The multicloud-k8s plugin provides APIs to upload self-contained HELM Charts that can be customized via the profile API and later installed in a particular cloud region. When the installation is complete (all the pods are either in running or completed state) vFW Helm Chart link: -------------------- https://github.com/onap/multicloud-k8s/tree/master/kud/demo/firewall EdgeXFoundry Helm Chart link: ----------------------------- https://github.com/onap/multicloud-k8s/tree/master/kud/tests/vnfs/edgex/helm/edgex **Create CSAR with Helm chart as an artifact** ---------------------------------------------- The CSAR is a heat template package with Helm chart in it. The basic package consists of an **environment file**, **base_dummy.yaml file** (example), **MANIFEST.json** and the **tar.gz** file (of Helm chart). We need to zip all of these files before onboarding. One thing to pay much attention to is the naming convention which must be followed while making the tgz. **NOTE: The Naming convention is for the helm chart tgz file.** **Naming convention follows the format:** \_\ ***cloudtech***\ \_\_.extension 1. *Cloudtech:* is a fixed pattern and should not be changed if not necessary 2. *Technology:* k8s, azure, aws 3. *Subtype*: charts, day0, config template 4. *Extension*: zip, tgz, csar NOTE: The .tgz file must be a tgz created from the top level helm chart folder. I.e. a folder that contains a Chart.yaml file in it. For vFW use case the content of tgz file must be following :: $ helm package firewall $ tar -tf firewall-0.1.0.tgz firewall/.helmignore firewall/Chart.yaml firewall/templates/onap-private-net.yaml firewall/templates/_helpers.tpl firewall/templates/protected-private-net.yaml firewall/templates/deployment.yaml firewall/templates/unprotected-private-net.yaml firewall/values.yaml firewall/charts/sink/.helmignore firewall/charts/sink/Chart.yaml firewall/charts/sink/templates/configmap.yaml firewall/charts/sink/templates/_helpers.tpl firewall/charts/sink/templates/service.yaml firewall/charts/sink/templates/deployment.yaml firewall/charts/sink/values.yaml firewall/charts/packetgen/.helmignore firewall/charts/packetgen/Chart.yaml firewall/charts/packetgen/templates/_helpers.tpl firewall/charts/packetgen/templates/deployment.yaml firewall/charts/packetgen/values.yaml Listed below is an example of the contents inside a heat template package :: $ vfw-k8s/package$ ls MANIFEST.json base_dummy.env base_dummy.yaml vfw_cloudtech_k8s_charts.tgz vfw_k8s_demo.zip **MANIFEST.json** ~~~~~~~~~~~~~~~~~ Key thing is note the addition of cloud artifact :: type: "CLOUD_TECHNOLOGY_SPECIFIC_ARTIFACTS" { "name": "", "description": "", "data": [ { "file": "base_dummy.yaml", "type": "HEAT", "isBase": "true", "data": [ { "file": "base_dummy.env", "type": "HEAT_ENV" } ] }, { "file": "vfw_cloudtech_k8s_charts.tgz", "type": "CLOUD_TECHNOLOGY_SPECIFIC_ARTIFACTS" } ] } **base\_dummy.yaml** ~~~~~~~~~~~~~~~~~~~~~ Designed to be minimal HEAT template :: ##==================LICENSE_START======================================== ## ## Copyright (C) 2019 Intel Corporation ## SPDX-License-Identifier: Apache-2.0 ## ##==================LICENSE_END=========================================== heat_template_version: 2016-10-14 description: Heat template to deploy dummy VNF parameters: dummy_name_0: type: string label: name of vm description: Dummy name vnf_id: type: string label: id of vnommand to read (GET) Definition description: Provided by ONAP vnf_name: type: string label: name of vnf description: Provided by ONAP vf_module_id: type: string label: vnf module id description: Provided by ONAP dummy_image_name: type: string label: Image name or ID description: Dummy image name dummy_flavor_name: type: string label: flavor description: Dummy flavor resources: dummy_0: type: OS::Nova::Server properties: name: { get_param: dummy_name_0 } image: { get_param: dummy_image_name } flavor: { get_param: dummy_flavor_name } metadata: { vnf_name: { get_param: vnf_name }, vnf_id: { get_param: vnf_id }, vf_module_id: { get_param: vf_module_id }} **base\_dummy.env** :: parameters: vnf_id: PROVIDED_BY_ONAP vnf_name: PROVIDED_BY_ONAP vf_module_id: PROVIDED_BY_ONAP dummy_name_0: dummy_1_0 dummy_image_name: dummy dummy_flavor_name: dummy.default **Onboard the CSAR** -------------------- For onboarding instructions please refer to steps 4-9 from the document `here `__. **Steps for installing KUD Cloud** ---------------------------------- Follow the link to install KUD Kubernetes Deployment. KUD contains all the packages required for running vfw use case. Kubernetes Baremetal deployment instructions here_ .. _here: https://wiki.onap.org/display/DW/Kubernetes+Baremetal+deployment+setup+instructions/ **REGISTER KUD CLOUD REGION with K8s-Plugin** --------------------------------------------- API to support Reachability for Kubernetes Cloud **The command to POST connectivity info** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ :: { "cloud-region" : "", // Must be unique across "cloud-owner" : "", "other-connectivity-list" : { } This is a multipart upload and here is how you do the POST for this. #Using a json file (eg: post.json) containing content as above :: curl -i -F "metadata=`__, the service-subscription can be added to that object. NOTE: use same name cloud-region and cloud-owner name An example is shown below for K8s cloud but following the steps 1,2,3 from `here `__. The sample input below is for k8s cloud type. **Step 1 - Cloud Registration/ Create a cloud region to represent the instance.