Using Helm Charts to Provision All-in-One Contrail with OpenStack Ocata

System Specifications

This procedure uses Helm to provision an OpenStack Ocata Contrail all-in-one cluster without high availability.

This procedure is tested with:

• Operating system: Ubuntu 16.04.3 LTS

• Kernel: 4.4.0-87-generic

• Docker: 1.13.1-cs9

• Helm: v2.7.2

• Kubernetes: v1.8.3

• OpenStack: Ocata

This setup was tested on a system with the following specifications:

• CPU: 8

• RAM: 32 GB

• HDD: 120 GB

Installation Steps

1. Get the contrail-helm-deployer.

   From Juniper Networks, download contrail-helm-deployer-5.0.0-0.40.tgz onto your provisioning host.

   • Untar contrail-helm-deployer-5.0.0-0.40.tgz.

     tar -zxf contrail-helm-deployer-5.0.0-0.40.tgz -C /opt/

2. Export required variables.

   content_copy zoom_out_map

   export BASE_DIR=$(pwd)
   export OSH_PATH=${BASE_DIR}/openstack-helm
   export OSH_INFRA_PATH=${BASE_DIR}/openstack-helm-infra
   export CHD_PATH=${BASE_DIR}/contrail-helm-deployerExport variables 

3. Install necessary packages and deploy Kubernetes.

   Note:

   If you want to install a different version of Kubernetes, CNI, or Calico, edit ${OSH_INFRA_PATH}/tools/gate/devel/local-vars.yaml to override the default values in ${OSH_INFRA_PATH}/tools/gate/playbooks/vars.yaml.

   content_copy zoom_out_map

   cd ${OSH_PATH}
   ./tools/deployment/developer/common/001-install-packages-opencontrail.sh
   ./tools/deployment/developer/common/010-deploy-k8s.sh

4. Install OpenStack and the Heat client.

   content_copy zoom_out_map

   ./tools/deployment/developer/common/020-setup-client.sh
   

5. Deploy OpenStack Helm-related charts.

   content_copy zoom_out_map

   ./tools/deployment/developer/nfs/031-ingress-opencontrail.sh
   ./tools/deployment/developer/nfs/040-nfs-provisioner.sh
   ./tools/deployment/developer/nfs/050-mariadb.sh
   ./tools/deployment/developer/nfs/060-rabbitmq.sh
   ./tools/deployment/developer/nfs/070-memcached.sh
   ./tools/deployment/developer/nfs/080-keystone.sh
   ./tools/deployment/developer/nfs/100-horizon.sh
   ./tools/deployment/developer/nfs/120-glance.sh
   ./tools/deployment/developer/nfs/151-libvirt-opencontrail.sh
   ./tools/deployment/developer/nfs/161-compute-kit-opencontrail.sh

6. Deploy Contrail Helm charts.

   content_copy zoom_out_map

   cd $CHD_PATH
   
   make
   
   # Set the IP of your CONTROL_NODES (specify your control data ip, if you have one)
   export CONTROL_NODES=10.87.65.245
   # set the control data network cidr list separated by comma and set the respective gateway
   export CONTROL_DATA_NET_LIST=10.87.65.128/25
   export VROUTER_GATEWAY=10.87.65.129
   
   kubectl label node opencontrail.org/controller=enabled --all
   kubectl label node opencontrail.org/vrouter-kernel=enabled --all
   
   kubectl replace -f ${CHD_PATH}/rbac/cluster-admin.yaml
   
   tee /tmp/contrail.yaml << EOF
   global:
     contrail_env:
       CONTROLLER_NODES: 172.17.0.1
       CONTROL_NODES: ${CONTROL_NODES}
       LOG_LEVEL: SYS_NOTICE
       CLOUD_ORCHESTRATOR: openstack
       AAA_MODE: cloud-admin
       CONTROL_DATA_NET_LIST: ${CONTROL_DATA_NET_LIST}
       VROUTER_GATEWAY: ${VROUTER_GATEWAY}
   EOF
   
   helm install --name contrail ${CHD_PATH}/contrail \
   --namespace=contrail --values=/tmp/contrail.yaml

7. Deploy Heat charts.

   content_copy zoom_out_map

   cd ${OSH_PATH}
   ./tools/deployment/developer/nfs/091-heat-opencontrail.sh
