Cluster IQ

Cluster IQ is a tool for making stock of the Openshift Clusters and its resources running on the most common cloud providers and collects relevant information about the compute resources, access routes and billing.

Metrics and monitoring is not part of the scope of this project, the main purpose is to maintain and updated inventory of the clusters and offer a easier way to identify, manage, and estimate costs.

Supported cloud providers

The scope of the project is to cover make stock on the most common public cloud providers, but as the component dedicated to scrape data is decoupled, more providers could be included in the future.

The following table shows the compatibility matrix and which features are available for every cloud provider:

Cloud Provider	Compute Resources	Billing	Managing
AWS	Yes	Yes	No
Azure	No	No	No
GCP	No	No	No

Installation

This section explains how to deploy ClusterIQ and ClusterIQ Console.

Prerequisites:

Accounts Configuration

1. Create a folder called secrets for saving the cloud credentials. This folder is ignored on this repo to keep your credentials safe.

   mkdir secrets
   export CLUSTER_IQ_CREDENTIALS_FILE="./secrets/credentials"
   

   ⚠️ Please take care and don't include them on the repo.

2. Create your credentials file with the AWS credentials of the accounts you want to scrape. The file must follow the following format:

   echo "
   [ACCOUNT_NAME]
   provider = aws/gcp/azure
   user = XXXXXXX
   key = YYYYYYY
   " >> $CLUSTER_IQ_CREDENTIALS_FILE
   

   ⚠️ The values for provider are: aws, gcp and azure, but the scraping is only supported for aws by the moment. The credentials file should be placed on the path secrets/* to work with docker/podman-compose.

   ❗ This file structure was design to be generic, but it works differently depending on the cloud provider. For AWS, user refers to the ACCESS_KEY, and key refers to SECRET_ACCESS_KEY.

Openshift Deployment

1. Prepare your cluster and CLI

   oc login ...
   
   export NAMESPACE="cluster-iq"
   oc new-project $NAMESPACE

2. Create a secret containing this information is needed. To create the secret, use the following command:

   oc create secret generic credentials -n $NAMESPACE \
     --from-file=credentials=$CLUSTER_IQ_CREDENTIALS_FILE

3. Configure your cluster-iq deployment using ./deployments/openshift/00_config.yaml file. For more information about the supported parameters, check the Configuration Section.

   oc apply -n $NAMESPACE -f ./deployments/openshift/00_config.yaml

4. Create the Service Account for Cluster-IQ, and bind it with the anyuid SCC.

   oc apply -n $NAMESPACE -f ./deployments/openshift/01_service_account.yaml
   oc adm policy add-scc-to-user anyuid -z cluster-iq

5. Deploy and configure the Database:

   oc create configmap -n $NAMESPACE pgsql-init --from-file=init.sql=./db/sql/init.sql
   oc apply -n $NAMESPACE -f ./deployments/openshift/02_database.yaml

6. Deploy API:

   oc apply -n $NAMESPACE -f ./deployments/openshift/03_api.yaml

7. Reconfigure ConfigMap with API's route hostname.

   ROUTE_HOSTNAME=$(oc get route api -o jsonpath='{.spec.host}')
   oc get cm config -o yaml | sed 's/REACT_APP_CIQ_API_URL: .*/REACT_APP_CIQ_API_URL: https:\/\/'$ROUTE_HOSTNAME'\/api\/v1/

8. Deploy Scanner:

   oc apply -n $NAMESPACE -f ./deployments/openshift/04_scanner.yaml

9. Deploy Console:

   oc apply -n $NAMESPACE -f ./deployments/openshift/05_console.yaml

Local Deployment (for development)

For deploying ClusterIQ in local for development purposes, check the following document

Configuration

Available configuration via Env Vars:

Key	Value	Description
CIQ_API_HOST	string (Default: "127.0.0.1")	Inventory API listen host
CIQ_API_PORT	string (Default: "6379")	Inventory API listen port
CIQ_API_PUBLIC_HOST	string (Default: "")	Inventory API public endpoint
CIQ_DB_HOST	string (Default: "127.0.0.1")	Inventory database listen host
CIQ_DB_PORT	string (Default: "6379")	Inventory database listen port
CIQ_DB_PASS	string (Default: "")	Inventory database password
CIQ_CREDS_FILE	string (Default: "")	Cloud providers accounts credentials file

These variables are defined in ./<PROJECT_FOLDER>/.env to be used on Makefile and on ./<PROJECT_FOLDER>/deploy/openshift/config.yaml to deploy it on Openshift.

Scanners

As each cloud provider has a different API and because of this, a specific scanner adapted to the provider is required.

To build every available scanner, use the following makefile rules:

make build-scanners

By default, every build rule will be performed using the Dockerfile for each specific scanner

AWS Scanner

The scanner should run periodically to keep the inventory up to date.

# Building
make build-aws-scanner

API Server

The API server interacts between the UI and the DB.

# Building
make build-api

# Run
make start-api
