INF O2 Service User Guide

This guide will introduce the process that make INF O2 interface work with SMO.

  • Assume you have an O2 service with INF platform environment

    export OAM_IP=<INF_OAM_IP>
  • Discover INF platform inventory

    • INF platform auto discovery

      After you installed the INF O2 service, it will automatically discover the INF through the parameters that you give from the “o2service-override.yaml

      Below command can get the INF platform information as O-Cloud

      curl -X 'GET' \
        "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/" \
        -H 'accept: application/json'
    • Resource pool

      One INF platform have one resource pool, all the resources that belong to this INF platform will be organized into this resource pool

      Get the resource pool information through this interface

      curl -X 'GET' \
        "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/resourcePools" \
        -H 'accept: application/json'
      # export resource pool id
      export resourcePoolId=`curl -X 'GET'   "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/resourcePools"   -H 'accept: application/json' -H 'X-Fields: resourcePoolId' 2>/dev/null | jq .[].resourcePoolId | xargs echo`
      echo ${resourcePoolId} # check the exported resource pool id
    • Resource type

      Resource type defined what type is the specified resource, like a physical machine, memory, or CPU

      Show all resource type

      curl -X 'GET' \
        "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/resourceTypes" \
        -H 'accept: application/json'
    • Resource

      Get the list of all resources, the value of resourcePoolId from the result of resource pool interface

      curl -X 'GET' \
        "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/resourcePools/${resourcePoolId}/resources" \
        -H 'accept: application/json'

      Get detail of one resource, need to export one specific resource id that wants to check

      curl -X 'GET' \
        "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/resourcePools/${resourcePoolId}/resources/${resourceId}" \
        -H 'accept: application/json'
    • Deployment manager services endpoint

      The Deployment Manager Service (DMS) that related to this IMS information you can use below API to check

      curl -X 'GET' \
        "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/deploymentManagers" \
        -H 'accept: application/json'
  • Provisioning INF platform with SMO endpoint configuration

    Assume you have an SMO, then configure INF platform with SMO endpoint address. This provisioning of INF O2 service will make a request from INF O2 service to SMO, that make SMO know the O2 service is working.

    It needs SMO to have an API like “http(s)://SMO_HOST:SMO_PORT/registration”, which can accept JSON format data.

    curl -X 'POST' \
      'http://'${OAM_IP}':30205/provision/v1/smo-endpoint' \
      -H 'accept: application/json' \
      -H 'Content-Type: application/json' \
      -d '{
      "endpoint": "http://<SMO_HOST>:<SMO_PORT>/registration"
  • Subscribe to the INF platform resource change notification

    Assume you have an SMO, and the SMO have an API can be receive callback request

    • Create subscription in the INF O2 IMS

      curl -X 'POST' \
        "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/subscriptions" \
        -H 'accept: application/json' \
        -H 'Content-Type: application/json' \
        -d '{
        "callback": "http://SMO/address/to/callback",
        "consumerSubscriptionId": "<ConsumerIdHelpSmoToIdentify>",
        "filter": "<ResourceTypeNameSplitByComma,EmptyToGetAll>"
    • Handle resource change notification

      When the SMO callback API get the notification that the resource of INF platform changing, use the URL to get the latest resource information to update its database

  • Orchestrate CNF in helm chart

    On this sample, we prepare a firewall chart to test the orchestration.

    We need to do some preparation to make the helm repo work and include our firewall chart inside of the repository.

    Get the DMS Id in the INF O2 service, and set it into bash environment

    curl --location --request GET "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/deploymentManagers"
    export dmsId=`curl --location --request GET "http://${OAM_IP}:30205/o2ims_infrastructureInventory/v1/deploymentManagers" 2>/dev/null | jq .[].deploymentManagerId | xargs echo`
    echo ${dmsId} # check the exported DMS id

    Using helm to deploy a chartmuseum to the INF platform

    helm repo add chartmuseum
    helm repo update
    helm pull chartmuseum/chartmuseum # download chartmuseum-3.4.0.tgz to local
    tar zxvf chartmuseum-3.4.0.tgz
    cat <<EOF>chartmuseum-override.yaml
        DISABLE_API: false
      type: NodePort
      nodePort: 30330
    helm install chartmuseumrepo chartmuseum/chartmuseum -f chartmuseum-override.yaml
    kubectl get pods
    Kubectl get services

