xmidt cloud components are deployed using a helm chart. Helm charts enables us to describe dependencies to 3rd party services like Consul or Prometheus. Make sure helm >= v3.0.0-beta.3 is installed on your system. helm-quickstart

If you need to make customisation (e.g. because of unique characteristics of your k8s instance):

ship is recommended

Getting Started

Use helm to render the chart to rendered.yaml:

helm template xmidt-cloud ./deploy/kubernetes/helm/xmidt-cloud/ > rendered.yaml

Now you can deploy the rendered chart to your k8s cluster:

kubectl apply -f rendered.yaml

Check if all pods are running (scytale might need a couple of restarts as it depends on consul):

kubectl get all
--
pod/caduceus-0                  1/1       Running   0          5d
pod/petasos-0                   1/1       Running   0          5d
pod/prometheus-0                1/1       Running   0          5d
pod/rdkb-simulator-0            1/1       Running   0          5d
pod/scytale-0                   1/1       Running   4          5d
pod/talaria-0                   1/1       Running   0          5d
pod/tr1d1um-0                   1/1       Running   0          5d
pod/xmidt-cloud-consul-0        1/1       Running   0          5d
pod/xmidt-cloud-consul-1        1/1       Running   0          5d
pod/xmidt-cloud-consul-2        1/1       Running   0          5d

To get the ports for tr1d1um and petasos use:

kubectl get all | grep 'service/tr1d1um-nodeport\|service/petasos-nodeport'
--
service/petasos-nodeport NodePort 10.247.241.180 <none>  6400:32659/TCP                                                                     3m
service/tr1d1um-nodeport NodePort 10.247.63.209  <none>  6100:31425/TCP

It means you can access tr1d1um on port 31425 and petasos on port 32659 on each node of your cluster.

Delete

You can delete your deployment with:

kubectl delete -f rendered.yaml

Updating this chart

If you make changes to a chart in a child reposiroties like talaria, etc. you can use the Makefile in helm to update this chart to the newest version.

cd helm
make update-latest

It will download all child charts and package them into xmidt-cloud/charts

FAQ

Consul pods are not running Consul depends on a PerstentVolumeClaim, make sure your k8s instance supports this.
You may also have to add annotations to the PerstentVolumeClaim section. If this is the case use ship to customize the xmidt helm chart.
