Info

This article instructs on explains how to create a DaemonSet in order to install and run one sample of Cloudaware Breeze agent on every node of a cloud-managed Kubernetes cluster . This allows to get the agent data from the cluster in Cloudaware CMDB.

...

(Amazon EKS, Azure AKS, Google GKE). Linux only.

Table of Contents

Prerequisites

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

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

Description

DaemonSet starts the container with Breeze agent installer. The container has two bind mounts:

  • host:/opt > container:/opt - used  used for the Breeze agent installation from container to the host file system

  • host:/ > container:/var/root - used  used for launching the agent in the chroot environment

The container runs two commands:

  1. Install the Breeze agent to the /opt directory.

  2. Run the simple daemon which runs the Breeze agent every 15 minutes

...

Create Docker Image

1. Download the Breeze agent installer and unpack it to the current directory:

...

  1. .

Steps

1. Open Cloudaware GitHub repo with Kubernetes files. Clone the repo to your Github using the following command:

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

2. Log in to Cloudaware account → Admin.

...

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

...

4. Select the file for Linux*:

...

*This integration is for Linux only.

5. Untar the Breeze installer and copy the extracted files (./breeze-agent folder) into kubernetes/daemonset folder of the cloned repo:

Code Block
cd breeze-tools/kubernetes/daemonset && tar xzvf <DOWNLOADS_PATH>/breeze-agent.example.version.0.x86_64.linux.tgz
tar xvzf

WHERE

breeze-agent.example.version.0.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

...

2. Build the Docker image:).

Code Block
docker build -t IMAGE_NAME .

...

ca-breeze-ds .

6. Create a repository in your private container registry (e.g. AWS ECR, Azure ACR, Google GCR, etc.) named ca-breeze-ds. Upload the result image to your private container registry.

Code Block
docker tag IMAGE_NAMEca-breeze-ds:latest DOCKER<CONTAINER_SERVERREGISTRY_HOSTNAME/IMAGE_NAME:latest
HOSTNAME>/ca-breeze-ds:latest
Code Block
docker push IMAGE_NAME:latest DOCKER_SERVER_HOSTNAME/IMAGE_NAME:latest

Run DaemonSet

...

<CONTAINER_REGISTRY_HOSTNAME>/ca-breeze-ds:latest 

WHERE

<CONTAINER_REGISTRY_HOSTNAME> is a placeholder that needs to be replaced by your private container registry URI (e.g. 111111111111.dkr.ecr.us-east-1.amazonaws.com/breeze-agent).

7. Edit the DaemonSet configuration file ds-breeze-agent.yaml and replace replacing the following placeholders with valid values:

  • DOCKER_SERVER_HOSTNAME

  • IMAGE_NAME

  • DOCKER_SERVER_SECRETS

2. Ensure that image pull secret is added to Kubernetes Secrets.

8. Create the new DaemonSet using the following command:

Code Block
kubectl create -f ds-breeze-agent.yaml

9. To verify that the DaemonSet has been created, run the command:

Code Block
kubectl get ds
