For DCAE services deployed via blueprint, below steps can be followed to trial out new blueprint/inputs

1) Using ONAP key, you can login into rancher vm on required tenant DCAE/integration-SB04/Integration-OOM-Daily/Integration-OOM-Staging-Daily

For e.g – for SB04 rancher ip 
>>ssh -i ~/onap_dev  ubuntu@

    Note: Use DCAE tenant if your components is not targeted for current release. The onap_dev is common key used across all VM in WINlab.

2) Using kubectl find the pod for bootstrap and exec into it

>>kubectl exec -it -n onap dev-dcaegen2-dcae-bootstrap-776cf86d49-mxzq6 /bin/bash

3) The blueprint for Holmes rules/engine component are under /blueprints (this is basically pulled from nexus raw during container build) and corresponding input file is under /inputs (this gets mapped during deployment from what is specified under oom repo). Here you can basically modify the image tag or any other blueprint changes to trial/deploy.

4) Deploy (or undeploy) commands.

If the component is already deployed (run "cfy deployments list" to check), then uninstall first


Syntax - cfy uninstall <deployment to be uninstalled>
>>cfy uninstall holmes_rules

Remove the deployment (this is required if uninstall does not remove the deployment automatically)

Syntax - cfy deployments delete -f <deployment name>
>>cfy deployments delete -f holmes_rules

Delete older version of blueprint (run "cfy blueprints list" to get current list; this is required if uninstall does not remove the deployment automatically) 

Syntax - cfy blueprints delete <blueprint name>
>>cfy blueprints delete holmes_rules

Validate the new blueprint changes

Syntax - cfy blueprints validate <blueprint filename>
>> cfy blueprints validate k8s-holmes-rules.yaml

Upload the new blueprint

Syntax - cfy blueprints upload -b <blueprintname> <blueprint file path>
>>cfy blueprints upload -b holmes_rules /blueprints/k8s-holmes-rules.yaml

Create a new deployment with updated blueprint

Syntax - cfy deployments create -b <blueprint name> -i <input file path> <deployment name>
>>cfy deployments create -b holmes_rules -i /inputs/k8s-holmes_rules-inputs.yaml holmes_rules

Execute install workflow

Syntax - cfy executions start -d <deployment name> install
>>cfy executions start -d holmes_rules install 

Note: Examples are captured around  holmes_engine; replace holmes_engine and corresponding blueprint/input file name required.

5) Verify status/logs

>>root@onap-oom-rancher:~# kubectl get pods -n onap | grep holmes
dep-holmes-engine-mgmt-885d86d49-czh28                       0/1       Running   61         10h
dep-holmes-rule-mgmt-5ffd74f697-bb7xp                         0/1       Running   61         10h                                                                               

The component version used in deployment can be checked using below command.

>> kubectl describe pod -n onap dep-holmes-engine-mgmt-885d86d49-czh28 

Rolling upgrade of deployed components

DCAE platform for R3 supports rolling upgrade of individual component deployed via cloudify.

To upgrade a running pod, follow below syntax

cfy execution start -d <deployment name> <inputfile> execute_operation

<input file> - should be under following structure

operation: update_image


    image: <complete path of image:tag>


    - <list of node_id's in blueprint to be updated>

Example: cfy executions start -d ves -p k8s-ves-image.yaml execute_operation

Where k8s-ves-image.yaml is set as below

operation: update_image




    - "ves"

Example of rolling upgrade executions (logs for Data-file collector)


cfy executions start -d datafile-collector -p k8s-datafile-collector-image.yaml execute_operation