    Update the helm repo and add the chartmusem into the repository

    helm repo add o2imsrepo http://${NODE_IP}:30330
    helm repo update

    Download the firewall chart and push it into the repository

    git clone
    tar -zcvf firewall-host-netdevice-1.0.0.tgz firewall-host-netdevice/
    helm plugin install
    helm cm-push firewall-host-netdevice-1.0.0.tgz o2imsrepo
    helm repo update
    helm search repo firewall

    Setup host net device over INF node

    ssh sysadmin@<INF OAM IP>
    sudo ip link add name veth11 type veth peer name veth12
    sudo ip link add name veth21 type veth peer name veth22
    sudo ip link |grep veth
    • Create NfDeploymentDescriptor on the INF O2 DMS

      curl --location --request POST "http://${OAM_IP}:30205/o2dms/v1/${dmsId}/O2dms_DeploymentLifecycle/NfDeploymentDescriptor" \
      --header 'Content-Type: application/json' \
      --data-raw '{
        "name": "cfwdesc1",
        "description": "demo nf deployment descriptor",
        "artifactRepoUrl": "http://'${NODE_IP}':30330",
        "artifactName": "firewall-host-netdevice",
        "{\n  \"image\": {\n    \"repository\": \"ubuntu\",\n    \"tag\": 18.04,\n    \"pullPolicy\": \"IfNotPresent\"\n  },\n  \"resources\": {\n    \"cpu\": 2,\n    \"memory\": \"2Gi\",\n    \"hugepage\": \"0Mi\",\n    \"unprotectedNetPortVpg\": \"veth11\",\n    \"unprotectedNetPortVfw\": \"veth12\",\n    \"unprotectedNetCidr\": \"\",\n    \"unprotectedNetGwIp\": \"\",\n    \"protectedNetPortVfw\": \"veth21\",\n    \"protectedNetPortVsn\": \"veth22\",\n    \"protectedNetCidr\": \"\",\n    \"protectedNetGwIp\": \"\",\n    \"vfwPrivateIp0\": \"\",\n    \"vfwPrivateIp1\": \"\",\n    \"vpgPrivateIp0\": \"\",\n    \"vsnPrivateIp0\": \"\"\n  }\n}",
        "outputParams": "{\"output1\": 100}"
      curl --location --request GET "http://${OAM_IP}:30205/o2dms/v1/${dmsId}/O2dms_DeploymentLifecycle/NfDeploymentDescriptor"
      export descId=` curl -X 'GET'   "http://${OAM_IP}:30205/o2dms/v1/${dmsId}/O2dms_DeploymentLifecycle/NfDeploymentDescriptor"   -H 'accept: application/json'   -H 'X-Fields: id' 2>/dev/null | jq .[].id | xargs echo`
      echo ${descId} # check the exported descriptor id
    • Create NfDeployment on the INF O2 DMS

      When you have an descriptor of deployment, you can create a NfDeployment, it will trigger an event inside of the IMS/DMS, and use the K8S API to create a real pod of the firewall sample

      curl --location --request POST "http://${OAM_IP}:30205/o2dms/v1/${dmsId}/O2dms_DeploymentLifecycle/NfDeployment" \
      --header 'Content-Type: application/json' \
      --data-raw '{
        "name": "cfw100",
        "description": "demo nf deployment",
        "descriptorId": "'${descId}'",
        "parentDeploymentId": ""
      curl --location --request GET "http://${OAM_IP}:30205/o2dms/v1/${dmsId}/O2dms_DeploymentLifecycle/NfDeployment"
    • Check pods of the firewall sample

      kubectl get pods
    • Delete the deployment we just created

      export NfDeploymentId=`curl --location --request GET "http://${OAM_IP}:30205/o2dms/v1/${dmsId}/O2dms_DeploymentLifecycle/NfDeployment" 2>/dev/null | jq .[].id | xargs echo`
      echo ${NfDeploymentId} # Check the exported deployment id
      curl --location --request DELETE "http://${OAM_IP}:30205/o2dms/v1/${dmsId}/O2dms_DeploymentLifecycle/NfDeployment/${NfDeploymentId}"
