How to Upgrade From Contrail Networking Release 3.x or 4.x with RHOSP10 to Contrail Networking Release 1907 with RHOSP13

date_range 28-Aug-23

arrow_backward

arrow_forward

The goal of this topic is to provide a combined procedure to upgrade Red Hat OpenStack Platform (RHOSP) from RHOSP 10 to RHOSP 13 by leveraging Red Hat Fast Forward Upgrade (FFU) procedure while simultaneously upgrading Contrail Networking from Release 4.1.x to Release 1907. The procedure leverages the In Service Software Upgrade (ISSU) procedure from Contrail to minimize the downtime.

The downtime will be reduced by not requiring extra server reboots in addition to the ones that the RHOSP FFU procedure already requires for Kernel/RHEL upgrades.

Refer to Red Hat OpenStack Platform 13 Fast Forward Upgrades for details on RHOSP 10 to RHOSP 13 Fast Forward Upgrade (FFU) procedure of OpenStack Platform environment from one long life version to the next long life version.

Note:

This procedure is also applicable for upgrading Contrail Networking Release 3.x or 4.x with RHOSP10 to Contrail Networking Release 5.1.x with RHOSP13.

When to Use This Procedure

We recommend engaging Juniper Networking professional services for assistance with performing this procedure.

This procedure is used when you are running Contrail Networking Release 3 or Contrail Networking Release 4 in an environment using Red Hat Openstack Platform 10 (RHOSP 10) for orchestration and want to upgrade your environment to a Contrail Networking 19 release using RHOSP13. The procedure leverages the Red Hat Fast Forward Upgrade (FFU) procedure for the RHOSP upgrade and the In Service Software Upgrade (ISSU) procedure for the Contrail Networking upgrade.

The procedure in this document has been validated for the following Contrail Networking upgrade scenarios:

If you want to use this procedure to upgrade your Contrail Networking release to other releases, you must engage Juniper Networks professional services. Contact your Juniper representative for additional information.

Before You Begin

Access ContrailImageTag located at README Access to Contrail Registry 19XX.

Note:

You must enable FFU RedHat subscription for overcloud nodes as the upgrade involves yum update which needs RPM repositories enabled. The subscription must include access to both OSP10 and OSP13 repositories (rhel-7-server-openstack-13-rpms). Additionally, the subscription must have access to the repo rhel-server-rhscl-7-rpms repository. ISSU node uses python27-python-pip from this repository.

ISSU nodes must have internet access during installation to install docker-compose via pip.

If you do not have internet access, after ISSU node installation, you must download required packages manually an a node with internet access, transfer packages on all the ISSU nodes and install them.

Upgrading Contrail Networking Release 3.x or 4.x with RHOSP10 to Contrail Networking Release 1907 with RHOSP13

Follow chapter 2 from step 2.1 through step 2.8 of Red Hat OpenStack Platform 13 Fast Forward Upgrades to prepare for an Openstack Platform Upgrade.

Note:
Do not reboot the compute nodes as mentioned in step 2.9.
Prepare to deploy Contrail In-Service Software Upgrade (ISSU) node.
1. Update Contrail TripleO Heat Templates (Stable/Newton branch) from https://github.com/Juniper/contrail-tripleo-heat-templates.
2. Update Contrail TripleO Puppet module to the latest version and prepare Swift Artifacts.
  mkdir -p ~/usr/share/openstack-puppet/modules/tripleo git clone -b stable/newton https://github.com/Juniper/contrail-tripleo-puppet usr/share/openstack-puppet/modules/tripleo tar czvf puppet-modules.tgz usr/ upload-swift-artifacts -c contrail-artifacts -f puppet-modules.tgz
3. Prepare docker registry with Contrail Networking R1907 images. It can be undercloud or a separate node.
  In addition to Contrail Networking images, the required ansible deployer image is contrail-kolla-ansible-deployer which is available at https://hub.docker.com/r/opencontrailnightly/contrail-kolla-ansible-deployer/tags.
  
  You must use the same tag as of other Contrail Networking containers.
  
