Answer is a powerful CLI application developed by NexClipper to monitor and manage Kubernetes clusters. It provides real-time metrics and alerts through a user-friendly interface, making it easy to troubleshoot and optimize system performance. In this tutorial, we will guide you through the steps to install Answer on Fedora CoreOS Latest.
The first step is to download the Answer binary from the official website. You can use the following command to download and extract the binary:
wget -O answer.tar.gz https://download.nexclipper.io/answer/1.7.0/answer-1.7.0-linux-amd64.tar.gz
tar -xzvf answer.tar.gz
Answer requires some dependencies to run properly. Use the following command to install the dependencies:
sudo dnf install -y python3 python3-pyyaml python3-psutil python3-requests python3-openpyxl python3-prometheus_client python3-google-auth python3-google-auth-oauthlib python3-google-auth-httplib2
After downloading and unpacking the binary, you need to move it to the /usr/local/bin
directory so that it can be accessed globally:
sudo mv answer /usr/local/bin/
To verify that everything is working correctly, run the following command:
answer version
If you see the version number of Answer displayed in the output, the installation was successful.
To configure Answer, create a configuration file named answer-config.yaml
in the /etc

sudo vi /etc/answer-config.yaml
Add the following to the file:
Clusters:
- Name: <cluster-name>
KubeConfig: <path-to-kubeconfig>
Monitoring:
Enabled: true

WebhookURL: <slack-webhook-url>
Replace the placeholders with appropriate values. The Name
