Federated Edge Observability

Start Here

If you've followed a link to this repository, but are not really sure what it contains or how to use it, head over to Ansible Edge GitOps (which this pattern is derived from) for additional context and installation instructions

Basics & Setup

This Validated Pattern lays the OTEL based infrastructure foundation to setup observability in federated and/or distributed environments. The infrastructure components are a central OpenShift Hub server with 4 edge nodes which are running as preconfigured virtual machines on OpenShift-Virtualization (OCP-V).

The technology components used here are

• OpenShift,
• ArgoCD as OpenShift GitOps,
• Hashicorp Vault,
• OpenShift Virtualization,
• Ansible Automation Platform,
• OpenShift Data Foundations (ODF),
• Red Hat Device Edge (running at the edge),
• OpenTelemetry.

The installation at the OpenShift hub cluster happens via Operators (subscriptions), the pattern itself (see values-hub.yaml) or via an Ansible playbook (OTEL at the edge) while the installation at the edge happens via an Ansible playbook installing an RPM: https://github.com/validatedpatterns-demos/rhvp.federated_edge_observability/blob/main/roles/otel_collector/tasks/main.yml ArgoCD is managing the applications as defined in the values-hub.yaml file.

The user/password/key config happens in your user home (!) directory via the values-secret.yaml, so make sure you copy and then edit your values-secret.yaml.template to ~/values-secret.yaml.

There are several different git repositories in play which serve different purposes. The multiple git repos serve the purpose of easy customization and adoption into different environments.