** Note: highlighted part of the body refers to an existing OpenStack tenant (OOF in this case). Has nothing to do with the K8s cloud region we are adding. :: PUT https://{{AAI1_PUB_IP}}:{{AAI1_PUB_PORT}}/aai/v13/cloud-infrastructure/cloud-regions/cloud-region/k8scloudowner4/k8sregionfour { "cloud-owner": "k8scloudowner4", "cloud-region-id": "k8sregionfour", "cloud-type": "k8s", "owner-defined-type": "t1", "cloud-region-version": "1.0", "complex-name": "clli1", "cloud-zone": "CloudZone", "sriov-automation": false, "cloud-extra-info":"{\"openstack-region-id\":\"k8sregionthree\"}", "esr-system-info-list": { "esr-system-info": [ { "esr-system-info-id": "55f97d59-6cc3-49df-8e69-926565f00066", "service-url": "http://10.12.25.2:5000/v3", "user-name": "demo", "password": "onapdemo", "system-type": "VIM", "ssl-insecure": true, "cloud-domain": "Default", "default-tenant": "OOF", "tenant-id": "6bbd2981b210461dbc8fe846df1a7808", "system-status": "active" } ] } } **Step 2 add a complex to the cloud** Note: just adding one that exists already :: PUT https://{{AAI1_PUB_IP}}:{{AAI1_PUB_PORT}}/aai/v13/cloud-infrastructure/cloud-regions/cloud-region/k8scloudowner4/k8sregionfour/relationship-list/relationship { "related-to": "complex", "related-link": "/aai/v13/cloud-infrastructure/complexes/complex/clli1", "relationship-data": [ { "relationship-key": "complex.physical-location-id", "relationship-value": "clli1" } ] } **Step 3 - Trigger the Multicloud plugin registration process** :: POST http://{{MSB_IP}}:{{MSB_PORT}}/api/multicloud-titaniumcloud/v1/k8scloudowner4/k8sregionfour/registry This registers the K8S cloud with Multicloud it also reaches out and adds tenant information to the cloud (see example below you'll see all kinds of flavor, image information that is associated with the OOF tenant). If we had not done it this way, then wed have to go in to AAI at this point and manually add a tenant to the cloud region. The first time I tried this (k8s region one), I just made up some random tenant id and put it in.) The tenant is there so you can add the service-subscription to it: **Making a Service Type:** :: PUT https://{{AAI1_PUB_IP}}:{{AAI1_PUB_PORT}}/aai/v13/service-design-and-creation/services/service/vfw-k8s { "service-description": "vfw-k8s", "service-id": "vfw-k8s" } Add subscription to service type to the customer (Demonstration in this case which was already created by running the robot demo scripts) :: PUT https://{{AAI1_PUB_IP}}:{{AAI1_PUB_PORT}}/aai/v16/business/customers/customer/Demonstration/service-subscriptions/service-subscription/vfw-k8s { "service-type": "vfw-k8s" } Add Service-Subscription to the tenant (resource-version changes based on actual value at the time): :: PUT https://{{AAI1_PUB_IP}}:{{AAI1_PUB_PORT}}/aai/v16/cloud-infrastructure/cloud-regions/cloud-region/k8scloudowner4/k8sregionfour/tenants/tenant/6bbd2981b210461dbc8fe846df1a7808?resource-version=1559345527327 { "tenant-id": "6bbd2981b210461dbc8fe846df1a7808", "tenant-name": "OOF", "resource-version": "1559345527327", "relationship-list": { "relationship": [ { "related-to": "service-subscription", "relationship-label": "org.onap.relationships.inventory.Uses", "related-link": "/aai/v13/business/customers/customer/Demonstration/service-subscriptions/service-subscription/vfw-k8s", "relationship-data": [ { "relationship-key": "customer.global-customer-id", "relationship-value": "Demonstration" }, { "relationship-key": "service-subscription.service-type", "relationship-value": "vfw-k8s" } ] } ] } } **Distribute the CSAR** ----------------------- Onboard a service it gets stored in SDC final action is distributed. SO and other services are notified sdc listener in the multicloud sidecar. When distribution happens it takes tar.gz file and uploads to k8s plugin. **Create Profile Manually** --------------------------- K8s-plugin artifacts start in the form of Definitions. These are nothing but Helm Charts wrapped with some metadata about the chart itself. Once the Definitions are created, we are ready to create some profiles so that we can customize that definition and instantiate it in Kubernetes. NOTE: Refer this link_ for complete API lists and documentation: .. _link : https://wiki.onap.org/display/DW/MultiCloud+K8s-Plugin-service+API A profile consists of the following: **manifest.yaml** - Contains the details for the profile and everything contained within A **HELM** values override yaml file. - It can have any name as long as it matches the corresponding entry in the **manifest.yaml** Any number of files organized in a