第 5 章 缩减 director Operator 资源

在将数据库迁移到 control plane 之前，您必须缩减和删除 OpenStack director Operator (OSPdO)资源，才能使用 OpenShift (RHOSO)资源。

您必须执行以下操作：

  • 从现有 RHOSP 17.1 集群中转储所选数据。您可以使用此数据为 data plane 采用构建自定义资源。
  • 提取并保存数据后，删除 OSPdO control plane 和 Operator。

流程

  1. 下载 NIC 模板： 

        # Make temp directory if doesn't exist
    mkdir -p temp
    cd temp
    echo "Extract nic templates"
    oc get -n "${OSPDO_NAMESPACE}" cm tripleo-tarball -ojson | jq -r '.binaryData."tripleo-tarball.tar.gz"' | base64 -d | tar xzvf -
    # Revert back to original directory
    cd -
    Copy to Clipboard Toggle word wrap

  2. 获取用于访问数据平面节点的 SSH 密钥： 

        # Make temp directory if doesn't exist
    mkdir -p temp
    # Get the SSH key from the openstackclient (osp 17)
    # to be used later to create the SSH secret for dataplane adoption
    $OS_CLIENT cat /home/cloud-admin/.ssh/id_rsa > temp/ssh.private
    $OS_CLIENT cat /home/cloud-admin/.ssh/id_rsa.pub > temp/ssh.pub
    echo "SSH private and public keys saved in temp/ssh.private and temp/ssh.pub"
    Copy to Clipboard Toggle word wrap

  3. 从每个 Compute 节点角色 OpenStackBaremetalSet 获取 OVN 配置。稍后使用这个配置来构建 OpenStackDataPlaneNodeSet(s)。为每个 OpenStackBaremetalSet 重复此步骤： 

        # Make temp directory if doesn't exist
    mkdir -p temp
        #
        # Query the first node in OSBMS
        #
    IP=$(oc -n "${OSPDO_NAMESPACE}" get openstackbaremetalsets.osp-director.openstack.org <<OSBMS-NAME>> -ojson |           jq -r '.status.baremetalHosts| keys[] as $k | .[$k].ipaddresses["ctlplane"]'| awk -F'/' '{print $1}')
    # Get the OVN parameters
    oc -n "${OSPDO_NAMESPACE}" exec -c openstackclient openstackclient -- \
        ssh cloud-admin@${IP} sudo ovs-vsctl -f json --columns=external_ids list Open |
        jq -r '.data[0][0][1][]|join("=")' | sed -n -E 's/^(ovn.*)+=(.*)+/edpm_\1: \2/p' |
        grep -v -e ovn-remote -e encap-tos -e openflow -e ofctrl > temp/<<OSBMS-NAME>>.txt
    Copy to Clipboard Toggle word wrap 
        # Create temp directory if it does not exist
    mkdir -p temp
    for name in $(oc -n "${OSPDO_NAMESPACE}" get openstackbaremetalsets.osp-director.openstack.org | awk 'NR > 1 {print $1}'); do
      oc -n "${OSPDO_NAMESPACE}" get openstackbaremetalsets.osp-director.openstack.org $name -ojson |
          jq -r '.status.baremetalHosts| "nodes:", keys[] as $k | .[$k].ipaddresses as $a |
           "  \($k):",
           "    hostName: \($k)",
           "    ansible:",
           "      ansibleHost: \($a["ctlplane"] | sub("/\\d+"; ""))",
           "    networks:", ($a | to_entries[] | "    - name: \(.key) \n      fixedIP: \(.value | sub("/\\d+"; ""))\n      subnetName: subnet1")' > temp/${name}-nodes.txt
    done
    Copy to Clipboard Toggle word wrap

  4. 从所有 Compute 主机中删除冲突的存储库和软件包。定义必须停止的 OSPdO 和 RHOSP 17.1 Pacemaker 服务： 

    PacemakerResourcesToStop_dataplane=(
                "galera-bundle"
                "haproxy-bundle"
                "rabbitmq-bundle")

# Stop these PCM services after adopting control
# plane, but before starting deletion of OSPD0 (osp17) env
    echo "Stopping pacemaker OpenStack services"
    SSH_CMD=CONTROLLER_SSH
    if [ -n "${!SSH_CMD}" ]; then
        echo "Using controller 0 to run pacemaker commands "
        for resource in "${PacemakerResourcesToStop_dataplane[@]}"; do
            if ${!SSH_CMD} sudo pcs resource config "$resource" &>/dev/null; then
                echo "Stopping $resource"
                ${!SSH_CMD} sudo pcs resource disable "$resource"
            else
                echo "Service $resource not present"
            fi
        done
    fi
    Copy to Clipboard Toggle word wrap

  5. 将 RHOSO OpenStack Operator controller-manager 缩减为 0 个副本，并临时删除 OpenStackControlPlane OpenStackClient pod，以便您可以使用 OSPdO controller-manager 清理其一些资源。需要清理，以避免 OSPdO OpenStackClient 和 RHOSO OpenStackClient 之间的 pod 名称冲突。 

