Kubernetes integration for Sentry Streams

Sentry Streams K8s

Kubernetes integration for Sentry Streams.

Sentry Streams contains the streaming platform. That is everything that runs the streaming applications. Sentry Streams is agnostic to the way the application is deployed in production or in any environment.

This package instead provides the automation and the infrastructure to deploy Sentry Streams in a Kubernetes environment.

At the moment it targets Sentry production environment that is based on sentry-kube, though in the future we expect to have something more Sentry agnostic like Helm charts and a Kubernetes operator.

The Consumer Macro

The main component is the Consumer macro. This is a sentry-kube external macro that can be used inside the sentry-kube jinja template in the ops repo. This takes the basic deployment infrastructure (application specific) and fills it with containers and other resources to run the streaming platform.

The system to render a deployment would work this way:

graph LR
    subgraph sentry_streams_k8s
        consumer_macro[Consumer Macro]
        consumer_deployment[Consumer Deployment]
        config_map[Config Map]

        consumer_macro -- renders --> consumer_deployment
        consumer_macro -- renders --> config_map
    end

    subgraph ops_repo
        manifest[Manifest]
        deployment_template[Basic Deployment Template]
    end

    manifest -- imports --> deployment_template
    manifest -- imports --> consumer_macro

• The Consumer Macro renders all the Kubernetes resources to run the streaming platform.
• The application manifest is responsible to create all the resources needed to run the application (like service accounts or additional config maps)
• The basic structure of the deployment template is application specific, it contains settings like labeling scheme and nodepool selectors. We expect these to be provided to the macro by the application in the form of the deployment template.
