Create CSAR with Helm chart as an artifact

We need to attach a tgz file to The CSAR is a heat template package . The basic with Helm chart in it. Basic package consists of an environment file, base_dummy.yaml file (for the sake of example) and 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 VNF project dictates the naming convention ; which must be followed while making the zip of all these filestgz.

NOTE: The Naming convention is for the helm chart zip tgz file.

Naming convention follows the format:

...

Cloudtech is a fixed pattern and should not be changed if not necessary
Technology: k8s, azure, aws, ….
Subtype: charts, day0, configtemplate, ...
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.

Listed below is an example of the contents inside a heat template package

vfw_k8s_demo.zip file is a zip of the 4 other files( manifest.json, base_dummy.env, base_dummy.yaml, vfw_cloudtech_k8s_juscharts.chartstgz) gets on boarded onto SDC.

$ vfw-k8s/package$ ls
MANIFEST.json base_dummy.env base_dummy.yaml vfw_cloudtech_k8s_charts.tgz vfw_k8s_demo.zip

NOTE:

...

MANIFEST.json

Key thing is note the addition of cloud artifact

REGISTER KUD CLOUD REGION with K8s-Plugin

API to support Reachability for Kubernetes Cloud

The command to POST Connectivity Info

{
   "cloud-region" : "<name>",   // Must be unique across
   "cloud-owner" : "<owner>",
   "other-connectivity-list" : {
          }

...

curl -i -F "metadata=<post.json;type=application/json" -F file=@

Register KUD Cloud region with AAI

With k8s cloud region, we need to add a tenant to the k8s cloud region. The 'easy' way is to have the ESR information (in step 1 of cloud registration) point to a real OpenStack tenant (e.g. the OOF tenant in the lab where we tested).

...

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.

                             ]

                   }
               ]
           }
    ]
}
}

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.

...

Sample Definition found here

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 ../

...

{
   "rb-name": "test-rbdef",
   "rb-version": "v1",
   "profile-name": "p1",
   "release-name": "r1", //If release-name is not provided, profile-name will be used
   "namespace": "testnamespace1",
   "kubernetes-version": "1.12.3"
}

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/v1/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/v1/profile/p1/content

Command to GET Profiles

# Get all Profiles
curl -i http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/rb/definition/test-rbdef/v1/profile

# Get one Profile
curl -i http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/rb/definition/test-rbdef/v1/profile/p1

Command to DELETE Profile

curl -i -X DELETE http://MSB_NODE_IP:30280/api/multicloud-k8s/v1/v1/rb/definition/test-rbdef/v1/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:

...

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

...

{
"id": "ZKMTSaxv",
"rb-name": "mongo",
"rb-version": "v1",
"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.