    $ oc patch csv -n openstack-operators openstack-operator.v1.0.5 --type json   -p="[{"op": "replace", "path": "/spec/install/spec/deployments/0/spec/replicas", "value": "0"}]"
$ oc delete openstackclients.client.openstack.org --all
    Copy to Clipboard Toggle word wrap
    • 将 CSV 版本替换为集群中部署的 CSV 版本。

  6. 删除 OSPdO OpenStackControlPlane 自定义资源(CR)： 

    $ oc delete openstackcontrolplanes.osp-director.openstack.org -n "${OSPDO_NAMESPACE}" --all
    Copy to Clipboard Toggle word wrap

  7. 删除 OSPdO OpenStackNetConfig CR，以删除关联的节点网络配置策略： 

    $ oc delete osnetconfig -n "${OSPDO_NAMESPACE}" --all
    Copy to Clipboard Toggle word wrap

  8. 标记包含 OSPdO 虚拟机(VM)的 RHOCP 节点： 

    $ oc label nodes <ospdo_vm_master_node> type=openstack
    Copy to Clipboard Toggle word wrap
    • 将 <ospdo_vm_master_node > 替换为包含 OSPdO 虚拟机的剩余 master 节点。

  9. 为第三个 RHOCP 节点创建节点网络配置策略。例如： 

    $ cat << EOF > /tmp/node3_nncp.yaml

EOF

$ oc apply -f /tmp/node3_nncp.yaml
    Copy to Clipboard Toggle word wrap

  10. 删除剩余的 OSPdO 资源。不要删除 OpenStackBaremetalSets 和 OpenStackProvisionServer 资源： 

    $ for i in $(oc get crd | grep osp-director | grep -v baremetalset | grep -v provisionserver | awk {'print $1'}); do echo Deleting $i...; oc delete $i -n "${OSPDO_NAMESPACE}" --all; done
    Copy to Clipboard Toggle word wrap

  11. 将 OSPdO 缩减为 0 个副本： 

    $ ospdo_csv_ver=$(oc get csv -n "${OSPDO_NAMESPACE}" -l operators.coreos.com/osp-director-operator.openstack -o json | jq -r '.items[0].metadata.name')
$ oc patch csv -n "${OSPDO_NAMESPACE}" $ospdo_csv_ver --type json   -p="[{"op": "replace", "path": "/spec/install/spec/deployments/0/spec/replicas", "value": "0"}]"
    Copy to Clipboard Toggle word wrap

  12. 从 OSPdO 中删除 webhook： 

    $ oc patch csv $ospdo_csv_ver -n "${OSPDO_NAMESPACE}" --type json -p="[{"op": "remove", "path": "/spec/webhookdefinitions"}]"
    Copy to Clipboard Toggle word wrap

  13. 从 OSPdO OpenStackBaremetalSet 资源中删除终结器： 

    $ oc patch openstackbaremetalsets.osp-director.openstack.org -n "${OSPDO_NAMESPACE}" compute --type json -p="[{"op": "remove", "path": "/metadata/finalizers"}]"
    Copy to Clipboard Toggle word wrap

  14. 删除 OpenStackBaremetalSet 和 OpenStackProvisionServer 资源： 

    $ oc delete openstackbaremetalsets.osp-director.openstack.org -n "${OSPDO_NAMESPACE}" --all
$ oc delete openstackprovisionservers.osp-director.openstack.org -n "${OSPDO_NAMESPACE}" --all
    Copy to Clipboard Toggle word wrap

  15. 注解每个 RHOSP Compute BareMetalHost 资源，以便 Metal3 不会启动节点： 

    $ compute_bmh_list=$(oc get bmh -n openshift-machine-api |grep compute|awk '{printf $1 " "}')
$ for bmh_compute in $compute_bmh_list;do oc annotate bmh -n openshift-machine-api $bmh_compute baremetalhost.metal3.io/detached="";\
     oc -n openshift-machine-api wait bmh/$bmh_compute --for=jsonpath='{.status.operationalStatus}'=detached --timeout=30s || {
         echo "ERROR: BMH did not enter detatched state"
         exit 1
       }
done
    Copy to Clipboard Toggle word wrap

  16. 在其操作状态被分离后删除 BareMetalHost 资源： 

        for bmh_compute in $compute_bmh_list;do \
       oc -n openshift-machine-api delete bmh $bmh_compute; \
    done
    Copy to Clipboard Toggle word wrap

  17. 删除 OSPdO Operator Lifecycle Manager 资源以删除 OSPdO： 

    $ oc delete subscription osp-director-operator -n "${OSPDO_NAMESPACE}"
$ oc delete operatorgroup osp-director-operator -n "${OSPDO_NAMESPACE}"
$ oc delete catalogsource osp-director-operator-index -n "${OSPDO_NAMESPACE}"
$ oc delete csv $ospdo_csv_ver -n "${OSPDO_NAMESPACE}"
    Copy to Clipboard Toggle word wrap

  18. 将 RHOSO OpenStack Operator controller-manager 扩展为 1 个副本，以便协调关联的 OpenStackControlPlane CR，并重新创建其 OpenStackClient pod： 

    $ oc patch csv -n "${OSPDO_NAMESPACE}"-operators openstack-operator.v0.0.1 --type json   -p="[{"op": "replace", "path": "/spec/install/spec/deployments/0/spec/replicas", "value": "1"}]"