folder structure - All these files should have a corresponding entry in **manifest.yaml** file **Creating a Profile Artifact** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ :: > cd multicloud-k8s/kud/tests/vnfs/testrb/helm/profile > find . manifest.yaml override_values.yaml testfol testfol/subdir testfol/subdir/deployment.yaml #Create profile tar.gz > cd profile > tar -cf profile.tar * > gzip profile.tar > mv profile.tar.gz ../ The manifest file contains the following :: --- version: v1 type: values: "values_override.yaml" configresource: - filepath: testfol/subdir/deployment.yaml chartpath: vault-consul-dev/templates/deployment.yaml Note: values: "values\_override.yaml" can **be** empty **file** **if** you are creating **a** dummy **profile** Note: A dummy profile does not need any customization. The following is optional in the manifest file. :: configresource: - filepath: testfol/subdir/deployment.yaml chartpath: vault-consul-dev/templates/deployment.yaml We need to read the name of the Definition which was created while distribution of the service from SDC. **Command to read the Definition name and its version** On the ONAP K8s Rancher host execute following statement :: kubectl logs -n onap `kubectl get pods -o go-template --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}' | grep multicloud-k8s | head -1` -c multicloud-k8s From the output read the name of the definition which is "rb-name" and "rb-version" respectively :: 127.0.0.1 - - [15/Jul/2019:07:56:21 +0000] "POST /v1/rb/definition/test-rbdef/1/content HTTP/1.1" **Command to read (GET) Definition** With this information, we are ready to upload the profile with the following JSON data :: { "rb-name": "test-rbdef", "rb-version": "1", "profile-name": "p1", "release-name": "r1", //If release-name is not provided, profile-name will be used "namespace": "testnamespace1", "kubernetes-version": "1.13.5" } **Command to create (POST) Profile** ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: curl -i -d @create_rbprofile.json -X POST http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/rb/definition/test-rbdef/1/profile **Command to UPLOAD artifact for Profile** :: curl -i --data-binary @profile.tar.gz -X POST http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/rb/definition/test-rbdef/1/profile/p1/content **Command to GET Profiles** :: curl -i http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/rb/definition/test-rbdef/1/profile # Get one Profile curl -i http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/rb/definition/test-rbdef/1/profile/p1 **Command to DELETE Profile** :: curl -i -X DELETE http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/rb/definition/test-rbdef/1/profile/p1 **Instantiation** ----------------- Instantiation is done by SO. SO then talks to Multi Cloud-broker via MSB and that in turn looks up the cloud region in AAI to find the endpoint. If k8sregion one is registered with AAI and SO makes a call with that, then the broker will know that it needs to talk to k8s-plugin based on the type of the registration. **Instantiate the created Profile via the following REST API** :: Using the following JSON: { "cloud-region": "kud", "profile-name": "p1", "rb-name":"test-rbdef", "rb-version":"1", "labels": { } } **NOTE**: Make sure that the namespace is already created before instantiation. Instantiate the profile with the ID provided above **Command to Instantiate a Profile** :: curl -d @create_rbinstance.json http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/instance The command returns the following JSON :: { "id": "ZKMTSaxv", "rb-name": "mongo", "rb-version": "1", "profile-name": "profile1", "cloud-region": "kud", "namespace": "testns", "resources": [ { "GVK": { "Group": "", "Version": "v1", "Kind": "Service" }, "Name": "mongo" }, { "GVK": { "Group": "", "Version": "v1", "Kind": "Service" }, "Name": "mongo-read" }, { "GVK": { "Group": "apps", "Version": "v1beta1", "Kind": "StatefulSet" }, "Name": "profile1-mongo" } ] } **Delete Instantiated Kubernetes resources** The **id** field from the returned JSON can be used to **DELETE** the resources created in the previous step. This executes a Delete operation using the Kubernetes API. :: curl -X DELETE http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/instance/ZKMTSaxv **GET Instantiated Kubernetes resources** The **id field** from the returned JSON can be used to **GET** the resources created in the previous step. This executes a get operation using the Kubernetes API. :: curl -X GET http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/instance/ZKMTSaxv `*\ https://github.com/onap/oom/blob/master/kubernetes/multicloud/resources/config/provider-plugin.json `__ **Create User parameters** We need to create parameters that ultimately get translated as: :: "user_directives": { "attributes": [ { "attribute_name": "definition-name", "attribute_value": "edgex" }, { "attribute_name": "definition-version", "attribute_value": "v1" }, { "attribute_name": "profile-name", "attribute_value": "profile1" } ] }
