Helm Charts

Service Addition Guide

In order to add a new service to the helm chart follow the steps:

• Copy one of the services folders and change it's name. cp api-gateway <new service name>

• in <new service name>\Chart.yaml

  • Change name to be the name of the service.
  • Change version to the version of the service you deploy.

• in <new service name>\values.yaml

  • Change tag, nameOverride, fullnameOverride with the new correct values.
  • Change port to be the external(cluster-scoped) binded port and the targetPort to be the internal binded port (preferd to be identical, if the service is exposed prefer port 80, otherwise use 8080).
  • If the service is not exposed to the internet(outside of the cluster) change:

    ingress:
      enabled: true
    

    To be:

    ingress:
      enabled: false
    

    and remove <new service name>\templates\ingress.yaml by running the following command: rm <new service name>\templates\ingress.yaml
  • If it is exposed to the internet(outside of the cluster) make sure that ingress is enabled as seen above.

• In helm-chart\requirements.yaml

  • Add:

    - name: <new service name>
      version: <new service version>
      repository: file://../<new service name>
    

Make sure everything is Indented correctly!

Deploy To Kubernetes

After editing the chart, run the following commands:

• To Initialize Helm run: helm init --client-only

• ./helm-dep-up-umbrella.sh helm-chart/ in the main repo directory.

• If you are updating the environment or want to deploy your environment with the same deployment name you need to delete your deployment first.

  use:

  helm del --purge <deployment name>
  

• helm install <chart to deploy> --name <deployment name> --namespace <wanted namespace> --set global.ingress.hosts[0]=<wanted namespace>.northeurope.cloudapp.azure.com
  

  In order to deploy all of the services, use helm-chart as the chart to deploy.

• In order to see your deployment status use:

  helm status <deployment name>
  

Update ConfigMap:

• Delete ConfigMap:

  kubectl delete configmap kd.config --namespace <wanted namespace>
  

• Recreate your ConfigMap:

  kubectl create configmap --from-env-file=<location of the env file> kd.config --namespace <wanted namespace>
  

• Restart your deployment:

  helm upgrade <deployment name> helm-chart --recreate-pods --namespace <wanted namespace>
