DCDR

OpenTelemetry-native APM — no-ZooKeeper, single-node ClickHouse profile per cluster.

Quick facts

Profile
No-ZK, single-node ClickHouse
State
Functional; cosmetic OOS in Argo pending an ignoreDifferences rule

What it is

Used for traces and metrics from in-cluster workloads. The cosmetic OutOfSync in Argo CD is the K8s API-server adding default fields (schedulerName, dnsPolicy, terminationGracePeriodSeconds, etc.) that aren't in the source manifests; functionally the install is healthy.

Architecture

Add diagrams or topology notes here — how this component sits relative to DC/DR, what replicates, and what speaks to it. Mermaid blocks render as plain text today; embed images under /assets/ when needed.

Configuration

Add chart values overrides, important env vars, OIDC client config, secret references. Link to the source files in infra/gitops-rke2 rather than copying YAML wholesale — the repo is the source of truth.

Operations

Add runbook notes: backup, restore, common troubleshooting, dashboards, on-call cheatsheet entries.

Failover

Add DC/DR cutover/cutback notes: edge HAProxy backend name, healthcheck path, measured cutover/cutback times, smoke-test commands.
