Breeze Agent Deployment for Kubernetes

This article explains how to install a Cloudaware Breeze agent on a Kubernetes cluster running in a private network. As a result, Breeze will be installed on all hosts within the cluster. NOTE: Linux only, except for AL2023, which is not currently supported.

Introduction

Deployment of the Breeze agent on a Kubernetes cluster serves two purposes:

To discover Kubernetes assets (nodes, pods, etc.) within a private Kubernetes cluster by establishing a TunHub connection.
By deploying Breeze on a cluster through a daemon set, you install Breeze on all hosts within the cluster. Alternatively, you can achieve this by installing Breeze on individual EC2 instances.

Breeze Agent Setup

1. Log in to Cloudaware account → Admin.

2. Find Breeze in the list of DevOps Integrations. Click 1 Configured.

3. Select the file for Linux*:

Breeze agent - deployment for Kubernetes - Breeze integrations - versions.png

*This integration is for Linux only.

4. Clone or download the breeze-tools repository from Cloudaware GitHub repo:

CODE

# git clone https://github.com/cloudaware/breeze-tools.git

5. Change the working directory to kubernetes, put the archive with Breeze agent installer and then extract it:

CODE

# cd breeze-tools/kubernetes/
# cp /path/to/agent/distro/breeze-agent.x86_64.linux.tgz .
# tar xf breeze-agent.x86_64.linux.tgz

WHERE

breeze-agent.x86_64.linux.tgz should be replaced by the name of the dowloaded installer file (e.g. breeze-agent.1x11xx1xxxx11x11111x1x1x.11111111.0.x86_64.linux.tgz).

6. Build docker images:

CODE

# docker build -t breeze-agent-init -f Dockerfile.breeze-agent-init .
# docker build -t breeze-agent -f Dockerfile.breeze-agent .

In order to check if images have been generated, the following command can be used:

CODE

# docker images "breeze*"

7. Create two repositories named 'breeze-agent' and 'breeze-agent-init' in your private Docker registry.

8. Push the created images to the PRIVATE Docker container registry:

CODE

# docker tag breeze-agent-init:latest CONTAINER_REGISTRY_URI/breeze-agent-init:latest
# docker push breeze-agent-init:latest CONTAINER_REGISTRY_URI/breeze-agent-init:latest
# docker tag breeze-agent:latest CONTAINER_REGISTRY_URI/breeze-agent:latest
# docker push breeze-agent:latest CONTAINER_REGISTRY_URI/breeze-agent:latest

WHERE

CONTAINER_REGISTRY_URI should be replaced by your private container registry URI (e.g. 111111111111.dkr.ecr.us-east-1.amazonaws.com/breeze-agent).

9. Open file breeze-agent-deployment-eks.yaml (for Amazon EKS) or breeze-agent-deployment-aks.yaml (for Azure AKS) in the text editor and replace the following placeholders with valid values:

CONTAINER_REGISTRY_URI - same as in the previous step
IMAGE_PULL_SECRET_NAME - name of the Kubernetes secret containing auth data of the private registry

10. Apply the configuration:

CODE

# kubectl create -f breeze-agent-deployment-eks.yaml

Check Status

Once Breeze is installed, Cloudaware automatically enables TunHub Gateway for a secure connection with Kubernetes which may be running in a private network.

Go back to Cloudaware Admin → Clouds & Integrations → TunHub. Ensure that the TunHub connection has been created and has a green status:

Check Cloudaware Access To EKS/AKS

Amazon EKS: ensure that Cloudaware has required permissions using this guide.

Azure AKS: ensure that Cloudaware has required permissions using this guide.

Please allow 1 hour for the data to load into Cloudaware.
