Helm Installation

Slice Analysis MS can be deployed using helm charts as kubernetes applications.

Deployment Pre-requisites

  • DCAE and DMaaP pods should be up and running.

  • PM mapper service should be running.

  • Config DB service, CPS and AAI should be running.

  • The environment should have helm and kubernetes installed.

  • Check whether all the charts mentioned in the requirements.yaml file are present in the charts/ folder. If not present, package the respective chart and put it in the charts/ folder.

    For example:
    helm package <dcaegen2-services-common>

Deployment steps

  1. Go to the directory where dcae-slice-analysis-ms chart is present and Execute the below command.
    helm install <slice_analysis_ms> <dcae-slice-analysis-ms> --namespace onap --set global.masterPassword=guilin2021
  2. We can check the logs of the slice-analysis-ms container by using the below command
    kubectl logs -f -n onap <dev-dcae-slice-analysis-ms-9fd8495f7-zmnlw> -c <dcae-slice-analysis-ms>
  3. To un-deploy