  To prepare images:
  
  contrail-tripleo-heat-templates/tools/contrail/import_contrail_container_docker.sh
  
  For details on building container, refer to https://github.com/Juniper/contrail-deployers-containers.
Deploy Contrail In-Service Software Upgrade (ISSU) node.
1. Prepare new bare-metal server node and create flavor contrail-controller-issu for ISSU node.The hardware requirements for ISSU node is the same as for the Contrail Controller Node.
2. Prepare parameters in the yaml file.
  tripleo-heat-templates/environments/contrail/contrail-issu-ffu.yaml: ContrailIssuSshKey - generate and put ssh keys (for ISSU there is SSH access required between ISSU and Contrail Controller nodes) Provide docker registry info: ContrailRegistryCertUrl, ContrailRegistry, ContrailRegistryInsecure, ContrailImageTag
3. Run deploy command with all parameters used for deployment and new environment file.
  '-e tripleo-heat-templates/environments/contrail/contrail-issu-ffu.yam
4. If you do not have internet access, after ISSU node installation, you must download required packages manually an a node with internet access, transfer packages on all the ISSU nodes and install them.
  To do so:
  1. Prepare required modules for docker-compose.
    
    Run the following commands on the a RHEL7 node which has internet access:
    yum install -y --enablerepo=rhel-server-rhscl-7-rpms python27-python-pip source scl_source enable python27 mkdir pip-pkg docker-compose-pkg pip download pip -d ./pip-pkg pip download pip -d ./docker-compose-pkg tar cvfz docker-compose.tar.gz docker-compose-pkg pip-pkg
  2. Upload the archive to all the ISSU nodes.
  3. Install packages on all the ISSU nodes.
    source scl_source enable python27 tar xvfz docker-compose.tar.gz pushd pip-pkg pip install * -f ./ --no-index popd pushd docker-compose-pkg pip install * -f ./ --no-index popd
Run In-Service Software Upgrade (ISSU).
1. Make SSH connection to ISSU node.
  
  Note:
  If you have 3 ISSU nodes deployed, you must perform SSH operations and run scripts on the same node for the entire procedure.
2. Deploy ISSU node.
  cd /etc/contrail/issu ./issu_node_deploy.sh
3. Check status of Contrail Networking service.
  sudo contrail-status
  
  The status must be active.
4. Pair ISSU node with the old cluster.
  ./issu_node_pair.sh
5. Check status of Contrail service on ISSU node.
  sudo contrail-status
  
  Note:
  All services must be active except config_devicemgr, config_schema and config_svcmonitor.
6. Run ISSU sync container.
  ./issu_node_sync.sh
7. Check ISSU container logs.
  sudo docker logs issu-run-sync Config Sync initiated... Config Sync done... Started runtime sync... Start Compute upgrade…
  sudo docker exec issu-run-sync cat /var/log/contrail/issu_contrail_run_sync.log 2019-02-21 17:03:56,769 SYS_DEBUG Control on node 192.168.206.115 has CID 427885c366a5 2019-02-21 17:03:56,875 SYS_INFO Signal sent to process. exit_code = 0, stdout = "[u'427885c366a5\n']", stderr="[]" 2019-02-21 17:03:56,878 SYS_INFO Start Compute upgrade..
Upgrade vRouter on Compute nodes.
Perform these steps on all the Compute Nodes.
1. Select the Compute node for upgrade and migrate workload from it.
2. Make SSH connection to Compute node.
3. Deploy new vRouter
  cd /etc/contrail/issu/ ./issu_compute_deploy.sh
4. Verify the network-functions-vrouter-ffu-env-pre file.
  cat /etc/sysconfig/network-scripts/network-functions-vrouter-ffu-env-pre TYPE=kernel BIND_INT=ens3 CONTRAIL_VROUTER_AGENT_CONTAINER_NAME=contrail_vrouter_agent
  You required this file because os-net-config is outdated in Newton and doesn’t provide the required variables for Contrail Networking Release 5.x or Release 1907 and later.
  
  For kernel mode and DPDK, the file is created automatically by the script mentioned in the step 5.d . Verify the file is created as per your deployment.
  DRIVER=uio_pci_generic CPU_LIST=0x1f BOND_MODE=4 BOND_POLICY=layer2+3 VLAN_ID=101
5. Reboot the node.
  sudo reboot
6. Make SSH connection to the compute node and verify node status.
  modinfo vrouter (for kernel mode) sudo contrail-status
