RKM - Remote Kubernetes Monitoring

Simple monitoring tool for local and remote Kubernetes clusters.
Used technonlogies:

• Go
• Docker
• Bash
• InfluxDB
• Grafana

Architecture

Grafana Dashbaord

Installation

RKM Mission Control

Install InfluxDB

The RKM-Outpost metrics are stored in an InfluxDB.
If you don't already have an InfluxDB, install one for example with the InfluxDB Helm Chart on Kubernetes.
The InfluxDB and RKM-Outpost have a few dependencies:

1. The InfluxDB must be reachable for RKM-Outpost
2. An InfluxDB database for the RKM-Outpost metrics, for example "rkm"
3. User and password for the InfluxDB database

Install Grafana

If your don't have a Grafana instance, install one for example with the Grafana Helm Chart on Kubernetes. Grafana must have access to the InfluxDB database.
Add the InfluxDB database as a datasource to Grafana and import the RKM Mission Control Dashboard.

RKM Outpost

Install RKM Outpost Helm Chart:

1. Create rkm-outpost namespace:
   kubectl create namespace rkm-outpost

2. Create secret for InfluxDB authentication:
   kubectl create secret generic rkm-secrets --from-literal=INFLUXDB_USER=<user> --from-literal=INFLUXDB_PW=<password> -n rkm-outpost

3. Clone this repository:
   git clone https://github.com/onzack/rkm.git

4. Create and adjust the custom-values.yaml file for your cluster:
   cp ./rkm/deployments/kubernetes/helm/rkm-outpost/custom-values.yaml cluster-1-values.yaml
vim custom-values.yaml
   Importat
   rkm-outpost does not have proxy support yet. We are working on it.

5. Install Helm Chart:
   helm install -f custom-values.yaml -n rkm-outpost rkm-outpost ./rkm/deployments/kubernetes/helm/rkm-outpost
