How do I achieve zero-downtime deployments for Prometheus?

To achieve zero-downtime deployments for Prometheus, you can utilize a combination of techniques including service discovery, rolling updates, and canary deployments. This approach ensures that monitoring continues without interruption even as you update components in your architecture.

Here’s an example of how you might configure Prometheus for zero-downtime deployments using service discovery:

# prometheus.yml global: scrape_interval: 15s scrape_configs: - job_name: 'my_service' service_discovery_configs: - kubernetes_sd_configs: - role: endpoints relabel_configs: - source_labels: [__meta_kubernetes_service_name] action: keep regex: my-service - source_labels: [__meta_kubernetes_namespace] action: keep regex: default
