requires docker to run.

Configuring OpenStack for a particular production use-case is beyond the scope of this guide. Please refer to the OpenStack Configuration documentation for your selected version of OpenStack to determine what additional values overrides should be provided to the OpenStack-Helm charts to ensure appropriate networking, security, etc. is in place.
